3. DTCP?
[DTCP]
The Digital Transmission Content Protection Specification defines a cryptogrphic
protocol for protecting audio/video entertainment content from unauthorized
copying, intercepting, and tampering as it traverses digital transmission
mechanisms such as a high-performance serial bus that conforms to the IEEE
1394-1995 standard. Only legitimate entertainment content delivered to a source
device via another approved copy protection system (such as the DVD Content
Scrambling System) will be protected by this protection system.
