DTCP-IP

(pronounced as separate letters) Short for Digital Transmission Content Protection over Internet Protocol, a specification for copy protection of copyrighted content that is transferred over digital interfaces in home networks that adhere to IP. Under this specification, digital content can be shared securely between devices in a user s home but not shared with third-parties outside the home network. Using an authentication scheme, DTCP-IP allows the user to designate devices in the home network as trusted destinations that can transfer data back and forth, but DTCP-IP will not allow the content to be transmitted over the Internet to be shared outside of the home network.

DTCP-IP was developed jointly by Intel, Toshiba, Hitachi, Sony, and Panasonic.
