Abstract
The present invention aims to address the issue of deploying costly hardware by proposing a content protection layer with an easy distribution capability to clients. The aim is achieved by an network device for descrambling an access controlled audio/video content stream, said network device being configured to be connected to a network router comprises a memory to store a unique address UA specific to the network device, an network input/output interface, a descrambler to descramble the audio/video content stream, and a watermark engine configured to watermark the descrambled audio/video content stream by applying the unique address. A further object of the invention is a method to access scrambled audio/video content stream in a local or roaming mode by a multimedia reception device connected via an IP network to a network router having an IP port connected to the network device.
