A television set displays information as "audio-visual signals".
Television broadcasts are transmitted as audio-visual signals, which contain both visual (picture) and audio (sound) information. The television set receives these signals through an antenna or cable and then decodes them into pictures and sounds that are displayed on the screen.
The visual signal is displayed as a moving image on the screen, made up of pixels that create a picture. The audio signal is played through the TV's speakers, creating sound to accompany the picture. Together, the audio-visual signals provide a complete viewing experience for the audience.
While the antenna signals and cable signals provide the means for transmitting the audio-visual signals to the TV, they are not the information displayed on the screen. The information displayed on the screen is the result of the processing of the audio-visual signals by the TV set.
