Network Aspects forDVBH&TDMB

There is a strong demand for multimedia services or applications. The demand originated within
the mobile community combining the broadcasting service and the mobile service, but multimedia
applications can also be foreseen as an advanced broadcasting service. Operators need to decide
how they will deliver mobile TV and audio services to different types of customers in different
situations (pedestrians, in car, in house, etc.). Among different technologies DVB-H and T-DMB are
well-proofed techniques for mobile multimedia services in terms of coverage provided by
infrastructure and their relative costs.
Two systems have been developed in Europe; DVB-H, which is a mobile broadcast system derived
from DVB-T and T-DMB, which is a multimedia enabled version of T-DAB. They are designed for
handheld reception; in particular, DVB-H has been optimised to be included in small devices such as
mobile phones by using time slicing for less power consumption and an additional forward error
correction (FEC) to provide more robust signals.
These multimedia-broadcasting technologies may use the same frequency spectrum as
DVB-T/T-DAB, however due to their different applications, they are likely to require dedicated
networks. This report discusses various aspects in relation to the deployment of multimedia
services via DVB-H and T-DMB networks. The EBU document Tech 3317 'Planning parameters for
handheld reception' covers planning parameters for DVB-H and T-DMB systems in Bands III, IV, V and
the 1.5 GHz band.
