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.

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.
