摘要： An extension to the motion-constrained tile sets SEI message provides functionality to signal all tiles are independently decodable and to signal the ROIs that may have more than one tile per ROI. With this extension, the functionality to redefine any independently decodable region-of-interest in a CVS at a coding tree unit level based on user interactivity is enabled. The extension supports the interactivity utilized in various applications such as interactive Ultra High Definition Television (UHDTV), dynamic high-quality zoom-in application, interactive on-demand, e-learning, smart surveillance and many other applications. Additionally, the temporal MCTS SEI message is able to be used by an encoder for tiled streaming to signal explicitly to the decoder that the decoder need only to display the ROI.

摘要： An adaptive loop filter utilizing separable filters within a quadtree-based adaptive loop filter (QALF). The filters for at least the P and B pictures are replaced with a separable filter to provide Separable QALF (SQALF). In a preferred embodiment the filter comprises a Wiener filter as a best fit approximation of the non-separable filter. In response to decoding with the SQALF approach, computational complexity in the decoder is reduced without lowering perceived visual quality. Estimation of the separable filter is obtained in the encoder by iteratively minimizing the sum of squares error with the separable filter. The SQALF filtering is described within a video decoder.

摘要： An apparatus and method are taught for estimating an optimized sub-pixel interpolation filter using iterative and non-iterative estimations as needed for sub-pixel motion compensation and motion estimation in a video codec for improving coding efficiency. Motion vector information and mode decisions are passed from the first encoding stage which uses predetermined interpolation to at least a second encoding stage which uses an estimated adaptive interpolation filter determined during the first encoding stage. Processing overhead is reduced within the subsequent stages. Embodiments are described in which additional stages perform iterative encoding and estimation of interpolation filter in an n-th iteration.

摘要： Reducing contexts of a significance map includes merging some of the adjacent partitions of the higher frequency transform coefficients into one partition so that the significance of the coefficients in a merged partition are encoded with the same contexts. To reduce the impact of merging on coding efficiency of 4 x 4 blocks, the partitions of the lower frequency AC components of 4 x 4 blocks are not merged. To reduce the impact of merging on coding efficiency, the DC component is not merged with any AC component.

摘要： Described herein are apparatus and methods for enhancing perceived visual quality of video which has been coded using enhanced intra predictive coding referred to as boundary adaptive intra predictions (BAIP). BAIP is performed in response to the type of prediction, and the smoothness of the boundary between a current block and its neighboring pixels which have already been coded. Intra prediction is performed separately for each pixel along the left side and / or top side within a current block, which takes into account the pixel itself and multiple pixels along the left and /or top border of that current block. The BAIP technique can be applied for different block sizes, including 4 x 4, 8 x 8, and 16 x 16, and includes vertical, horizontal, and DC intra predictions.
