Abstract
A method for delivering media content over a network includes transcoding the media content to generate multiple copies of the media content, each of the multiple copies having a different destination type or a different source type or both, storing the multiple copies in a cache, receiving requests for the media content, and selecting and delivering a copy of one of the multiple copies in response to each of the requests. A further method for providing media content transcoding services includes fetching media content, selecting one of multiple transcoders for transcoding from multiple source types to multiple destination types, wherein the one transcoder is selected based at least on the destination type, sending the media content to the selected transcoder, transcoding the media content to the destination type, thereby generating transcoded media content, and transmitting the transcoded media content.
