Which Is the Better Video Card?

8600. The newest models are always better and beating older video cards in performance, regardless of the memory. The 8600 might also have ddr3 memory which is much better than the other 2 video card's memorys but I do not know. If you did not know, Newegg.com has the cheapest prices

Which Is the Better Video Card? 1

1. NORTH MELBOURNES video?

Ok. Apparently the rubber chook is representing a guy and the chicken is a woman. Like how a guy uses a girl and then just diteches her. Thats what running over the chicken with a car bit means. Its pretty demented once you fin dout what it means. I mean honestly its pathetic.

2. Where can I get 75mm video film developed?

this is a Super8 film camera. Super8 film can be purchased on the internet, and processed at a few independent labs (kodak does not process movie film). forget the sound, super8 film is not available with magnetic audio track anymore. This is a professional camera that uses an amateur type film. this is dual speed, 18fps which is standard for super8 home use, and 24 fps which is theatrical (good luck finding a projector though). film comes in pre-loaded cartridges of about 3 minutes length (2,5 minutes at 24 fps). It is the correct vintage for the 60s as home movies were shot on film and not videotape. you can use *any* C-mount lens, but the one supplied with the camera is the most versatile as it offers servo zoom and auto iris. again, this is not video, it is motion picture film, not 75mm but Super8. you can pay to have the film scanned after processing to make a digital video file. or you can get a projector, dark room and silver screen.

3. Should I get a better video card for video quality?

You would be wasting your money. If what you want is better video quality you should upgrade your processor. Programs like VLC Media Player rely on CPU speed to adjust the quality of a video. If you want a better gaming experience, then upgrade your video card. nVidia and ATI are the best brands.

4. What is your favorite way to learn about catching fish?

Experience is the best teacher. Hands on is way better than any book, video and even Y/A. You can get ideas and see how it's done through books and videos but nothing beats old school, hands on, in your face knowledge! Good luck catchin'

5. Do they make an HDMI cable? DETAILS!!!...?

If you want to use the usb with hdmi. To answer your question, there is displayport cable that runs into a hdmi adapter. - DisplayPort into the usb out on computer, 1st hdmi cable into the hdmi out adapter to hdmi in on receiver, 2nd hdmi cable to hdmi out on receiver to hdmi in on tv. - Note sure how to get it all to work, and if it does audio, so sorry. Now instead of the above and if you want another method that uses hdmi, is to get a dvi-d s/pdif to hdmi converter. - dvi-d s/pdif outs on computer to ins on the converter, 1st hdmi cable into hdmi out on converter to hdmi in on receiver, 2nd hdmi cable to hdmi out on receiver to hdmi in on tv. There can be other methods like the above, but lets keep it simple. - Hdmi and dvi have about the same video quality. - Hdmi has better audio quality than s/pdif. If you do not care about sound quality or want a non hdmi way. - Dvi out on computer to dvi in on tv. (this cable does not carry audio). or - Dvi-d to hdmi cable (this cable does not carry audio). - For audio you will need to use s/pdif optical or s/pdif coaxial. (And thus the usb will work fine to tv video and audio, or the receivertv, so I can understand why you may want that). If you do not got dvi, then you can find a method in the pasted information below. For video audio: Best. - 1st hdmi cable to hdmi out on computer/laptop to hdmi in on receiver, then 2nd hdmi cable to hdmi out on receiver to hdmi in on tv. or - dvi-d s/pdif to hdmi converter. (Instead of to tv, you could go from receiver first, then hdmi from receiver to tv and maybe your receiver can upconvert other video signals other than hdmi-set the settings). For video: From best to least. - hdmi out on computer/laptop to hdmi in on tv. or - dvi out on computer/laptop to dvi in on tv. or - dvi-d to hdmi cable (does not carry audio). or - vga out on computer/laptop to vga in on tv. or - component out on computer/laptop to component in on tv. or - s video(super-video) out on computer/laptop to s video in on tv. or - composite video (video) out on computer/laptop to composite video in on tv. or - coax video out on computer/laptop to coax video in on tv. For audio: From best to least. - hdmi out on computer/laptop to hdmi in on receiver. or - s/pdif coaxial or s/pdif optical out on computer/laptop to s/pdif coaxial or s/pdif optical in on receiver. or - rca, Red (right channel) and white (left channel) stereo out on computer/laptop to in on receiver or tv. For audio: - You have to use a hdmi cable for audio if you have a 8 channel=7.1 surround sound speaker system hooked/wired up to your 7.1 receiver. You want to use hdmi cable for audio if your receiver supports the dolby-true-hd or dts-hd surround sound formats. - You need to download k-lite codec pack for windows media player or media player classic and use ffdshow (output -> ac3 s/pdif encode mode48000 hzmany other settings) to send a surround sound signal through a s/pdif cable. - If you have a sound card that supports multi-channel audio (select output 5.1 or 7.1.ect speaker setup). For video: - You need a video driver that supports multiple monitors and/or can use dual/clone view. or - If you cannot use the above (if your video driver is up to date and is not able to do multiple monitors or dual/clone view), - Method 1: Use a control center for your video driver or windows media center so you can set your tv as your primary monitormany other settings. (I have a ati display driver, so I downloaded a matching version of my ati display driver with ati/amd catalyst control center). - Method 2: Shut down computer, hook up video cable, disconnect your monitor (vga), turn tv onto either video 1 or hdmi or w/e works, then turn on computer and video will display on tv.

Analysis of Video Compression Technology in IP Video Communication
Analysis of Video Compression Technology in IP Video Communication
Different from general services, video is a streaming service with a large amount of data. For example, SIF format, NTSC format, color, 4:4:4 sampling in digital TV images, the amount of data per frame is 2028kb, and the data flow per second can reach 60.8mb; The data flow of color video in CCIR format, PAL format and 4 ∶ 4 ∶ 4 sampling can reach 148.8mbps. Experiments show that 176 × The YUV original video of 144 is transmitted on a 10Mbps LAN at a rate of about 3 frames / second. It can be seen that the effect of uncompressed video transmission on the Internet is intolerable, and it will easily swallow Internet resources, resulting in network congestion and even collapse. Therefore, the first step of IP video communication is video compression.The theoretical basis of video compression coding is information theory. Compression is to remove redundant information from both time domain and space domain, that is, to remove the inferred deterministic information. Coding methods can be roughly divided into three categories:1. Considering the statistical characteristics of image source, the prediction coding method, transform coding method, vector quantization coding method, subband wavelet coding method and neural network coding method are adopted;2. Considering the visual characteristics, the image coding method based on directional filtering and the coding method based on image contour / texture are adopted;3. Considering the scene characteristics of image transmission, the fractal coding and module based coding method are adopted.In the application of IP video communication, the choice of coding method should not only consider the compression ratio and signal-to-noise ratio, but also consider the complexity of the algorithm. Too complex coding algorithm may produce high compression ratio, but it will also bring large computational overhead. The software implementation will affect the real-time performance of communication. At present, among many video coding algorithms, MPEG and H.26X are the most influential and widely used algorithms.MPEG codingMPEG is an organization that formulates the dynamic video compression coding standard under the international organization for Standardization ISO / IEC. It has made a great contribution to the standardization and practicability of video compression coding technology. For example, MPEG-1 with 1.5mbps transmission rate for CD-ROM and MPEG-2 with more than 6Mbps transmission rate for HDTV have been successfully applied and created great commercial value. MPEG-4 is a very low rate coding standard for video conference and videophone. It integrates content-based retrieval and coding, and can directly access the compressed data content; The MPEG-7 standard, which will be completed in 2001, is called "multimedia content description interface". This standardized description can be added to any type of media information. Regardless of the expression or compression form of video information, multimedia data with this standardized description can be retrieved. Therefore, the application fields of MPEG-7 are mainly digital library and broadcast media.H. 263 codingH. 261 coding is a hybrid coding method of inter prediction to reduce time-domain redundancy and transform coding to reduce spatial redundancy. It has the advantages of high compression ratio and low algorithm complexity. One of the important application tools of MBone, the video coding of IVS adopts H.261 coding algorithm. On the basis of H.261, ITU-T launched H.263 coding standard in 1996. H. 263 has improved and expanded H.261 in many aspects. For example, on the basis of little increase in the complexity of coding algorithm, H.263 can provide better image quality and lower rate, which is very suitable for IP video conference and videophone applications. At present, H.263 coding is the most used coding method in IP video communication, and has been absorbed by many multimedia communication terminal standards, such as itu-th.310 (B-ISDN), H.320 (ISDN), H.324 (PSTN), H.323 (LAN, Wan, Internet).With the rapid improvement of computer performance, for applications such as videophone and video conference (generally using QCIF images), pure software encoder (codec) can meet the application requirements. The H.263 pure software encoder we implemented has a coding frame rate of more than 60 frames / s on the host with a main frequency of 166MHz, and the average image quality (expressed by signal-to-noise ratio) is greater than 38dB.H.263 launched by ITU-T in 1998 is the second version of H.263 recommendation. It provides 12 new negotiable modes and other features to further improve the compression coding performance. For example, there are only five video source formats in H.263 , H.263 allows more source formats, and there are also a variety of options for image shape and clock frequency, broadening the scope of application; Another important improvement is scalability, which allows multi display rate, multi rate and multi-resolution, and enhances the transmission of video information in heterogeneous network environment prone to bit error and packet loss. In addition, the image segmentation dependency of H.263 can also be limited to reduce error propagation. H. 263 improves the unrestricted motion vector mode in H.263, plus 12 new optional modes, which not only improves the coding performance, but also enhances the flexibility of application.

Where can I find home video studio installation on the Internet?If you want to convert any room into an inexpensive TV studio, your most important step is to select a problem-free space. A basement is a great spot, but you have to think about temperature control, it may be under a heavily traveled kitchen or corridor requiring you to insulate against the sound of footsteps, air conditioner noises, the roar of a furnace, the whine of a pump, or even the deedle-deedle of a nearby telephone or alarm can be very expensive to seal out.

How can I convert a cassette home video into a CD or DVD?The easiest way to to have a vcr's video output plugged into a dvd recorder's video input. Then play the tape on the vcr while recording on the dvd player. But if you can not play them you must not have a vcr. A lot of places that develop film also will convert home movies to dvd's for you. Check at a Walgreens or Rite Aide or something in the photo department6. Are study-at-home video classes for the CA IPCC exam useful?I think no .....If u r studying first time then you should never opt home based video classes (generally from youtube ) because it will not help to clear your concept in detail and dear you know,Concept will clear only by question-answers or doubts that you ask from teacherYou tube lectures not cover complete chapters and not helpful in series wise learning ...For repeative students...youtube Lectures help to guide some unclear concept or topic only .so do not think for money there is need of some investment for good return.Are study-at-home video classes for the CA IPCC exam useful?.7. do at home video game testers really exist or is that just the greatest scam ever?I am almost 100% sure there are genuine game tester jobs, but they are incredibly dull. I am an avid game fan, but I would not be a tester if I could help it. You tend to just get a small section to play over and over and over and over so that if you do it in a slightly different way that causes a bug/crash etc, they can pick up on it. From what I've heard the most successful testers are ones that play games at high end skill levels and enter tournaments etc, so that the company that developed the game notices them. For example, blizzard recruit a lot of the top gamers from starcraft and warcraft and stuff to just play games against each other (on their new starcraft 2 alpha/beta, for example) to test balance, strategies, get their opinions, etc. Balance testing is a big thing.8. Why do movies still come out in theaters first and then take months for the home video release?If the movie is a blockbuster it only takes around 3 or 4 months. Unless the company that made it has other plans about the release. For example take Deck the Halls and The Santa Clause wo not come out until the end of the year. Now 300 should be out by the end of July or the middle of August
FET Measurement Video
FET Measurement Video
FET characteristicsCompared with bipolar transistors, FET has the following characteristics.(1) FET is a voltage control device, which controls ID (drain current) through VGS (gate source voltage);(2) The control input current of FET is very small, so its input resistance is very large.(3) It uses most carriers to conduct electricity, so its temperature stability is good;(4) The voltage amplification factor of the amplification circuit composed of it is less than that of the amplification circuit composed of triode;(5) The radiation resistance of FET is strong;(6) Because it has no shot noise caused by disorderly moving electron diffusion, the noise is low.How to distinguish the three pins of FETG pole, needless to say, is easier to recognize.S-pole, whether p-channel or n-channel, is where the two lines intersect;The d-pole, whether p-channel or n-channel, is the side of the separate lead.Determine grid G: field effect tube pin diagram wiring diagram, turn the multimeter to R & times; 1K gear, connect the negative pole of the multimeter to any electrode, and the other probe contacts the other two poles in turn to measure their resistance. If the two measured resistance values are approximately equal, the negative probe contacts the grid, and the other two electrodes are the drain and source. Drain and source are interchanged. If the resistance measured twice is large, it is N channel; If the resistance measured twice is very small, it is P channel.Determine source s and drain D: there is a PN junction between source and drain. Therefore, according to the difference between the forward and reverse resistances of PN junction, s and D can be identified. Use the exchange probe method to measure the resistance twice, among which the one with low resistance value (generally thousands of ohms to tens of thousands of ohms) is the forward resistance. At this time, the black probe is pole s and the red probe is connected to pole D.Field effect tube pin determination method① Determination of grid G: use multimeter R × In gear 100, measure the forward and reverse resistance between any two pins. If the resistance measured at one time is hundreds of Ω), the two pins are D and s, and the third pin is g.② Drain D, source s and type determination: use multimeter R × Measure the forward and reverse resistance of D and s at 10K Ω gear, and the forward resistance is about 0.2 × 10K Ω, reverse resistance (5-1 ∞) x100k Ω. When measuring the reverse resistance, the red lead does not move. After the black lead is separated from the pin, touch g, and then go back to the original pin. There are two situations:a. If the reading changes from the original larger value to 0 (0 × 10K Ω), then the red probe is connected as s and the black probe is d. Contact g with a black probe is effective, so that the forward and reverse resistance between D and s of MOS tube is 0 Ω, which can also prove that the tube is n-channel.b. If the reading is still large and the black probe does not move, use the red probe to contact g, and return to the original foot immediately after touching. At this time, if the reading is 0 Ω, the black probe is connected to S pole and the red probe is d pole. It is effective to contact G pole with the red probe, and the MOS tube is P channel.Field effect tube measurement method(1) Discrimination of electrodes of Junction FET by resistance measurementAccording to the phenomenon that the forward and reverse resistance values of PN junction of FET are different, the three electrodes of Junction FET can be distinguished. Detailed method: dial the multimeter to R × On 1K gear, select any two electrodes and measure their forward and reverse resistance values respectively. When the forward and reverse resistance values of two electrodes are equal and thousands of ohms, the two electrodes are drain D and source s respectively. Since the drain and source are interchangeable for Junction FET, the remaining electrode must be grid G. The black lead (red lead is OK) of the multimeter can also contact one electrode arbitrarily, and the other lead can contact the other two electrodes in turn to measure its resistance value. When the resistance values measured twice are approximately equal, the electrode contacted by the black probe is the grid, and the other two electrodes are the drain and source respectively. If the two measured resistance values are large, it indicates that it is the reverse of PN junction, that is, it is the reverse resistance. It can be concluded that it is an n-channel FET, and the black probe is connected to the grid; If the resistance values measured twice are very small, it indicates that it is a positive PN junction, that is, a positive resistance. It is determined to be a p-channel FET, and the black probe is also connected to the grid. If the above situation is not present, the black and red probes can be exchanged and the test can be stopped according to the above method until the grid is identified.(2) Judging the quality of FET by measuring resistanceThe resistance measurement method is to use a multimeter to measure whether the resistance values between the source and drain, grid and source, grid and drain, grid G1 and grid G2 of the FET are consistent with the resistance values indicated in the FET manual to judge whether the FET is good or bad. Detailed method: first place the multimeter in R × 10 or R × In gear 100, measure the resistance between source s and drain D, usually in the range of tens of ohms to thousands of ohms (it can be seen in the manual that the resistance values of various types of tubes are different). If the measured resistance value is greater than the normal value, it may be due to poor internal contact; If the measured resistance is immeasurably large, it may be an internal broken pole. Then place the multimeter in R × 10K gear, re measure the resistance values between grid G1 and G2, between grid and source, and between grid and drain. When the measured resistance values are not large, it indicates that the tube is normal; If the measured resistance is too small or is a path, it indicates that the tube is broken. It should be noted that if two grids are broken in the tube, the component substitution method can be used for detection.(3) Estimation of amplification capacity of FET by inductive signal input methodDetailed method: use r of multimeter resistance × Gear 100, the red probe is connected to the source s, and the black probe is connected to the drain D. add 1 to the FET. 5V power supply voltage. At this time, the resistance between drain and source indicated by the meter needle. Then hold the gate g of the Junction FET by hand and add the induced voltage signal of the human body to the gate. In this way, due to the amplification of the tube, the drain source voltage VDS and drain current IB will change, that is, the resistance between the drain and source will change, so it can be observed that the watch needle has a large swing. If the swing of the grid pointer is small, the amplification ability of the tube is poor; The large swing of the watch needle indicates that the magnification of the tube can be large; If the needle doesn't move, the tube is broken.According to the above methods, we use the R of the multimeter × 100 gear, test Junction FET 3dj2f. Open the G pole of the tube first, and the measured drain source resistance RDS is 600 Ω. After holding the G pole by hand, the watch needle swings to the left, and the indicated resistance RDS is 12K Ω. The swing range of the watch needle is large, which shows that the tube is good and has great amplification ability.When using this method, we should clarify several points: first, when the test FET holds the grid by hand, the multimeter needle may swing to the right (the resistance value decreases) or to the left (the resistance value increases). This is due to the high AC voltage induced by the human body, and the working points of different FET when measured with resistance gear may be different (or working in saturated area or unsaturated area). The experiment shows that the RDS of most tubes increases, that is, the watch needle swings to the left; The RDS of a few tubes decreases, causing the needle to swing to the right. However, no matter what the swing direction of the watch needle is, as long as the swing range of the watch needle is large, it shows that the tube can be enlarged greatly. Second, this method is also applicable to MOS FET. However, it should be noted that the input resistance of MOS FET is high, and the allowable induced voltage of grid g should not be too high, so do not pinch the grid directly by hand. It must be used to hold the insulating handle of screwdriver and touch the grid with metal rod, so as to avoid human induced charge being directly added to the grid and causing grid breakdown. Third, after each measurement, a short circuit between G-S poles should be made. This is because the G-S junction capacitor will be charged with a small amount of charge, establish the VGS voltage, and the gauge needle may not move when the measurement is stopped. Only if the charge between the G-S poles is short circuited and released.(4) Discrimination of unmarked FET by resistance measurementFirst, use the method of measuring resistance to find out two pins with resistance value, that is, source s and drain D. the remaining two pins are the first grid G1 and the second grid G2. Write down the resistance value between source s and drain D measured with two probes, adjust the probes again, and write down the measured resistance value. For the one with larger resistance value measured twice, the electrode connected with the black probe is drain D; The red probe is connected to the source s. The s and D poles identified by this method can also be verified by estimating the amplification ability of their tubes, that is, the black pen with large amplification ability is connected to the D pole; The grounding of the red probe is 8 poles, and the test results of the two methods should be the same. After confirming the positions of drain D and source s, install the circuit according to the corresponding positions of D and s, and ordinary G1 and G2 will align with the positions in turn, which confirms the positions of the two grid G1 and G2, thus confirming the order of D, s, G1 and G2 pins.(5) Judging the transconductance by measuring the change of reverse resistanceWhen measuring the transconductance of VMOS n-channel enhanced FET, the red probe can be connected to the source s and the black probe to the drain D, which is equivalent to adding a reverse voltage between the source and drain. At this time, the grid is open and the reverse resistance of the tube is very unstable. Select the ohm gear of the multimeter at R × 10K Ω high resistance gear, and the voltage in the meter is high at this time. When touching the grid G by hand, it will be found that the reverse resistance of the tube changes obviously. The greater the change, the higher the transconductance of the tube; If the transconductance of the measured tube is very small, the reverse resistance changes little when measured by this method.
Have Video Games Gone to Far?
Have Video Games Gone to Far?
Have Video games gone to Far?its just a game dude. they put a mature stamp on it so that ideally, the people playing it can already separate fantasy from reality. and honestly, most of the people that are doing all the hating on xbl are either super drunk or else on something. or else it goes "aaah i hate you im gonna kill everybody and rape your corpse and wear your skin as a jacket GAME OVER oh good job guys that was a really fun game lets play again some time who wants to party up?".— — — — — —Is it true you don't have a life if you play video Games?But we judge anyways, we are humans after all, and we often express those judgments of other, regardless if they are right or wrong, because their based on personal perceptions. Take for example Bone Alone; I do not like his comments, his ground for which "has no life". I also do not like is immature username and picture… But who knows, I may actually be wrong on my judgment of his username and picture, he may have some highlighting and meaningful reason to have selected such a combination. Something other than the immature expression of posting a child with a shocked face, and changing the name of a movie to a more sexual term "Bone" to complete an illusion of perversion. Back to the main point. "People who camp out for a game just to be the first person to get a game has no life." The way I read this is: People who have dedication and commitment towards a hobby (or anything for that matter); have no life. Expressed by anyone camping out to get a video game, or camping out to get super bowl tickets, camping out to be the first person to vote in the polls for the next president of the United States; all apparently have no lives. Hell, I arrive at the barber shop early and wait for the doors to open so I can be the first person to get a haircut. I mean really, I got s**t to do I do not want to wait for 5 other people to get their hair cut first, but apparently I have no life because of it. Again I could be wrong on my judgment; you may only think this specifically towards video game related hobbies, you have a prejudice against gamers, where if it were any other hobby you would be fine with." Again: People who have dedication and commitment towards a hobby; have no life. Their reason, because it differs from your own, is now judged less meaningful. I do not even know how to express how wrong that is. Granted I do not really like people who play solely for points, trophies, and achievements, but I am not going to demean them for their reason for playing, that's just ethically wrong. "People who call in sick just to play a game has no life. Think chumlee from pawn stars who called in sick just so that he can play FIFA." I brought this one up more for the joke of it. Completely agree you should not call in sick just to play video games. By doing so you may be causing and increased workload on co-workers, if you really want to play some games then schedule some time off in advance; be responsible and mature. But Bone, common, you are trying to place judgment on other's lives as being less meaningful when YOU JUST REFFERENCED A REALITY TV SHOW. What does that say about your life?— — — — — —EMERGENCY!!!!! What is the best way to find video games tester jobs in your area?Yes, there are jobs as video game testers, but the name is decieving. You will probably need to have decent education in programming to be able to identify the many, many, many, MANY problems that you will encounter from playing, to answer your second question. Many people think that video game testers just sit around and play games all day, but this is NOT the case. Game testing is a long, tedious process that will leave you hating video games for the rest of your life. If you are a gamer, leave the testing to the professionals. Sorry to burst your bubble.

Best Video Games and Tech News Website??
Best Video Games and Tech News Website??
Best Video Games and Tech News Website??I would recommend a few websites to you. IGN is the biggest video game website out there. The have a lot of very interesting articles on all of the systems and review just about every game that comes out. New content is added all of the time, so it's worth checking out daily. They also have a "gear" sections which has technology articles, news, and reviews I would highly recommend them. Another great website is GamesRadar.com. This site does not do anything other than video games, but they are extremely good at what they do. I trust their reviews more than anyone's, and their opinion articles are absolutely hilarious (especially during their (week of hate" which just happened). Check out N4G.com as well. It does not have it's own content, but is rather a website that posts the most interresting video game news articles from all around the web. Here you will find articles from IGN, GamesRadar, GameSpot, Kotaku, Destructoid, and all of the other sites out there (I would recommend all of those sites as well if you are looking for more). It's a great one-stop-shop if you are looking for a quick update on what is happening in the world of gaming. As far as technology websites, I frequent Gizmodo.com and Dvice.com. I am not sure who owns Gizmodo, but Dvice is run by the SyFy network (though rest assured, the information on the sight is not science fiction). Both of these sights do an excellent job of presenting tech stories from all areas of technology. There are some pretty amazing pieces on there that I would recommend to anyone interested in tech.— — — — — —Can I get paid for playing video games?No, you cannot make a living off of playing video games. Unless you are amazing at one particular game and are lucky enough to get sponsors for whatever reason. You can get paid for testing them, like they do out in California. They always have conventions and what not and some of them pay the testers. You can be a video game tester and make. enough money to live. But it is not playing video games. And it's freelance work, you are not actually employed by a company. So there is no guaranteed work.— — — — — —How can I study instead of playing video games>?Study somewhere that does not HAVE video games. Study at school. Find a cubical. Do it in the car. Sit on the bleachers in the gym or field. Borrow a desk in your favorite teacher's classroom. Go to the library. Sit in the hall. Try the kitchen table. Study at a regular time. Before school. After school. During study hall (instead of talking about video games). At 7:00 every night. Right after (or right before) your shower. When you meet your sweety in the library. Use visual aids. Make your own flash cards. Draw pictures. Make your pictures symbolic. Think up songs or acronyms. Make a flow chart or time line. Use props as memory aids. Build a city/experiment/display for extra credit. Make fake tests (with answers) based in summary or questions at the end of each chapter. Diagram a devious plot to steel the Teacher's Edition of your text book. (mostly kidding on that one).— — — — — —I'm addicted to video games?It might be tough because once I just did not want to stop playing video games. All you have to do is like do something you like for example go outside or hang out with friends. If that does not help just try to resist yourself from playing video games. Hope this helps, best answer :)— — — — — —What is your opinion on girls that play video games?I am a girl. I think there's nothing special about it. It seriously annoys me nowadays how some girls brag about playing video games because they are a girl. It's no big deal. Do not brag or complain about someone partaking in a certain hobby because of their gender, it's childish. I wish your sister luck in quest to become a video game designer.— — — — — —Why are video games so addicting ?When I was still in the secondary school I played video games a lot simply because there was nothing better to do. I love hanging out with my friends, but I am not one of those people who enjoy hanging out for hours outside by simply goofing around outside or sitting on the bench doing nothing. Video games allow to socialize with other people online which is very fun indeed. Entertainment is always addictive. Now I work 40 hours a week and still play video games when got time, simply because it's fun activity ^_^ Though now when I am employed there's barely any time to play them compared to how much I played them in the past. Video games also are "stress killers". When a person is depressed or stressed out, gaming allows to cool that person off. There was actually a discussion about it not so long ago. Heh, the only positive thing I heard about games on the news in a long time. Sadly there's also real video game addiction to some people. People who try to hide from the own life in video games. These kind of people do not look for jobs, sit a home for weeks and barely socialize in real life. Reason? Life in video games is a lot more fun than in real life, simple as that.

It came on 5.25 floppy and I played it on a Tandy 1000. They made it for NES as well and I have played it on emulator recently. It was really ahead of it's time. It was as an rpg with several modes of play. While sailing it was a top down visual. There were sword fights which would have the outcome based upon the number of each swordfighters crew members and how well they fought. You could raid towns catch the silver train and strike it rich. If you did not handle the crew right or you did not cash out while you had a lot of gold the crew would mutiny.

Why Does My Laptop Skip on Video Playback?
Why Does My Laptop Skip on Video Playback?
Why does my laptop skip on video playback?Hmm, Its not the RAM issue first of all. Most probably its a CPU issue and could be software(most possibly) or hardware. Use resource manager of your OS like Task Manager (Windows), Activity Monitor(OSX), Gnome System Monitor (Linux) to see if the CPU usage is 100%. Upgrade also your OS to make sure you are running upto date system. Remember to specify your OS and other details of system and most notably processor =)— — — — — —Raspberry Pi 4B fast boot (buildroot) with support for hardware accelerated video playbackSince I got no feedback at all, I have now ordered a Rock Pi 4A with an M.2 SSD. It should be able to boot much faster than the Raspberry Pi 4B. Also got some help from the community there.— — — — — —Video playback loop using promise chaining and setTimeoutYou could try something like this:One of the best things of Typescript is the type safety. It's easier to keep track of the promises you are passing from one function to another if you declare them in the return type.In your case, where you just want a cleaner way to resolve a Promise, you can use Promise. resolve();. It's pretty straightforward to use and very useful. DOCS(Do not forget the parenthesis when calling onStart!)— — — — — —Question about the IPOD with video playback?I love my video ipod. I buy shows, movies, games, etc. from itunes. I bought my daughter one this year and she loves hers! You can buy itunes cards and download from their store— — — — — —120fps video playback issuesI have tried the example video on a fast computer with a high-level NVIDIA card.I have downloaded both MP4 versions : "High Quality (fast GPU)" and "Low Quality (slower GPU)". I use the K-Lite Mega Codec Pack.Playing the High Quality version, the results were very good and almost identical with either Windows Media Player, VLC or MPC-HC.However, playing the Low Quality version was impossible with Windows Media Player because of high pixelation and stuck video. The results were however good with VLC and MPC-HC.I hazard two conclusions :The Low Quality version is badly encoded in such a way that makes its playing impossible, at least with Windows Media Player (which uses K-Lite, while the others use mostly codecs that come packaged with them).Your computer specs may not be up to playing such videos at that speed, and this can be either because of the video card, memory, the bus, the disk, or even all of them.In the second case, using a good video converter may convert the videos to something you can watch.Try and see how you can play the High Quality version (life is full of surprises).— — — — — —Why is my computer crashing during video playback?it sounds like it is getting very hot. 1st clean your fans. next try setting it on a fan-cooled platform. This should bring down the temp significantly. i run speccy free from piriform and it tells me how hot my laptop are running.— — — — — —Why does YouTube video playback always lag when I switch to fullscreen/HD?Your video card determines how well the output video displays and operate. So even the computer may be FAST thanks to a good CPU, its video card can be outdated— — — — — —Secondary display for video playback onlyOK, done, but next time will someone tell me, that configuring X.server is fun, I will punch him right in the middle of his eyes.Anyway, the solution, that leads me to success, include AMD proprietary driver and VLC player. firstly, install AMD proprietary driver. Thanks to this thread I used somehow cleaner and should-be-safe procedure with installation code (recommended even if you have already fglrx installed, but experiencing troubles):now you can configure your setup withit will open C atalyst C ontrol C enterIn CCC you configure your displays as would esktop with one display' or something like that. I do not know exact english phrase, because I use translated GUI. Anyway, it should configure your displays as separate screen. now restart computer (or X). My computer behave strangely after boot, it needs one suspend & resume to work properly. Do not ask me why, but if you experienced abnormally laud GPU fan, you have probably the same problem and suspend & resume is one way around. For piece in mind, run CCC again and check your settings. now to the media player. If you do not have VLC yet, install it via App Center. Then open VLC, go to Tools->Setting andNOTE: solution described here makes all VLC settings permanent, which makes VLC one-purpose player only for video on secondary display. If you want use VLC for other purposes, you should run VLC with this settings set from command line, read VLC command line helpon the first panel 'Interface' uncheck 'embeed video in interface' and uncheck 'Show controls in fullscreen'(again, phrases may vary, because I have localized GUI in VLC too, thats one good thing about linux -> it localize all your apps by default). then go to Video tab and check 'Play in fullscreen' and set video output tothen turn to advanced/all (?) setting via radio button near left bottom corner.Then expand video->modules->x-window and set it to your desired X screen. Mine (and most probably yours) isInitials :0 means local display and following . 1 targets secondary screen. Primary display/screen is :0. 0. You can find your configured x screens and their numbers inthen should be all set. You can try play video with VLC and it should open on your secondary display fullscreen, while keeping VLC control interface on your primary screen. Only audio is played from your PC speakers/headphones. That we solve in VLC control interface under Audio->Audio devices, where we choose HDMI output. Then you hit CtrlL to switch VLC interface into playlist view and you have all your media fully under control.This procedure describe in short, what leads me to success. In your case, it shall not be as straightforward, because of LINUX. But if you do not understand something or have any problem, just ask.I had strange problems with fglrx driver and xorg. conf generated by amdcccle looked pretty normal, so I tried, if it will work with open-source radeon driver and guess what, it works! Just need a little modification (basically, just replace driver "fglrx" to driver "radeon", beware that there are multiple device sections).My working xorg.conf looks like this:You should backup your xorg.conf before uninstall fglrx, because it is removed during uninstallation process. Then you uninstall fglrx and reconfigure x-server like this:Then put back your modified xorg.conf and restart computer (or X). If nothing went wrong, you should see your separate screen config load under radeon driver. Only issue is missin HDMI audio, which you can solve by adding kernel parametermore useful informations can be obtained in documentation.
Research and Design of Intelligent Remote Video Monitoring System for Substation
Research and Design of Intelligent Remote Video Monitoring System for Substation
key word:Substation, video surveillance1、 System introductionNow, in order to improve economic benefits and labor productivity, the power sector is ready to realize unattended in the substation (substation). With the comprehensive transformation of the power sector network, each substation (substation) has a corresponding communication network, making remote monitoring possible. A monitoring center can be established in the power dispatching communication center, which can monitor and monitor the relevant data, parameters and images of each substation (substation), so as to understand and master the situation of each substation (substation) in real time and directly, and respond to the situation in time.At present, substations generally have "three remote" systems. On this basis, substation remote video monitoring system can be added, which is referred to as substation remote viewing system for short. The video data and monitoring data of the substation are collected and encoded by the equipment and video server at the front end of the substation, and the encoded data are transmitted to the monitoring center through the network, The monitoring center receives the encoded video data and monitoring data for monitoring, storage and management. The implementation of substation remote viewing system provides a powerful technical guarantee for realizing unattended substation and promoting the gradual development of power network management towards automation, integration, centralization and intelligence.2、 Demand analysisThe functions of substation remote viewing system are mainly reflected in the following aspects:Protect the safety of unattended substation equipment through image monitoring and security system.Through image monitoring, combined with the advantages of remote and local personnel operation experience, misoperation can be avoided.Monitor the operation status of field equipment through image monitoring, light linkage and environmental monitoring, so as to play the role of early warning and protection.Cooperate with other systems (such as substation integrated automation system, etc.).Main monitoring objects:Site environment in substation (substation).Appearance of main transformer and neutral grounding knife.Monitor the on / off status of outdoor circuit breaker, disconnector and grounding knife switch of substation (substation).Monitor each main equipment room in the substation (substation) (including gate, control room, relay protection room, communication room, high voltage room, etc.).3、 System compositionThe front end is connected to the embedded video encoder by the camera, intelligent switching value, analog quantity and other systems, which is converted into digital signals through video service. Generally, the substation can provide an E1 link.The substation remote viewing system adopts computer network transmission, and the digital video signal can be transmitted to the monitoring center through the laid network, which truly realizes the combination of multiple networks and one network. In addition, the signal transmission adopts the standard TCP / IP network protocol, which makes remote monitoring possible.The overall schematic diagram of substation remote viewing system is as follows:   The composition of the whole system is described below:The front-end monitoring site shall install a corresponding number of cameras and corresponding alarms (such as infrared alarm, smoke alarm, etc.) according to the specific conditions of the substation, and connect the camera video cable and control cable to the network video server. According to the different network video servers, each video server can be connected with 1-16 cameras. The network video server has a network interface, which can be directly connected to the switch to transmit images and related data to the network. If the substation has some analog quantities such as temperature and humidity, voltage and current to be monitored, IP data module (built-in RJ45 network port, directly connected to the network) and corresponding temperature and humidity sensor and electric quantity sensor can be configured to transmit relevant data to the monitoring center.A central monitoring server is configured in the dispatching and monitoring center of the power bureau, and the central server management software of the substation remote viewing system is installed, which is responsible for managing all cameras and video servers at the front end and all Internet monitoring users at the back end. Leaders and relevant personnel on duty only need to access the central monitoring server with IE browser. After obtaining authorization, they can monitor the front-end camera and obtain relevant data.The TV wall server can also be configured in the dispatching center. According to the number of video output channels, different numbers of TV wall decoding cards can be configured to directly decode and output analog video signals and send them to the TV wall for display. The images can be switched and displayed arbitrarily through the TV wall software.According to the networking mode, it is divided into three main parts: substation monitoring site, transmission network and dispatching monitoring center, which are introduced below.Substation monitoring siteThe on-site monitoring equipment of substation is mainly composed of video server, camera (protective cover, camera, lens and support), alarm, network bridge, network switch, data module, regulated power supply (optional) and other main equipment. It mainly completes the image acquisition, coding and transmission, camera control and alarm data input / output.One to several outdoor controllable spherical cameras (the controllable cameras need to be equipped with corresponding PTZ lens decoder) are installed in the outdoor field area of the substation according to the specific situation. The outdoor spherical cameras have good protection, can effectively prevent rain and defrost, and can be equipped with heaters and fans for automatic heating and automatic exhaust. The PTZ can rotate up, down, left and right, And the lens can be pulled far and close, which can monitor the field area in a wide range, and can monitor the main transformer, gate, etc. It is generally installed at the height of the house or at the appropriate place of the electric pole.The indoor controllable camera with zoom can be used in the main control room, which can scan the situation of the main control room in a wide range, and close-up the instrument panel in the main control room, so that the reading on the instrument panel can be seen more clearly.In the high-voltage room and other equipment rooms, a corresponding number of fixed cameras can be installed to observe the key parts.Corresponding alarms can be installed for key parts, including smoke detectors and temperature and humidity sensors in the equipment room, infrared double detection detectors and door magnetic switches at the door and window of the equipment room or main control room.Considering the need of anti-theft around the substation, it can be considered to configure corresponding infrared radiation detectors. Once someone crosses the fence and blocks infrared transmission, the alarm will alarm. At the same time, the video server can automatically record video. If the camera is linked, the camera can automatically rotate to point at the alarm.Considering the safety of equipment power supply, the monitoring equipment can be equipped with regulated power supply or UPS, and the corresponding video line control line lightning arrester can be considered.The video signal of the front-end camera is compressed into digital signal through the embedded network video server, and combined with other data signals into IP data packets. It is directly sent to the switch of the substation through the RJ-45 Ethernet port of the video server. The switch is connected with 2m Ethernet bridge and converted into 2m E1 special line signal for transmission to the monitoring center.communication networkAt present, there are two main transmission modes for video data transmission from substation to monitoring and dispatching center:1. Ethernet transmission modeThe channel from each substation to the monitoring center is the Ethernet interface directly, and the optical fiber or microwave transmission equipment directly provides the Ethernet interface. The image data signals of each substation are uploaded to the monitoring center through switches and routers at all levels.2. 2m Ethernet transmission modeThe channel from each substation to the monitoring center is 2m special line, and the communication equipment only provides 2m interface. The image data signal of the substation needs to be transformed into 2m interface through 2m Ethernet bridge, uploaded to the corresponding 2m Ethernet bridge of the monitoring center, transformed into network signal and entered the network of the monitoring center. In fact, it is equivalent to networking with 2m Ethernet bridge through 2m dedicated line.   Dispatching monitoring centerThe dispatching and monitoring center of power bureau is mainly composed of central monitoring management server, TV wall server, monitoring client terminal, etc. It mainly completes on-site image reception, user login management, priority allocation, control signal coordination, real-time image monitoring, video storage, retrieval, playback, backup, recovery, display switching of TV wall, etc.A high-performance server is placed in the central computer room of the power bureau, and the central server management software of the substation remote viewing system is installed. The central server manages all cameras, video servers and alarms at the front end and all monitoring clients at the back end.One or several monitoring clients are installed in the duty room, and IE can monitor and watch with a browser.
