Abstract

A multi-channel video and data unit comprises a splitter to split a combined data and video service signal into a data service signal and at least one video service signal. A modem and data networking module generates a data networking signal based on the data service signal. A user-initiated video selection is received by each of a plurality of remote control devices. Each of a plurality of video processing modules is responsive to a corresponding one of the remote controls to process the video service signal based on the user-initiated video selection and to generate a corresponding television signal based thereon. Each of a plurality of combiners combines the television signal from a corresponding one of the video processing modules with the data networking signal to form a corresponding combined television and data networking signal.

Claims

1. An apparatus comprising:

a splitter to split a combined data and video service signal into a data service signal and at least one video service signal;

a modem and data networking module to generate a data networking signal based on the data service signal;

a plurality of remote control devices each to receive a user-initiated video selection;

a plurality of video processing modules each responsive to a corresponding one of the remote controls to process the video service signal based on the user-initiated video selection and to generate a corresponding television signal based thereon; and

a plurality of combiners each to combine the television signal from a corresponding one of the video processing modules with the data networking signal from the modem and networking module to form a corresponding combined television and data networking signal.

2. The apparatus of claim 1 wherein the splitter comprises a diplex filter.

3. The apparatus of claim 1 wherein the combined television and data networking signal has a lower frequency band for the data networking signal, and an upper frequency band for the television signal.

4. The apparatus of claim 3 wherein the lower frequency band is below 25 MHz.

5. The apparatus of claim 1 wherein the data networking signal is toned for communication over a 75-Ohm coaxial cable.

6. The apparatus of claim 1 further comprising:

at least one card-receiving slot to receive an additional at least one video processing module.

7. The apparatus of claim 1 wherein the remote control devices provide a video recording selection and a video playback selection, wherein the apparatus further comprises a storage device to store video from the video service signal based on the video recording selection and to playback the video based on the video playback selection, wherein each of the video processing modules is responsive to its corresponding one of the remote controls to process the video from the storage device based on the video playback selection and to generate a corresponding television signal based thereon.

8. The apparatus of claim 1 wherein the combined data and video service signal is provided by a head end of a cable television system.

9. The apparatus of claim 8 wherein the modem and data networking module comprises a cable modem.

10. An apparatus comprising:

a diplex filter to split a combined data and video service signal provided by a head end of a cable television system into a data service signal and at least one video service signal;

a modem and data networking module to generate a data networking signal based on the data service signal;

a plurality of remote control devices each to receive a user-initiated video selection;

a plurality of video processing modules each responsive to a corresponding one of the remote controls to process the video service signal based on the user-initiated video selection and to generate a corresponding television signal based thereon;

at least one card-receiving slot to receive an additional at least one video processing module; and

a plurality of combiners each to combine the television signal from a corresponding one of the video processing modules with the data networking signal from the modem and networking module to form a corresponding combined television and data networking signal;

wherein the combined television and data networking signal has a lower frequency band for the data networking signal, and an upper frequency band for the television signal; and

wherein the data networking signal is toned for communication over a 75-Ohm coaxial cable.

11. An apparatus comprising:

a splitter to split a combined data and video service signal into a data service signal and at least one video service signal;

a modem to demodulate the data service signal;

a data networking module responsive to the modem to generate a data networking signal based on the demodulated data service signal;

a plurality of remote control devices each to receive a user-initiated video selection; and

a plurality of video processing modules each responsive to a corresponding one of the remote controls to process the video service signal based on the user-initiated video selection and to generate a corresponding television signal based thereon.

12. The apparatus of claim 11 wherein the splitter comprises a diplex filter.

13. The apparatus of claim 11 further comprising:

at least one card-receiving slot to receive an additional at least one video processing module.

14. The apparatus of claim 11 wherein the remote control devices provide a video recording selection and a video playback selection, wherein the apparatus further comprises a storage device to store video from the video service signal based on the video recording selection and to playback the video based on the video playback selection, wherein each of the video processing modules is responsive to its corresponding one of the remote controls to process the video from the storage device based on the video playback selection and to generate a corresponding television signal based thereon.

15. The apparatus of claim 11 wherein the combined data and video service signal is provided by a head end of a cable television system.

16. The apparatus of claim 15 wherein the modem comprises a cable modem.
