    Abstract: Systems and techniques are described herein for generating and/or processing virtual content in a distributed system (e.g., a distributed extended reality system). For example, a first device (e.g., a client device) of a distributed extended reality system may transmit one or more sets of pose prediction parameters (e.g., prediction coefficients, prediction time associated with raw pose data, and/or the raw pose data) to a second device (e.g., a server device) of the distributed extended reality system. The second device may predict one or more poses of the second device based on the set(s) of pose prediction parameters, and may generate virtual content based on a pose of the predicted pose(s) of the first device. The second may transmit and the first device may receive the virtual content. The first device may then display one or more virtual objects based at least in part on the received virtual content.

    Abstract: Graphics processing in a client device includes receiving, as part of a vector streaming split rendering process, a bit stream encoding a sequence of shading atlases of the process. Each shading atlas includes blocks. The client decodes a particular shading atlas of the sequence of shading atlases, and determines that a particular block of the particular shading atlas was unsuccessfully decoded. The client identifies a stored block of a prior shading atlas of the sequence of shading atlases as a successfully decoded earlier version of the particular block. The client renders the particular shading atlas using the stored block instead of the particular block.

    Abstract: The techniques of this disclosure relate to video encoding and include using an inter mode determination for neighboring blocks, rather than the final prediction mode determination for the neighboring block, when determining an inter mode for a current block. In this way, inter mode and intra mode estimation may be separated and performed in different stages of a multi-threaded parallel video encoding implementation. In addition, this disclosure also proposes generating sub-pixel values in a third stage of the multi-threaded parallel video encoding implementation at a frame level, rather than for each macroblock during inter mode estimation process for that macroblock.

    Abstract translation: 本公开的技术涉及视频编码，并且包括当确定当前块的帧间模式时，使用相邻块的帧间模式确定而不是相邻块的最终预测模式确定。 以这种方式，可以在多线程并行视频编码实现的不同阶段中分离和执行帧间模式和帧内模式估计。 此外，本公开还提出了在帧级别的多线程并行视频编码实现的第三级中生成子像素值，而不是在针对该宏块的帧间模式估计处理期间为每个宏块生成子像素值。
