METHOD AND APPARATUS FOR ENCODING AND/OR DECODING VIDEO DATA USING ENHANCEMENT LAYER RESIDUAL PREDICTION FOR BIT DEPTH SCALABILITY

摘要

The scalable video bit-stream H.264 / AVC compatible base layer (BL) and a scalable enhancement may have a layer (EL), where scalability refers to color bit depth. H.264 / AVC scalability extension SVC, different types of scalability, e.g., provide spatial scalability, where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled in two logical steps in the texture upsampling and bit depth upsampling (TUp, BDUp). Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have pixels corresponding to the color intensity. BL up-sampled data is used to predict the arranged EL. BL information is upsampled at the encoder side, the same side as well, and the decoder, the upsampling refers to spatial and bit depth characteristics characteristics.
