Abstract
The digital home network handles a plurality of devices using different media such as Ethernet, General Packet Radio Service, Wi-Fi, and USB. DRM/CAS protects content until it reaches the home. The location of this acquisition point within the home network is a tricky issue, known as CA-to-DRM. Content transferred from the acquisition point to other devices needs protection. The first approach is to use link encryption. This is usually done by DTCP. DVB-CPCM proposes a global approach that encompasses the entire home network. Content always stays scrambled within the home network. Descrambling only occurs at rendering and exporting points.
