Method for supporting user interaction in interactive TV and radio programs. The method enables a new way to implement the interaction, as well as new types of content services. For example, a viewer may obtain a picture of his/her favourite actor as follows: the viewer presses a key of a remote control when the favourite actor is shown on a TV-receiver, the TV-receiver sends a time code to the viewer's mobile phone, the viewer transmits the time code to a still image service, and the service sends the still image of the favourite actor in a MMS message to the viewer. The method is based on the idea that each piece of a broadcast can be mapped to a code, such as a time code. This way a TV-viewer can interact with a program pointing to any piece of the broadcast by using the time code.
