Abstract:
1. A network system, comprising: a primary set-top terminal (STT) for receiving downstream signals encrypted with a first encryption scheme from a communications network and for selectively storing presentations included in the downstream signals with a second encryption scheme, the primary STT comprising: a tuner system for filtering tuned signals; a decryptor for decrypting the first encryption scheme associated with the filtered tuned signals; when the filtered tuned signals are selected to be stored, an encryptor for encrypting the selected tuned signals with the second encryption scheme; and a modulator for modulating the selected tuned signals having the second encryption scheme to a predetermined frequency and for providing modulated signals within the network system; a point of deployment (POD) module inserted into a cable-ready television, the cableready television coupled to the primary STT, the POD module for receiving the downstream signals in the first encryption scheme, and for requesting and receiving a tuned modulated signal in the second encryption scheme from the primary STT via the cable-ready television; and a splitter/isolation module (SIM) for receiving the downstream signals and for providing the downstream signals to both the primary STT and the POD module, and for receiving upstream signals from the primary STT and the POD module and providing the upstream signals to the communications network.
