摘要： In general, this disclosure describes techniques for exchanging information between a plurality of encoder modules and a multiplex module to combine segments of data from the encoder modules with an improved overall quality. In particular, the encoder modules associate their respective segments of data with quality and rate information and send at least the quality and rate information associated with the segments of data to the multiplex module. The multiplex module analyzes the quality and rate information to determine whether the segments of data that encoder modules desire to include in the current superframe fit within the available bandwidth of a transmission channel. If the multiplex module determines the plurality of segments of data do not fit within the available bandwidth, the multiplex module selects one or more of the segments to be resized based on the quality and rate information received from the encoder modules.

摘要： In general, this disclosure describes techniques for encoding and decoding sequences of video frames using fragmentary reference pictures. The disclosure presents video encoding and decoding techniques for modified temporal compression based on fragmented references rather than complete reference pictures. In a typical sequence of video frames, only a portion (i.e., a tile) of each frame includes moving objects. Moreover, in each frame, the moving objects tend to be confined to specific areas that are common among each frame in the sequence of video frames. As described herein, such common areas of motion are identified. Pictures are then extracted from the identified areas of the video frames. Because these pictures may represent only portions of the frames, this disclosure refers to these pictures as “fragments.” It is then these fragments that are used as reference pictures for generating predicted frames during a motion compensation process, rather than the entire frame.
摘要翻译： 通常，本公开描述了使用片段参考图片对视频帧的序列进行编码和解码的技术。 本公开提供了基于分段参考而不是完整参考图片的用于修改的时间压缩的视频编码和解码技术。 在典型的视频帧序列中，每个帧的仅一部分（即瓦片）包括运动对象。 此外，在每个帧中，移动对象倾向于被限制在视频帧序列中的每个帧中共同的特定区域。 如本文所述，识别这样的公共运动区域。 然后从视频帧的识别区域中提取图像。 因为这些图片可以仅表示帧的一部分，所以本公开将这些图片称为“片段”。 那么这些片段被用作用于在运动补偿过程期间生成预测帧而不是整个帧的参考图像。

摘要： This disclosure describes adaptive video encoding and decoding techniques for encoder-assisted frame rate up-conversion (EA-FRUC). An encoder selectively encodes at least a portion of a video frame, such as a block, using an interpolated FRUC frame as a reference. The encoder interpolates at least a portion of the FRUC frame at the same time instance as the yet to be encoded video frame, and selects one of a plurality of FRUC encoding modes for that portion, e.g., based on rate distortion (RD). The encoder encodes the frame using the selected FRUC encoding mode, the FRUC reference frame, and any additional reference frames that may be indicated. A decoder interpolates the FRUC frame and uses it or decoding with knowledge of the particular FRUC mode that was used by the encoder. The encoder communicates the FRUC mode for a block via one or more existing parameters in the encoded video frame.
