Abstract:
A Bluetooth component (e.g., a Bluetooth chip) and a digital signal processing (DSP) component (e.g., an audio DSP) of a device may directly handle link condition sensing (e.g., link quality monitoring) and audio bitrate determination. The Bluetooth component may perform link condition sensing (e.g., link quality monitoring) and the Bluetooth component and/or the DSP component may perform link condition processing and audio bitrate determination. Encoding scheme (e.g., audio bitrate) determination and modification may be performed independently by the Bluetooth component and DSP component, such that encoding schemes may be adapted to link conditions while other hardware (e.g., connected to the DSP) is operating in a low power or sleep state. In some cases, the Bluetooth component may sense link conditions and transmit bitrate information directly to audio encoding blocks of the DSP component.
