Abstract:
A network addressable appliance with digital multimedia recording capabilities has limited access including playback of stored multimedia content upon faulty connection with a service provider network. Upon a connectivity event, the network addressable appliance compares a retrieved hardware address for a connected residential gateway to a stored hardware address for an assigned residential gateway. If the two hardware addresses correspond, the network addressable appliance provides playback to stored multimedia content. The system helps prevent violations of digital rights management rules by restricting access to stored multimedia content while the network addressable appliance is connected to an unauthorized residential gateway. The system provides a user with limited access (i.e. playback) to multimedia content during service provider network outages.
