units of width for every three units of height.

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.

programs provided by the broadcast may not be free, you’ll have to pay to view them.
Coaxial Cable Coaxial cable is a copper cable used to connect cable signal coming from Cable TV Company to the TV.

Input Connection
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).

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.

the picture when connecting TVs to any high quality video source such as digital broadcast satellite (DBS) and DVDs.
