The general operation of the satellite broadcasting receiver configured as described above is performed during the normal viewing mode in which the user receives a broadcast signal of a specific channel selected by the user and displays it on the screen through a predetermined signal processing process (step 201). When a program guide key signal is input through the key input unit 105 to retrieve information (step 203), the microcomputer 110 reads various types of menu screen information stored in the memory unit 130 and is shown in FIG. 3A. The guide screen mode selection menu as described above is displayed on the screen through the OSD unit 135 (step 205).

In other words, as shown in FIG. 3A, a guide screen mode selection menu for selecting whether to display program information for all channels or to search by program grade is displayed. In this case, the user inputs the key input unit 105. If the operation is selected to search the entire information item or the guide screen mode is not selected for a predetermined time period (step 209), the microcomputer 110 reads program information for all channels stored in the predetermined area of the memory unit 130. By providing to the OSD unit 135, a program guide screen for each channel is displayed as shown in FIG. 4 (step 211).

In the state in which the program information screen for the entire channel is displayed as described above, the user can scroll the screen by manipulating the key input unit 105, so that the user can search for a desired program. If a specific program is selected from (step 213), the microcomputer 110 determines whether the selected program is a program of the current time zone, that is, a broadcast program received by the current satellite broadcast receiver or a program of a future time zone (step 225). .

As a result of the determination, in the case of a program in the future time zone, the microcomputer 110 sets a reservation for the selected program (step 227). In contrast, in the case of a program in the current time zone, the microcomputer 110 blocks the operation of the OSD unit 135. Therefore, the program guide screen for each channel displayed on the current screen is turned off, and the broadcast channel signal corresponding to the selected program is tuned through the tuner and demodulator 115 and displayed through a predetermined signal processing process (step 229). ).
