IPDC 18Crypt

ETSI Standard for Service Purchase and Protection (SPP)

Optimised for mobile broadcast

IPSec, ISMACryp or SRTP using AES-128 and RSA

Utilises DRM functionalities as well (OMA DRM)

OMA DRM2.0

Can be applied for: Pay-TV, content protection, ID card, credit card, and so forth.

Grant permission for media objects for specific users independent of the media object formats and the given operating system or run-time environment

Examples: games, ring tones, photos, music clips, video clips, streaming media, etc

Used together with 18Crypt

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

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

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

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.

Preparation

Each group should have at least one computer with the following software installed:

VLC 0.8.6i: http://www.videolan.org/mirrorgeo.php?file=vlc/0.8.6i/win32/vlc-0.8.6i-win32.exe

Darwin Streaming Server (patched by me to work with all Windows versions)

 available for download here: http://imi.aau.dk/~allan/dss.rar

Unpack it (using WinRAR), so the path to the software is: c:\Program

Files\Darwin Streaming Server

In this folder run: Install.bat (on Vista run it is as administrator)

Perl interpreter- For windows, choose:

 http://downloads.activestate.com/ActivePerl/Windows/5.10/ActivePerl-
