Abstract
A method includes separating, using a separation component, a plurality of input streams into a plurality of audio streams having different bitrates and a plurality of video streams having different bitrates; transcoding, using an audio transcoder, the plurality of audio streams into a plurality of transcoded audio streams having different transcode qualities; transcoding, using a video transcoder, the plurality of video streams into a plurality of transcoded video streams having different transcode qualities; segmenting, using a segmentation component, the plurality of audio streams into a plurality of equivalent audio segments based on identified segment boundaries associated with the plurality transcoded audio streams and the plurality of video streams into a plurality of equivalent video segments based on identified segment boundaries associated with the plurality of transcoded video streams; and joining, using a conjoining component, the plurality of equivalent audio segments and the plurality of video segments into a single stream.
