Multiple channel wireless communication system
View Patent ↗A wireless audio distribution system having a wireless transmitter, responsive to a plurality of audio input channels, for transmitting a encoded digital bitstream serially combining each of the audio input channel, the encoded digital bitstream further including control data disbursed therein, a receiver, responsive to the transmitted encoded digital bitstream, for decoding and demultiplexing the digital bitstream, a manual selector switch, connected to the receiver device for selecting one or more of the audio input channels to be reproduced, and a sound producing device for selectively reproducing the one or more selected audio channels in accordance with the control data.
1. A wireless audio distribution system, comprising:
a wireless transmitter, responsive to a plurality of audio input channels, for transmitting an encoded digital bitstream serially combining each of the audio input channel, the encoded digital bitstream further including control data disbursed therein;
a receiver, responsive to the transmitted encoded digital bitstream, for decoding and demultiplexing the digital bitstream, the receiver including:
a manual selector switch for selecting one or more of the audio input channels to be decoded and demultiplexed by the receiver from the transmitted encoded digital bitstream; and
a sound producing device for selectively reproducing the one or more selected audio channels in accordance with the control data.
2. The invention of claim 1 further comprising:
an auto-off circuit automatically disconnecting power from the receiver when reproducible data from none of the audio input channels has been received for a predetermined time period.
3. The invention of claim 1 or 2 , wherein the receiver further comprises:
a comparator for comparing two segments in different fixed positions within the bitstream to detect an error event.
4. The invention of claim 3 , wherein the receiver further comprises:
a circuit for muting the selected audio input channels in response to a predetermined number of error events.
5. The invention of claim 4 , wherein the encoded bitstream further comprises:
a header section; and
a body section including a plurality of fixed sequences of data representing audio from each of the audio input channels, the sequences separated by control data.
6. The invention of claim 5 wherein the header further comprises:
synchronization signals for synchronizing the decoding of the digital bitstream with the transmission of that bitstream.
7. The invention of claim 6 wherein the wireless audio distribution system is positioned in a vehicle including a headliner and the wireless transmitter is positioned behind the headliner.
8. The invention of claim 1 , wherein the encoded bitstream further comprises:
a header section; and
a body section including a plurality of fixed sequences of data representing audio from each of the audio input channels, the sequences separated by control data.
9. The invention of claim 8 wherein the header further comprises:
synchronization signals for synchronizing the decoding of the digital bitstream with the transmission of that bitstream.
10. The invention of claim 9 wherein the wireless audio distribution system is positioned in a vehicle including a headliner and the wireless transmitter is positioned behind the headliner.
11. The invention of claim 1 wherein the wireless audio distribution system is positioned in a vehicle including a headliner and the wireless transmitter is positioned behind the headliner.
