[Detailed Description of the Invention] [Technical Field] 1]-1 The present invention relates to a device for displaying characters, symbols, etc. on a video screen of a television receiver, and in particular, the present invention relates to a device for displaying characters, symbols, etc. on a video screen of a television receiver. Concerning displaying.

<Prior Art> In order to view a desired television program, a television receiver generally operates a disc-type or touch-button-type channel selection operation section to broadcast the television program. It is best to tune to the receiving channel that the station has in its broadcasting area. Incidentally, even if the same television broadcast station is broadcast in different areas, the receiving channel numbers may be different. In fact, different television broadcasting stations may have the same reception channel number if they are broadcast in different areas. For this reason, the channel selection operation section of a television receiver generally does not have the station name of the television broadcasting station corresponding to the reception channel number. Therefore, when performing a channel selection operation, the viewer must memorize the received channel number and station name in correspondence with each other in order to view the television program, which is cumbersome.

<Objective> An object of the present invention is to provide a station name display device for a television broadcasting station that eliminates the above-mentioned troubles.

For this purpose, the present invention makes it possible to display at least the station name of a television broadcasting station on the video screen of a television receiver in correspondence with the reception channel number.
