Abstract

A satellite TV system including a plurality of channel strips each including a tuner and a modulator matched to each other. The tuner selects the particular satellite signal and the modulator selects the particular channel on the TV. Both tuner and modulator circuits include a divide-by-two component which permits use of lower cost electronic components while producing high quality TV pictures or other outputs. Each channel strip is in the form of a plug-in module. A control box houses all of the plug-in channel strips and the other electronics.

Claims

1. A satellite TV system including a plurality of channel strips, said system being adapted to supply a plurality of TVs comprising a dish antenna for receiving satellite TV signals, said plurality of channel strips receiving input signals including individual ones of said satellite TV signals, a control computer, a signal distribution and control matrix between said plurality of channel strips and said plurality of TVs supplied by the system, each of said strips comprising a series array of a tuner circuit and a modulator circuit, said tuner and modulator circuits being matched to each other, said tuner circuit being matched to the input of said channel strip and said modulator circuit being matched to the output of said channel strip, a control box, each said channel strip being made in the form of a prefabricated module, said modules and said control box including means to mount said channel trips in said box in an easily removable plug-in manner, and said computer controlling said channel strips to match a particular input signal to a particular pre-tuned TV channel frequency on a particular TV.

2. The system of claim 1, and means to remotely control said computer.

3. The system of claim 2, and display means associated with said remote control means, said display means including an array of LEDs to indicate which TVs of said plurality are blocked from receiving which input signals.

4. The system of claim 1, and means to input signals other than said satellite signals including local TV signals, VCR signals, video camera signals, data, and the like for distribution to said TVs.

5. The system of claim 1, and said matrix including switch means controlled by said computer to block selected ones of said TVs from receiving selected ones of said input signals.

6. The system of claim 1, and timer means associated with said computer.

7. The system of claim 1, and motor means to control the position of said dish antenna, and said computer controlling said motor means.

8. The system of claim 1, and battery back-up means associated with said computer for retaining the computer programming in the event of a power failure.

9. The system of claim 1, each of said channel strip tuner and modulator circuits also being matched under the control of said computer to a particular incoming satellite signal and said modulator also being matched under the control of said computer to a particular pre-tuned TV channel frequency.

10. The system of claim 1, each of said channel strips being made in the form of a said prefabricated module, and means to mount said control computer in said control box.
