Method and apparatus for decoding and / or coding the video data using the residual prediction for enhancement layer bit-depth scalability

摘要

Scalable video bitstream, H. Has a base layer that is compatible with the 264 / AVC standard enhancement layer scalable and (BL) and (EL), scalability is showing a color bit depth. H. SVC extension of 264 / AVC scalability also provides the scalability of other types of space, such as scalability, for example, the number of pixels in the EL and BL is different. According to the invention, BL information is upsampled at the logical step two, the one is texture upsampling and the other is an up-sampling of the bit depth. The up-sampling the texture, it is a process of increasing the pixel number, the up-sampling of the bit depth is the process of increasing the number of values ​​that can be in response to the color intensity of pixels, each pixel having . BL data is up-sampled is used to predict the EL arranged, information BL is upsampled at the encoder side, the up-sampling at the decoder side as well, upsampling, and bit depth characteristics and spatial characteristics show.
