Abstract
Abstract A Cable Television (CATV) Converter box or computer has a Smart Card connector mounted in a bottom wall thereof. The Converter box includes a case having a top wall, the bottom wall, and four side walls, a main printed circuit (PC) board mounted within the Converter box and parallel to the top and bottom walls thereof, and a Smart Card connector. The Smart Card connector is mounted directly onto the PC board and within a protrusion of the bottom wall of the Converter box. The Smart Card connector defines an opening which is aligned with a first end of a groove defined in the bottom wall of the case for receiving a Smart Card storing a predetermined signal security decrypting algorithm. A second end of the groove is either formed in one of the side walls of the device or in the bottom wall of the case. The Smart Card is installed by inserting the Smart Card in the groove and placing it into contact with the Smart Card connector.
