Appendix
•SECAM (Sequentiel Couleur à Mémoire)—a 50 Hz 768x576 resolution standard similar to PAL used in France, Eastern Europe, and some African and Middle Eastern countries. PAL and SECAM differ in the way color information is encoded on the broadcast signal.
Video produced by VCRs, laser disc players, and camcorders is sent and received in one of two formats:
•Composite video—carries sync, luminance (the black and white part of the video signal), and color information on one signal with a single pin and ground connection, and
•S-Video—separates color information from the luminance and sync signal with a four-pin and ground connection. Because of the color separation, S-Video produces a higher quality display with better colors and less noise. It is not recommended for use over distant connections as the signal tends to degrade the longer the it must travel.
About computer video
Computer video generates five separate signals for IBM compatible computers: red, green, blue, H-sync and V-sync. It provides four separate signals for Macintosh computers: red, green, blue, and composite sync. These types of signal are called RGB for red, green, and blue.
