Hiu-Fai R. Chan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Two Bins Per Clock CABAC Decoding
    Publication number: 20130259116
    Abstract: CABAC coefficient decoding may be increased to two bins per clock. Since coefficients comprise most of the bitstream, this improvement almost doubles the CABAC decoding for a low quantization parameter bitstream (with lots of coefficients).

  • CALVC Decoder With Multi-Symbol Run Before Parallel Decode
    Publication number: 20130259135
    Abstract: Context-adaptive variable length bitstream decoding performance may be improved and power consumption reduced by pushing the variable length decoding beyond one syntax element per clock pulse.

  • Configurable buffer allocation for multi-format video processing
    Patent number: 8484391
    Abstract: Systems and methods are described including dynamically configuring a shared buffer to support processing of at least two video read streams associated with different video codec formats. The methods may include determining a buffer write address within the shared buffer in response to a memory request associated with one read stream, and determining a different buffer write address within the shared buffer in response to a memory request associated with the other read stream.
