Digital Transmission Content Protection, or DTCP, is a digital rights management (DRM) technology that aims to restrict "digital home" technologies including DVD players and televisions by encrypting interconnections between devices. In theory this allows the content to be distributed through other devices such as personal computers or portable media players, if they also implement the DTCP standards. DTCP has also been referred to as "5C" content protection, a reference to the five companies who created DTCP; Hitachi, Intel, Matsushita, Sony, and Toshiba.
