Abstract
The present invention relates to a television set which includes a picture display device, an alpha numerical character generating circuit connected to said device, a control device, means for determining analogue data relating to the operation of the set, such as volume, brightness and color, and means for displaying on said display device a combination of alpha numerical characters, supplied by said character generating device, indicating the values of said analogue data. A control keyboard has six keys 'V+', 'V-', 'L+', 'L-', 'C+' and 'C-'. The output of the keyboard is connected to a processing unit which is connected via a digital to analogue converter and switch to an alpha numerical character generator which is connected to a picture display device. When one of the six keys is pressed a combination of signals proportional to the analogue signal level of volume, brightness and color (V, L, C) is displayed on the picture display device. If one of the + keys is pressed, the corresponding analogue level is increased by 1/64 of maximum value, while a similar decrease is obtained by pressing one of the - keys.
