TV at the stadium

TV at the stadium

Transmitter(s) at the stadium broadcast data via DVB-H, forming a local ”TV channel”

This is received by cell phones in the audience

TV at the stadium

Through service discovery, the phones find services in the DVB-H ESG

Live feeds

Wallpapers

Ring tones

Gaming & betting

Sponsoring

Voting

At the stadium, the users can view live feeds to which they have subscribed

CA and DVB-H deliver to subscribers only

A subscriber key on the handset opens the TV channel for the viewer

TV at the stadium

In the DVB-H transport stream, ringtones, wallpapers etc. are send via file cast and offered for sale as well

DRM handles the material

A viewer can always access, but only view the material upon payment

TV at the stadium

File cast games - quizzes for example - are available to the viewers.

By means of SMS, GPRS or other data link, the result is submitted to the backend

Users can thus participate in lotteries, competitions, live bets etc.

Of course, if someone wants to support the young league financially, they should be encouraged...

Behind the frontend, an SMS service charges the user via the phone bill depending on the amount chosen by the user.

...and why not let the viewers vote for the player of the match?

A lottery prize for “guessing” the right player of the match motivates the users.

This is also done via SMS, and again the user does not see the SMS send by the service - it’s all in the background.
