摘要： Innovations in intra block copy (“BC”) prediction mode facilitate intra BC prediction that is more effective in terms of rate-distortion performance and/or computational efficiency of encoding and decoding. For example, some of the innovations provide ways to select block vector (“BV”) values more effectively. Other innovations provide ways to encode/decode BV values more efficiently. Still other innovations address how to perform in-loop deblock filtering when a block has intra BC prediction mode, or address how to perform intra BC prediction when constrained intra prediction is enabled.

摘要： Techniques and tools for reducing latency in video encoding and decoding by constraining latency due to reordering of video frames, and by indicating the constraint on frame reordering latency with one or more syntax elements that accompany encoded data for the video frames. For example, a real-time communication tool with a video encoder sets a syntax element that indicates a constraint on frame reordering latency, which is consistent with inter-frame dependencies between multiple frames of a video sequence, then outputs the syntax element. A corresponding real-time communication tool with a video decoder receives the syntax element that indicates the constraint on frame reordering latency, determines the constraint on frame reordering latency based on the syntax element, and uses the constraint on frame reordering latency to determine when a reconstructed frame is ready for output (in terms of output order).
摘要翻译：技术和工具，用于通过限制由于视频帧的重新排序而引起的等待时间，以及通过与伴随视频帧的编码数据的一个或多个语法元素指示对帧重排序延迟的约束来减少视频编码和解码中的延迟。例如，具有视频编码器的实时通信工具设置指示对帧重新排序等待时间的约束的语法元素，其与视频序列的多个帧之间的帧间依赖性一致，然后输出语法元素。具有视频解码器的对应的实时通信工具接收指示对帧重新排序等待时间的约束的语法元素，基于语法元素确定对帧重新排序等待时间的约束，并且使用对帧重排序等待时间的约束来确定何时重构帧准备输出（按照输出顺序）。

摘要： Rules for the signaling and interpretation of chroma position are described. One rule, called the short rule, defines fifteen discrete chroma centering positions and corresponding four-bit syntax element. Another rule, called the extended rule, defines 81 discrete chroma centering positions and corresponding seven-bit syntax elements. A described method includes receiving digital media data at a digital media encoder, determining chroma position information for the received digital media data, and representing the chroma position information with one or more syntax elements in an encoded bitstream. The one or more syntax elements are operable to communicate the chroma position information to a digital media decoder. The chroma position information facilitates an image rotation or flip.

摘要： A first frame of data is encoded and a first timestamp associated with the first frame of data is generated. The first timestamp includes complete timing information. The first frame of data and the associated first timestamp is transmitted to a destination. A second frame of data is encoded and a second timestamp associated with the second frame of data is generated. The second timestamp includes a portion of the complete timing information. The second frame of data and the associated second timestamp is then transmitted to the destination. Additional frames of data are encoded and additional timestamps associated with the additional frames of data are generated. The majority of the additional timestamps include a portion of the complete timing information.

摘要： A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

摘要： According to the principles of the invention, there is provided a system, apparatus, and method for managing media in a multimedia conferencing system according to media roles. Each media stream may be explicitly labeled with a role that describes the function or purpose of the stream, such as “people” or “content.” The labels may be hierarchical, and may include layers for media type, additional media source description, and the like, e.g., “people/presenter” or “people/presenter/video.” A policy manager is provided for managing roles, such that the multimedia conference may be more effectively presented to participants. A token management system may also be provided so that control of the multimedia conference roles can be transferred during the conference.
