Digital Transmission Content Protection Over Internet Protocol
(also DTCP-IP)
Digital Transmission Content Protection Over Internet Protocol definition
The Digital Transmission Content Protection over Internet Protocol (DTCP-IP) is a digital rights management (DRM) system designed to control the transmission of content over IP networks. The primary aim of DTCP-IP is to protect high-value content from piracy in domestic environments, such as capturing data being streamed from a set-top box.

How Digital Transmission Content Protection Over Internet Protocol works
DTCP-IP provides a mechanism for controlling the distribution of digital content between devices connected over IP networks. DTCP-IP first encrypts the content, then authenticates and authorizes devices within the network to decrypt it. This setup allows home devices to exchange content without users being able to intercept the data and reproduce it.
DTCP-IP is used to maintain control over intellectual property and adhere to licensing agreements. Moreover, it incorporates mechanisms for managing the flow of content, including features like copy protection and usage restrictions. For instance, content owners can specify whether a particular piece of media can be copied, how many times it can be copied, and whether it can be played on multiple devices simultaneously.
