Industry Organizations supporting Open Specifications
Several industry groups have been collaborating to achieve open standards in IP-based systems. These organisations provide different experience and skill sets and their contributions are complementary to each other, ensuring that the interests of both media companies and their industry suppliers are considered.
Joint Task Force on Networked Media (JT-NM)
The JT-NM and the Reference Architecture V1.0 (RA V1.0) is a joint effort of the AMWA, EBU, SMPTE and VSF. The plan is to develop a common, open approach to developing user requirements for video over IP in the professional domain. It has published a Reference Architecture, which contains best practices and recommendations for other groups to use in creating standards and specifications. A lot of the Studio Video over IP work correlates strongly with RA V1.0, but the RA stopped short of moving into the technical solutions, the space where the VSF SVIP and AMWA Networked Media Incubator groups operate.
The JT-NM also publishes a roadmap to explain which standards and specifications enable the JT-NM Reference Architecture, how the range of underlying technologies is expected to evolve and approximately when it is believed that those standards and specifications will be widely available to build interoperable multi-vendor systems.
Advanced Media Workflow Association (AMWA)
The AMWA has traditionally focused on software applications in the professional video space and, as such, its work is an excellent complement to that of the VSF. Specifically, the Networked Media Incubator project builds on the recommendations of the JT-NM RA and provides an environment which is developer and implementation focused. The goal is to support media suppliers to get products based on open and interoperable standards into the field as quickly as possible – and thus enable end users to build best-of-breed systems. Much of this effort is applied within practical interoperability workshops.
European Broadcasting Union (EBU)
The EBU provides technical input, representing end users from 56 countries across Europe.
Society of Motion Picture & Television Engineers (SMPTE)
The SMPTE has brought due process and standardization to advance the adoption of IP based systems. The SMPTE ST 2110 suite of standards specifies the carriage, synchronization, and description of separate elementary essence streams over IP for real-time production, playout, and other professional media applications. The foundation for ST 2110 standards is VSF Technical Recommendation, TR-03, for Transport of Uncompressed Elementary Stream Media Over IP.
Video Services Forum
For many years, the VSF Studio Video over IP group (SVIP) has been active in developing Technical Recommendations. It created TR-04, the dominant professional video-over-IP, primarily intended to move video between facilities and, more recently, TR-03 for use within facilities. These were later used as the basis for SMPTE standards ST2022 and ST2110. The VSF generally focuses on lower levels of video transport.
The Alliance for IP Media Solutions (AIMS)
This initiative seeks to promote an open approach to video over IP standards. They do not collect user requirements and do not create technical solutions. AIMS is primarily a marketing group and has led substantial educational "IP Showcase" events at major trade shows.
