There’s a New Study Group in SMPTE
The Study Group on Required Application Protocol Standards for IP-Based Media Production will soon be starting to explore prospective Media Industry layering models and standards requirements for interoperability of production applications running on IP-based media networks. The project details can be reviewed by following the link below:
Purpose: This Study Group will explore prospective Media Industry layering models and standards requirements for interoperability of production applications running on IP-based media networks. These are the higher-level structures associated with workflow, production application functions, services interoperability, etc., which have not been the subject of significant attention within standards and specifications like SMPTE 2110, NMOS, or others.
Problem to be solved: There are currently insufficient application protocol standards to facilitate the development of interoperable media production applications running on IP-based media networks. In particular (a) there is no widely accepted layered model for media production and (b) there is not enough common language describing the application-oriented layers above media transport and device control to be able to address interoperability in those higher layers.
Project scope: This group's scope will be to address and identify standards requirements to support interoperability of production application functions running in layers above the "plumbing" (i.e. media transport & device control, and data networking) layers. While there may be some commentary around existing standards, it will not be the focus of this group’s work. They will focus on recommending a common layering model for professional media systems and suggesting next steps.
- A.) Align on a layering model
- i) Identify the layers and functions of each layer.
- ii) Develop appropriate nomenclature to use for the rest of the study.
- iii) Confirm which layers will be in scope and out of scope of this study.
- B.) Identify standards requirements for in-scope layers
- i) Develop a roster of application functions needed to support IP network-based production.
- ii) Identify interoperability requirements for applications that provide the listed functions.
- iii) Identify existing standards and specifications (from SMPTE and others) that aim to address application interoperability (excluding schemes that are focused on lower (i.e. out of scope) layers of the model).
- iv) Perform a gap analysis to provide a list of areas requiring further work.
- C.) Recommend ways to go forward
- i) Suggest modifications to existing standards and/or creation of new standards - include both increases and decreases of scope.
- ii) Identify areas where confusion exists, both with SMPTE and among SDOs, trade associations, etc.
- iii) Identify collaboration opportunities.
- iv) Look for overlapping / duplicated work streams that could be merged or trimmed.
- v) Suggest ways of coordinating diverse activities in this area.
- vi) Suggest ways of promoting layering concepts among SDOs and industry.
