Controlling access to broadcast programming
Abstract:
A set top box for a television receiver has a paired viewing card. It is also coupled to a hard disc drive for the recording and storage of received broadcasting. If the viewer has a full subscription, the viewer is able to access and view subscription broadcasting by way of the set top box. If the subscription is no longer paid, different usage rights are associated with the set top box so that, while the set top box can no longer access the subscription broadcasting, the viewer is still able to access and play any previously stored subscription programming.
