SMPTE Approves ST 2110 Standards for Professional Media Over Managed IP Networks
SMPTE announces the approval of the first standards within SMPTE ST 2110, Professional Media Over Managed IP Networks.
The Professional Media Over Managed IP Networks is a new standards suite that specifies the carriage, synchronization, and description of separate elementary essence streams over professional internet protocol (IP) networks in real-time for the purposes of live production, playout, and other professional media applications.
With SMPTE ST 2110 standards, intrafacility traffic now can be all-IP, which means that organisations can rely on one common data-center infrastructure rather than two separate facilities for SDI and IP switching/routing.
The foundation for the first SMPTE ST 2110 standards came from Video Services Forum (VSF) Technical Recommendation for Transport of Uncompressed Elementary Stream Media Over IP (TR-03), which VSF agreed to make available to SMPTE as a contribution toward the new suite of standards.
SMPTE ST 2110 standards make it possible to separately route and break away the essence streams — audio, video, and ancillary data. This advance simplifies, for example, the addition of captions, subtitles, and Teletext, as well as tasks such as the processing of multiple audio languages and types.
Each essence flow may be routed separately and brought together again at the endpoint. Each of the component flows — audio, video, and ancillary data (there may be multiple streams of each type) — are synchronized, so the essence streams are co-timed to one another while remaining independent.
