Abstract

Signals from a remote control transducer are decoded in a television receiver to cause display of characters in a predetermined color on a color display tube when a particular function control mode such as hue or saturation control is remotely selected.

Claims

1. A color function display system, comprising:

means for generating coded signals representative of data and representative of a color indicating a particular function enabled mode to be displayed on a color display tube;

character generator means coupled to said means for generating coded signals and responsive to said coded signals for generating video signals representative of said data;

enabling means coupled to said means for generating coded signals and responsive to said coded signals for generating a color enabling signal; and

color video signal generating means coupled to said character generator means and said enabling means and responsive to said video signals representative of said data and responsive to said color enabling signal for producing color representative signals for displaying said data in said color representative of said function enabled mode.

2. A color function display system according to claim 1 wherein said means for generating coded signals include remote transducer means for transmitting selected frequencies representative of particular data and particular functions to be enabled and receiving means for converting said selected frequencies to said coded signals in digital form for activating said character generator means and said enabling means, said enabling means producing analog signals in response to said coded signals in digital form for activating said color video signal generating means.

3. A color function display system according to claim 2 wherein said enabling means in response to said digital signals selectively activates said color video signal generating means for producing said displayed data in a selected one of a plurality of colors representative of a particular function enabled mode selected at said remote transducer.

4. A color function display system according to claim 3 wherein said color video signal generating means, in response to said analog signals, selectively controls one of a plurality of functions including picture color saturation or picture hue.
