What the Industry Learned from GXF and How it can Help Everyone

Bob Edge

In 1997 Grass Valley developed the General eXchange Format (GXF) for professional TV archives and to facilitate transfer of compressed video files over data networks. This file format is in use in hundreds of facilities around the world. In 1999, the Pro-MPEG Forum started work on the Material eXchange Format (MXF) as a flexible “container” format that could be adapted to a wide variety of applications while transporting a variety of audio, video, and data essence types. In addition, MXF was designed to incorporate a rich set of metadata. After the initial development was completed by the Pro-MPEG Forum, the work was contributed to SMPTE for standardization. The resulting standards are now supported by many broadcast equipment vendors. A lot was learned from the GXF experience. Some of this knowledge improved MXF, while other ideas can help end users who are starting to deploy MXF-based systems.
