Video coding apparatus and method for supporting arbitrary-sized regions-of-interest

摘要

A computer readable storage medium has executable instructions to select a plurality of macroblocks in a video sequence to be coded as anchor macroblocks, the anchor macroblocks distributed across the video sequence and facilitating random access decoding of a portion of the video sequence. The video sequence is coded into a bit stream. Auxiliary information associated with the anchor macroblocks is generated. The auxiliary information associated with the anchor macroblocks is inserted in a supplementary section of the bit stream.
