Method and apparatus for decoding, and / or encoding video data using adaptive prediction order of the bit depth prediction and spatial prediction

摘要

Scalable video stream, H. Obtained here has a (EL) scalable enhancement layer (BL) and the base layer 264 / AVC compatible Scalability represents the color bit depth. H. 264 / AVC scalability extended SVC bring (for example, spatial scalability in the number of pixels in the EL and BL is different) other types of scalability. According to the present invention, a texture upsampling (TUp, BDUp), and the other is bit depth upsampling BL information is upsampled in adaptive logical order two steps. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values ​​corresponding to the pixel color intensities, each pixel can have. Predict the BL to use the BL data is up-sampled, collocated. prediction order indication is transferred that the decoder can upsample BL information as well as the encoder to allow for. Here, up-sampling to refer to the bit depth and spatial characteristics.
