ABSTRACT
Just because something doesn’t do what you planned it to do doesn’t mean it is useless.
—Thomas Alva Edison
DVB-H technology is designed to use the digital terrestrial TV broadcast infrastructure to deliver multimedia services to mobiles. It can use the same spectrum slots used by digital TV. The DVB technology for handhelds has been designed to meet almost all the objectives of delivering a TV service to handhelds, which include:
● broadcast service reaching potentially unlimited users, ● delivery of sufficiently large transmitted power so that the mobiles
can work even within buildings, ● conservation of battery power used in receiving the TV service of
choice, ● use of the terrestrial broadcast spectrum, which is being rendered
free as a result of the digitalization of TV networks,
● robust coding and error correction to cater to highly variable signal strength conditions encountered in the handheld environment, and
● minimum infrastructure to roll out the TV services for mobiles. DVB-H can use the same infrastructure as DVB-T.
