Abstract
A method for controlling two devices, separated from each other, during an audio muting mode operation. A control device causes an audio device to become muted during the audio muting mode. The control device also causes a video device to output a text service during the duration of the audio muting mode. Preferably, the text service corresponds to the audio portion of a media service.
