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 method of displaying a guide screen of a satellite broadcast receiver suitable for separately configuring and displaying a program guide screen for a channel that a user prefers in a satellite broadcast receiver. .

As is well known, satellite broadcasting is capable of receiving broadcast signals from ground stations (broadcasting earth stations) using broadcast satellites in a stationary orbit about 36,000 kilometers above the equator, and receiving them directly from the satellite receiving antennas in each home. The broadcasting system is a broadcasting system in which the selection range of information is greatly expanded compared to the conventional terrestrial or cable broadcasting system.

The satellite broadcast receiver used for such a satellite broadcast receives a bitstream provided from a satellite, processes a broadcast signal of a selected channel, and then provides it to a display device (for example, a TV).

In this case, various information such as broadcast signals (image data and audio data), EIT (event information table), and time data table (TDT) for each channel are included in the bit stream provided from the satellite. In the general satellite broadcasting receiver receiving, the user can control the operation of the satellite broadcasting receiver by using his or her ID and watch the broadcasting program.

In addition, a general satellite broadcast receiver is provided with various menu screens for displaying such various information. Among such menu screens, a broadcast program guide screen for guiding a broadcast program received in each channel is included.

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 first memory unit 50 stores various program information and various guide screen formats decoded and output from the demultiplexer 30 described above by the control of the microcomputer 40, and the second memory unit 55 stores the A plurality of user IDs registered in the satellite broadcasting receiver and information on a preferred channel set by each user are received and stored from the microcomputer 40.

Referring to the drawings in detail, in the satellite broadcast receiver configured as described above, the user accesses the satellite broadcast receiver using his or her family ID, which is a shared viewing ID, and then watches the broadcast program.

During the normal viewing mode of the satellite broadcasting receiver in which the broadcast signal of the channel selected by the user is displayed through the above-described process, the user operates the key input unit 10 to set the channel of his or her preferred channel. When the channel setting key signal is inputted, the microcomputer 40 displays a menu screen of a predetermined type for channel setting through the OSD unit 60 in response to the channel setting key signal.

Then, when the user operates the key input unit 10 to set one or more preferred channels, the microcomputer 40 inserts information about each channel set at this time into the currently connected user ID information. 2 is stored in the memory unit 40. This preference channel setting process is possible only when the user ID currently connected to the satellite broadcasting receiver is not a family ID which is a joint viewing ID.

In other words, it is possible to set the preferred channel as described above only when the user is connected to the satellite broadcast receiver using his personal ID in the initial stage after the satellite broadcast receiver is turned on.

As a result, each user turns on the satellite broadcasting receiver using his or her ID and then sets his / her preferred channel through the above-described process. Under the control of 40, it is stored in the second memory unit 55.

FIG. 2 is a flowchart illustrating a process of setting a preferred channel for each user of another satellite broadcasting receiver according to a preferred embodiment of the present invention. Referring to FIG.

During the normal viewing mode in which the operation of the satellite broadcasting receiver displays the broadcast signal of the channel on a monitor (not shown) through a predetermined signal processing process (step 201), the user manipulates the key input unit 10 to select a specific channel that the user prefers. When the preferred channel setting key signal for setting the signal is input (step 203), the microcomputer 40 uses the user ID inputted when the initial satellite broadcasting receiver is powered on. The ID is detected (step 205).

If the detected user is not an ID assigned to each user in the satellite broadcasting receiver, but is a family ID that is a joint viewing ID (step 207), the user's preference channel setting is controlled by the microcomputer 40. A notification message (for example, 'no user ID has been entered') indicating that the status is impossible is displayed (step 209).

On the other hand, if the user ID detected in the above step 205 is not a family ID, a menu screen of a predetermined type for setting a preferred channel under the control of the microcomputer 40 is displayed through the OSD unit 60 ( Step 211), when the user manipulates the key input unit 10 to input a favorite broadcast channel, each broadcast channel input by the user under the control of the microcomputer 40 is the second memory unit 55. Is inserted into the corresponding user ID information and stored (step 213).

In addition, when the input process for the specific channel preferred by the user is ended through the above-described process, the microcomputer 40 turns off the menu screen displayed in the above-described step 211 and generalizes the operation of the satellite broadcasting receiver. The watch mode is switched to (step 215).

As a result, each user of the satellite broadcasting receiver establishes each broadcasting channel preferred by the user through the above-described process, and information about the preferred channel of each user set by the microcomputer 40 is set by the second memory. It is inserted and stored in each user ID information registered in the unit 55.

On the other hand, after the channel information preferred by each user is stored through the above-described process, when the user inputs a program guide key signal for displaying the program guide screen for each channel, the microcomputer 40 is currently connected. After determining the user ID, that is, the user ID input in the initial stage, the second memory unit 55 is read again to determine whether a channel preferred by the user is set.

In this case, when the preferred channel for the corresponding user is set, the microcomputer 40 reads only the program information of the channel preferred by the user from among the broadcast program information for each channel pre-stored in the first memory unit 50 and the OSD. By providing to the unit 60, a program guide screen for one or more channels preferred by the user is displayed.

FIG. 3 is a flowchart illustrating a process of displaying a guide screen of a satellite broadcast receiver according to an exemplary embodiment of the present invention. Referring to FIG.

With the preferred channels for the plurality of users registered in the satellite broadcasting receiver set and stored in the second memory unit 55 (step 301), the user refers to the program information for each channel received by the satellite broadcasting receiver. When the program guide screen key signal is input (step 303), the microcomputer 40 reads ID information of the currently connected user among the plurality of user ID information stored in the second memory unit 55 (step 305). It is detected whether a preferred channel for the user is preset (step 307).

When the preferred channel for the corresponding user ID is set as a result of the detection in step 307 described above, only the program information for the set channel is extracted from the program information for each channel previously stored in the first memory unit 50. (Step 309), the program information on the extracted channel is provided to the OSD unit 60, and the program guide screen for each channel that the user prefers is displayed (step 311).

On the other hand, on the contrary, if the preferred channel for the corresponding user ID is not set or the currently connected user ID is a family ID, the program guide for all channels received by the satellite broadcasting receiver is detected. The screen is displayed (step 313).

As a result, each user registered in the satellite broadcasting receiver may refer to a program guide screen configured only with program information about the corresponding channel by presetting a channel of his or her preference.

As described above, according to the present invention, it is possible to provide convenience for the user's program selection by extracting only program information of a specific channel preferred by the user among various broadcast channels of the satellite broadcast receiver and displaying detailed information on each program. There is an effect, and accordingly there is an effect that can satisfy the needs of various users.
