Quick Review of Tutorial
Broadcast networks are unidirectional (i.e. downlink only)
They are efficient for broadcasting but need a bidirectional technology as uplink channel
State of the art: 3GPP + DVB/MediaFLO/DMB
Covers partially uplink channel problems and the coverage problems
There are commercial products capable of quasi „handovers“ between 3GPP-DVB-H
Problem: Indoor DigitalTV coverage

Solution
Target is to use WLAN indoors and enable handovers between and DVB
IEEE aa
Problem areas
Synchronization
No IEEE problem, but studies going on...
Coexistence ???

So What?
DVB will start a work item on the subject in November
You will then hear more about this topic
Many companies have broadcast units
Home entertainment + mobile Services: Especially for operators handover between and DVB is important
Please talk to your colleagues and share your ideas with us
PAR/5C coming soon for TG in
