    Abstract: An apparatus and method for sample adaptive offset (SAO) to restore intensity shift of processed video data are disclosed. In an encoder side, the processed video data corresponding to reconstructed video data, deblocked-reconstructed video data, or adaptive loop filtered and deblocked-reconstructed video data are partitioned into regions smaller than a picture. The region partition information is signaled in a video bitstream located in a position before intensity offset values syntax. At the decoder side, the processed video data is partitioned into regions according to the partition information parsed from the bitstream at a position before intensity offset values syntax. Region-based SAO is applied to each region based on the intensity offset for the category of the region-based SAO type selected.

    Abstract: A method and apparatus for sharing context among different SAO syntax elements for a video coder are disclosed. Embodiments of the present invention apply CABAC coding to multiple SAO syntax elements according to a joint context model, wherein the multiple SAO syntax elements share the joint context. The multiple SAO syntax elements may correspond to SAO merge left flag and SAO merge up flag. The multiple SAO syntax elements may correspond to SAO merge left flags or merge up flags associated with different color components. The joint context model can be derived based on joint statistics of the multiple SAO syntax elements. Embodiments of the present invention code the SAO type index using truncated unary binarization, using CABAC with only one context, or using CABAC with context mode for the first bin associated with the SAO type index and with bypass mode for any remaining bin.

    Abstract: A method and apparatus for three-dimensional and scalable video coding are disclosed. Embodiments according to the present invention determine a motion information set associated with the video data, wherein at least part of the motion information set is made available or unavailable conditionally depending on the video data type. The video data type may correspond to depth data, texture data, a view associated with the video data in three-dimensional video coding, or a layer associated with the video data in scalable video coding. The motion information set is then provided for coding or decoding of the video data, other video data, or both. At least a flag may be used to indicate whether part of the motion information set is available or unavailable. Alternatively, a coding profile for the video data may be used to determine whether the motion information is available or not based on the video data type.

    Abstract: A method of SAO (sample-adaptive offset) processing is disclosed, where EO classification is based on a composite EO type group. The composite EO type group comprises at least one first EO type from a first EO type group and at least one second EO type from a second EO type group. The first EO type group determines the EO classification based on the current reconstructed pixel and two neighboring reconstructed pixels, and the second EO type group determines the EO classification based on weighted outputs of the current reconstructed pixel and a number of neighboring reconstructed pixels. A method of inter-layer SAO processing is also disclosed. An inter-layer reference picture for an enhancement layer is generated from the BL reconstructed picture and the inter-layer SAO information is determined, where at least a portion of the inter-layer SAO information is predicted or re-used from the BL SAO information.
