MOBILE TV TECHNOLOGIES:

CELLULAR: 3 G Provide more advanced services. Ø Downlink speed 14. 4 Mbps and uplink speed 5. 8 Mbps. Ø

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

CELLULAR: TDTV TDtv operates in the 3 G spectrum bands at 1900 MHz and 2010 MHz. Ø 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 3 G services. Ø

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

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

BROADCAST: DVB Ø DVB-T Ø Ø Ø DVB-T is the world's most used digital terrestrial television system Consumes too much battery DVB-H Ø Ø Latest development from DVB family Based on DVB-T technology Ø Consumes less battery (time slicing) Ø Improves the robustness of the difficult reception environments with built-in antennas

BROADCAST: MEDIA FLO Developed by QUALCOMM Ø Based on FLO (Forward Link Only) technology Ø It uses unidirectional COFDM Ø Less power consumption Ø Currently popular in North America Ø Frequency spectrum 716 -722 MHz. Ø

BROADCAST: ISDB The core standards of ISDB are ISDB-S, ISDB-T, ISDB-C Ø 12 GHz band ISDB-S uses PSK modulation, Ø 2. 6 GHz band digital sound broadcasting uses CDM Ø ISDB-T (VHF / UHF ) uses COFDM with PSK/QAM Ø
