‐Generally understood to be the lowest quality video signal that you can use and is more appropriate for video delivery (broadcast) than as a source for content creation (video editing, DVD authoring, or encoding for the web).
‐The connectors common to composite video are RCA or Cinch for consumer equipment and BNC (Bayonet Neill‐Concelman.
‐As the quality of the RCA or BNC cable that is used increases, the noise and attenuation decreases.
• S‐Video:
‐Major advance in quality for consumer and professional video editors.
‐S‐Video splits the luma and chroma channels into two separate wire pairs, which eliminates generally half of the composite noise artifacts. The two chroma channels are still combined and still interfere with each other, leaving some noise in the signal.
‐While no longer considered true professional grade, it is a big improvement from composite and can be considered a good video capture minimum standard for editing and compression.
‐Mostly use a specific four‐pin connector on S‐Video cables. These cables are intended for short distances (usually 100 feet or less). Some types of professional and broadcast equipment use two BNC cables, one for luma and one for chroma, to carry S‐Video signals. This setup provides a connection that can be run farther and that can be locked into place to prevent the cable from falling out and losing the signal.
• Component analog:
‐Also known as YUV (Y for luminance, U for one chroma channel, and V for the other chroma channel) was the professional and broadcast standard for many years and it is still widely used today.
‐The luminance signal and the two color signals are all transmitted over their own dedicated cables. Because all three components or channels of the video signal are transmitted independently, the quality of the signal is quite high. Noise is very low and the colors in the video are richer and more precise.
‐In broadcast and professional environments, component analog has mostly yielded to digital video formats.
‐Component analog has become very popular in the consumer market, though,
as the preferred format for connecting home DVD players to new television sets
‐In professional environments, the component analog signals are carried by three individual BNC cables because of their ability to accommodate long runs and locking connections. In the new home
