Abstract:
1. A non-transitory medium, comprising executable instructions to: select a plurality of macroblocks in a video sequence to be coded as a plurality of anchor macroblocks, the anchor macroblocks distributed across the video sequence and facilitating random access decoding of a portion of the video sequence; code the video sequence into a bit stream by an encoder; generate auxiliary information associated with the anchor macroblocks; and insert the auxiliary information associated with the anchor macroblocks in a supplementary section of the bit stream, wherein the executable instructions to code the video sequence comprise executable instructions to code the anchor macroblocks using a DC intra prediction mode, and wherein the auxiliary information comprises luma DC prediction values for the anchor macroblocks and chroma DC prediction values for the anchor macroblocks.
