摘要： Deblocking filters used in video coding systems (e.g., single layer video coding systems or multi -layer video coding systems) may be enhanced. Inter layer prediction for scalable video coding (SVC) may be implemented using enhanced deblocking filters. Enhanced deblocking filters may be configured to be adapted, for example by adjusting a deblocking filter boundary strength calculation process. A deblocking filter boundary strength parameter may be assigned in accordance with, for example, a video block partition size of an input video block or a neighboring video block, whether an input video block or a neighboring video block was predicted using an inter layer reference, and/or whether at least one of an input video block or a neighboring video block have one or more corresponding base layer blocks that were coded using intra mode.

摘要： Systems, methods, and instrumentalities are disclosed for reference picture set mapping for scalable video coding. A device may receive an encoded scalable video stream comprising a base layer video stream and an enhancement layer video stream. The base layer video stream and the enhancement layer video streams may be encoded according to different video codecs.

The enhancement layer video stream may include inter-layer prediction information. The inter-layer prediction information may include information relating to the base layer coding structure. The inter-layer prediction information may identify one or more reference pictures available in a base layer decoded picture buffer (DPB). A decoder may use the inter-layer prediction information to decode the enhancement layer video stream.

摘要： A high-level signaling of adaptation parameters for facilitating reconstruction of, and/or used for reconstructing, decoded video is provided. In an embodiment, a method may includes selectively conveying adaptation parameters in a video bit stream using a signaling method selected from a set including (i) inserting adaptation parameters in a slice header, and (ii) inserting adaptation parameters in a dedicated network abstraction layer (NAL) unit. The method may include signaling the selection of the signaling method by a flag inserted to the slice header to indicate whether the adaptation parameters are obtainable from the dedicated NAL unit, or included in a current slice header. The flag, when set to a first value, may indicate that the adaptation parameters are retrievable or otherwise obtainable from the dedicated NAL unit. The flag, when set to a second value, may indicate that the adaptation parameters are retrievable or otherwise obtainable from the current slice.

摘要： Exemplary embodiments include systems and methods for coding a video comprising a plurality of pictures including a current picture, a first reference picture, and a second reference picture, where each picture includes a plurality of blocks. In one method, for at least a current block in the current picture, a number of available bi-prediction weights is determined based at least in part on a temporal layer and/or a quantization parameter of the current picture. From among available bi-prediction weights a pair of weights are identified. Using the identified weights, the current block is then predicted as a weighted sum of a first reference block in the first reference picture and a second reference block in the second reference picture. Encoding techniques are also described for efficient searching and selection of a pair of bi-prediction weights to use for prediction of a block.

摘要： Systems, methods, and Instrumentalities are described herein for calculating local Illumination compensation (LIC) parameters for bi-predicted coding unit (CU). The LIC parameters may be used to generate adjusted samples for the current CU and to address local illumination changes that may exist among temporal neighboring pictures. LIC parameters may be calculated based on bi-predicted reference template samples and template samples for a current CU. Bi-predicted reference template samples may be generated based on reference template samples neighboring temporal reference CUs. For example, the bi-predicted reference template samples may be generated based on averaging the reference template samples. The reference template samples may correspond to template samples for the current CU. A CU may be or may include a coding block and/or a sub-block that may be derived by dividing the coding block.
