摘要： An Encoder Assisted Frame Rate Up Conversion (EA-FRUC) system that utilizes video coding and pre-processing operations at the video encoder to exploit the FRUC processing that will occur in the decoder in order to improve compression efficiency and reconstructed video quality is disclosed. One operation of the EA-FRUC system involves determining whether to encode a frame in a sequence of frames of a video content by determining a spatial activity in a frame of the sequence of frames; determining a temporal activity in the frame; determining a spatio-temporal activity in the frame based on the determined spatial activity and the determined temporal activity; determining a level of a redundancy in the source frame based on at least one of the determined spatial activity, the determined temporal activity, and the determined spatio-temporal activity; and, encoding the non-redundant information in the frame if the determined redundancy is within predetermined thresholds.

摘要： This disclosure describes techniques for video coding rate adaptation to reduce packetization overhead. The video coding rate controls the number of coding bits allocated to a segment of encoded video, and hence the length of the encoded video segment. Differences between the length of the encoded video segment and the cumulative length of a series of packets used to encode the video segment result in unused packet space within the last packet in the series. This unused packet space is typically filled with padding bits. In accordance with the disclosure, the video coding rate is adjusted for a segment of digital video so that the encoded video more closely fits within the series of packets, thereby reducing the number of padding bits required by the last packet.
摘要翻译：本公开描述了用于视频编码速率适配以减少分组化开销的技术。视频编码率控制分配给编码视频片段的编码比特数，并因此控制编码视频片段的长度。编码视频段的长度与用于编码视频段的一系列分组的累积长度之间的差异导致该系列中最后一个分组内未使用的分组空间。这个未使用的分组空间通常用填充比特填充。根据本公开，对于数字视频段调整视频编码率，使得编码视频更接近于一系列分组，从而减少最后一个分组所需的填充比特数。

摘要： In general, this disclosure is directed to decoding techniques for interpolating video frames. In particular, the techniques of this disclosure may be used to dynamically adjust a frame interpolation operation based on analysis of information associated with one or more video frames. In response to the analysis of the information associated with one or more frames, the interpolation control module adjusts the frame interpolation operation in number of different manners. For example, the interpolation control module may dynamically enable or disable motion compensated frame interpolation, select a different type of interpolation, select a video frame prediction mode to be used in the motion compensated frame interpolation, or select different threshold values for frame interpolation.
