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.

Advanced advertising technology: Addressable ad insertion, linear and on-demand ad insertion interfaces, digital cueing and splicing, alternate content/blackout, and metadata.
