The document provides an overview of DVB-H (Digital Video Broadcasting - Handheld), a standard for delivering television and video services to mobile devices. It discusses key aspects of DVB-H including its technical implementation based on DVB-T, protocols like IPDC (IP Datacast) and MPE-FEC, and services like hierarchical offerings and parallel services. The presentation concludes that DVB-H provides a fully standardized end-to-end mobile TV service that is backward compatible, developed new features for mobiles, is IP-based, and is being tested and rolled out worldwide and in North America.
