TAG: TV distribution

It’s the permanent transport of the TV signals towards the end users, from the central head-end (e.g., in Rome) to all transmitters located throughout the country, or to the servers for the distribution on the Internet, or to the satellite uplink station. It is also defined as primary distribution, to distinguish if from the direct distribution to the final users (broadcasting).

New DVB technology to serve satellite customers and to feed terrestrial transmitters

Today, the satellite distribution of DVB-T2 multiplexes to terrestrial transmitters located throughout the territory requires dedicated transponders for the transport of the relevant T2-MI (Modulator Interface) streams, which are not directly accessible also for direct-to-home reception by standard satellite receivers. This causes duplication of the needed satellite bandwidth, with the associated costs. To overcome this problem, DVB (Digital Video Broadcasting) has activated a new ad-hoc group, named TM-T-JSI, with the purpose of defining an optimized way to transport DVB-T/T2 multiplexes from a national head-end to the terrestrial transmitters, while allowing at the same time direct reception via DVB-S/S2 commercial satellite receivers.
