Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a satellite broadcast receiver suitable for applying a program search method of a satellite broadcast receiver according to an exemplary embodiment of the present invention, and includes a key input unit 10, a tuner and demodulator 20, and a microcomputer 30. , An MPEG decoder 40, a memory unit 50, and an OSD unit 60.

Referring to the figure, the key input unit 10 is composed of key metrics on the remote control or its own panel to generate a corresponding key signal by the user's operation and provide it to the microcomputer 30. And a function key for searching for a broadcast program and a numeric key for inputting a corresponding time.

The microcomputer 30 generates a control signal for performing a corresponding function based on the key signal from the key input unit 10. For example, the microcomputer 30 tunes and restores a tuning control signal for tuning a broadcast channel selected by a user. It is provided to the grandfather 20, and generates a decoding control signal for decoding the tuned broadcast signal, etc. In particular, on the basis of the input time by reading the broadcast program information for each channel based on the time information input by the user Only broadcast programs are extracted.

Then, the tuner and demodulator 20 tunes the bit stream of the channel corresponding to the tuning control signal of the microcomputer 30 in the bit stream from the satellite received through the antenna (not shown), and then demodulates it and then decodes the MPEG decoder. The MPEG decoder 40 separates and decodes the broadcast signal provided from the tuner and the demodulator 20 into an audio signal and a video signal, and displays it on a screen through a predetermined signal processing process. .

On the other hand, the memory unit 50 stores various program information output from the above-described tuner and demodulator 20 under the control of the microcomputer 30, and outputs the stored program information under the control of the microcomputer 30 again. Done.

In addition, the OSD unit 60 displays the OSD driving control signal and various OSD data provided from the microcomputer 30 on the screen through a predetermined signal processing process. In particular, each channel of the satellite broadcasting receiver is requested by the user. The program information is displayed on a guide screen of a predetermined form.

In the satellite broadcasting receiver configured as described above, when a user operates the key input unit 10 to input a key signal for searching for a broadcast program of a specific time zone, the microcomputer 30 responds to the key signal and the memory unit 50. The OSD data and the OSD driving control signals stored therein are provided to the OSD unit 60.

Accordingly, the OSD unit 60 displays a menu screen according to the program search, that is, a menu screen as shown in FIG. 2, and the user refers to the menu screen displayed on the screen to search and start the search time. Will be entered.

At this time, the microcomputer 30 checks whether the start time and the end time of the date input by the user are set correctly. For example, the program information is stored in the corresponding time zone of the date input by the user. It is determined whether it is included in the program information stored in.

In addition, it is checked whether the start time and the end time that are entered are reasonable. For example, when the search start time is entered as 16:00 and the search end time is entered as 09:00 on the same date, the entered time is A predetermined guidance message (for example, 'time setting is wrong') indicating that something is wrong is superimposed on the currently displayed search menu screen.
