Abstract
Apparatus for controlling various functions of a television receiver such as the picture and audio responses includes a keyboard with numbered keys which are normally used for selecting channels and a program key. When the program key is pressed, an on-screen character generator is caused to display a numbered list or menu of the various functions to be controlled. Thereafter, a particular function can be selected for control by pressing the correspondingly numbered key. This causes the numbered list or menu of the characteristics of the selected function, e.g., the brightness, contrast, sharpness, color level and color tint of the picture, to be displayed. Thereafter a particular characteristic can be selected for control by pressing the correspondingly numbered key.
