Real-time encoding system of multiple spatially scaled video based on shared video coding information

摘要

In one embodiment, a method comprising receiving at a single encoding engine an input video stream having one or more pictures of a first size; and generating by the single encoding engine, in parallel, plural encoded streams, a first of the encoded streams comprising one or more pictures of the first size and a second of the encoded streams comprising one or more pictures of a second size that is smaller than the first size, the encoding of the second stream based on sharing video coding information used in encoding the first encoded stream.
