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:
Broadcast schedules, including playout and record schedules
As run information
Content metadata, such as Content ID, Title, Duration, etc.
Content management requests such as dub and purge requests
Requests for transfer of content some of which will result in the transfer of Content essence between professional systems.
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.
