摘要： A scalable video bitstream may have an H.264/AVC compatible base layer and a scalable enhancement layer, where scalability refers to color bit depth. The H.264/AVC scalability extension SVC provides also other types of scalability, e.g. 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, one being texture upsampling and the other being bit depth upsampling. 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, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. The BL information is upsampled at the encoder side and in the same manner at the decoder side, wherein the upsampling refers to spatial and bit depth characteristics.

摘要： A scalable video bitstream may have an H.264/AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The H.264/AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled (TUp,BDUp) in two logical steps in adaptive order, one being texture upsampling and the other being bit depth upsampling. 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, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. A prediction order indication is transferred so that the decoder can upsample BL information in the same manner as the encoder, wherein the upsampling refers to spatial and bit depth characteristics.

摘要： A scalable video bitstream may have an H.264/AVC compatible base layer and a scalable enhancement layer, where scalability refers to color bit-depth. According to the invention, BL information is bit-depth upsampled using separate look-up tables for inverse tone mapping on two or more hierarchy levels, such as picture level, slice level or MB level. The look-up tables are differentially encoded and included in header information. Bit-depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled base layer data are used to predict the collocated enhancement layer, based on said look-up tables. The upsampling is done at the encoder side and in the same manner at the decoder side, wherein the upsampling may refer to temporal, spatial and bit depth characteristics. Thus, the bit-depth upsampling is compatible with texture upsampling.

摘要： Apparatus and methods are described for encoding and decoding an enhancement layer. A deblocking filter is applied at the enhancement layer for bit depth scalability. The deblocking filter is adjusted to remove coding artifacts caused by local inverse tone mapping for intra-layer texture prediction for the bit depth scalability. The boundary strength of the deblocking filter is adjusted based on a threshold that, in turn, is based on a difference of inverse tone mapping parameters for a block and an adjacent block.

摘要： A scalable video bitstream may have an H.264/AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The SVC standard allows spatial inter-layer prediction, wherein a residual in the EL is generated which is then intra coded. Another spatial intra-coding mode for EL is pure intra coding (I_N×N). The invention discloses a new intra-coding mode and two new inter coding modes, particularly for bit depth scalability. The new intra coding mode uses encoding of the residual between upsampled reconstructed BL and original EL, using mode selection. Two possible modes are residual prediction from BL and additional intra-coding of this residual. The new inter coding modes use also prediction of EL from reconstructed BL. In a first inter coding mode, the residual is encoded using Motion Estimation based on this residual. In a second inter coding mode, the residual is encoded using upsampled motion information from the BL.
