SMPTE Publishes Landmark SMPTE-2021 (BXF) Standard

Standardizes the Communication of Three Types of Data Exchange

The Society of Motion Picture and Television Engineers is pleased to announce the publication of a landmark standard, SMPTE-2021 (BXF). This standard is the end product of a three-year effort on the part of over 150 people, representing users, vendors, and other interested parties from around the world.

BXF (Broadcast eXchange Format) standardizes the communication of three basic types of data exchange:

1. Schedule and as run information
2. Content metadata
3. Content movement instructions

SMPTE's S22-10 Working Group, chaired by Chris Lennon of Harris Corporation, is responsible for the creation of BXF. The working group has enjoyed the active participation of representatives of over 70 organizations. SMPTE-2021 is expected to replace hundreds of proprietary batch and file-oriented interfaces currently in use.

BXF provides many advantages to users, among them:

- A single method of exchanging data among systems such as Program Management, Traffic, Automation, and Content Distribution
- Support for file and message based (dynamic) data exchange
- Increased integration of related systems
- Extended metadata set for data exchange

It is expected that systems employing the BXF standard for communications will offer users dramatic workflow benefits, including quantifiable cost savings, and potential for easy support of new revenue streams.

In addition, efforts are currently underway to continue the excellent momentum around BXF with an effort to develop a Recommended Practice for BXF deployments and to start assessment of current implementations that would identify possible enhanced features that may be incorporated in the future.
Organizations or individuals having interest in these efforts are encouraged to join in this work.

Several vendors are expected to showcase products employing BXF at NAB2008. To obtain a copy of SMPTE-2021, please go to .
