Abstract
Methods and systems for optimizing a routing of audio data to audio transmitting devices using a Bluetooth network are disclosed. One method includes receiving an encoded audio bitstream at a first speaker of the audio rendering system comprising a first and a second audio channels, separating a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream, generating a first encoded bitstream from the first set of spectral components, and forwarding the first encoded bitstream to a second speaker of the audio rendering system over the wireless link.
Claims19
An audio system comprising:
- a first device with a first processor;
- and
- a second device;
- wherein the first device is configured to transmit data to the second device over a wireless link;
- and
- wherein the first processor is configured to:
- receive an encoded audio bitstream comprising a first and a second audio channels;
- separate a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream;
- generate a first encoded bitstream from the first set of spectral components;
- and
- forward the first encoded bitstream to the second device over the wireless link.
A method for forwarding an audio bitstream in a system, the method comprising:
- receiving an encoded audio bitstream at a first device of the system comprising a first and a second audio channels;
- separating a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream;
- generating a first encoded bitstream from the first set of spectral components;
- and
- forwarding the first encoded bitstream to a second device of the audio rendering system over a wireless link.
A non-transitory computer readable storage medium, having stored thereon instructions that, when executed by a data-processing unit cause the data-processing unit to carry out the steps of a method, the method comprising:
- receiving an encoded audio bitstream at a first device of a system comprising a first and a second audio channels;
- separating a first set of spectral components of the first audio channel and a second set of spectral components of the second audio channel from the encoded audio bitstream, without decoding the audio bitstream;
- generating a first encoded bitstream from the first set of spectral components;
- and
- forwarding the first encoded bitstream to a second device of the audio rendering system over a wireless link.
