摘要： Media content coded using scalable coding techniques may be cached among a group of cache devices. Layered segments of the media content may be pre-loaded onto the cache devices, which may be located throughout a content distribution network, including a home network. The caching location of the media content may be determined based on multiple factors including a content preference associated with the group of cache devices and device capabilities. A cache controller may manage the caching of the media content.

摘要： Visual information may be delivered to streaming-capable devices in a viewing environment, such as a home environment or a commercial environment. The visual information can be adapted to user behavior and/or viewing conditions in such a way as to deliver a satisfactory user experience while conserving network resources, such as bandwidth and/or capacity. Viewing distance and/or ambient light, which may affect viewing conditions in a viewing environment, may be estimated. Bandwidth may be reduced by eliminating details that may not be perceived by the user in the estimated viewing conditions (e.g., by determining a spatial resolution (e.g. a maximum spatial resolution) perceptible under the viewing conditions and not exceeding that spatial resolution).

摘要： Sketch copy mode may be used to code blocks comprising irregular lines, syntax redundancy may be removed from blocks with special characteristics, and/or run value coding may be simplified. The parsing dependencies in palette coding design may be removed. For example, the context modeling dependency of the syntax element palette_transpose_flag may be removed, for example, by simplifying the corresponding context model. The context modeling of the syntax element palette_mode may be removed, for example, by using run-length coding without using context. The syntax parsing dependencies and/or the syntax signaling dependencies that are related with escape color signaling may be removed. A palette table generation process may handle input screen content video with high bit depths, for example, at the encoder side.
摘要翻译：草图复制模式可用于对包含不规则行的块进行编码，可从具有特殊特征的块中去除语法冗余，和/或可简化运行值编码。调色板编码设计中的解析依赖关系可能会被删除。例如，语法元素palette_transpose_flag的上下文建模依赖性可以例如通过简化相应的上下文模型而被移除。例如，可以通过使用游程长度编码而不使用上下文来移除语法元素palette_mode的上下文建模。可以移除与逃逸颜色信令相关的语法解析依赖性和/或语法信令依赖性。例如，在编码器侧，调色板表生成过程可以处理具有高位深度的输入屏幕内容视频。

摘要： Methods, apparatus, and systems for video coding/decoding are disclosed. One representative method includes a decoder receiving video content including at least a base layer (BL), an enhancement layer (EL) and phase information. The phase information includes an indicator indicating one or more sets of phase parameters from among plural sets of phase parameters. The method further includes assembling the BL into an inter-layer reference (ILR) picture based on the video content and the received phase information, selecting one or both of the ILR picture or an EL reference picture, and predicting a current EL picture using the phase information and one or more of the selected ILR picture or the selected EL reference picture.

摘要： A packet loss notification in a video transmission may be performed by a network device. The network device may receive a first video packet sent from a first client to a second client. The network device may determine that the first video packet has been lost. The network device may determine a video packet receiving port number of the first client. The network device may receive a second video packet sent from the second client to the first client. The network device may determine that the second video packet includes a destination port number that matches a video packet receiving port number of the first client. The network device may modify the second video packet by adding packet loss information indicating that the first video packet has been lost. The network device may send the modified second video packet to the first client.

摘要： A video coding system may perform inter-layer processing by simultaneously performing inverse tone mapping and color gamut conversion scalability processes on a base layer of a video signal. The video coding system may then perform upsampling on the processed base layer. The processed base layer may be used to code an enhancement layer. Bit depth may be considered for color gamut conversion modules. Luma and/or chroma bit depths may be aligned with respective larger or smaller bit depth values of luma and/or chroma.
