(pronounced as separate letters) Short for Digital Transmission Content Protection over Internet Protocol
, a specification for copy protection
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.
