(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

TV program

TV program


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-SH in S-Band (US): ICO Selects Alcatel-Lucent

1st Satellite in orbit Q1 08


: Alcatel-Lucent scope

- ICO vehicular terminals will include DVB-SH multi-band (incl. UHF) chipsets- Large screen DVB-SH terminals will be UHF and S-Band

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

Summary: Pro/Cons of Different Technologies for Mobile Operators

Impact to voice/

broadband

Huge impact

Big impact

Scalability

Impossible for massive usage

One time deployment for unlimited user


DVB

number of contents (today)
