摘要： A method and apparatus for palette prediction and sharing according to the present invention are disclosed. A method incorporating an embodiment of the present invention determines one or more palette sharing flags for the current block. A set of current palettes corresponding to the set of color components is generated according to the palette sharing flags. If a first palette sharing flag is asserted, one or more current palettes indicated by the first palette sharing flag are copied entirely from one or more reference palettes of a set of reference palettes. If the first palette sharing flag is not asserted, one or more current palettes indicated by the first palette sharing flag are derived from a bitstream associated with the video data. Encoding or decoding is then applied to the current block according to the set of current palettes.

摘要： Various implementations are directed to providing inter-layer dependency information. In one implementation, syntax elements are generated that indicate an inter-layer dependency structure among three-dimensional video (3DV) layers. Based on the inter-layer dependency structure, an inter-layer reference is identified for a picture from a layer of the 3DV layers. The picture is encoded based, at least in part, on the inter-layer reference. Corresponding decoding implementations are also provided. Additionally, in another implementation, a transmission priority and an indication of network congestion are used to determine whether to transmit data for a particular 3DV layer. The transmission priority is based on an inter-layer dependency structure among multiple 3DV layers. Another implementation is directed to a network abstraction layer unit that can explicitly identify and convey inter-layer references and corresponding dependencies.

摘要： A method of video coding using palette coding mode for color video in a non-444 color format is disclosed. The non-444 video data can be converted to the 444 format so that the palette designed for the 444 format can be used for the non-444 video data. For the 4:2:0 color format, each chroma sample collocated with corresponding quad luma samples is padded with three chroma samples to form converted quad chroma samples. For the 4:2:0 color format, if a current pixel does not belong to the color palette, one or more escape values are signaled for the current pixel and the escape value associated with the chroma sample of the current pixel for each color component is not signaled for three of the quad chroma sample locations collocated with corresponding quad luma samples.
摘要翻译：公开了一种使用调色板编码模式进行彩色视频的非444色格式的视频编码方法。非444视频数据可以转换为444格式，以便为444格式设计的调色板可用于非444视频数据。对于4：2：0颜色格式，用相应的四个亮度样本并置的每个色度样本用三个色度样本填充以形成转换的四色度样本。对于4：2：0颜色格式，如果当前像素不属于调色板，则会为当前像素发出一个或多个转义值，并为每个颜色分量与当前像素的色度样本相关联的转义值对于与相应的四亮度样本并置的四个色度采样位置中的三个没有发出信号。

摘要： A method of IntraBC coding using restricted reference area is disclosed. A reference block is selected from an available ladder-shaped reference area comprising previously processed blocks before the current working block in the current CTU row and previously processed blocks in one or more previous CTU rows. A location of a last previously processed block of a second previous CTU row that is one CTU row farther away from the current CTU row than a first previous CTU row is always in a same vertical location or after a same vertical position of a last previously processed block of the first previous CTU row. The current picture may be partitioned into multiple CTU rows for applying wavefront parallel processing (WPP) on the multiple CTU rows, where the current working block corresponds to a current working block. Similar restrictions may also be applied to slice/tile-based parallel processing.
摘要翻译：公开了使用限制参考区域的IntraBC编码方法。从可用的梯形参考区域中选择参考块，该梯形图参考区域包括当前CTU行中的当前工作块之前的先前处理的块以及一个或多个先前CTU行中的先前处理的块。与前一个CTU行相比，远离当前CTU行的一个CTU行的第二先前CTU行的最后一个先前处理的块的位置总是处于相同的垂直位置，或者在最后一次先前处理的相同垂直位置之后第一个CTU行的块。当前图片可以划分成多个CTU行，用于在多个CTU行上应用波前并行处理（WPP），其中当前工作块对应于当前工作块。类似的限制也可以应用于基于片/片的并行处理。

摘要： Several implementations relate, for example, to depth encoding and/or filtering for 3D video (3DV) coding formats. A sparse dyadic mode (308) for partitioning macroblocks (MBs) along edges in a depth map is provided as well as techniques for trilateral (or bilateral) filtering of depth maps that may include adaptive selection between filters sensitive to changes in video intensity and/or changes in depth. One implementation partitions a depth picture, and then refines the partitions based on a corresponding image picture. Another implementation filters a portion of a depth picture based on values for a range of pixels in the portion. For a given pixel in the portion that is being filtered, the filter weights a value of a particular pixel in the range by a weight that is based on one or more of location distance, depth difference, and image difference.
