In 2002 four main requirements of the DVB-H system were agreed: broadcast services for portable and mobile usage with 'acceptable quality'; a typical user environment, and so geographical coverage, as mobile radio; access to service while moving in a vehicle at high speed (as well as imperceptible handover when moving from one cell to another); and as much compatibility with existing digital terrestrial television (DVB-T), to allow sharing of network and transmission equipment.
DVB-H can offer a downstream channel at high data rates which can be used as standalone or as an enhancement of mobile telecommunication networks which many typical handheld terminals are able to access anyway.
If there are approximately ten or more bursted services in a DVB-H stream, the rate of the power saving for the front end could be up to 90%.
Time slicing technology is employed to reduce power consumption for small handheld terminals.
IP datagrams are transmitted as data bursts in small time slots.
DVB-H was formally adopted as ETSI standard EN 302 304 in November 2004.
The DVB-H specification (EN 302 304) can be downloaded from the official DVB-H website.
