The DVB project: philosophy and core system

摘要

The DVB (Digital Video Broadcasting) project was established to develop comprehensive specifications for digital television broadcasting. In three years it has completed work on a range of specifications covering broadcast delivery by all currently used means. The systems are founded on the MPEG-2 coding and multiplex specifications. Additional elements have been added to meet specific broadcasting requirements. The first DVB services in Europe, and in other parts of the world using the systems, will be of conventional quality, but the DVB systems can be used for transporting any data content, or image and sound formats, required by the programme service provider, including HDTV.
