BROADCAST:
DVB
DVB-T
DVB-T is the world's most used digital terrestrial
television system
Consumes too much battery
DVB-H
Latest development from DVB family
Based on DVB-T technology
Consumes less battery (time slicing)
Improves the robustness of the difficult reception
environments with built-in antennas
BROADCAST:
MEDIA FLO
Developed by QUALCOMM
Based on FLO (Forward Link Only)
technology
It uses unidirectional COFDM
Less power consumption
Currently popular in North America
Frequency spectrum 716-722 MHz.
BROADCAST:
ISDB
The core standards of ISDB are ISDB-S,
ISDB-T, ISDB-C
12 GHz band ISDB-S uses PSK
modulation,
2.6 GHz band digital sound
broadcasting uses CDM
ISDB-T (VHF / UHF ) uses COFDM with
PSK/QAM
