Title: Innovations by Su Fu in Audio Communication
Introduction
Su Fu is an accomplished inventor based in Mountain View, CA (US). She has made significant contributions to the field of audio communication, particularly in enhancing Bluetooth technology for stereo audio transmission. Her innovative approach has led to the development of a unique patent that addresses the limitations of existing audio protocols.
Latest Patents
Su Fu holds a patent titled "Method and system for encoding and wirelessly transmitting stereo audio content for audio communication." 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, expanding the block size of audio frames generated by the AAC-ELD codec. This innovation increases 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 enhanced robustness against packet loss. Additionally, the AAC-ELD codec may be configured for dynamic bit rate switching, allowing for flexible trade-offs between audio quality and robustness against packet loss.
