Description

Program reservation method of satellite broadcasting receiver

The present invention relates to a satellite broadcast receiver, and more particularly, to a program reservation method of a satellite broadcast receiver suitable for setting a reservation for various broadcast programs provided to the satellite broadcast receiver and automatically watching at a preset time.

In recent years, the broadcast method using satellites, which is rapidly expanding its use, is a method of providing broadcast signals to a wider area by using satellites (communication satellites) located at an altitude of about tens to hundreds of kilos on the earth's surface. In this satellite broadcasting system, for example, an old band RF signal having a frequency band of 11.7 GHz to 12.0 GHz is used.

To this end, the antenna for satellite broadcasting reception is provided with a low noise blockdown converter for converting a radio frequency (RF) signal of a very high frequency into an intermediate frequency (IF) signal, which is a high frequency RF signal. Is converted into an IF (intermediate frequency) signal in the hundreds to thousands of MHz bands (for example, 950 MHz to 2050 MHz) that can be received by a satellite broadcasting receiver (receiver).

Therefore, in the satellite broadcasting tuner provided in the satellite broadcasting receiver (receiver), the IF signal received through the low noise converter is inputted to tune the channel selected by the user. The satellite broadcasting receiver maximizes channel utilization, image and sound. Along with the improvement of signal quality and the ease of transmitting additional digital service data, the significant improvement of the user interface is a big advantage.

Meanwhile, in satellite broadcasting, a transmission signal of a digital broadcasting signal received from a satellite through a fixed channel to a satellite broadcasting receiver is restored to a transport stream through a process of converting to an intermediate frequency, demodulating, and correcting an error. The stream includes various information such as broadcast signals (video data and audio data) for each channel, an event information table (EIT), a time data table (TDT), and the like.

Then, the program guide information stored in the memory area is used to tune a specific channel selected in a transport stream received through a satellite channel when a specific channel is selected by the user, and also by the user. When the provision of broadcast program information of the channel (i.e., display) is requested, it is composed of a menu screen and displayed on the monitor.

Such a conventional satellite broadcast receiver does not provide a reservation viewing function for a specific broadcast program. If a user sets a reservation for a broadcast program that the user wants to watch in the satellite broadcast receiver, If there is a function to check the broadcast time and automatically switch channels of the satellite broadcast receiver, it will be able to meet the needs of more diverse users.

Accordingly, the present invention has been made in view of the above-mentioned point, and sets a reservation for a specific program among various broadcast programs provided by the satellite broadcasting receiver, and when a reserved program is received, automatically switches to the corresponding channel to reserve the reserved program. An object of the present invention is to provide a program reservation method of a satellite broadcast receiver for viewing.

In order to achieve the above object, the present invention provides a method for reserving a program in a satellite broadcast receiver for receiving broadcast signals for various broadcast programs provided from satellites and storing program information for each channel inserted in the satellite broadcast signals. If a key signal for displaying program information for each channel is input, displaying a program guide screen based on the stored program information for each channel; A second step of storing the reserved program information and turning off the program guide screen when a reservation setting key signal for an arbitrary program among various programs displayed on the program guide screen is input; A third step of continuously checking a broadcasting time corresponding to the reserved program while the general broadcasting mode of the satellite broadcasting receiver is performed; A fourth step of comparing a broadcast channel corresponding to the reserved program with a broadcast channel performing the normal viewing mode when a broadcast time corresponding to the reserved program is detected; As a result of the comparison, if the respective broadcast channels do not match, the method of the program reservation of the satellite broadcast receiver comprising the step of switching the channel of the satellite broadcast receiver to a broadcast channel corresponding to the reserved program.

When the program guide screen for each channel is displayed as shown in the drawing, when the user operates the key input unit 110 again to input a reservation setting key for a specific program, the microcomputer 120 reserves a reservation setting key. Based on the signal, reservation information for the corresponding program is stored in a predetermined area of the memory unit 140.

In addition, a control signal is generated in the OSD unit 170 again to indicate that a reservation is set for a reserved program item among a plurality of program items included in the guide screen, that is, a reservation setting display 210 as shown in FIG. 2B. ) To display.

Subsequently, when the user sets a reservation for another program, the microcomputer 120 repeatedly performs the above-described process. FIG. 3A illustrates a reservation setting process of the satellite broadcasting receiver according to an exemplary embodiment of the present invention. As a flowchart, the series of processes described above with reference to the drawings are described in detail as follows.

During the normal viewing mode or standby mode for displaying a specific broadcast program among various broadcast programs provided from satellites (step 301), when a program guide key signal for displaying program information for each channel is input from the key input unit 110 (step 303), the microcomputer 120 reads program information for each channel stored in the memory unit 140 and displays a program guide screen as shown in FIG. 2A through the OSD unit 170 (step 315).

When the program setting screen for each channel is displayed through the above-described process, when the reservation setting key signal for the specific program is input through the key input unit 110 (step 307), the microcomputer 120 displays the OSD unit. In operation 170, the reservation setting display 210 is added to the reserved program item and displayed (step 309), and information about the reserved program is stored in a predetermined area of the memory unit 140 (step 311).

If a key signal for turning off the guidance screen is input in the state in which the program guidance screen for each channel is displayed through the above-described step 305, a predetermined time elapses without inputting a key signal for performing another specific command. In step 313, the microcomputer 120 turns off the currently displayed program guide screen and switches the overall operation of the satellite broadcasting receiver to the normal viewing mode of the initial step 301 described above (step 315).

On the other hand, when the reservation setting key signal for another program is input while the reserved program information set by the user through the above-described step 311 is stored in the predetermined area of the memory unit 140, the above-described step 307 is performed. If the key signal for turning off the program guide screen displayed on the screen is input or the predetermined time elapses without inputting the key signal for performing another specific command, the process is repeated (step 313). As described above, the program guide screen currently displayed by the microcomputer 120 is turned off and the overall operation of the satellite broadcasting receiver is switched to the normal viewing mode such as the initial stage 301 described above (step 315).

When the reservation for a specific program is set through each process as described above, the microcomputer 120 checks the broadcast time for the corresponding program and automatically receives a broadcast signal for the corresponding program. As a flowchart illustrating a process of performing reservation viewing for the following, it will be described with reference to the accompanying drawings.

After the reservation for a specific program is set through the process as shown in FIG. 3A, when the operation of the satellite broadcasting receiver is performed in the normal viewing mode (step 351), the microcomputer 120 receives the reservation information set in the memory unit 140. By reading (step 353), the broadcast time for the reserved broadcast program is continuously checked.

When the preset time, i.e., the time corresponding to the reserved broadcast program, is reached (step 355), the microcomputer 120 determines whether the currently displayed broadcast channel matches the broadcast channel of the reserved program. If the channel being viewed matches the reserved channel, the broadcast signal of the corresponding channel is continuously displayed through a predetermined signal processing process.

If, as a result of the determination in step 357, the presently viewed broadcast channel does not match the broadcast channel of the reserved program, the microcomputer 120 generates a tuning control signal to the tuner and the demodulator 130. The viewing channel of the satellite broadcasting receiver is switched to a channel corresponding to the reserved channel (step 359), and the broadcast signal for the corresponding program is displayed through a predetermined signal processing process (step 361).

As a result, while the user is watching an arbitrary broadcast channel, when the broadcast time of the reserved program is reached, the viewing channel of the satellite broadcast receiver is automatically switched to the reserved channel.

As described above, according to the present invention, among the various broadcast programs provided by the satellite broadcast receiver, the user can set a reservation for a specific broadcast program desired by the user and automatically watch the corresponding program, thereby improving the overall function of the satellite broadcast receiver.
