ABSTRACT:
A system and corresponding method are provided for selecting one of a plurality of simultaneously received encrypted direct broadcast satellite (DBS) signals for decryption and viewing. A converter box or decrypting device is provided with a plurality of different decrypting smart cards, all of which are simultaneously inserted in the converter box. The user or viewer scans the received signals and selects one for viewing. The different decrypting algorithms of the different smart cards respectively correspond to the different encryptions of the received DBS signals so that the selected encrypted signal is decrypted by the appropriate and corresponding decrypting smart card and subsequently decompressed and viewed.
