Method and Apparatus of Slice Grouping for High Efficiency Video Coding

In the H.264/AVC standard, one of the new characteristics is the possibility of dividing an image in regions called slice groups. The use of slice groups provides various possible advantages such as prioritized transmission, error resilient transmission, and etc. The slice groups can be formed by flexible macroblock ordering (FMO), where each picture can be divided into slice groups in different scan patterns of the macroblocks. In the high efficiency video coding (HEVC) under development, a more flexible block structure, called coding unit (CU), is used as the unit to process video data. The picture is first divided into largest CUs (LCUs) and each LCU is adaptively split into smaller CUs using a quadtree until leaf CUs are reached. In the current HEVC development, there is neither slice nor slice group structure being considered. The LCU size used for HEVC is 16 times as large as the macroblock size used in the H.264/AVC standard. Therefore, it is very desirable to develop slice and slice group structure suited for HEVC to offer various benefits of error resilience, parallel processing, reduced line (row) buffer requirement, and etc. Accordingly, slice group types including raster scan type, vertical stripe type, regions of interest type and full flexibility type are developed for HEVC. Furthermore, various syntax elements are incorporated in the sequence header or the picture header to convey information associated with the slice group structure. 1. A method for coding of video pictures , wherein each of the video pictures is divided into a plurality of LCUs (largest coding units) , the method comprising:partitioning each of the video pictures into two or more slice groups according to a slice group type, wherein each of said two or more slice groups comprises one or more member LCUs of the plurality of LCUs and said wherein said each of said two or more slice groups is divided into one or more slices;processing said each of said two or more slice groups to ...

Method and Apparatus of Slice Boundary Filtering for High Efficiency Video Coding

An apparatus and method for video coding having intra-slice deblocking, intra-slice adaptive loop filter, and intra-slice adaptive offset are disclosed. In a video coding system, a picture is often divided into slices and each slice is independently processed so that errors or missing data from one slice cannot propagate to any other slice within the picture. In the recent high efficiency video coding (HEVC) development, deblock filtering (DF), adaptive loop filter (ALF) and adaptive offset (AO) may be applied to reconstructed slices. When the processing is applied across slice boundaries, it may rely on pixels outside the current slice and cause dependency of the current slice on other slice(s). Consequently, the DF/ALF/AO processing on a reconstructed slice may have to wait until the reconstructed slices that it is dependent from complete the DF/ALF/AO processing. To overcome the slice boundary issue, intra-slice DF/ALF/AO is developed that does not rely on any pixel outside the currently slice. An optional slice boundary filter may be applied to slice boundaries after all slices are processed by the intra-slice DF/ALF/AO.

Apparatus and Method for High Efficiency Video Coding Using Flexible Slice Structure

An apparatus and method for video coding based on flexible slice structure are disclosed. In the recent high efficiency video coding (HEVC) development, the slice may contain multiple LCUs instead of macroblocks. The LCU size being considered is 64×64 pixels which is much larger than the macroblock size of 16×16 pixels. Compared with the macroblock aligned slice for H.264, the LCU-aligned slice for HEVC does not provide enough granularities for dividing video frames. Consequently, a flexible slice structure is developed where slice partition is based on smaller coding units. In the flexible slice structure, the first LCU and the last LCU of the slice are allowed to be a fractional LCU, which is derived from a whole LCU using quadtree partition. Syntax elements are also developed to enable conveyance of flexible slice structure between an encoder and a decoder efficiently. 1.

Method and Apparatus of Delta Quantization Parameter Processing for High Efficiency Video Coding

In the current high efficiency video coding development, each LCU has its own quantization parameter (QP) and the difference between a current QP and a reference QP is transmitted instead of the QP value itself. Since the LCU is much larger than the macroblock of AVC/H.264, using one delta QP per LCU may cause rate control unable to adapt to the bitrate quickly enough. Consequently there is a need to adopt delta QP in units smaller than LCU to provide more granular rate control. Furthermore, it is desirable to develop a system that is capable of facilitating more flexible delta QP. Accordingly, adaptive quantization parameter processing is disclosed where a QP minimum CU size for incorporating or deriving a delta QP is indicated selectively in the slice level or in the sequence/picture level. In one variation, the delta QP is incorporated or derived only if nonzero quantized transform coefficients exist in a leaf CU that is larger than the QP minimum CU size. In another variation, quantization parameter information is only incorporated or derived when a leaf CU has any nonzero quantized transform coefficient. In yet another variation, a flag is used to indicate whether one delta QP per LCU is transmitted if the LCU has any nonzero quantized transform coefficient or one delta QP per leaf CU is transmitted if the leaf CU has any nonzero quantized transform coefficient.
