摘要： Cross-component prediction (CCP) and adaptive color transform (ACT) may be performed concurrently in a video coding system. CCP and ACT may be enabled/disabled at the same level (e.g. at the transform unit level) via an indicator signaled in the bitstream such as the ACT enable indicator for the CU. Inverse CCP and ACT may be operated at the same level (e.g. at the transform unit level). Prediction residuals may be converted to original color space without waiting for reconstruction of luma and chroma residuals of an entire prediction unit or coding unit. CCP and ACT transforms may be combined into one process to reduce encoding/decoding latency. Differences in dynamic ranges of color components may be compensated by variable dynamic range adjustments. Differences in bit depths between luma and chroma components may be compensated by selectively disabling the ACT coding tool, scaling a component output of the CCP, adjusting a quantization parameters (QPs) and/or shifting a component output of an inverse transform of the video coding system.
摘要翻译：跨分量预测（CCP）和自适应颜色变换（ACT）可以在视频编码系统中同时执行。 CCP和ACT可以经由比特流中指示的指示符（例如CU的ACT使能指示符）在相同级别（例如，在变换单元级别）处被允许/禁止。反相CCP和ACT可以在相同的电平（例如，在变换单元级）上操作。可以将预测残差转换成原色空间，而不用等待整个预测单元或编码单元的亮度和色度残差的重建。 CCP和ACT转换可以组合成一个过程以减少编码/解码延迟。可以通过可变动态范围调整来补偿颜色分量的动态范围的差异。可以通过选择性地禁用ACT编码工具，缩放CCP的分量输出，调整量化参数（QPs）和/或移动视频编码的逆变换的分量输出来补偿亮度和色度分量之间的位深度的差异系统。

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 provided to implement motion information signaling for scalable video coding. A video coding device may generate a video bitstream comprising a plurality of base layer pictures and a plurality of corresponding enhancement layer pictures. The video coding device may identify a prediction unit (PU) of one of the enhancement layer pictures. The video coding device may determine whether the PU uses an inter-layer reference picture of the enhancement layer picture as a reference picture. The video coding device may set motion vector information associated with the inter-layer reference picture of enhancement layer to a value indicative of zero motion, e.g., if the PU uses the inter-layer reference layer picture as the reference picture.

摘要： Systems and methods are described for video coding using affine motion models with adaptive precision. In an example, a block of video is encoded in a bitstream using an affine motion model, where the affine motion model is characterized by at least two motion vectors. A precision is selected for each of the motion vectors, and the selected precisions are signaled in the bitstream. In some embodiments, the precisions are signaled by including in the bitstream information that identifies one of a plurality of elements in a selected predetermined precision set. The identified element indicates the precision of each of the motion vectors that characterize the affine motion model. In some embodiments, the precision set to be used is signaled expressly in the bitstream; in other embodiments, the precision set may be inferred, e.g., from the block size, block shape or temporal layer.

摘要： A secondary content such as an advertisement may be inserted based on users' interests in 360 degree video streaming. Users may have different interests and may watch different areas within a 360 degree video. The information about area(s) of 360 degree scenes that users watch the most may be used to select an ad(s) relevant to their interests. One or more secondary content viewports may be defined within a 360 degree video frame. Secondary content viewport parameter(s) may be tracked. For example, statistics of the user's head orientation for some time leading to tile presentation of the ad(s) may be collected. Secondary content may be determined based on the tracked secondary content viewport parameters).

摘要： Systems, methods, and instrumentalities are disclosed for discontinuous face boundary filtering for 360-degree video coding. A face discontinuity may be filtered (e.g., to reduce seam artifacts) in whole or in part, for example, using coded samples or padded samples on either side of the face discontinuity. Filtering may be applied, for example, as an in-loop filter or a post-processing step. 2D positional information related to two sides of the face discontinuity may be signaled in a video bitstream so that filtering may be applied independent of projection formats and/or frame packing techniques.
