Abstract
An audio description of a television program, i.e., a sound bite, is reproduced simultaneously with the display of the program at a television receiver. Specifically, the sound bite is embedded in a television signal that contains audio component and a video component. The television signal is transmitted to a plurality of television receivers and intercepted at one of the receivers. The video component is displayed on a monitor and the audio component is reproduced. On command the sound bite is reproduced instead of the audio component. An audio description of a television program, i.e., a sound bite, is also reproduced simultaneously with the display of a program listing of the program at a television receiver. Specifically, when the program listing is marked with an on-screen cursor, the sound bite is reproduced.
