The Future
MOBILE BROADCASTING INTEGRATION
New opportunity for DVB-T?

unspecific information to all users in a given area 
broadcasting
Large memories introduce paradigm shift:
– - ‘live services’ are already becoming the exception
– - mass storage in receivers decouples consumption
from production (c.f. TV-Anytime)
 filter & store in user terminal
 local interactivity on stored content
 reaction by mobile communication (e.g. order a
product)
MOBILE BROADCASTING INTEGRATION

Integrating a 512 MB flash in the User Terminal should not be an
issue in 2006; today prices of Flash EEPROM is around 0,3 €/MB
Capacity increase exceeds Moore’s law: factor 2 every year, at
constant price
Based on present trends, a 0,01 €/ Mbytes could be reached in 2008

THE POSSIBLE ROLE OF SATCOMS
BEYOND IMT 2000 :
SOME CHALLENGEs
Co-operative Networks
Wireless Protocols, all IP (v6)
Security across different layers & Privacy,
Resource and Mobility management,
QoS, Network management, flexible billing system,
Advanced network architectures, new accesses

CONCLUSIONS

EU fully committed to support the development of
Systems beyond IMT 2000;

Approach based on interoperability and co-operative
inter working of heterogeneous networks;

Standards will be critical to the overall success;

Standardisation requirements likely to move towards
higher layers;

Standards time frame around 2007 ?;

Co operation between a multiplicity of fora may
become critical
