Abstract
The European DVB-T standard includes a large number of transmission modes able to adapt the COFDM signal to a wide variety of broadcasting services. Among others, the hierarchical modulation mode allows to broadcast, on the same radio frequency channel two independent transport streams (MPEG-TS) having each a dedicated protection. With this apparently strange & complex modulation mode, it becomes possible to imagine new broadcast services: to define two distinct coverage areas for a transmitter, to address both mobile and static receivers, To simulcast digital programs in standard (SDTV) and high definition (HDTV) formats, combined with the natural advantage to operate several transmitters in an iso frequency network (SFN - Single Frequency Network), the hierarchical modulation highlights the tremendous capacities of the DVB-T system. After an educational explanation of the COFDM signal, details are given on the way to perform simulcast or mobile services with DVB-T hierarchical modulation. Is the DVB-T hierarchical modulation an opportunity for new digital terrestrial TV services? The author intends to bring his conviction in this paper.

bio
GERARD FARIA is the Director of the Research department for ITIS in Rennes, France. He graduated in 1978 from the Technical University of Paris (France). In 1988, after more than ten years of practical engineering experience in digital design he was one of the founders of the ITIS company. He has been involved in the design of the company's DAB and DVB product ranges and manages the ITIS contribution in several European Collaborative projects (RACE, ACTS). His primary responsibilities include managing the ITIS research engineers team and driving the ITIS research programmes oriented to digital Radio and TV broadcasting domains. Since 1996, Gerard Faria has engaged in the standardisation works of the European Telecommunication Standard Institute (ETSI) where he acts as a DAB network specialist. He is also the ITIS representative in the European Forums driving the DAB (Worldab) and the DVB (DVB-TM) technologies.
