Abstract

DVB-H happens to be the technical specification for the transmission of digital TV to mobile telephones and PDAs - handheld receivers. Published as a formal standard DVB-H is a physical layer specification designed to facilitate the efficient delivery of IP-encapsulated data over terrestrial networks. The creation of DVB-H, which is closely related to DVB-T, also entailed modifications of some other DVB standards dealing with data broadcasting, service Information, etc. It can be used as a bearer in concurrence with the DVB-IPDC systems layer specifications. A non-proprietary open standard, DVB-H has broad support and services are currently on air in more than ten nations.When the possibility of a dedicated DVB specification for broadcasting to handhelds was first discussed, it was in the context of the proven mobile performance of DVB-T, the widely adopted standard for digital terrestrial TV. The key applications considered were mobile TV, video streaming in general and file downloads, all targeted at handheld receivers that would operate with a limited battery life and in difficult reception conditions. This paper mainly concentrates on the comparative analysis carried out when DVBH has been applied to random data type and the results obtained are compared for QPSK, 16 and 64 QAM methods along with various code rates.
