Abstract

A system and method is disclosed for providing DRM in a broadcast environment. In accordance with the embodiment, a DRM system distributes encrypted service keys over the mobile telephone network to a mobile terminal. The mobile terminal receives the encrypted service key and uses it to decrypt encrypted content keys received from a DVB set top box. The decrypted content keys are sent to the set box over local link where they are used to decrypt encrypted broadcast content. A power management technique for mobile receivers is also disclosed that enables the receiver hardware to power off during a portion of the rendering process.
