A term often used when discussing a channel on a TV receiver or on video equipment, which has been especially designed to accept VCR audio-video signals. This channel automatically activates special circuitry within the TV set to prevent picture distortion and skewing. It is also used for audio-video processors, which handle both types of signals.

Some of these programs provided by the broadcast may not be free, you'll have to pay to view them. Coaxial cable is a copper cable used to connect cable signal coming from Cable TV Company to the TV. An analog encoded video signal that includes vertical and horizontal synchronizing information. Since both luminance (brightness) and chrominance (color) signals are encoded together, only a signal connection wire is needed. A composite video jack is usually a single RCA-type. Provides the highest possible color and picture resolution on the playback of digital signal source material like DVD players. The color difference signals (Pb, Pr) and the luminance(Y) signals are connected separately which allows for improved color bandwidth information (not possible when using composite video or S-Video connections). Letterbox refers to the image of a wide-screen picture on a standard 4:3 aspect ratio television screen, typically with block The brightness or black-and-white component of a color video signal. Determines the level of picture detail. National television system committee. The organization that developed the analog television standard currently in use in the U.S., Canada, and Japan. Now generally used to refer to that standard. The NTSC standard combines blue, red, and green signals modulated as an AM signal with an FM signal for audio. Separated video. An encoded video signal which separates the brightness from color data. S-Video can greatly improve the picture when connecting TVs to any high quality video source such as digital broadcast satellite (DBS) and DVDs. 29
