Multiple channel wireless communication system
First Claim
1. A wireless audio distribution system, comprising:
- a signal processor combining a plurality of pairs of stereo audio inputs and control codes into a serial digital bitstream;
a transmitter for wirelessly transmitting the serial digital bitstream;
a plurality of receivers responsive to the transmitted serial digital bitstream to each selectively produce one of the pairs of stereo audio in accordance with the control codes therein;
a local setting selector for causing each receiver to produce audio inputs in the serial digital bitstream selected by the local setting selector; and
a master settings selector causing a different audio input to be added to the digital bitstream and the operation of the local setting selectors to be overridden so that the receivers produce the different audio without regard to selections made by the local setting selectors associated with each of the plurality of receivers.

Abstract
A wireless audio distribution system may have a wireless transmitter, responsive to a plurality of audio input channels, for transmitting signals carrying the audio, a receiver, responsive to the transmitted signals for selecting one or more of the audio input channels to be reproduced in accordance with local setting selectors at the receiver. An additional audio source, such as a microphone, can be selectively used by for example the driver to talk on the cell phone or to make announcements to passengers via the wireless audio distribution system in accordance with a master settings selector which may be used to override local settings such as audio channel or volume selection.

6. A wireless audio distribution system, comprising:
-
a signal processor combining a plurality of audio inputs and control codes into a serial digital bitstream; a transmitter for wirelessly transmitting the serial digital bitstream; a receiver responsive to the transmitted serial digital bitstream to selectively produce audio in accordance with the control codes therein; a local setting selector for causing the receiver to produce audio related to one or more of the plurality of audio inputs in the serial digital bitstream selected by the local setting selector a plurality of additional receivers each responsive to the transmitted serial digital bit stream and each having a separately operable local setting selector for causing the receiver associated therewith to produce audio selected by the local setting selector; and a master settings selector for selectively overriding the operation of said local setting selectors to cause the receivers to produce audio related to a different audio input not selected by the local settings selectors, wherein the master the master settings selector causes the different audio to be applied to replace the plurality of audio inputs in the digital bitstream so that the different audio is produced by each of the plurality of receivers without regard to selections made by the local setting selectors associated with each of the plurality of receivers.
