Abstract
Moving broadcast material in the compressed domain as data files with file transfer protocols can maintain image quality, reduce operating costs, and enhance operational capabilities. File formats have evolved over several years: some have been standardized, others are being held as proprietary technology, and new formats are being introduced. Digital Moving Picture Exchange, the first to be standardized by SMPTE, is used for uncompressed material transfers by telecine and synthetic image rendering systems. The next, General Exchange Format, is intended for news, sports, and on-air operations. The AAF Association has released an audio/video editing tools set designed for post-production and rich-editing applications. The Pro-MPEG Forum is working with SMPTE to develop a new file format, the Material Exchange Format, which will support a broad range of applications. Broadcasters must examine their requirements and choose a file or streaming format that has the features that meet their needs.
