Abstract: A method for improved binarization and entropy coding process of syntax related to depth coding is disclosed. In one embodiment, a first value associated with the current depth block is bypass coded, where the first value corresponds to the residual magnitude of a block coded by an Intra or Inter SDC mode, the delta magnitude of a block coded by a DMM mode, or a residual sign of a block coded by the Inter SDC mode. In another embodiment, a first bin of a binary codeword is coded using arithmetic coding and the rest bins of the binary codeword are coded using bypass coding. The codeword corresponds to the residual magnitude of a block coded by the Intra or Inter SDC mode, or the delta DC magnitude of a block coded by the DMM mode.

Abstract translation: 公开了一种用于改进与深度编码相关的语法的二值化和熵编码处理的方法。 在一个实施例中，与当前深度块相关联的第一值被旁路编码，其中第一值对应于通过内部或内部SDC模式编码的块的剩余幅度，由DMM模式编码的块的增量幅度， 或通过Inter SDC模式编码的块的残余符号。 在另一个实施例中，使用算术编码对二进制码字的第一个二进制编码，并且使用旁路编码对二进制码字的其余的存储体进行编码。 码字对应于通过帧间或间隔SDC模式编码的块的剩余幅度或由DMM模式编码的块的增量DC幅度。

Abstract: A method and apparatus for significance map context selection are disclosed. According to the present invention, the TUs are divided into sub-blocks and at least two context sets are used. Non-DC transform coefficients in each sub-block are coded based on the same context, context set, or context formation. The context, context set, or context formation for each sub- block can be determined based on sub-block index in scan order, horizontal sub-block index, vertical sub-block index, video component type, TU width, TU height, or any combination of the above. In one embodiment, the sum of the horizontal and the vertical sub-block indexes is used to classify each sub-block into a class and the context, context set, or context formation is then determined according to the class.

Abstract: A method and apparatus for scalable video coding are disclosed, wherein the video data is configured into a Base Layer (BL) and an Enhancement Layer (EL) and wherein the EL has higher spatial resolution or better video quality than the BL. According to embodiments of the present invention, information from the base layer is exploited for coding the enhancement layer. The information coding for the enhancement layer includes CU structure, motion information, motion information, MVP/merge candidates, intra prediction mode, residual quadtree information, texture information, residual information, context adaptive entropy coding, Adaptive Lop Filter (ALF), Sample Adaptive Offset (SAO), and deblocking filter.
