    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.

    Abstract: A method and apparatus for processing of coded video using adaptive offset (AO) are disclosed. Embodiments of the present invention divide reconstructed video data into multiple filter units and apply adaptive offset to the filter units to generate filtered video data, where boundaries of filter units correspond to boundaries of coding units and each of said filter units contains at least one coding unit. Furthermore, two or more of the multiple filter units can be merged as indicated by a merge index to share the applied adaptive offset. A filter control flag can be used to indicate filter ON/OFF control. The luma and chroma components may also share the same filter information. In another embodiment, the filter information sharing among filter units can be applied regardless whether the boundaries of the filter units are aligned with the boundaries of the coding units.

    Abstract: A method of inter-layer or inter-view prediction for an inter-layer or inter-view video coding system is disclosed. The method includes receiving a to-be-processed block in the EL or the EV, determining a collocated block in the BL (Base layer) or the BV (Base View), wherein the collocated block is located at a location in the BL or the BV corresponding to the to-be-processed block in the EL (Enhancement Layer) or in the EV (Enhancement view), deriving a predictor for the to-be-processed block in the EL or the EV from the collocated block in the BL or the BV based on pixel data of the BL or the BV, wherein the predictor corresponds to a linear function of pixel data in the collocated block, and encoding or decoding the to-be-processed block in the EL or the EV using the predictor.

    Abstract: In one implementation, a method operates by receiving neighboring reconstructed first-color pixels and current reconstructed first-color pixels of a current first-color block and receiving neighboring reconstructed second-color pixels of a current second-color block collocated with the current first-color block. The method then determines linear model (LM) parameters according to a linear model for one or more LM Intra modes. The method then receives input data associated with current second-color pixels of the current second-color block and generates a cross-color Intra predictor from the current reconstructed first-color pixels of the current first-color block using the LM parameters associated with a LM Intra mode selected from said one or more LM Intra modes. Finally, the method applies cross-color Intra prediction encoding or decoding to the current second-color pixels of the current second-color block using the cross-color Intra predictor for the selected LM Intra mode.

    Abstract: A method and apparatus for loop filter processing of video data in a video encoder or decoder are disclosed. Embodiments according to the present invention conditionally allow sharing of loop filter parameters. In one embodiment, sharing of loop filter information between the current block and a neighboring block is determined according to a condition. If the condition indicates that sharing of loop filter information is allowed, a merge flag is coded and incorporated in the video bitstream in an encoder, and a merge flag is parsed from the video bitstream and decoded in a decoder. In one embodiment, the condition depends on region partitioning of the picture, where region partitioning partitions the picture into regions and the region may correspond to a slice or a tile. The condition is set to indicate that sharing of loop filter information is allowed if the block and the neighboring block are in a same slice/tile.

According to one embodiment of the present invention, the parameter is a quantization parameter corresponding to a neighboring slice or tile, and the quantization parameter is used for filter decision in deblocking filter.
