SCALABLE VIDEO CODING TECHNIQUES FOR SCALABLE BITDEPTHS

摘要

This disclosure describes video coding techniques that are executed in a bitdepth-based scalable video coding (SVC) scheme. Base layer video data and enhancement layer video data may be defined at different bitdepths. The techniques of this disclosure concern the coding of enhancement layer video blocks using a unique combination of inter-layer predictive coding modes after determining that inter-layer prediction should be used. In particular, two or more different inter-layer predictive coding modes may be utilized block corresponding to inter base layer blocks, and one of these inter-layer predictive coding modes may also be utilized for blocks corresponding to intra base layer blocks. Syntax information can be generated at the encoder and communicated with the bitstream, so that a decoder can use the proper inter-layer predictive coding mode in the decoding.
