METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR ASSESSING A MACROBLOCK CANDIDATE FOR CONVERSION TO A SKIPPED MACROBLOCK

摘要

A sequence of encoded data associated with a block of video is assessed to determine if: quantized coefficients of transformed residual pixel data associated with the block are equal to zero, the block was encoded using a temporal compression process, a slice that includes the block is configured to be encoded using only one reference picture list or two reference picture lists, the block is unpartitioned or was encoded in direct mode, a reference picture used to encode the block is the reference picture associated with a lowest index value on the one reference picture list, and an actual motion vector associated with the block is equal to a predicted motion vector associated with the block.

1. A method for assessing a sequence of encoded data associated with a block of video, comprising:
determining, via at least one electronic processing system, if quantized coefficients of transformed residual pixel data associated with the block are equal to zero; determining, via the at least one electronic processing system, if the block was encoded using a temporal compression process; determining, via the at least one electronic processing system, if a slice that includes the block is configured to be encoded using only one reference picture list; determining, via the at least one electronic processing system, if the block is unpartitioned; determining if a reference picture used to encode the block is the reference picture associated with a lowest index value on the one reference picture list; and determining, via the at least one electronic processing system, if an actual motion vector associated with the block is equal to a predicted motion vector associated with the block.
