DVB-H and UMTS

Studies have been conducted in relation to the roll-out of DVB-H and its possible integration
with cellular networks. DVB-H is backward-compatible with DVB-T, and
the two formats can be mixed in the same digital multiplex. While one multiplex can
convey six to eight DVB-T channels, it can be used for up to fifty DVB-H channels.
The DVB technology can be kept separate and used to deliver content to DVBH-
enabled terminals, or a cellular technology, such as UMTS, could be used to
provide a reverse channel that allows users to browse for content and, when content
selection is made, have that content delivered over a DVB-T channel (Figure 4.67).
This would mean that some degree of cooperation would be required between the
UMTS network operator and a broadcaster. The convergence of telecommunications
and entertainment services means that such cooperation is very likely.
