Abstract: An interactive arborescent architecture teledistribution network includes an exchange controlling the transmission of television programs, images and sound programs and a wide band source for transmitting all these programs. A user differentiating circuit box is used as well as a circuit to interrogate the user differentiating circuit box, a circuit to transmit a program request from the user for the exchange once the box of the user has been addressed by the exchange, circuits in the exchange for generating a validation signal in response to the request, and circuits disposed in the user differentiating circuit box so as to select a program from all the programs transmitted according to the validation signal. The user differentiating circuit box is preferably disposed on the arborescent architecture between the exchange and the television receiver of the user.
