Abstract
A method, system, and computer program product for converting an Extensible MPEG-4 Textual (XMT) document into a binary MPEG-4 (mp4) file. The XMT document may comprise of zero or more associated media data files. The invention includes generating an intermediate document representing the mp4 file and creating the mp4 file based on the intermediate document and the associated media data files. A first converter is configured to input the XMT document and to generate at least one intermediate document representing the structure of the mp4 file. A second converter is configured to input the intermediate document and any associated media files and to generate the mp4 file.
Claims32
A method for converting an Extensible MPEG-4 Textual (XMT) document into a binary MPEG-4 (mp4) file, the XMT document having zero or more associated media data files, the method comprising:
- generating an intermediate document representing the mp4 file;
- and
- creating the mp4 file based on the intermediate document and the associated media data files.
A system for converting an Extensible MPEG-4 Textual (XMT) document into a binary MPEG-4 (mp4) file, the XMT document having zero or more associated media files, the system comprising:
- a first converter configured to input the XMT document and to generate at least one intermediate document representing the structure of the mp4 file;
- and
- a second converter configured to input the intermediate document and any associated media files, the second converter further configured to generate the mp4 file.
A computer program product embodied in a tangible media comprising:
- computer readable program codes coupled to the tangible media for converting an Extensible MPEG-4 Textual (XMT) document into a binary MPEG-4 (mp4) file, the XMT document having zero or more associated media data files, the computer readable program codes configured to cause the program to:
- generate an intermediate document representing the mp4 file;
- and
- create the mp4 file based on the intermediate document and the associated media data files.
