Claims

[Scope of utility model registration request]

a teletext signal separation unit that separates a teletext signal from a received television broadcast signal, a CPU, a ROM,
a control unit consisting of a RAM and controlling storage, retrieval, and reading of the teletext data output by the separation unit;
A display signal control section converts the teletext data supplied by the control section into a display signal to be displayed on a TV screen, and a remote control signal receiving section reads operation commands output from the remote control operating device or the key input section. In a teletext receiver comprising an input port for outputting a control command to a control section, the teletext data output from the teletext signal separation section is stored in a first predetermined area in the RAM in the order of output from the separation section. , a comparison table consisting of the program number and page number included in the same data and the memory address of the RAM where the same data is stored is stored in a second predetermined area in the RAM, and specified by the key input unit or the remote controller. The R that searches the program number from the comparison table and stores the teletext data of the specified program.
Read the memory address of the first predetermined area in AM,
A teletext receiver characterized by reading teletext data of a designated program using the same memory address.
