CELLULAR3G

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

11
CELLULAR MBMS

• 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.

12
CELLULAR TDtv

• 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.

BROADCAST1 Seg

• 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'

14
BROADCASTDMB

• 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.

15
BROADCASTDVB

• 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

16
BROADCASTMedia 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.

17
BROADCASTISDB

• 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
