Efficient HDTV and 3DTV Services over DVB-T2 using multiple PLPs with layered media

The high bit rates of high-definition or 3D-services require a huge share of the valuable terrestrial spectrum, especially when targeting wide coverage areas. This article describes how to provide future services with the state-of-the-art digital terrestrial TV technology DVB-T2 in a flexible and cost-efficient way. The combination of layered media such as the scalable and 3D extension of the H.264/AVC or emerging H.265/HEVC format with the physical layer pipes feature of DVB-T2 enables flexible broadcast of services with differentiated protection of the quality layers. This opens up new ways of service provisioning such as graceful degradation for mobile or fixed reception. This article shows how existing DVB-T2 and MPEG-2 transport stream mechanisms need to be configured for offering such services over DVB-T2. A detailed description of the setup of such services and the involved components is given
