ABSTRACT:
A secure video content processor ("SVCP") which receives encrypted digital video information and converts it into analog information for a monitor while preventing unauthorized access to the intermediate unencrypted digital data. The SVCP uses hardware envelopes to prevent unauthorized access to the decrypted digital stream. When a need arises to transmit digital data outside the hardware envelope, the digital data is encrypted and then decrypted when it re-enters a hardware protected section of circuitry.
