Digital Transmission Content Protection Over Internet Protocol

What Does Digital Transmission Content Protection Over Internet Protocol Mean?

The Digital Transmission Content Protection Over Internet Protocol (DTCP-IP) is an IP digital content protection method protecting digital content transmitted over IP networks. It is considered to be a relevant protection technology for short transmission ranges such as those in local area network (LAN) transmissions for home usage. Defined as a type of digital rights management (DRM), various kinds of media adapters can move PC content to other electronic devices.


DTCP-IP is considered a form of media standard. Devices utilizing DTCP-IP can easily transfer protected media. Encrypted connections are utilized between electronics without DTCP-IP, making it impossible to download or view such media.

Techopedia Explains Digital Transmission Content Protection Over Internet Protocol

First identified as 5C, DTCP-IP was developed by five companies: Hitachi, Intel, Matsushita, Sony and Toshiba. Together, those companies formed a collaborative group presenting the protection standard to the Copy Protection Technical Working Group in early 1998. DTCP-IP is proprietary in nature, its members must agree to the protocol’s specified terms. A version of DTCP-IP is available to the public, without any critical and specific information. System developers are working to develop codes enabling sharing of various DRM systems, and sharing content between and among electronic devices. DTCP-IP has become very widely used within devices such as Apple TV. DCTP-IP supports a host of medias such as Wi-Fi, Bluetooth, USB and IP.
