How to Scroll the Guide Screen of a Satellite Broadcast Receiver

The present invention relates to a satellite broadcast receiver, and more particularly, to a method of scrolling a guide screen of a satellite broadcast receiver suitable for processing a key signal input by a user more efficiently than to control the overall operation of the satellite broadcast receiver. will be.

Satellite broadcasting is a broadcasting system that can receive a broadcast signal from a ground station (broadcasting earth station) using a broadcasting satellite and receive it directly from a satellite receiving antenna in each home. Receives a digital broadcast signal, extracts a broadcast signal of a selected channel among broadcast signals received by a transport demultiplexor, and decodes the extracted broadcast signal using a MPEG (Motion Picture Expert Group) method to provide a display device. Is configured to.

In addition, unlike the conventional terrestrial broadcasting, such satellite broadcasting system provides program information for each channel, and the user can more conveniently select a desired broadcasting program or channel by referring to a program guide screen for each channel. . FIG. 4 is a diagram illustrating an example of a program guide screen provided by the conventional satellite broadcast receiver. When a user requests a program guide screen using a key input unit of the satellite broadcast receiver, FIG. As described above, program information for each channel is sequentially displayed for each time zone, and the user can again search for a desired program by scrolling the screen left / right or up / down using a key input means.

Looking at the process of scrolling the guide screen according to the user's key input in the state that the program guide screen for each channel provided by the conventional satellite broadcasting receiver is displayed, the user is displayed in the guide screen using the key input means (401) When the key signal for moving the c) to a previous time zone, that is, to the left, is input, the control unit provided in the satellite broadcasting receiver reads and guides program information of a time zone or channel corresponding to the input key signal from all previously stored program information. The entire screen will be displayed again.

As a result, in the conventional general satellite broadcasting receiver, when the user scrolls the screen by using a key input means while the program guide screen for each channel is displayed, the time zone corresponding to the key signal input from the pre-stored program information for each channel is stored. The program information is read, the program guide screen displayed on the current screen is turned off, and the program guide screen for each channel is displayed again based on the read information.

If the screen scroll key signal is repeatedly inputted very quickly in succession, since the above-described operation process must be repeated as many times as the input key signal, the overall graphic processing speed is reduced, and thus the guide screen scroll speed is reduced. There is a problem that proceeds very slowly compared to the input key signal.

Accordingly, the present invention is to solve the above-described problems of the prior art, it is determined by repeating the content of the key signal repeatedly input to scroll the screen while the program guide screen for each channel of the satellite broadcast receiver is repeated An object of the present invention is to provide a method of scrolling a guide screen of a satellite broadcast receiver, which can process a guide screen scroll more quickly while simplifying an internal process.

In order to achieve the above object, the present invention, the satellite broadcast receiver to receive the satellite broadcast signal provided through the satellite, and scrolls the guide screen in the satellite broadcast receiver to configure and display the broadcast program information for each channel extracted from the satellite broadcast signal as a guide screen The method for determining whether the input key signal is the same kind of key signal when the key signal for scrolling the displayed guide screen is continuously input while the program guide screen for each channel is displayed. Stage 1; A second step of extracting program information for each channel in a time zone corresponding to the input key signal and scrolling the guide screen when the determination result is not the same type of key signal; A third step of determining a channel corresponding to a cursor position in the displayed guide screen if the same type of key signal is determined; Extracting program information corresponding to a time zone corresponding to the scroll key signal of the determined channel, and scrolling and displaying only program information of a channel where the cursor is located among a plurality of channels included in the guide screen; A fifth step of repeatedly performing the fourth step as many times as the input number of the input scroll key signal; When the processing of the input scroll key signal is finished, the program information for each of the remaining channels included in the guide screen is read, and the guide screen is scrolled and displayed with program information of a time zone corresponding to the scroll key signal. A method of scrolling a guide screen of a satellite broadcasting receiver including a sixth step is provided.

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 method of scrolling a guide screen of a satellite broadcast receiver according to an exemplary embodiment of the present invention. The key input unit 10, the controller 20, the user interface 30, The guide interface 40 includes a memory unit 50 and a graphic interface 60.

Referring to FIG. 1, the key input unit 10 is composed of key metrics on a remote controller or its own panel to generate a corresponding key signal by a user's operation, and provide the corresponding key signal to the controller 20. A control signal for generating a command corresponding to a key signal provided from the input unit 10 is generated. In particular, when a user manipulates the key input unit 10 and inputs a key signal for displaying program information for each channel. In addition, a control signal for displaying a program guide screen is provided to a user interface 30 to be described later. If the user interface 30 is provided with a control signal for displaying a program guide screen for each channel provided from the control unit 20, the user interface 30 may program a program for reading program information for each channel in the guide interface 40. An information request signal is generated.

Meanwhile, when the power of the initial satellite broadcasting receiver is turned on, the memory unit 50 stores program information for each channel provided from the transport demultiplexer, which is not shown, and the guide interface 50 provides a user interface. When the request signal for the program information for each channel is input from the 40, the program information stored in the memory unit 50 is read and provided to the user interface 30 again. In addition, the user interface 30 configures program information for each channel provided from the guide interface 40 as a guide screen of a predetermined type through a graphic interface 60 and displays it on the screen. That is, the graphic interface 60 configures program information for each channel provided from the user interface 30 as a program guide screen as shown in FIG. 2A and displays it on the screen.

On the other hand, each of the above-described interface unit, that is, the user interface 30, the guide interface 40, the graphic interface 60, a buffer box for temporarily storing various control signals input from the outside (mail box) Is present, which is used for communication between each interface. That is, when a message is transmitted from a certain processor (interface) to a specific processor, the message is transmitted to a mailbox of the corresponding processor, and the processor receiving the message sequentially reads and processes the message transmitted to its own mailbox.

Referring to Figure 1 in detail with respect to the method for scrolling the guide screen of the satellite broadcast receiver according to an embodiment of the present invention, the user is a key in the state that the program guide screen for each channel is displayed through each process as described above By operating the input unit 10, it is possible to refer to program information of another specific time zone that is not displayed on the current screen. In this general program guide screen, each time a key signal for scrolling the screen is input, the input signal signal corresponds to the input key signal. The time zone (eg, the left key signal is the previous time zone and the right key signal is the next time zone) is moved by a predetermined time unit (for example, 30 minutes or 1 hour unit).

Referring to FIG. 2A, as shown in FIG. 2A, the user operates the key input unit 10 to display the left scroll key signal while the program information for each channel from 9:00 to 11:00 is displayed. Upon input, the control unit 20 transmits the key signal provided from the key input unit 10 to a mailbox (not shown) in the user interface 30. The user interface 30 generates a request signal for reading the program information before a predetermined time (for example, 30 minutes) from the program information currently displayed on the screen based on the key signal transmitted to the internal mailbox. The mail is sent to the mailbox of the guide interface 40.

Subsequently, the guide interface 40 is displayed in the time zone corresponding to the key signal from the program information for each channel stored in the predetermined area of the memory unit 50 in response to the request signal transmitted from the user interface 30, that is, on the current screen. The program information of the time zone 30 minutes ago is read from the received program information and provided to the user interface 30 again. The user interface 30 transmits the program information transmitted from the guide interface 40 to the mailbox of the graphic interface 60, and the graphic interface 60 transmits the transmitted program information back to a predetermined program guide screen. By configuring and displaying, the program information of the time zone corresponding to the scroll signal input by the user is displayed on the screen.

Unlike in the above-described process, if a key signal for scrolling the guide screen is continuously input while the program guide screen for each channel as shown in FIG. 2A is displayed, for example, the program information of the next time zone is displayed. If the right key signal is repeatedly inputted continuously, the control unit 20 sequentially transmits the input right key signal to the mailbox of the user interface 30 as many times as the inputted key signal. At this time, the user interface 30 reads the key signal transmitted to its own mailbox, and as a result of the reading, the user interface when the key signal having the same contents, that is, the right scroll key signal as described above is repeatedly stored in succession. 30 determines the channel where the cursor displayed in the current guide screen is located.

The guide interface 40 provides a request signal for reading only program information of a next time zone for the channel where the cursor is currently located, and the guide interface 40 responds to the request signal of the user interface 30. From the program information for each channel stored in the channel 50, program information corresponding to the next time zone of the channel corresponding to the request signal, that is, the channel in which the cursor is located, is read and provided to the user interface 30 again, and the user interface 30 Provides the transmitted program information to the graphical interface 60. Accordingly, the graphic interface 60 updates and displays only program information of a specific channel (channel in which the cursor is located) provided from the user interface 30 among the plurality of channels in the guide screen displayed on the current screen. That is, as shown in FIG. 2B, only the program information of the channel where the cursor is located among the broadcast channels displayed in the current guide screen is read and scrolled.

In other words, when scroll key signals in the same direction are continuously input through the key input unit 10, the program information for the channel where the cursor is positioned is continuously scrolled first and then the same scroll key signal is repeatedly inputted. If a key signal for performing a specific operation or other specific operation is input, the program information for each remaining channel is moved and displayed as program information of a time zone corresponding to the input scroll key signal as shown in FIG. 2C.

As a result, when the scroll key signals having the same contents are continuously input while the program guide screen for each channel is displayed, the channel where the cursor is located is not scrolled and updated as many times as the number corresponding to the input key signal. After only scrolling and displaying only program information, and when the input of the scroll key signal is completed, the program information for each channel is updated and displayed, thereby improving the graphic processing speed according to the user's scroll key signal input.

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

On the basis of the program guide screen key signal input through the key input unit 10, the program guide screen for each channel having the form shown in FIG. 2A is displayed (step 301), and then again through the key input unit 10. When a key signal for scrolling the guidance screen displayed on the current screen to another specific time zone is input (step 303), the control unit 20 sequentially transmits the input key signal to the mailbox of the user interface 30 (step 305).

The user interface 30 reads the scroll key signal input to the internal mailbox (step 307) and requests the guide interface 40 for program information corresponding to the scroll signal, and the guide interface 40 In response to this, the program information for each channel of the time zone corresponding to the scroll key signal is read from the program information stored in the memory unit 50 (step 311), and is provided to the user interface 30 again. In this case, the user interface 30 provides program information for each channel transmitted from the guide interface 40 to the graphic interface 60, so that the user interface 30 responds to the scroll key signal input by the user for a predetermined time unit (for example, 30). The program guide screen scrolled by minute) is displayed (step 313).

Otherwise, in the step 303 described above, scroll key signals having the same content are continuously input repeatedly and sequentially transmitted to the user interface 30, and as a result of the reading in the step 307 described above, When the key signals are continuously input (step 309), the user interface 30 determines the position of the cursor included in the program guide screen displayed on the current screen (step 315). Then, a request signal for reading the program information of the channel corresponding to the determined cursor position is generated and provided to the guide interface 40, and the guide interface 40 responds to the entirety stored in the memory unit 50. Only the program information for the channel corresponding to the position of the current cursor is read from the program information for the channel, and is provided to the user interface 30 again (step 317). Subsequently, the user interface 30 transmits the program information of the specific channel (the channel where the cursor is located) provided from the user interface 40 to the graphic interface 60, and the graphic interface 60 is displayed on the current screen. In the program guide screen, only the program information of the channel where the cursor is located is scrolled and displayed (step 319).

Meanwhile, the user interface 30 reads each scroll key signal stored in the internal mailbox through the control unit 20 and repeats the process after the above-described step 317 to prioritize only the program information for the channel where the cursor is located. If the scrolling process for the same key signal ends (step 321), that is, there is no longer a key signal stored in the mailbox of the user interface 30 or another kind of key signal is displayed. In the case of input, a request signal for reading the program information for each of the remaining channels is generated in the guide interface 40.

Therefore, the guide interface 40 reads the memory unit 50 to read the program information for each of the remaining channels included in the program guide screen and provides the program information to the user interface 30 again (step 323). The user interface 30 By providing this to the graphical interface 60, the program information for all channels included in the guide screen is scrolled and displayed (325).

As a result, when the scroll key signals having the same contents are continuously input, the program information of the channel to be actually referred to by the user, i.e., without scrolling the entire program guide screen repeatedly as many times as the input key signal as in the conventional scroll method. Only the program information for the channel where the cursor is located is first read and scrolled, and when the input of the scroll key signal is interrupted, the program information for each channel is scrolled and displayed, thereby repeating internal processing, that is, the scroll being input. The process of deleting the guide screen and scrolling and displaying the guide screen as many times as the key signal can be omitted.

When the key signal for scrolling the screen is continuously input while the program guide screen for each channel provided by the satellite broadcasting receiver is displayed, the entire guide screen is not repeatedly scrolled by the number of key signals inputted. By scrolling the program information of the portion where the cursor is located first, there is an effect that a quick screen scroll function corresponding to the key signal input by the user can be performed.
