A collection of well-formed, but possibly semantically invalid, binary encoded multimedia data components or packages as well as the binary encoded announcement, signaling, and interchange protocols used in their transmission are converted into one or more well-formed extensible markup language (XML) files. Such XML files may then be validated according to one or more pre-defined XML schemas, or similar schema languages, in order to verify that the data and protocol structures and substructures adhere to prior defined semantic constraints.

1. A method comprising: generating, by a computing device and based on first encoded video, first markup language content, wherein the first encoded video comprises video data that is formatted according to a version of a protocol or a version of a multimedia format;validating, according to a first schema, the first markup language content, wherein validating the first markup language content results in validated first content that adheres to one or more constraints of the version of the protocol or the version of the multimedia format;generating, based on the validated first content, a second schema;generating, based on second encoded video, second markup language content;validating, according to the second schema, the second markup language content; andtransmitting, to one or more devices, the second encoded video. 2. The method of claim 1, wherein the first markup language content comprises first extensible markup language (XML) content. 3. The method of claim 1, wherein validating the first markup language content comprises validating that a data value of the video data is within a data value range. 4. The method of claim 1, wherein the one or more constraints comprise a co-occurrence constraint of the version of the protocol or the version of the multimedia format, and wherein validating the first markup language content comprises validating, according to the co-occurrence constraint, the first markup language by at least: determining a first data value of the first encoded video, andvalidating, according to the first data value, that a second data value of the first encoded video is an acceptable value. 5. The method of claim 1, wherein the first schema comprises a RELAX NG schema. 6. The method of claim 1, wherein the version of the protocol or the version of the multimedia format comprises a version of an enhanced television binary interchange format (EBIF). 7. The method of claim 1, wherein the version of the protocol or the version of the multimedia format comprises a version of Motion Pictures Expert Group (MPEG). 8. The method of claim 1, wherein the version of the protocol or the version of the multimedia format comprises a version of Digital Video Broadcasting (DVB). 9. The method of claim 1, wherein the version of the protocol or the version of the multimedia format is associated with OPENCABLE. 10. A method comprising: generating, by a computing device and based on first encoded video, first markup language content, wherein the first encoded video comprises video data that is formatted according to a version of a protocol or a version of a multimedia format;validating, according to one or more constraints of the version of the protocol or the version of the multimedia format on the video data, the first markup language content, wherein validating the first markup language content results in validated content that adheres to the one or more constraints;generating, based on second encoded video, second markup language content;validating, based on the validated content, the second markup language content; andtransmitting, to one or more devices, the second encoded video. 11. The method of claim 10, wherein the first markup language content comprises first extensible markup language (XML) content. 12. The method of claim 10, wherein the one or more constraints comprise a constraint on a data value range for the version of the protocol or the version of the multimedia format. 13. The method of claim 10, wherein the one or more constraints comprise a co-occurrence constraint of the version of the protocol or the version of the multimedia format, and wherein validating the first markup language content comprises validating, according to the co-occurrence constraint, the first markup language by at least: determining a first data value of the first encoded video, andvalidating, according to the first data value, that a second data value of the first encoded video is an acceptable value. 14. The method of claim 10, wherein the version of the protocol or the version of the multimedia format comprises a version of an enhanced television binary interchange format (EBIF). 15. The method of claim 10, wherein the version of the protocol or the version of the multimedia format comprises a version of Motion Pictures Expert Group (MPEG), a version of Digital Video Broadcasting (DVB), or is associated with OPENCABLE. 16. An apparatus comprising: one or more processors; andmemory storing executable instructions that, when executed by the one or more processors, cause the apparatus to: generate, based on first encoded video, first markup language content, wherein the first encoded video comprises video data that is formatted according to a version of a protocol or a version of a multimedia format;validate, according to a first schema, the first markup language content, wherein causing the apparatus to validate the first markup language content results in validated first content that adheres to one or more constraints of the version of the protocol or the version of the multimedia format;generate, based on the validated first content, a second schema;generate, based on second encoded video, second markup language content;validate, according to the second schema, the second markup language content; andtransmit, to one or more devices, the second encoded video. 17. The apparatus of claim 16, wherein the first markup language content comprises first extensible markup language (XML) content. 18. The apparatus of claim 16, wherein the one or more constraints comprise a data value constraint that defines an acceptable data value range for the video data. 19. The apparatus of claim 16, wherein the one or more constraints comprise a co-occurrence constraint of the version of the protocol or the version of the multimedia format. 20. The apparatus of claim 16, wherein the version of the protocol or the version of the multimedia format comprises a version of an enhanced television binary interchange format (EBIF), a version of Motion Pictures Expert Group (MPEG), a version of Digital Video Broadcasting (DVB), or is associated with OPENCABLE.
