The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings.

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 broadcasting receiver suitable for performing a search method of a satellite broadcasting guide program according to the present invention, and includes a key input unit 10, a tuner and a demodulator 20, a demultiplexer 30, and a microcomputer ( 40), a memory unit 50, and an OSD unit 60.

The key input unit 10 is composed of key metrics on the remote controller or its own panel to generate a corresponding key signal to the microcomputer 40 by a user's operation, and the microcomputer 40 is provided from the key input unit 10. Based on the key signal, a control signal for performing a corresponding function, a tuning control signal for tuning a broadcast channel, and a control signal for driving the OSD unit 60 are generated.

Then, the tuner and demodulator 20 tunes the bitstream of the channel corresponding to the tuning control signal of the microcomputer 40 in the bitstream from the satellite received through the antenna (not shown), and then demodulates it and demultiplexes it. It provides to the part 30.

The demultiplexer 30 separates a broadcast signal provided from the tuner and the demodulator 20 into an audio signal, a video signal, and various program information, and then displays the audio signal and the video signal through a predetermined signal processing process. The program information is provided to the microcomputer 40.

The memory unit 50 stores various program information and various guide screen formats which are decoded and output from the demultiplexer 30 described above by the control of the microcomputer 40, and are again stored under the control of the microcomputer 40. Print program information.

In the satellite broadcast receiver configured as described above, a user operates the key input unit 10 to display broadcast program information for a specific channel, which is preferred by a user, among various channels received by the satellite broadcast receiver. In response to the input, the microcomputer 40 displays a menu screen as shown in FIG. 2A through the OSD unit 60 in response to the key signal.

Accordingly, the user inputs a specific channel that he or she prefers by referring to the menu screen, and the inputted preference channel is configured to enable a plurality of inputs by the user.

When the user inputs his or her favorite channel, the microcomputer 40 is a program corresponding to the channel input by the user among the program information after the current time for the various channels of the satellite broadcasting receiver stored in the memory unit 50. Only the information is extracted to display the program guide screen for each channel as shown in FIG. 2B through the OSD unit 60.

At this time, the displayed program guide screen includes the channel name and the broadcast time selected by the user, and the program title and the type of the program as shown in the drawing, and thus includes detailed information on each program of the channel selected by the user.
