ABSTRACT:
A transcode architecture determines if a media source file needs to be transcoded for playback on a target playback device, and if so, the proper format needed for transcoding the source file. A transcode architecture includes a transcode manager, a transcode matrix, a transcode engine and a cache for storing transcoded media files. A media library stores media source files and device capabilities information. The transcode manager controls a transcode process in which the transcode matrix generates a profile for a media source file and accesses device capabilities that indicate playback capabilities for a target playback device. The transcode matrix compares parameters of the source profile with the device capabilities to decide whether the source file must be transcoded to enable playback of the file on the target playback device, and if so, the proper format needed for transcoding the source file.
