Abstract

A home content distribution solution that provides distribution capabilities between a Home Media Server (HMS) and remote units, such as a thin Client stand-alone box or an existing legacy digital set-top box (STB). The invention permits combined video and data home networking while leveraging the numbers of already deployed digital set-top boxes. Embodiments of the system and methods are employed to distribute content to a set-top box connected to a home distribution network, which preferably includes a home media server connected to the home distribution network; a reflector, and; an entry point device having entry terminal for connection to an external cable network, a first output terminal for connection to the home distribution network and a second output terminal for connection to the reflector. Content is typically obtained from both the home media server and the cable network and distributed over the home distribution network. The content obtained from both the home media server and the cable network is displayable by an analog television connected to the set-top box.

Claims

1. A system for distributing content to a set-top box connected to a home distribution network, the system comprising:

a home media server connected to said home distribution network;

a reflector; and

an entry point device having entry terminal for connection to a cable network, a first output terminal for connection to said home distribution network and a second output terminal for connection to said reflector,

wherein said content is sourced from both said home media server and said cable network,

wherein said content sourced from both said home media server and said cable network, is distributed over said home distribution network, and

wherein said content sourced from both said home media server and said cable network, is playable by said set-top box.

2. The system of claim 1, wherein said home media server communicates commands with said set-top box over said home distribution network using a command channel, and wherein said command channel uses the reverse data band.

3. The system of claim 1, wherein content from said home media server is carried over said home distribution network within a first predetermined frequency band.

4. The system of claim 1, wherein content from said cable network is carried over said home distribution network within a second predetermined frequency band.

5. The system of claim 1, wherein said home media server is controlled by a home media server control signal from said set-top box, and wherein said home media server control signal is carried over said home distribution network within a third predetermined frequency band.

6. The system of claim 1, wherein the home media server controls said reflector using a reflector control signal carried within a fourth predetermined frequency band.

7. The system of claim 1, wherein said entry point device is a passive entry point comprising a low pass filter connected to said entry terminal and a directional coupler connected between said low pass filter and said first and second output terminals.

8. The system of claim 1, wherein said reflector is an active reflector and said active reflector comprises:

a reflector input terminal;

a reflector diplexer having a first diplexer output and a first diplexer input and a second diplexer input connected to said reflector input terminal;

a reflector RF section having a first RF input connected to said first diplexer output, a second RF input, a first RF output connected to said first diplexer input, and a second RF output; and

a SAW filter having a SAW input connected to said second RF section output and a SAW output connected to said second RF section input,

wherein said active reflector receives signals in a first band and reflects them in a second band having a lower frequency than said first band.

9. The system of claim 8, wherein said RF section further comprises an FSK receiver and control unit connected to said second RF output.

10. The system of claim 1, wherein said home media server comprises:

a HMS diplexer having a first HMS diplexer input, a first HMS diplexer output and a second HMS diplexer input connected to said home media server input;

an HMS RF section having a first HMS RF section input connected to said HMS diplexer output, two second HMS RF section inputs, a first HMS RF section output connected to said HMS diplexer input, and a second HMS RF section output; and

an HMS signal processor having a first HMS signal processor input connected to said second HMS RF section output; and

two HMS signal processor outputs, a respective one of said two HMS signal processor outputs connected to a respective one of said two second HMS RF section inputs.

11. The system of claim 1, wherein said home media server communicates with a demarcation point unit.

12. The system of claim 1, wherein the entry point device comprises a demarcation point unit.

13. A method for distributing content from a cable network and a home media server to a set-top box connected to a home distribution network, the method comprising the steps of:

passing content carried by a first predetermined frequency band from said cable network to said set-top box over said home distribution network;

passing control signals carried by a second predetermined frequency band from said set-top box to said home media server over said home distribution network; and

passing content carried by a third predetermined frequency band from said home media server to said set-top box over said home distribution network.

14. The method of claim 13, wherein said content is sent from said home media server to said set-top box in response to said control signals sent from said set-top box to said home media server.
