Definition: Analog Television refers to a video display device that receives and displays broadcast television signals that are transmitted utilizing technology that is similar to that used in standard radio transmissions. In fact, the video signal of analog television is transmitted in AM, while the audio is transmitted in FM.
Analog TV transmissions are subject to interference, such as ghosting and snow, depending on the distance and geographical location of the TV receiving the signal.
In addition, all analog television signals are transmitted in an interlaced format, in which all the odd lines in the image are transmitted first, then all even lines. These are referred to as fields. Two fields make up one frame of video image.
Full Power analog television broadcasting in the U.S. is scheduled to end by June 12, 2009.
