发明名称 A METHOD FOR RANDOM ACCESS AND GRADUAL PICTURE REFRESH IN VIDEO CODING
摘要 A Method, And Associated Apparatus for providing random access to, and gradual refresh of, encoded video sequences. Gradual decoder refresh is enabled through the use of isolated regions, flexible macroblock order, and turn-off of loop filter at slice boundaries. Mechanisms are also provided for reliable detection of random access operations and for the reliable signaling of leading frames and ODR (open decoder refresh) pictures.
