How to Display the Guide Screen of a Satellite Broadcast Receiver

The present invention relates to a satellite broadcast receiver, and more particularly, to a channel setting method of a satellite broadcast receiver suitable for setting and watching only a desired channel among a plurality of broadcast channels provided at a satellite broadcast receiver.

In recent years, the broadcast method using satellites, which is rapidly expanding in use, is a method of providing a broadcast signal to a wider area by using a satellite (communication satellite) located at an altitude of about tens to hundreds of kilos on the surface of the earth. 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, various signals such as broadcast signals (video data and audio data), event information table (EIT), and time data table (TDT) for each channel are included in a satellite signal provided from a satellite, that is, a bit stream.

Accordingly, a general satellite broadcast receiver is provided with various menu screens for displaying such various information. Among the menu screens, a broadcast program for guiding information about each channel where a broadcast signal is received and a broadcast program received for each channel is provided. A guidance screen is included.

FIG. 4 is a diagram illustrating an example of a program guide screen for each channel provided by a conventional satellite broadcast receiver. When a user requests program information for each channel through a key input unit, FIG. 4 is inserted into a satellite broadcast signal. Program information for each channel is sequentially displayed for each time zone as shown in the figure.

However, since the program information for all channels received by the satellite broadcasting receiver is not displayed on the displayed guide screen, the user scrolls the screen left, right, up, or down by using a key input means. The user searches for the desired channel or broadcast program.

That is, while the size of the program guide screen for each channel provided by the satellite broadcast receiver is limited, the number of broadcast channels continues to increase, so the user repeats the cumbersome key manipulation process while the program guide screen is displayed. There is an inconvenience of having to select a program of the desired channel.

Accordingly, the present invention has been made in view of the foregoing, and provides a method for displaying a guide screen of a satellite broadcast receiver capable of displaying and configuring a broadcast channel displayed on a program guide screen of a satellite broadcast receiver only as channels desired by a user. The purpose is.

In order to achieve the above object, the present invention provides a satellite broadcast receiver for receiving a broadcast signal for a plurality of satellite broadcast channels provided through a satellite, pre-store broadcast program information for each channel extracted from the broadcast signal, and display the same. In the method for displaying a program guide screen, a channel including the plurality of channels when a key signal for deleting an arbitrary channel among a plurality of broadcast channels for the program guide screen is input during the normal viewing mode of the satellite broadcasting receiver. A first step of displaying a deletion menu screen; If at least one or more channels of the displayed plurality of channel numbers are selected, deleting each of the selected channels to update channel information registered in the satellite broadcasting receiver, and turning off the channel deletion menu screen; A third step of reading channel information of the updated satellite broadcasting receiver when a key signal for displaying program information for each channel is input during the normal viewing mode of the satellite broadcasting receiver; And a fourth step of extracting and displaying program information corresponding to each read channel from the previously stored program information for each channel.
