 Provide more advanced services.  Downlink speed 14.4 Mbps and uplink speed 5.8 Mbps.

 Multimedia Broadcast Multicast Service is a broadcast TV, film, information and other media.  MBMS has the major benefits that it uses existing GSM & UMTS cellular network.  Uses multicast distribution.

 TDtv operates in the 3G spectrum bands at 1900MHz and 2010MHz.  TDtv allows UMTS operators to fully utilize their existing spectrum and base stations to offer mobile TV and multimedia packages without impacting other voice and data 3G services.

 1Seg is a mobile terrestrial digital audio/video and data broadcasting service in Japan.  In terrestrial digital broadcast each channel is divided into 13 segments. HDTV broadcast occupies 12 segments, and the remaining (13th) one segment is used for mobile receivers. Thus the name, '1seg'

 Digital Multimedia Broadcasting (DMB) is a digital radio transmission system for sending multimedia (radio, TV, and datacasting) to mobile phones.  It uses radio frequency bands band III (VHF) and L (UHF).  In DMB uses MPEG-4 part 10 for video & MPEG-4 part 3 BSAC for audio.

 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

 Developed by QUALCOMM  Based on FLO (Forward Link Only) technology  It uses unidirectional COFDM  Less power consumption  Currently popular in North America  Frequency spectrum MHz.

 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
