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.
