Abstract: An aspect of the disclosure is directed to transmitting a reduced stream of encoded video frames. An original stream of encoded video frames is analyzed, a plurality of frames are removed without re-encoding encoded video frames to generate the reduced stream of encoded video frames, and the reduced stream and metadata describing the plurality of removed frames are transmitted. An aspect of the disclosure is directed to creating a new version of an original stream of encoded video frames from a reduced stream of encoded video frames. The reduced stream of encoded video frames is received, the plurality of removed frames is identified based on metadata related to the reduced stream, a plurality of replacement frames are generated, and the plurality of replacement frames are added to the reduced stream of encoded video frames to recreate the new version of the original stream of encoded video frames.

Abstract translation: 本公开的一个方面涉及发送缩减的编码视频帧流。 分析编码视频帧的原始流，移除多个帧，而不对编码视频帧进行重新编码，以产生经缩减的编码视频帧流，并且传输描述多个移除帧的简化流和元数据。 本公开的一个方面涉及从编码视频帧的缩减流创建编码视频帧的原始流的新版本。 接收编码视频帧的缩减流，基于与减少流相关的元数据来识别多个被去除的帧，生成多个替换帧，并且将多个替换帧添加到编码视频帧的缩减流中 以重新创建新版本的原始编码视频帧流。
