Abstract

Systems and methods are disclosed for providing downstream signals to a plurality of receiver networks. A receiver network (i.e., a networked multimedia system) includes a splitter/isolation module (SIM), a primary set-top terminal (STT), and at least one point of deployment module. The point of deployment module communicates with the primary STT via the SIM over coaxial cable. Accordingly, the point of deployment module and connected television utilize some or all of the features including hardware and software that are included in the primary STT via the networked multimedia system.

Claims

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.

2. The network system of claim 1, wherein the primary STT further includes a storage device for storing the presentations having the second encryption scheme, and wherein the modulated signals includes a stored presentation.

3. The network system of claim 1, wherein the modulator is one of a QAM modulator, a QPSK modulator, a SVSB modulator, and a COFDM modulator.

4. The network system of claim 1, wherein the SIM receives the tuned modulated signal and provides the tuned modulated signal to the point of deployment module, and wherein the SIM receives at least one reverse command signal provided by the point of deployment module and provides the at least one reverse command signal to the primary STT.

5. The network system of claim 4, wherein the upstream signals are transmitted in a plurality of upstream frequencies, and wherein a reverse frequency of the at least one reverse command signal is excluded from the plurality of upstream frequencies.

6. The network system of claim 1, wherein the point of deployment module communicates with the primary STT by transmitting at least one reverse command signal via coaxial cable connected between the SIM and the cable-ready television.

7. The network system of claim 6, wherein the at least one reverse command signal is transmitted in an OOK format.

8. The network system of claim 6, wherein the at least one reverse command signal is transmitted in an FSK format.

9. The network system of claim 6, wherein the POD module receives a signal indicative of the at least one reverse command signal from the cable-ready television, wherein a user initiates the signal.

10. The network system of claim 1, wherein the downstream signals are transmitted in a plurality of downstream frequencies, and wherein the predetermined frequency of the tuned modulated signal is excluded from the plurality of downstream frequencies.

11. The network system of claim 1, wherein the tuned modulated signal is one of a stored presentation, a VOD presentation, an IPG application, an NMS application, and a television channel.

13. A network system for transmitting downstream presentations from a communications system and for transmitting upstream control signals received from devices with the network system, the network system comprising:

a primary set-top terminal (STT) for receiving downstream presentations in a first encryption scheme and for storing selected presentations in a second encryption scheme, and for modulating a selected presentation having the second presentation scheme at a predetermined frequency and for providing the modulated presentation within the network system;

a point of deployment (POD) module coupled to a television, the POD module comprising;
