Abstract
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.

A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical and/or abstract characters represented thereby; and control means for determining the value of analog data, other than the tuning frequency of said television set, relating to the operation of said television set, and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data.
Claim 2
Dependent Claim
95 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical and/or abstract characters represented thereby; and control means for determining the value of analog data, other than the tuning frequency of said television set, relating to the operation of said television set, and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data.
Claim 3
Dependent Claim
122 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical and/or abstract characters represented thereby; and control means for determining the value of analog data relating to the operation of said television set and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data, said control means also causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters indicative of which of said data the user of said television set has last selected to adjust.
Claim 4
Dependent Claim
122 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical and/or abstract characters represented thereby; and control means for determining the value of analog data relating to the operation of said television set and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data, said control means also causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters indicative of which of said data the user of said television set has last selected to adjust.
Claim 5
Dependent Claim
106 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical, and/or abstract characters represented thereby; and control means for determining the value of analog data relating to the operation of said television set and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data, said alphabetical, numerical and/or abstract characters consisting of a number of characters proportional to the value of said analog data.
Claim 6
Dependent Claim
106 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical, and/or abstract characters represented thereby; and control means for determining the value of analog data relating to the operation of said television set and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data, said alphabetical, numerical and/or abstract characters consisting of a number of characters proportional to the value of said analog data.
Claim 7
Dependent Claim
102 words
A television set, comprising: a picture display device for displaying a video picture; character generator means for generating signals representative of alphabetical, numerical and/or abstract characters; said picture display device receiving said signals and displaying the alphabetical, numerical and/or abstract characters represented thereby; and control means for determining the value of analog data relating to the operation of said television set and for causing said character generator means to generate signals representative of alphabetical, numerical and/or abstract characters which indicate said value of said analog data, at least one of said alphabetical, numerical andl/or abstract characters indicating the type of data concerned.
Claim 8
