Abstract

A method for transcoding an input stream to a desired output format using a transcoder framework. In response to a given transcoder of the framework recognizing an external reference that it cannot transcode, the method calls a subseries of specialized transcoders to transcode the external reference. After the subseries of specialized transcoders generates a transcoded external reference, that reference is returned back to the given transcoder, where it is incorporated into the transcoder's output. Transcoder sub-chains are used in this manner as modular, building blocks in the transcoder framework.
