摘要： Disclosed herein are exemplary embodiments of innovations in the area of encoding pictures or portions of pictures and determining whether and how certain encoding operations should be performed and flagged for performance by the decoder in the bitstream. In particular examples, various implementations for selectively encoding picture portions ( e.g. , blocks) in a skip mode ( e.g. , as in the skip mode of the H.265/HEVC standard) are disclosed. Embodiments of the disclosed techniques can be used to improve encoder efficiency, decrease overall encoder resource usage, and/or improve encoder speed. Such embodiments can be used in encoder modes in which efficient, fast encoder performance is desired (e.g., during encoding of live events, such as video conferencing).

摘要： The computational complexity of video encoding is reduced by selectively skipping certain evaluation stages when deciding whether to use inter-picture prediction or intra-picture prediction for a unit of a picture. For example, a video encoder receives a current picture of a video sequence and encodes the current picture. As part of the encoding, for a current unit (e.g., coding unit, macroblock) of the current picture, the encoder can skip time-consuming evaluation of intra-picture prediction modes for blocks of the current unit in situations in which motion compensation for the current unit is already expected to provide effective rate-distortion performance, and use of intra-picture prediction is unlikely to improve performance. In particular, evaluation of the intra-picture prediction modes for blocks of the current unit can be skipped when the current unit has little or no movement and intra-picture prediction has not been promising for the collocated unit in the previous picture.
摘要翻译：当决定是否对图像的单位使用帧间预测或图像内预测时，通过有选择地跳过某些评估阶段来减少视频编码的计算复杂度。例如，视频编码器接收视频序列的当前画面并对当前画面进行编码。作为编码的一部分，对于当前图像的当前单元（例如，编码单元，宏块），编码器可以跳过对当前单元的块的图像内预测模式的耗时评估，目前的单元已经预计将提供有效的失真性能，并且图像内预测的使用不太可能提高性能。特别地，当当前单元很少或没有移动时，可以跳过对当前单元的块的图像内预测模式的评估，并且对于前一图像中的并置单元，图像内预测尚未有希望。

摘要： An input of an encoder receives moving image data comprising a sequence of frames to be encoded, each frame comprising a plurality of blocks in two dimensions with each block comprising a plurality of pixels in those two dimensions. A motion prediction module performs encoding by, for at least part of each of a plurality of said frames, coding each block relative to a respective reference portion of another frame of the sequence, with the respective reference portion being offset from the block by a respective motion vector. According to the present disclosure, the moving image data of this plurality of frames comprises a screen capture stream, and the motion prediction module is configured to restrict each of the motion vectors of the screen capture stream to an integer number of pixels in at least one of said dimensions.

摘要： Multiple data streams are transmitted from a transmitting device via an end-to-end or process-to-process channel to a receiving device. At the transmitting device a media data stream is generated. A maximum packet size for another data stream is determined based on a determined end-to-end or process-to-process bandwidth and using playout information pertaining to the media data, which conveys a desired playout rate of the media data. At the transmitting device, based on the determined maximum packet size, a plurality of data packets of the other data stream is generated, each having a packet size no more than the determined maximum. The media and other data streams are multiplexed onto the channel at the transmitting device, thereby transmitting both of the data streams from the transmitting device to the receiving device via the same channel.
