Title: Innovations of Shyh-Shiaw Kuo
Introduction
Shyh-Shiaw Kuo is a prominent inventor based in Cupertino, California. He has made significant contributions to the field of audio technology, holding a total of eight patents. His work focuses on enhancing audio decoding methods and improving audio encoding techniques.
Latest Patents
One of Kuo's latest patents is for an enhanced audio decoder. This invention presents methods, systems, and apparatus for decoding an audio signal that includes bandwidth extension data. The decoder can receive an audio signal that consists of core audio data and bandwidth extension data. The core audio data is associated with a core portion of the audio signal, while the bandwidth extension data pertains to an extended portion. The invention allows for the generation of a decoded core audio signal in a time domain representation. Additionally, the extended portion of the audio signal can be reconstructed based on the extension data and the decoded core audio signal. The final output signal is generated by combining the lowpass filtered decoded core audio signal and the highpass filtered extended portion.
Another notable patent by Kuo is related to bitrate constrained variable bitrate audio encoding. This hybrid audio encoding technique incorporates both ABR (Adaptive Bitrate) or CBR (Constant Bitrate) and VBR (Variable Bitrate) encoding modes. The technique involves a two-loop quantization process that adaptively controls the final bitrate based on the encoding difficulty of the audio data. This innovation eliminates excessive bitrates commonly associated with conventional VBR mode while maintaining a more consistent perceptual sound quality compared to traditional CBR mode.
