Abstract
There is provided an audio system and a method for expanding 7-channel audio using wireless transmission. The method includes transmitting first audio data corresponding to a plurality of first channels, transmitting second audio data corresponding to a plurality of second channels, receiving and extracting, by a first reception circuit, third audio data corresponding to three channels among the plurality of first channels, receiving and extracting, by the second reception circuit, fourth audio data corresponding to one channel among the plurality of first channels, and receiving and extracting, by the third reception circuit, fifth audio data corresponding to three channels among the plurality of second channels.
Claims18
An audio system comprising:
- a main audio device comprising:
- a first transmission circuit configured to transmit a first wireless audio signal comprising first audio data corresponding to a plurality of first channels, and
- a second transmission circuit configured to transmit a second wireless audio signal comprising second audio data corresponding to a plurality of second channels different from the plurality of first channels;
- a first auxiliary audio device comprising a first reception circuit configured to:
- receive the first wireless audio signal from the first transmission circuit and extract third audio data corresponding to three channels among the plurality of first channels from the first wireless audio signal;
- a second auxiliary audio device comprising a second reception circuit configured to:
- receive the first wireless audio signal from the first transmission circuit and extract fourth audio data corresponding to one channel among the plurality of first channels, different from the three channels among the plurality of first channels, from the first wireless audio signal;
- and
- a third auxiliary audio device comprising a third reception circuit configured to:
- receive the second wireless audio signal from the second transmission circuit and extract fifth audio data corresponding to three channels among the plurality of second channels from the second wireless audio signal,
- wherein the plurality of first channels comprises four channels and the plurality of second channels comprises three channels, and
- wherein the first auxiliary audio device is configured to extract three channels from the four channels, the second auxiliary audio device is configured to extract one channel from the four channels, and the third auxiliary audio device is configured to extracts all three channels among the plurality of second channels.
A method of expanding 7-channel audio using wireless transmission in an audio system, the method comprising:

- transmitting, by the second transmission circuit, a second wireless audio signal comprising second audio data corresponding to a plurality of second channels different from the plurality of first channels;
- receiving, by the first reception circuit, the first wireless audio signal from the first transmission circuit and extracting third audio data corresponding to three channels among the plurality of first channels from the first wireless audio signal;
- receiving, by the second reception circuit, the first wireless audio signal from the first transmission circuit and extracting fourth audio data corresponding to one channel among the plurality of first channels, different from the three channels among the plurality of first channels, from the first wireless audio signal;
- and
- receiving, by the third reception circuit, the second wireless audio signal from the second transmission circuit and extracting fifth audio data corresponding to three channels among the plurality of second channels from the second wireless audio signal,
- wherein the plurality of first channels comprises four channels and the plurality of second channels comprises three channels, and
- wherein the first reception circuit extracts three channels from the four channels, the second reception circuit extracts one channel from the four channels, and the third reception circuit extracts all three channels among the plurality of second channel.
