In the present invention, a process of searching for a broadcast schedule (TV) of the present invention includes a first process of recognizing whether a broadcast program schedule search setting key is input, and reads the teletext data for each broadcaster if the broadcast program schedule setting key is input. A second process of searching for a page with a broadcast program schedule by using page information including broadcast schedule information stored in the memory; and broadcast schedule information data of a page with a broadcast program schedule found in the second process. After storing in the program schedule data, the third process reads the current time data from the stored program schedule data, and reads the program broadcast time data from the program schedule data stored in the memory and compares the current time data with the current time data of the third process. Be in program air time Reading the stored program data in memory and will be written with the fourth process in which the display on the screen.

If the broadcasting program schedule search setting key is inputted as the first process recognition result, it is determined whether the broadcasting schedule is displayed on the screen, and if the broadcasting schedule is displayed on the screen, the next broadcasting program schedule of the displayed program is displayed. Including the process to be displayed on.

Referring to the accompanying drawings, the operation process and the effect of the broadcast schedule (SCHEDULE) search method of the present invention TV will be described as follows.

FIG. 3 is a block diagram of a device for a broadcast schedule discovery method of the present invention, and FIG. 4 is a flowchart showing an embodiment of the process of the present invention.
