It is possible to receive digital terrestrial television (DTT) with certain mobile devices, however, the reception quality can be degraded due to a broadcast format that is not suitable, and price of high power consumption. Thanks to the TMP, a series of channels and services specially designed for mobile programs can be accessed even if we generally found first channels already broadcast on TNT.
The TMP may also offer a range of radios as well as complementary services (without direct interaction due to the standard operated), but this is rare: the available resource is limited, it is often used exclusively for television.
The standards used for the TMP in the world are many. The main standards are 1seg, used in Japan, T-DMB, operated in Korea, the owner MediaFLO standard in the United States and DVB-H and DVB-SH in Europe in 2008 adopted standards.
DVB-H (Digital Video Broadcasting – Handheld) – Europe, Asia, South Africa
ATSC-M / H (ATSC Mobile / Handheld) – North America
T-DMB (Terrestrial Digital Broadcast Mulitmedia) – South Korea
1seg (One Segment), Mobile TV system based on the ISDB-T standard – Japan
MediaFLO – launched in the United States, experimentation in the United Kingdom and Germany
DMB-T / H (now named DTMB, Digital Terrestrial Multimedia Broadcast) – China, Hong Kong and Macao
DAB-IP (Digital Audio Broadcast) – United Kingdom
iMB (Integrated Mobile Broadcast, 3GPP MBMS) – experiment in the UK
Broadcast satellite (possibly with a land component):
DVB-SH (Digital Video Broadcasting – Satellite for Handhelds) – Europe
S-DMB (Satellite Digital Multimedia Broadcast) – South Korea
CMMB (China Mobile Multimedia Broadcasting) – China
Future iMB technology is envisaged for the dissemination of the mobile phone frequencies, frequencies for which the mobile operators already licensed.
Competition and differences with the 3G reception
It is also possible to receive satellite internet network using the 3G1 and in some countries, access to broadband internet wireless technology Wimax.
A TMP receiver uses no return path to select channels. TMP unconnected receivers can be interactive as opposed to 3G terminals, except TV equipment nomadic TMP / Wifi or laptops WIFI / Ethernet equipped with a feature of receipt of the TMP.
The number of TMP receivers operating on the same coverage is not limited but the number of 3G mobile it is limited by the available bandwidth of the 3G network. The number of services (TV, radio or data) is fixed by a technical optimization and associated regulations.
