METHOD AND APPARATUS FOR INTRA MODE DERIVATION AND CODING IN SCALABLE VIDEO CODING

摘要

A method and apparatus of Intra mode coding for a scalable video coding system are disclosed. For a current Intra-coded block in the enhancement layer (EL), predictive coding is applied to the current Intra mode based on the base layer (BL) coding mode associated with the co-located block in the BL and neighboring coding modes associated with neighboring blocks of the current block in the EL. The neighboring blocks of the current block in the EL comprise a left block adjacent to a left side of the current block and a top block adjacent to a top side of the current block. One or more most probable modes (MPMs) can be derived from the neighboring coding modes and the BL coding mode, and the MPMs is then used for predictive coding of the current Intra mode.

1. A method of Intra mode coding for a scalable video coding system, wherein video data is configured into a Base Layer (BL) and an Enhancement Layer (EL), wherein the EL has higher spatial resolution or better video quality than the BL, a co-located block in the BL corresponding to a current block in the EL is coded before the current block, and the current block is Intra coded, the method comprising:
receiving information associated with a current Intra mode of the current block in the EL from a media or a processor; determining a BL coding mode associated with the co-located block in the BL; determining one or more neighboring coding modes associated with one or more neighboring blocks of the current block in the EL; and applying predictive coding to the current Intra mode based on the BL coding mode associated with the co-located block in the BL and said one or more neighboring coding modes associated with one or more neighboring blocks of the current block in the EL.
