2. Quick Review to Tutorial
Broadcast networks are unidirectional (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

6. So What? DVB will start a work item on that by November
You will hear more about this topic then
Most 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
