� Overlay network in broadcast band (DVB-H, DVB-SH, MediaFLO or T-DMB)
� Unicast
� Broadcast on 3G with MBMS
Terrestrial broadcast :Build an overlay network

(DVB-H, DVB-SH, MediaFLO or T-DMB)� Broadcast on 3G with MBMS
� Evolution with WiMAX/3G LTE
� Korean S-DMB, Chinese S-TiMi
� Hybrid DVB-SH
� Re-use of mobile sites for low-power transmitter
Hybrid satellite/terrestrial broadcast : National coverage
Delivering TV By Leveraging Cellular/3G Network (or WiMAX/LTE)
Unicast
� Only active users consumes transmission resource
� Very limited number of active users simultaneously
Multimedia Broadcast Multicast Service (MBMS)
Unicast : data is sent as many
times as users in the network

Service (MBMS)
� Allows operators to broadcast Multimedia content to all mobiles in any cell(s) of the network
� Unlimited number of userBroadcast : data is sent only
once within network
TV program
Both are consuming very precious 3G spectrum resource. Makes more sense with
WiMAX/LTE (technology with much higher spectrum efficiency)
Digital Video Broadcast – Handheld (DVB-H)
It was formally adopted as an ETSI standard in November 2004
A non-proprietary open standard, DVB-H has broad support across the industry

Does not use cellular spectrum, instead it requires a broadcast spectrum i.e. UHF
Also approved by the 3GPP to use in conjunction with the cellular network
General business model: cooperation between mobile operator and media company
� DVB-SH: Evolution of DVB-H, using UHF or higher frequencies (such as S-Band 2.2GHz)
Low-power terrestrial repeaters for urban areas / indoor TV broadcast
Cellular network for limited audience TV, VOD and interactivity
OptionalOptional High-power satellite for country coverage

DVB-H
DVB-SH
UHF
� Almost fully utilized by analog
TV broadcast
� Digitalization target to complete
in 2015 (?)
L-Band� 2 blocks of 24MHz have already
been allocated to PT. Mentari
Multimedia (M2V)
� DVB-T has been used to provide
in-car TV entertainment
S-Band 2.2GHz� Currently still used for P2P
microwave, no immediate plan to
provide it for digital broadcasting
S-Band 2.6GHz
� Currently used for DTH satellite, &
BWA. Heavily contested band
between broadcast, LTE and WiMAX
