Composite
Composite video which is also called CVBS or composite video blanking and sync is the format for analog television which only gives you a picture. It is later combined with sound signal. Composite video can easily be directed to any channel by modulating the right RF carrier. laser discs store a true composite signals, meanwhile VHS tapes use a somewhat modified composite signal. In home use the composite video is connected with an RCA jack that is usually yellow in color. When possible RGB is used instead of composite video with computers, video games consoles, and some DVD players.
Many devices send composite video to different devices. More older devices use composite video than do newer ones. The newer devices combine the element of sound and picture together which eliminates the need for composite video. The technology we have now is getting so much better that people don't need composite video as much as we use to. Piecing it together it's just not the same as having a feed together. Fiber optic cable lines have also played a part as you can send more over cable and fiber optic lines besides just an composite video.
Many people haven't been able to grasp composite video and what it does. Carry a picture only makes it tough for people to understand. Hopefully people will better understand it with more information. The real problem lies is once they have a grasp for composite video the next process in the ever growing chain of technology will be here and they will have to start all over which is never a good idea. One of the things that have setback composite video is HD products. The images just don't look as good on HD products and being compatible is also become a issue with it.
Hopefully in the future they will be able to fix these issues, but I sure doubt it as newer technology will arrive and make it just that much harder. in today's world we are moving so fast it sometimes very hard to keep up with things. Composite video could be just something in the long lines of things we have used before and don't need anymore. It's a shame how fast we lose things anymore in this age of technology. I don't see it letting up either.
