Abstract
There is provided a system and method for quality assured media file storage. There is provided a method for use by a processor to verify quality of a new media file by transcoding a master media file into a first media file, determining a quality of the first media file, applying a first quality assurance scheme to the first media file for an assured quality, calculating a first hash value using a hash function for the first media file, storing the first hash value in a memory, transcoding the master media file into a new media file, calculating a test hash value using the hash function for the new media file, and searching the memory for the test hash value to decide whether the new media file has the assured quality, without having to apply the first quality assurance scheme again to the new media file.
