And the quality of the base layer is limited by drift. In this paper, we propose a hybrid approach to eliminate the drift in an 11.263based video codec with two-layer scalability. The base layer decoder takes advantage of the minimal drift approach to obtain the reconstructed services that have the minimum drift. Then, the encoder sends an additional drift correction signal, which is used to eliminate drift completely, to the decoder. In this way, the proposed approach can eliminate the drift completely and reduce the overhead required for the drift correction. © 1999 IEEE. |
