METHOD AND SYSTEM FOR INTER-LAYER PREDICTION MODE CODING IN SCALABLE VIDEO CODING

摘要

The present invention improves residue prediction by using MI even when the base layer MB is encoded in intra mode such as copying intra 4x4 mode of one 4x4 block in the base layer to multiple neighboring 4x4 blocks in the enhancement layer if the base layer resolution is lower than the enhancement layer resolution, using the intra 4x4 mode as intra 8x8 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 conditional coding of RP flag to save flag bits and reduce implementation complexity
