Some TV networks offer blind captioning on surround sound shows to help those with impaired vision. This involves mixing the soundtrack with audio narration and vocal descriptions of the on-screen action so the blind can experience the program. Some equipment types use special hardware connected to the audio/video receiver of a home-theater system to process and play the extra audio information. On other systems, you can activate or deactivate the blind captioning audio track using the remote control.

Pull out the AV receiver in the surround-sound system and turn it around to inspect the back of the component. Look for a connected black box labeled with the name of the audio-captioning service plugged into a set of inputs on the rear of the receiver.
Disconnect the cable or cables by pulling them straight out of the jacks on the receiver to detach the audio-captioning box, which you must also unplug from the electrical outlet. If you do not have this component, the blind-captioning service is supplied by the cable or satellite TV provider and you can manage it with the remote control.
Turn on the AV receiver's surround-sound system and play back an audio signal from the television.
Press and release the Audio or SAP button on the remote control until the blind-captioning track deactivates. You then hear only the standard soundtrack that accompanies the TV program.
