METHOD FOR CONTROLLING PROGRAM GUIDE DISPLAY BY USING ONE DIGITAL TUNER AND DIGITAL BROADCASTING RECEIVING DEVICE THEREFOR, CAPABLE OF QUICKLY SHOWING BROADCASTING INFORMATION WHILE MAINTAINING EXACT INFORMATION ON DESIRED CHANNEL ONLY

摘要

PURPOSE: A method for controlling a program guide display by using one digital tuner is provided to tune a channel whenever the specific channel is selected among EPG(Electronics Program Guide) information on displayed channels, and to update the corresponding EPG information, thereby quickly showing broadcasting information while maintaining exact information on a desired channel. CONSTITUTION: A system receives a broadcasting signal from a set top box or a satellite broadcasting TV(410), and checks whether an EPG service is requested(420). If so, the system checks whether EPG information of N channels are prestored(430). If so, the system tunes a currently displayed channel to extract corresponding EPG broadcasting information(440), and displays EPG information on the extracted current channel and (N-1) prestored channels on a screen(460). The system checks whether a cursor signal for selecting EPG information on other channel is inputted(470). If so, the system controls a program guide display until an EPG mode is terminated(480).
