Embodiment Construction

[0038] In the embodiment of the present invention, only a specific case of its application, that is, a more secure HDCP password storage and generation method on an audio-visual device conforming to the HDCP standard, is described.

[0039] Fig. 1 is a device connection frame diagram with a DVI interface according to an embodiment of the present invention. A DVD player with a DVI interface is connected to a monitor through a DVI cable. DVD players and monitors are HDCP compliant. When playing digital programs with HDCP protection, they must first be authenticated, and then the DVD player encrypts the read content and sends it to the display, and the display decrypts the received content and plays it. The above authentication, encryption and decryption processes all use HDCP passwords.

[0040] Fig. 2 has provided the system frame diagram related to the present invention of the home electronic audio-visual equipment. This system frame diagram includes clock crystal oscillato...
