Activity Groups
Through VSF Activity Groups (AGs), VSF members advance work targeting specific technical approaches and interoperability issues. In addition to holding regular meetings, these groups provide progress reports at the VSF’s in-person May and October meetings and supply input and expertise to other industry standards bodies on behalf of the VSF.
CURRENT VSF ACTIVITY GROUPS
Reliable Internet Stream Transport (RIST)
Objective:
- Address the lack of compatibility between devices that provide reliable low-latency transport of high-quality video over public IP networks.
Tasks:
- Develop further RIST specifications that include additional features. Merrick.Ackermans@outlook.com,
Co-Chairs:
- Rick Ackermans, CBS Operations
- Wes Simpson, LearnIPvideo
Internet Protocol Media Experience (IPMX)
Objectives:
- Develop a full-stack, interoperable AV-over-IP profile for the pro AV industry that is based on SMPTE ST 2110 and NMOS.
Tasks:
- Create a standard set of protocols and specifications for managing and delivering audiovisual media over IP networks. Meet the areas of need as outlined in the AIMS IPMX roadmap.
Co-Chairs:
- Jean Lapierre, Matrox
- Jack Douglass, PacketStorm
Ground-Cloud-Cloud-Ground (GCCG)
Objectives:
- Determine if a common set of requirements for Ground-to-Cloud-to-Cloud-to-Ground media essence communications exists.
- If common requirements exist, establish a common technical approach (perhaps to be documented in a VSF Technical Recommendation) for communication of media essences from G-C-C-G.
Tasks:
- Seek appropriate members to participate in the activity
- Gather requirements through informal communication with other end-users and cloud providers
- Gather technical stakeholders and draft a technical approach if common requirements exist
- Form the approach in a VSF Technical Recommendation as appropriate
Co-Chairs:
- John Mailhot, Imagine Communications
- Andy Rayner, Appear
Review of CODEC Options for AV-Over-IP protocols in Pro AV Applications
Objective:
Establish operating points for documented IPMX use cases and criteria to be measured for candidate codecs against each use case, as well as a vendor self-testing program with sufficient data to support decision-making by external groups.
Tasks:
- Establish IPMX system operating points for evaluation purposes, based on the Use Cases (see JT-NM ref).
- Determine criteria to be measured at the operating points.
- Develop targets or ranges for each criterion, for each use case.
- Develop and publish a test plan for objective testing of the criteria at the operating points.
- Develop a list of suitable candidate codecs and encourage vendors to self-test against the published plan and criteria.
- Document the results to support a recommendation of codec(s) for each use case.
- Publish the results.
