The European System for Digital Terrestrial Television Broadcasting
In the framework of the DVB, RACE dTTb and ACTS VALIDATE European projects, the RAI Research Centre has directly contributed to the definition and validation of the DVB system for digital terrestrial television broadcasting (DVB-T). The system, allowing fixed and portable reception, is based on OFDM technique with a variety of modulation/channel coding configurations, and is characterised by two operational modes: with 2K carriers for conventional multi-frequency networks (MFN), and with 8K carriers to cover also single frequency networks (SFN).
This contribution presents the DVB-T system main features as well as its performance as evaluated through computer simulations and laboratory tests on the second dTTb demonstrator carried out by the RAI Research Centre in the framework of the VALIDATE project.
