More than ten years after the launch of its massive preservation and digitization plan, and after several months of studies and experimentation, Ina, Institut National de l'Audiovisuel-France, has opted for JPEG 2000 as the master file format for its professional television archives. This strategic decision will cause the institute to convert its technical system for managing digital archives and to migrate several hundred thousand hours of TV program masters currently stored on Digital Betacam. This will have a huge impact. Ina, which currently has 800,000 hr of digitized archives, will put the first JPEG 2000 transfer lines into service by the end of 2011. It will take three years to convert the entire technical system to JPEG 2000, and another four to six years to complete the migration of the programs stored on digital beta. During this transitional period, the current and future formats will co-exist. The following paper explains the reasons and methodology that led to this choice and the way it is being implemented.
