Interactive television describes any number of efforts to allow viewers to interact with television content as they view. It is sometime called interactive TV, iTV, idTV or ITV (not to be confused with the British Independent Television network).

Return path

To be truly Interactive, the viewer must be able to alter the viewing experience (eg choose which angle to watch a football match), or return information to the broadcaster. This "return path" or "back channel" can be by telephone, mobile SMS (text messages), or cable. Cable viewers receive their programs via a cable, and in the integrated cable return path enabled platforms, they use the same cable as a return path. Tv Mobile: informazioni sulla Tv Mobile. Satellite viewers (mostly) return information to the broadcaster via their regular telephone lines. They are charged for this service on their regular telephone bill. Interactive TV can also be delivered via a terrestrial aerial (digital terrestrial TV such as 'Freeview' in the UK). In this case, there is often no 'return path' as such - so data cannot be sent back to the broadcaster (so you could not, for instance, vote on a TV show, or order a product sample).
