Charter:
Digital Video Subcommittee identifies requirements and develops standards for the design and operation of systems for delivery of video, audio, and associated data for the Cable Industry, coordinating as necessary with organizations such as ATSC, CTA, SMPTE, NCTA, and CableLabs.
DVS specializations:
- Advanced video codecs: HDR/WCG, HEVC, AVC, and Ultra HD.
- Content security: DRM, CAS (over cable), and encryption (for content over IP).
- Advanced advertising technology: Addressable ad insertion, linear and on-demand ad insertion interfaces, digital cueing and splicing, alternate content/blackout, and metadata.
- New media: Virtual reality and augmented reality.
- Next-generation audio: Immersive audio, AC-4, and MPEG-H.
- Next-generation systems: All-IP transition, virtualization, and more to come.
- Advanced transport for IP video: CMAF and MPEG-DASH.
Working Groups:
1 – Video and Audio Services
The Video and Audio Services Working Group focuses on advanced audio codecs, advanced coding technologies, and high dynamic range video.
2 – Data and Transport Applications
3 – Network Architecture and Management
4 – Transmission and Distribution
5 – Digital Program Insertion
The Digital Program Insertion Working Group is focused on the development of standards and practices that support an important revenue stream for the cable industry: advertising insertion into programs. Affecting both the content providers and the operators themselves, advertising revenue continues to grow in importance and the variety of programming vehicles expands beyond traditional QAM-based "linear television" to include IP distribution, On Demand, and TV Everywhere. The variety of transport, compression, and related technology changes make the aspect of digital program insertion of advertising a challenging and exciting area. The end-to-end infrastructure diagram, which is shown below provides an overview of the areas that WG5/DPI impacts.

DVS Next Generation Systems
The DVS Next Generation Systems Ad-hoc Group monitors technology advances in the industry and advises DVS on technology that should be investigated or pursued, work being conducted in other standards development organizations for which DVS should establish liaisons, and needs or opportunities in the cable industry that should be addressed by DVS.
