Abstract: A system and method provides transcoding a video in parallel by multiple transcoders based on a measure of video coding complexity (VCC). The system has a video pre-processing module, a master transcoder, a transcoding controller and multiple transcoders. The video pre-processing module transcodes a source video into an intermediate video. The master transcoder partitions the intermediate video into multiple transcoding units, where a transcoding unit identifies a portion of data of the intermediate video for transcoding. The master transcoder further generates a transcoding request for each transcoding unit. The transcoding controller distributes the transcoding units to the multiple transcoders, which transcode the data of the transcoding units in parallel into transcoded data.

Abstract translation: 基于视频编码复杂度（VCC）的测量，系统和方法通过多个代码转换器并行地对视频进行代码转换。 该系统具有视频预处理模块，主代码转换器，代码转换控制器和多个代码转换器。 视频预处理模块将源视频转码为中间视频。 主代码转换器将中间视频分割成多个代码转换单元，其中代码转换单元识别用于代码转换的中间视频的一部分数据。 主代码转换器还为每个代码转换单元生成代码转换请求。 代码转换控制器将代码转换单元分配给多个代码转换器，其将代码转换单元的数据并行转码为代码转换数据
