Current Projects: In process for completion in the coming year are updates of numerous existing standards including ANSI/SCTE 53 2008, "Methods for Asynchronous Data Services Transport"; ANSI/SCTE 54 2009, "Digital Video Service Multiplex and Transport System Standard for Cable Television"; ANSI/SCTE 65 2008, "Service Information Delivered Out-of-Band for Digital Cable Television"; ANSI/SCTE 43 2005, Digital Video Systems Characteristics Standard for Cable Television"; ANSI/SCTE 127 2007, "Carriage of Vertical Blanking Interval (VBI) Data in North American Digital Television Bitstreams"; ANSI/SCTE 162 2009 (J-STD-070-2010), "Emergency Alert Signaling for the Home Network" – to be carried out jointly with the CEA; ANSI/SCTE 172 2011, "Constraints on AVC Video Coding for Digital Program Insertion", as well as updates to ANSI/SCTE 30 2009, "Digital Program Insertion Splicing API" and what is now a "frequent flier" in terms of continuous improvement, ANSI/SCTE 35 2013a, "Digital Program Insertion Cueing Message for Cable. 

New projects on the docket include standardization of CableLabs specifications related to adaptive steaming Encoder Boundary Point and their Enhanced Scheduling and Notification Interface (ESNI). Adaptive streaming as also being addressed, with proposals for new standards related to codecs and carriage over cable networks. The DASH (Dynamic Adaptive Streaming over HTTP) ad-hoc group was promoted to full ‘Working Group’ status to help progress the important work of high-efficiency coding and the transport of IP video.

Advanced Advertising Standards
Working Group 5 of the Digital Video Subcommittee 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.
