A method and associated apparatus for providing random access to, and a gradual refresh of, encoded video sequences (Fig. E). Gradual decoder refresh is enabled through the use of isolated regions, flexible macro block order (Fig. 4), and turn-off of loop filter at slice boundaries. Mechanism are also provided for reliable detection of random access operations and for the reliable signaling of leading frames and open decoder refresh (ODR) picture. |
