MAINDATA Introduces DVB-H IP Encapsulator Enabling New Mobile TV Broadcast Services
MAINDATA introduces DVB-H IPE crucial head-end equipment for introducing TV broadcast services to mobile networks.
(PRWEB) June 3, 2005 -- DVB-H opens doors for mobile operators to provide
attractive mobile TV broadcast e.g. sports, music. Mobile TV services have high
selling potential mainly to the young audience. DVB-H brings mobile TV
experience to mobile phone users and is candidate of important next wave revenue
streams - similar to SMS - for mobile operators by moderate investment into
their networks. There are no changes of existing GSM networks are
necessary.
2G and 3G mobile networks are based on point-to-point
protocols. Because of this “point-to-point“ unicast nature of transmission TV
programming delivered just to a single user almost completely “eats“ capacity of
the cell. Single cell transmitter capacity is around 380 kbps, while MPEG-4
compression video requires 200-400 kbps. As a consequence point-to-point
architecture prohibits providing of Mobile TV services at affordable price and
acceptable quality to an end-user. http://www.maindata.info/doc/MAINDATA-DVB-H.pps

DVB-H IPE allows transmission of over 10 TV programming within a single DVB-H
broadcast stream (e.g. 12 TV channels each of 300 kbps within 4 Mbps transport
stream).

DVB-H is
built at a point-to-multipoint “Broadcast type“ of protocol. This allows
effective re-use of network resources and hence transmitting TV programming to
unlimited number of users via a same bandwidth required to one user. In a DVB-H
Broadcast type of transmission there is no difference in bandwidth consumption
between one user and 1000 users. Furthermore TV Programming is broadcast via DVB
network and not a GSM network - leaving capacity of mobile 2G, 3G networks
unaffected. Integration of DVB-H with mobile networks does take place within
mobile phone. Such a handset supports both networks. Four major mobile phones
manufacturers are introducing DVB-H enabled mobile phones. This is backed by
development of DVB-H chips.
From an investment point of view, DVB-H
network can use the same frequencies and transmitters as terrestrial digital
television network (DVB-T) which is already operational in several
countries.
DVB-H standard has evolved from DVB-T by adding three crucial
new features targeted at improved mobile broadcast capabilities and longer
handsets battery life. Majority of the “mobility enabling“ features are hosted
in IP Encapsulator, performing “time slicing“ and MPE FEC (forward error
correction) accompanied with extended PSI/SI tables (Service and program
information tables).
Unlike the DVB-S and DVB-T standards, DVB-H network
is fully IP based where not only IP packets but also video and audio streams are
encapsulated into IP packets.
