SMPTE ST 2021-2:2015

Generally, the Broadcast eXchange Format (BXF) defines the format and content of XML Messages for the interchange of data and metadata among professional systems, as follows:

1. Broadcast schedules, including playout and record schedules
2. As run information
3. Content metadata, such as Content ID, Title, Duration, etc.
4. Content management requests such as dub and purge requests
5. Requests for transfer of content some of which will result in the transfer of Content essence between professional systems.
6. Ports as used by TCP/IP for the exchange of messages

The primary systems envisioned as users of this standard are:

• Program Management Systems
• Broadcast Traffic Systems
• Master Control Automation Systems
• Content Distribution Systems

This particular document is focused on Protocol-related topics as they relate to BXF. The main BXF document (SMPTE ST 2021-1) should be read first, and this part (SMPTE ST 2021-2) should be considered as a companion to SMPTE ST 2021-1 for those interested in all things Protocol.
