First Claim
1. A television receiver program-presetting system for displaying items of program information on the face of a television receiver Braun tube, said system comprising:
- a. means for supplying items of program information;
b. memory means for storing each of said items of program information in a designated address;
c. means for designating the instantaneous vertical position on said Braun tube being scanned by said television receiver;
d. address encoder means for generating a plurality of unique display region signals in response to said vertical position, each of said display region signals representing one area on the face of said Braun tube;
e. means for removing an item of program information from an address of said memory means corresponding to one of said display region signals;
f. means for producing signals denoting character patterns corresponding to said removed item of program information; and

Abstract
A television receiving program-presetting system comprises means for storing receiving program information in a specified address of a memory; a circuit for defining a vertical address position on a Braun tube screen by counting horizontal synchronizing pulses; a circuit for designating a horizontal address position on the Braun tube screen by counting clock pulses having a higher frequency than the horizontal synchronizing pulses; means for successively producing address information designating the addresses of the memory upon receipt of the outputs from at least the vertical address position defining circuit; means for supplying the address information to the memory and successively reading out the stored program information therefrom; a circuit for generating signals denoting character patterns corresponding to the program information thus read out; means for displaying the character patterns in the form of program information at that address position on the Braun tube screen which is designated by an output signal from the circuit for defining at least a vertical address position on the Braun tube screen; and means for temporarily shutting off the supply of an image signal to the Braun tube while the program information is displayed thereon.
