(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.
