OpenTV is the name of the operating system of the receiver (also 
known as its API). Consequently, the DVB 75SI enables you to fully 
utilise all channels that broadcast interactive services based on the 
OpenTV system (e.g. ARD, ZDF, RTL and the Viasat channels - 
subscription dependant). 
Interactive means that in addition to your normal role as a passive 
television viewer you'll be able to actually take part in the 
programme. When and if the transmission is prepared for it, you will 
be able to use your remote control to e.g. change camera view, 
participate in viewer polls, get more background information, browse 
through news, check the programme guide, etc. 
The system works by sending 'invisible' data in parallel with the 
television transmission. This data is called the 
interactive services.
When your DVB 75SI receives an interactive service it will load it into 
the receiver and execute it. This is very much similar to loading and 
executing a program on a PC. When the service is started it will take 
over the control of the receiver and it may take over the screen as 
well (using pictures, graphics and texts). "APPL" will be displayed on 
the front panel. As normal, you may control the receiver with the 
remote control. You can abort a service using the [exit] button, just 
as a change of channel using the [P+] or [P-] buttons will abort a 
running interactive application and the receiver will return to normal 
television mode. 
If the interactive application requires that information about your 
choices is sent back to the programme provider, your DVB 75SI 
automatically uses the built-in modem. The modem sends and 
receives the required information via your telephone connection. 
This way you may participate in direct television polls or order a 
movie. The modem is often referred to as the 'return channel' of the 
receiver. 
To receive and execute interactive services is normally free of 
charge, but access to them may be subject to subscription status. 
Use of the return channel is normally charged for as a normal 
telephone conversation. 
The DVB 75SI requires a normal telephone connection. If you have 
an ISDN connection, the DVB 75SI must be connected via an A/B 
output (normally available via an ISDN modem or a T/A adapter). If 
you do not have a normal telephone connection available, you 
cannot use the interactive services that require a return channel. 
Your DVB 75SI can easily be set to ignore all interactive services in 
case you temporarily only wish to watch normal television.
