Abstract
The Digital transmission content protection (DTCP) specification
defines a cryptographic protocol for protecting audio/video
entertainment content from illegal copying, intercepting
and tampering as it traverses high performance digital
buses, such as the IEEE 1394 standard. DTCP ensures
that the copy protection mechanism is built into Digital
Audio/ Video devices themselves (in addition to Traditional
Encryption). This paper outlines the basic principles
of DTCP including different layers of copy protection
and some implemen-tation aspects.
This paper also provides case studies of typical uses
of content protection in a Digital TV and Digital VCR
implementation. Wipro’s Product solution includes
Hardware and Soft-ware implementation for the Digital
transmission content protection mechanism.
