SVIP (Studio Video over IP) Activity Group
This group has accomplished a number of valuable tasks in the past four years. It was originally formed on April 17, 2014, and has produced three key Technical Recommendations which are available for free download:
- Technical Recommendation (TR-03) entitled "Transport of Uncompressed Elementary Stream Media over IP" was released on October 19, 2015. This specification provides for the carriage of video, audio, and ancillary data as separate elementary streams that can be individually forwarded through an IP network.
- Technical Recommendation (TR-04) entitled "Utilization of ST-2022-6 Media Flows within a VSF TR-03 Environment" followed quickly and was released on November 12, 2015. This specification builds on the work of TR-03 to allow complete SDI signals that have been encapsulated in an intact, fully multiplexed manner using ST 2022-6 to more easily interoperate with TR-03 based system by using compatible RTP timestamping and common SDP constructs.
- Technical Recommendation (TR-05) entitled "Essential Formats and Descriptions for Interoperability of SMPTE ST 2110-20 Video Signals" was released on June 23, 2018, to support a goal of enhanced system interoperability for ST 2110-based networks. This specification completely defines a series of video formats that are commonly used in professional video production applications.
The SVIP group is currently working to develop an system for collecting widely used video format descriptions in an open, central repository. The team has been authorized under VSF Activity Group Authorization 2018-2 to undertake the following tasks:
- Develop an extensible table that is a single, central repository which identifies the key technical metadata elements for a selected set of video formats, with sufficient detail to enable implementers (suppliers, integrators and end users) to easily create interoperable systems.
- Publish this table in a form that is human readable, referenceable, and consumable. This may include a canonical naming system to uniquely identify each format.
- Develop a machine readable version of this table (using JSON, XML, or similar).
- Create a set of rules/procedures for capturing, vetting and adding new video formats and their attributes to the table.
- Publish the table by way of AMWA, VSF, AIMS, GitHub or similar.
- Determine if there is a need to provide the table to industry in some type of formal registry (via SMPTE RA, IETF or who?). If so, then develop an action plan and process.
Work on these tasks is underway. All VSF members are enthusiatically invited to participate – please contact Wes Simpson for more information.
