  • Parallel video parsing for video decoder processing
    Patent number: 11778211
    Abstract: Systems and methods of parallel image parsing and processing for video decoding are provided. Video decoder circuitry may enable an incoming encoded bitstream to be split into multiple bitstreams corresponding to the bitstream compression scheme and processed by multiple parsers corresponding to the bitstream compression scheme in parallel. This enables parallel decoding of the incoming bitstream and, thus, more efficient decoder processing.
    Type: Grant

  • Systems and Methods for Multi-Core Image Encoding
    Publication number: 20230102584
    Abstract: The present disclosure relates to systems and methods of multi-processing core processing of image frames during image encoding. The multiple processing cores may be connected via dedicated interfaces and transfer neighbor data between the processing cores to enable parallel processing of frame data. The multiple processing cores may each process quad-rows of image data for a single frame in parallel to reduce memory usage and mitigate latency in video encoding.

  • Systems and Methods for Luma or Chroma Statistics Collection
    Publication number: 20230085391
    Abstract: Systems and methods of analyzing the luma statistics or chroma statistics to correct for image artifacts in decoded images. Video decoder circuitry may enable luma statistics collection circuitry housed in the loop filters to collect luma samples during the last stage of the decoding process. This enables output of luma statistics data and output of the decoded image together.
