<P>PROBLEM TO BE SOLVED: To reduce redundancy present between SVC layers. <P>SOLUTION: The present invention improves residue prediction by using MI even when the base layer MB is encoded in intra mode such as copying intra 4×4 mode of one 4×4 block in the base layer to multiple neighboring 4×4 blocks in the enhancement layer if the base layer resolution is lower than the enhancement layer resolution, using the intra 4×4 mode as intra 8×8 mode if the base layer resolution is lower than the enhancement layer resolution and the base layer resolution is half of the enhancement layer resolution in both dimensions, carrying out direct calculation of the base layer prediction residue used in RP, clipping of prediction residue for reducing memory requirement and tunneling of prediction residue in BLTP mode; and carrying out conditional coding of RP flag to save flag bits and reduce implementation complexity. <P>COPYRIGHT: (C)2012,JPO&INPIT |
