Abstract: A system apparatus and method for concurrent delivery of a plurality of video streams comprising one or more transcoders for bitrate reduction and a cache memory to save copies of transcoded segments. When the total outgoing bitrate of the system exceeds a predefined threshold, the system decides which of the video segments to transcode and the magnitude of bitrate reduction. Before assigning a transcoder for the bitrate reduction, the system first checks the cache for saved transcoded segments. If appropriate transcoded segments are not found in cache, the system may assign a transcoder for the video segments designated for bitrate reduction.
