    Abstract: A method and apparatus for 3D video coding system are disclosed. Embodiments according to the present invention apply SAO process (sample adaptive offset process) to at least one dependent-view image of the processed multi-view images if processed multi-view images are received. Also embodiments according to the present invention apply the SAO process to at least one dependent-view image of the processed multi-view images or at least one depth map of the processed multi-view depth maps if both processed multi-view images and the processed multi-view depth maps are received. The SAO can be applied to each color component of the processed multi-view images or the processed multi-view depth maps. The SAO parameters associated with a target region in one dependent-view image or in one depth map corresponding to one view may share or may be predicted by second SAO parameters associated with a source region corresponding to another view.

    Abstract: A method and apparatus for sharing information in a video decoding system are disclosed. The method derives reconstructed data for a picture from a bitstream, where the picture is partitioned into multiple slices. An information-sharing flag is parsed from the bitstream associated with a current reconstructed slice. If the information-sharing flag indicates information sharing, shared information is determined from a part of the bitstream not corresponding to the current reconstructed slice, and in-loop filtering process is applied to the current reconstructed slice according to the shared information. If the information-sharing flag indicates filter no information sharing, individual information is determined from a part of the bitstream corresponding to the current reconstructed slice, and in-loop filtering process is applied to the current reconstructed slice according to the individual information. A method for a corresponding encoder is also disclosed.

    Abstract: A method and apparatus for inter-layer prediction for scalable video coding are disclosed. Embodiments of the present invention utilize weighted prediction for scalable coding. The weighted prediction is based on the predicted texture data and the inter-layer Intra prediction data derived from BL reconstructed data. The inter-layer Intra prediction data corresponds to the BL reconstructed data or up-sampled BL reconstructed data. The predicted texture data corresponds to spatial Intra prediction data or motion-compensated prediction data based on the second EL video data in the same layer as the current EL picture. Embodiments of the present invention also utilize the reference picture list including an inter-layer reference picture (ILRP) corresponding to BL reconstructed texture frame or up-sampled BL reconstructed texture frame for Inter prediction of EL video data. The motion vector is limited to a range around (0,0) when the ILRP is selected as a reference picture.
