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. ## Claims ### Claim 1 A system for receiving media content comprising: a receiver communicatively coupled to a differential versioning decoder, the differential versioning decoder comprising a processor and a non-transitory computer-readable medium with computer readable instructions embedded thereon, wherein the computer readable instructions, when executed, cause the processor to: receive a first media file comprising a first set of data with a first set of attributes, the first set of attributes selected from one or more attribute classes; receive a first differential data file comprising a set of differential data, the set of differential data having been generated by comparing the first media file and a second media file with a second set of attributes; and generate a second media file by applying the first differential data file to the first media file. ### Claim 2 (depends on 1) The system of claim 1, wherein the computer readable instructions, when executed, further cause the processor to receive a metadata file comprising an encoding data set configured to enable the differential versioning decoder to generate the second media file. ### Claim 3 (depends on 1) The system of claim 1, further comprising a playback device communicatively coupled to the differential versioning decoder, the playback device configured to playback the second media file. ### Claim 4 (depends on 3) The system of claim 3, wherein the playback device is a television, a mobile phone, a tablet computer, a personal computer, a video game console, or a projector. ### Claim 5 (depends on 3) The system of claim 3, further comprising a communications network and a media repository, wherein the media repository is located on the communications network and the first media file and the first differential data file are stored in the media repository. ### Claim 6 (depends on 5) The system of claim 5, further comprising a local gateway configured to establish a communications channel between the playback device and the communications network, wherein the playback device is coupled to a private network segment of the local gateway. ### Claim 7 (depends on 6) The system of claim 6, wherein the differential versioning decoder is located on the communications network. ### Claim 8 (depends on 6) The system of claim 6, wherein the differential versioning decoder is located on the private network segment of the local gateway. ### Claim 9 (depends on 1) The system of claim 1, wherein each attribute class is selected from the group consisting of a number of bits, a bit-depth, a color format, an audio format, a localization format, and a content format. ### Claim 10 (depends on 9) The system of claim 9, wherein the second set of attributes is a subset of the first set of attributes. ### Claim 11 (depends on 9) The system of claim 9, wherein the first set of attributes is a subset of the second set of attributes. ### Claim 12 (depends on 2) The system of claim 2, wherein the metadata file further comprises a checksum value corresponding to the second media file. ### Claim 13 A system for receiving media content comprising: a receiver communicatively coupled to a differential versioning decoder, the differential versioning decoder comprising a processor and a non-transitory computer-readable medium with computer readable instructions embedded thereon, wherein the computer readable instructions, when executed, cause the processor to: receive a first media file comprising a first set of data with a first set of attributes, the first set of attributes selected from one or more attribute classes; receive a first differential data file comprising a set of differential data, the set of differential data having been generated by comparing the first media file and a second media file with a second set of attributes; generate a second media file by applying the first differential data file to the first media file; and receive a metadata file comprising an encoding data set configured to enable the differential versioning decoder to generate the second media file. ### Claim 14 (depends on 13) The system of claim 13, further comprising a playback device communicatively coupled to the differential versioning decoder, the playback device configured to playback the second media file. ### Claim 15 (depends on 14) The system of claim 14, wherein the playback device is a television, a mobile phone, a tablet computer, a personal computer, a video game console, or a projector. ### Claim 16 (depends on 14) The system of claim 14, further comprising a communications network and a media repository, wherein the media repository is located on the communications network and the first media file and the first differential data file are stored in the media repository. ### Claim 17 (depends on 13) The system of claim 13, wherein each attribute class is selected from the group consisting of a number of bits, a bit-depth, a color format, an audio format, a localization format, and a content format. ### Claim 18 (depends on 17) The system of claim 17, wherein the second set of attributes is a subset of the first set of attributes. ### Claim 19 (depends on 17) The system of claim 17, wherein the first set of attributes is a subset of the second set of attributes. ### Claim 20 (depends on 13) The system of claim 13, wherein the metadata file further comprises a checksum value corresponding to the second media file.
