    • Various embodiments are directed to techniques for dividing compressed video data into portions for load balancing or redundancy among multiple video transcoders. A device includes an analysis component to analyze NAL units of compressed video data representing a motion video to identify a GOP refresh, and to compare a period of time represented by frames of the motion video following the GOP refresh to a maximum; a division component to divide the compressed video data at a first point coincident with the GOP refresh to define a start of a compressed video portion, and at a second point to define an end of the compressed video portion to include frames of the motion video representing a shorter period of time between the first and second points than the maximum; and an assignment component to assign the compressed video portion to a transcoding device. Other embodiments are described and claimed.
    • 各种实施例涉及将压缩视频数据分割成用于多个视频代码转换器之间的负载平衡或冗余的部分的技术。 一种装置包括分析部件,用于分析表示运动视频的压缩视频数据的NAL单元以识别GOP刷新,并将由GOP刷新之后的运动视频的帧表示的时间段与最大值进行比较; 分割部件,用于在与GOP刷新一致的第一点处分割压缩视频数据以定义压缩视频部分的开始,并且在第二点定义压缩视频部分的结束,以包括表示 第一点和第二点之间的时间比最大值更短; 以及分配部件,用于将压缩视频部分分配给代码转换装置。 描述和要求保护其他实施例。
