Latest Patents
Leijun Dong holds a patent for a method and system for encoding and wirelessly transmitting stereo audio content. This patent discloses systems and methods to modify the Bluetooth mono HFP protocol to support bi-directional stereo operation for high bandwidth audio. The techniques leverage the larger packet size and longer duty cycle of the 2-EV5 transport packet. They expand the block size of the audio frames generated by the AAC-ELD codec to increase the maximum data throughput from the 64 kbps of the mono HFP protocol to 192 kbps using a stereo HFP protocol. The increased throughput not only supports stereo operations but also allows the transport of redundant or FEC packets for increased robustness against packet loss. In one aspect, the AAC-ELD codec may be configured for dynamic bit rate switching to flexibly perform trade-offs between audio quality and robustness against packet loss. The stereo HFP may configure the maximum throughput based on the desired audio quality.
