Patent ID: 7669121

Claim:
A system comprising: one or more processors; a media source file; device capabilities from a target playback device; and a transcode matrix accessible to the one or more processors and configured to: generate a source profile from the media source file; determine that the target device can support the media source file based on a comparison of the source profile with the device capabilities, wherein the transcode matrix determines that the target device supports the media source file by determining that a total bitrate restriction is specified for an audio bitrate and a video bitrate of one or more device profiles of the target playback device and by selecting a particular device profile with a lowest audio bitrate above a certain threshold when a total of the audio bitrate and the video bitrate of the media source file is above the total bitrate restriction of each of the one or more device profiles; determine that the media source file needs to be transcoded based on a user-preferred bitrate of a particular parameter; and transcode the media source file according to a maximum bitrate of the particular parameter supported by the target device as indicated by the device capabilities when the target device does not support the user-preferred bitrate of the particular parameter.
