CA 2515410

The aim of the invention is to create an optional, parallel, and nearly simultaneous transmission channel simulating real-time interactive capability from a television station to a viewer in a peripheral device for a television set comprising an interface at which the television signal can be picked up. Said aim is achieved by providing the peripheral device with a plug-in device for connecting said peripheral device to the interface of the television set or an additional interface that is connected to the television set. At least one portion of the television signal applied to said one interface or the additional interface is processed by a processing device of the peripheral device while the data supplied by the processing device is transmitted to a receiver unit via a transmitter unit of the peripheral device.

L'invention concerne un dispositif périphérique pour appareil de télévision qui comporte une interface au niveau de laquelle le signal de télévision peut être prélevé. Avec ce dispositif on obtient un canal de transmission optionnel, parallèle et presque simultané allant de l'émetteur de télévision à un téléspectateur, qui simule une capacité de dialogue en temps réel par le fait que ce dispositif périphérique comporte un dispositif enfichable permettant son raccordement à l'interface de l'appareil de télévision ou à une interface correspondante d'un autre dispositif périphérique raccordé à l'appareil de télévision. Au moins une partie du signal de télévision appliqué à l'une ou l'autre interface est traitée par un dispositif de traitement du dispositif périphérique, et les données délivrées par le dispositif de traitement sont transmises à un dispositif récepteur par l'intermédiaire d'un dispositif de transmission du dispositif périphérique..
