SVIP Activity Group
This group (SVIP = Define and research requirements for Studio Video over IP without SDI encapsulation) was formed on April 17, 2014. This activity group issued a Technical Recommendation (TR-03) on October 19, 2015 entitled "Transport of Uncompressed Elementary Stream Media over IP". This Technical Recommendation differs from current practices that bind video, audio, and ancillary data into the Serial Digital Interface (SDI) multiplex before encapsulation in IP, and instead provides for the carriage of video, audio, and ancillary data as separate elementary streams that can be individually forwarded through a network.
The SVIP group was asked to define 2110 Profiles and Levels for Increased Vendor-to-Vendor Interoperability during April, 2017 via a document received from the AIMS Technical Working Group . The main purpose of the request is to define appropriate feature profiles and performance levels for receivers implementing SMPTE ST 2110-20. Currently there are many possible profiles and levels defined in the Standard. This makes it very difficult for a vendor to clearly specify what a compliant receiver can accept. Correspondingly, this also makes it difficult for a customer to unambiguously state what they require from vendor equipment. The following direction is given to the SVIP Activity Group:
- The number of profiles and levels should be the minimum number required in order to address the issue raised above.
- Choices of profiles and levels must be supported and documented in business-driven user stories
- SVIP should consider the input document mentioned above when undertaking the activity authorized by the VSF No.: (2017-2).
- The group was asked to take appropriate steps to conclude this work and publish its results as soon as practicable.
