送受信機。[Scope of Claim for Utility Model Registration] (1) A port that outputs the channel control signal of the received television broadcast, a teletext signal separation unit that separates the teletext signal from the input television broadcast signal, and the CPU, ROM, and RAM. a control unit that controls storage, retrieval, and reading of the teletext data output by the separation unit; and a display signal control unit that converts the teletext data output by the control unit into a display signal to be displayed on a television screen. , a remote control signal receiving section that receives a remote control signal from a remote control operating device, or an input port that reads an operation command output from a key input section and relays it to the control section. Teletext broadcasting of programs whose numbers and program numbers included in teletext data match channel numbers and program numbers pre-stored in the non-volatile RAM provided in the control unit by operating a key input unit or remote controller, and table of contents programs. data to the RAM
A teletext receiver characterized by storing information. (2) When the channel number of the received television broadcast and the program number included in the teletext data are not stored in the nonvolatile RAM, the received teletext data is stored in a second area provided in the RAM. The teletext receiver according to claim (1).
