This paper gives a brief review of the new Digital Video Broadcasting—Handheld (DVB-H) standard. This is based on the earlier standard DVB-T, which is used for terrestrial digital TV broadcasting.
The new extension brings features that make it possible to receive digital video broadcast type services in handheld, mobile terminals. The paper discusses the key technology elements—4K mode and in-depth interleavers, time slicing and additional forward error correction—in some detail.
It also gives extensive range of performance results based on laboratory measurements and real field tests. Finally it presents viewpoints relevant for DVB-H network design and system use in general.
History and Background:
The Digital Video Broadcast (DVB) Project started research work related to mobile reception of DVB—Terrestrial (DVB-T) signals as early as 1998, accompanying the introduction of commercial terrestrial digital TV services in Europe.
In 2000, the EU-sponsored Motivate (Mobile Television and Innovative Receivers) project concluded that mobile reception of DVB-T is possible but it implies dedicated broadcast networks, as such mobile services are more demanding in robustness (i.e., constellation and coding rate) than broadcast networks planned for fixed DVB-T reception.
