摘要: The present invention provides methods and systems that create numerous high-quality output streams at different spatial or temporal resolutions from a single input stream. An input stream is transcoded at a first transcoder module to provide N output streams, wherein each of the N output streams comprises different versions of the input stream. Parameters are obtained during transcoding of the input stream and provided to a second transcoder module together with the input stream. The input stream may be transcoded at the second transcoder module to produce M output streams based on the parameters received from the first transcoder module. The parameters received from the first transcoder module may be used to enhance the transcoding at the second transcoder module.
