Description: 

D10SumChecker is intended for ensuring the integrity of MXF D10 Files. File integrity verified through the computation of a checksum for the whole file is a weak strategy in the case of the large 30GB/hour MXF/D10 files. An error limited to a single bit would give a checksum failure  and trigger a recovery process from a backup copy for quite a large amount of data. In addition, if the second copy is found corrupted the file might be declared “lost”. This tool supports an integrity check based on data units which match content usable elements (“edit units”), such as video frames. Applications/benefits:

  • files with errors are still partially usable
  • errors are located and you know exactly which parts are not affected
  • your recovery process might work only on the damaged parts
  • from two broken copies you still have a chance of recovery
  • you can track and locate content modifications.

This tool has been developed under the EU-funded project PrestoPRIME.
