Abstract
Systems for electronic media distribution includes a differential versioning server configured to receive a first media file including a first set of data with a first set of attributes and a second media file including a second set of data with a second set of attributes, generate a first differential data file as a function of differences between the first media file and the second media file, and generate a first differential metadata file including an encoding data set configured to enable a media decoder to regenerate the second media file by applying the first differential data file to the first media file. Systems for electronic media distribution may also include a receiver communicatively coupled to a differential versioning decoder configured to receive the first media file and the first differential data file and generate the second media file by applying the first differential data file to the first media file.
