Abstract: A microcircuit card includes input/output elements (14) for digital data, elements for processing (12) the data and control elements (26). The processing elements (12) include members for transferring digital data (DMA) between the input/output elements (14) and a storage zone (18), and elements for communicating with the control elements (26), control data obtained at the digital data. The control elements (26) control the transfer of the digital data by the transfer elements (DMA) taking into account the control data.

Abstract: A telephone system includes a base station (2), at least one mobile station (3), and a special peripheral device (6) which is adapted to cooperate with a TV set (4) in a hands-free telephone mode and includes audio signal processing means and means (8) for communicating with the base station by radio. The peripheral device has a cord (9) for connection to the TV set (4) via a SCART connector, for using at least the loudspeaker of the TV set in the hands-free telephone mode, and it further includes a microphone (12) provided with an anti-Larson device, and a detector (13) for receiving infrared signals from a special remote control device (5) capable of controlling both the peripheral device (6) itself and the TV set (4).
