Broadcast Exchange Format (BXF) - Protocol (Revision of SMPTE ST 2021-2:2009). 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 (ST 2021-1) should be read first, and this part (ST 2021-2) should be considered as a companion to ST 2021-1 for those interested in all things Protocol.
