3. The iTV application
It is not always essential to use additional technologies in order to implement concepts and contents of interactive television. A creative combination of classic media e.g. an analogue television, telephone and laptop, already offers many opportunities.

In many cases however, direct interaction in front of and with the television set is desirable, e.g. in order to direct the contents, to intensify the experience or simply to ease payment. This form of interaction is facilitated by so-called "iTV applications".

In terms of contents, one could compare an iTV application with the "extras" on a DVD. In other words this is a self-contained multimedia offering, although it is based on television contents.

The potential scope of an iTV application is larger than that of DVD extras, although smaller than that of PC applications or the World Wide Web.

In order to present and interact with iTV applications, one requires a computer unit in or on the television set. There are also further technical requirements such as WAN interfaces or access to the standard functions of the receiver unit.

The effective configuration of iTV applications is difficult.

On the other hand, the iTV applications offer effects and options which no classic media can provide. Central advantages of the media television/receiver and PC are combined in the iTV application and further enhanced. This combination promotes many content-based and business concepts such as: Interactive television is often understood in the narrow sense as simply being the provision of iTV applications.

The significance of iTV applications can considerably increase through the arrival of future technologies. Worth a mention are home networks and the use of remote controls with tactile feedback.
