White Paper WHP 241 Download
The BBC Archive now contains around 15 Petabytes (and growing) of uncompressed files that have been created from videotapes using the BBC R&D Ingex Archive software. The files conform to a custom profile of the sophisticated media file wrapper standard known as Material eXchange Format (MXF). The details of the custom profile are fully specified by other BBC R&D White Papers but these documents are not suitable for newcomers to MXF. This White Paper provides an overview of the BBC Archive MXF profile along with a brief introduction to the MXF fundamentals that are required in order to understand it. A diagram of the physical structure of the MXF files is presented - this form of visualisation is found to be very helpful in considering new means of processing the files as well as understanding the consequences of different modes of file corruption.
