Digital content protection LSI for PC-based digital TV receivers

This paper describes a "digital content protection LSI" that prevents the hacking of PC-based digital TV receivers. Given the wide public knowledge about PC architecture, crackers may gain unauthorized access to PC software. Consequently, many broadcasters and other content holders are concerned that digital broadcast content may be stolen. This situation has curtailed the development of PC-based digital TV receivers for some time. Therefore, we have designed a protection scheme whereby content is protected even in open architecture environments such as the PC environment. This protection has been implemented in the form of a digital content protection LSI. These LSIs will open the way for the continued development of PC-based digital TV receivers.
