Abstract:
1. A method comprising: generating, using a plurality of encoders, a plurality of separately transrated output bitstreams from a compressed input bitstream including at least one input video segment; and incorporating the plurality of output bitstreams into a video block for the compressed input bitstream comprising a header, an input video segment, a plurality of output video segments corresponding to the plurality of output bitstreams, and offset information for each ones of the plurality of output video segments, the offset information configured to indicate a start of a corresponding output video segment responsive to ones of the plurality of output video segments packaged end-to-end within the video block, and separately encoding individual ones of the output video segments at a different bit rate while including a same portion of programming content from the compressed input bitstream; wherein the offset information allows for selection of at least one output video segment from the plurality of output video segments responsive to bitrate demands of other concurrent output streams from at least one other compressed input bitstream without real-time transrating of any of the plurality of the output bitstreams.
