New : The DVB-H approach & objectives
Various modes… (16/64 QAM…).Most of them reach high mobility with diversity (2 receivers)
DVB-T: the constraints to mobility DVB-H targets
Important power consumption due to the high bit rate received in continuous mode
Limited awareness of compatibility with mobile application/image
Must be as close as possible to DVB-TNeed to work with single receiver
for handheld devices – MPE FEC
TIME SLICING (allows a trade-off between power consumption and the bit rate needed by the application)
Marketing/strong awareness/contribution by large players
• DVB-H : New DVB-T based standard since Q4/2003 to develop broadcast services (including TV) on mobile phones
• DVB-H = Mobile DVB-T + Time Slicing + MPE-FEC

DIB7000-H: Silicon Solutions are ready for market
♦ DiB 7000 H : IC for DVB-H : embed all algorithms of DVB-T IC DiB3000MC
♦ Additional features for DVB-H:
• enhanced FEC : MPE-FEC - Allows a Maximum Doppler compensation (130 Hz) in single almost as good in a Diversity2 DVB-T without MPE-FEC
- Allows a C/N improvement by around 3 dB at low speed
• reduced power consumption : TIME SLICING
-Allows to divide the power consumption of the front-end by 10
200mW in DVB-T 20 mW in DVB-H

New network = New Business ModelWho will pay ? Broadcasters or Mobile Operators ?
• Monthly Subscription
• TV on demand
• Channels on demand
• Program on demand
• Broadcaster delivers content
• Mobile operator sendsinvoice
Pay TV Model
$$$
Issue : While a consumer watches TV,
he does not use his phone, but he uses
battery … but more predictible revenue
• Events based TV (reality shows, sports …)
• Links to SMS, Voting, Web, Wap
• Stimulates Data
• Broadcaster delivers content
• Mobile operator sendsinvoice
Free TV + Interactive
$$$
The consumer watches TV for free,
and is stimulated to send data on
GPRS and UMTS networks, he
becomes sticky with the operator …
But less predicatible revenue
