Abstract
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.
Claims21
1-25. (canceled)
An audio processing system, comprising:
- a processor;
- and
- a transmitter that is operatively coupled to the processor,
- wherein the processor determines a first number of channels available for audio in the transmitter, wherein the processor determines a second number of channels available in a remote receiver that is capable of receiving the audio, and wherein the processor causes 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.
An audio processing system, comprising:
- a processor;
- and
- a transmitter that is operatively coupled to the processor,
- wherein the processor delivers a plurality of channels of audio received from a primary source through the transmitter, wherein the processor selectively replaces at least one of the plurality of channels with the data from a secondary source for delivery through the transmitter, and wherein the processor assigns at least one of the plurality of channels to the secondary source for the duration of the delivery of the data and reassigns the at least one of the plurality of channels to the audio from the primary source after the delivery of the data.
An audio processing system, comprising:
- a primary source;
- a secondary source;
- a channel-allocator that allocates digital channels between the primary source and the secondary source, wherein the audio processing system is configured to multiplex signals from the primary source and the secondary source to produce a digital multiplexed transmission signal;
- a mixer that generates a combined audio signal from a plurality of audio channels provided by the primary source;
- a digital encoder that encodes the combined audio signal in to a digital stream;
- and
- a digital supplementary data encoder that encodes a supplementary data from the secondary source into the digital stream.
