Abstract
A remote control-digital tuning interfacing system wherein an "on board" receiver at the means to be controlled receives coded transmission from the remote point and demodulates it to produce a digitally coded output which is fed to an "on board" decoder producing the appropriate control voltages to selectively operate electronic switching means. The electronic switching means parallel "on board" push-button operated switches so that a remote control operator can effect, from a remote point, the switching corresponding to that performed at the remote point, thus, only the switching is duplicated and the control complication all resides at the means to be controlled location rendering the system independent of different types of control operation.
Claims3
A system for interfacing a remote control unit with a receiver having a plurality of switches, said system comprising a remote control receiver having input means for receiving a signal encoded with a plurality of function control bits and an extra bit, a plurality of outputs for supplying said function control bits respectively, and an output for supplying said extra bit;
- a plurality of gates having first inputs coupled respectively to said plurality of outputs of said remote control receiver, second inputs, and outputs;
- a decoder having inputs coupled to said gate outputs respectively, and a plurality of outputs;
- a plurality of electronic switches having control inputs coupled to said decoder outputs respectively, and conduction electrodes adapted to be coupled in parallel to said receiver switches;
- and means coupled between said extra bit output means and said second inputs of said gates for ensuring that said function control bits are supplied to said decoder inputs only during the duration of said extra bit.
