Abstract
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.
