A parallel, nearly simultaneous transmission channel simulates real-time interactive capability from a television station to a viewer in a peripheral device for a television set including an interface at which the television signal can be picked up. The peripheral device is provided with a plug-in device for connecting the 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 the 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.
