Multiple channel audio system supporting data channel replacement

摘要

An audio processing system is disclosed. The audio processing system may include a processor and a transmitter and may allow a surround sound system to utilize the transmission bandwidth efficiently by adaptively transmitting a supplementary data from a secondary source in addition to the audio signals of a primary source. The processor may determine a first number of channels available for audio in the transmitter and a second number of channels available in a remote receiver that is capable of receiving the audio. The processor may cause a secondary source to adaptively communicate a combination of data from a plurality of supplementary sources in some of a plurality of channels of the audio based upon the first number of channels and the second number of channels.

1. An audio processing system, comprising:
a processor; and a transmitter that is operatively coupled to the processor, the processor configured to: determine a first number of channels available for audio signals from a primary source in the transmitter; determine a second number of audio channels available in a remote receiver that is capable of receiving the audio signals from the primary source; compare the first number of channels with the second number of audio channels; determine that the first number of channels does not equal the second number of audio channels; cause a secondary source to adaptively communicate supplementary data in place of at least one of a plurality of channels reserved for the audio signals from the primary source based at least in part upon the determination that the first number of channels does not equal the second number of audio channels.
