Description

Cursor position control method {CURSOR POSITION CONTROL METHOD}

The present invention relates to a caption broadcasting receiver, and more particularly, to a method of controlling a cursor position.

Currently, KBPS information is transmitted for an EPG (Electronic Program Guide) function that shows programs of various broadcasting stations according to time zones.

KBPS information is composed of the broadcasting station name and the broadcasting date, broadcasting order / date, program recognition name, broadcasting time and title of the programs scheduled to be broadcast in the broadcasting station.

The KBPS information is periodically transmitted in the same data stream so that the receiver can recognize and receive the beginning and the end of the information at any time after power-on.

Accordingly, it is possible to display the entire broadcast program guide screen showing the programs of various broadcasting stations at the same time by receiving the KBPS information.

In the current EPG guide, a program is simultaneously displayed for each broadcasting station in a 2-hour band.

However, the conventional technology has the inconvenience of having to find a broadcast program that you want to watch on the broadcast program guide screen.

Therefore, in order to improve the conventional problem, when a moving key is input in a broadcast program guide screen displaying programs of several stations for each time zone, a broadcast program is displayed by displaying a cursor at an arbitrary broadcast program position corresponding to the position of the previous cursor. An object of the present invention is to provide a method for controlling a cursor position, which can be used to inform a viewer whether or not the user is moving to.

In order to achieve the above object, the present invention provides a method for displaying a broadcast program guide of a predetermined time zone, wherein when moving the cursor to the left or the bottom in any broadcast program located at the boundary of the guide display, the time zone is shifted. When the cursor is displayed on the entire broadcast program and the cursor is moved upward or downward in an arbitrary broadcast program, the cursor is moved to a program that most overlaps with the previous program when there are a plurality of programs that can be moved.

That is, the present invention provides a method for displaying a program guide for a predetermined time period, the method comprising: displaying a moving key in a direction in which the remaining part is located on a program for which the entire period is not displayed; Pressing the left or right navigation key displays the program guide for the time zone in which the entire program is displayed, placing the cursor on the program, and pressing the up or down navigation key at any program location broadcasts that most overlaps with the current broadcast program. And positioning the cursor in the program.

If the cursor is moved upward or downward, if there is no broadcast information in the time zone of the currently displayed program guide, but there is broadcast information in another time zone, displaying a movement key in the direction of broadcast information while placing the cursor in the entire channel. It is characterized by including.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a block diagram of a closed caption broadcasting receiver according to an embodiment of the present invention. As shown therein, a tuner 110 that receives a broadcast signal and tunes and detects a channel desired by a user, and A video signal processor 120 for outputting an analog video signal through the intermediate frequency processing such as a composite video signal (CVBS) and a data slicer for separating a KBPS signal by inputting the composite video signal (CVBS) from the tuner 110. And a frame buffer 220 for storing the KBPS signal separated by the data slicer 210, and a cursor on an arbitrary program in response to the display and movement keys of the broadcast program for all channels in the broadcast program guide mode. Graphic controller 230 for reading and converting the KBPS signal stored in the frame buffer 220 into a graphic format for positioning, and data input and output and broadcast guidance of the frame buffer 220 The graphic controller 230 may be configured to determine a channel currently being broadcast, display broadcast programs of all channels upon request, and then position the cursor on a program currently being broadcast and to position the cursor at a specific program corresponding to the previous position when the cursor is moved. The microprocessor 250 for controlling, the image mixer 130 for mixing the output signal of the image signal processing unit 120 and the output signal of the graphic controller 230 to output to the image display device 140, and the user key While controlling the tuning frequency of the tuner 110 according to an input, the microprocessor 250 transmits it to the microprocessor 250 whenever a channel is changed and inputs a user key for a broadcast guide display request through the interface unit 240. 250 is configured as a TV microcomputer 150 to transmit.

Referring to the operation and effect of the embodiment of the present invention configured as described above are as follows.

When the user selects a specific channel after turning on the power, the TV microcomputer 150 controls the tuner 110 to tune to the specific channel.

Accordingly, when the tuner 110 detects a broadcast signal of a specific channel and outputs a composite video signal (CVBS), the video signal processor 120 performs intermediate frequency processing to restore the original analog video signal, and then restores the analog video signal. The signal is transmitted to the image display device 140 through the image mixer 130 so that an image is displayed on the screen of the image display device 140.

In this case, the TV microcomputer 150 transmits the information on the current viewing channel to the microprocessor 250 through the interface unit 240.

Accordingly, the microprocessor 250 stores the information about the current viewing channel transmitted from the TV microcomputer 150 in the frame buffer 220, and the TV microcomputer 150 stores the information about the current channel whenever the channel is changed. The data is transmitted to the microprocessor 250.

In addition, the data slicer 210 extracts the KBPS signal from the image signal CVBS from the tuner 110 and inputs it to the microprocessor 250.

At this time, the microprocessor 250 decodes the KBPS signal, generates broadcast program guide data for each time zone, and stores the data in the frame buffer 220.

Thereafter, the TV microcomputer 150 continuously checks whether there is a user key input for displaying a broadcast program guide while watching a broadcast program.

In this case, when the user key for displaying the broadcast program guide is input, the TV microcomputer 150 transmits a command to display the broadcast program guide to the microprocessor 250 through the interface unit 240.

Therefore, the microprocessor 250 decodes the broadcast information (KBPS) in the data slicer 210 to read the broadcast program currently being viewed, and then broadcasts the broadcast station for a predetermined time period (for example, 2 hours) based on the broadcast program. The graphic controller 230 is controlled to display the program guide and to position the cursor on the broadcast program being watched.

Accordingly, the graphic controller 230 reads the broadcast program guide data from the frame buffer 220, converts the program guide data into a graphic form to be actually displayed on the screen, and processes the cursor to be displayed at the broadcast program position currently being viewed. It is output to the image display device 140 through.

Thereafter, the viewer may move the cursor to an arbitrary broadcast program position by inputting up, down, left, and right keys provided on the remote controller. The process will be described below.

First, when KBPS information for each broadcasting station is sorted and stored in the frame buffer 220 as illustrated in FIG. 2, the movement of the cursor by the left and right moving keys will be described with reference to FIG. 3.

Assuming that the initial screen of the program guide is the same as that of Fig. 3a, the programs C, F, and N currently span two hours before 7:00 and after 9:00, exceeding the display range of two hours, so that there are continuous programs in different time zones. Is indicated by the left and right arrows.

At this time, when the left moving key is pressed while the cursor is located in the program C as shown in FIG. 3A, the microprocessor 250 displays a broadcast program guide for 6 to 7 hours as shown in FIG. 3B and continues the cursor in the program C. The graphics processor 230 is controlled to locate and indicate that the program C is a continuous program.

On the contrary, if the right shift key is pressed while the cursor is located in the program F as shown in Fig. 3C, the microprocessor 250 displays the broadcast program guide for 8 to 9 hours as shown in Fig. 3D and continues the cursor in the program F. The graphic processor 230 is controlled to be positioned.

As described above, in order to move the cursor to the program continuously even after moving the time zone of the broadcast program guide, remember the recognition name of the program indicated by the cursor before moving the time zone, move the cursor, and then select a program having the same recognition name. And locate the cursor.

In addition, when the broadcast program guide is stored in the frame buffer 220 as shown in FIG. 2, the process of moving the cursor using the up and down moving keys will be described with reference to FIGS. 4 and 5.

When the lower moving key is pressed in the broadcast program guide screen as shown in FIG. 4A, the microprocessor 250 controls the graphic controller 230 to move to the channel MBC by skipping the channel KBS2 on which the KBPS information is not received. The programs that can be moved downward in E) are 'M' and 'N'.

At this time, since the program M most overlaps with the program E, the microprocessor 250 controls the graphic controller 230 to position the cursor in the program M. FIG.

In order to position the cursor in the program M, the microprocessor 250 uses broadcast time information in the KBPS information extracted by the data slicer 210.

That is, the microprocessor 250 compares the broadcast time information of the program before the cursor movement with the broadcast time information of the programs to which the cursor is moved in the broadcast program guide screen of the two-hour broadcast program that is currently being viewed. The graphic controller 230 is controlled to move the cursor to a program having broadcast time information.

Afterwards, when the lower movement key is pressed again on the screen as shown in FIG. 4B, the microprocessor 250 skips the channel SBS for which KBPS information is not received and moves to the program Q of the channel EBS as shown in FIG. Will be placed.

Afterwards, pressing the down arrow again on the screen as shown in Fig. 4C displays the screen state as shown in Fig. 4A, where the cursor is located in the program E. This means that the program E is more in the program Q than the program F. Because it overlaps a lot.

If the upward movement key is continuously pressed while the cursor is located in the program F as shown in FIG. 5A, the microprocessor 250 skips a channel for which KBPS information is not received and skips the program that most overlaps with the previous program in 2 hours. By controlling the graphic controller 230 to position the cursor, the screens of FIGS. 5B to 5D are sequentially displayed.

Here, the reason why the screen is displayed as shown in FIG. 4B when the upward movement key is kept pressed is because the program E overlaps the program M more than the program F.

On the other hand, when KBPS information is received but there are no programs in the currently displayed time zone, that is, when the program guide data is stored in the frame buffer 220 as shown in FIG. 6, the lower or upper navigation keys are continuously pressed, FIGS. 7 and 8. You will see a screen like this.

First, if the lower navigation key is pressed, KBPS information is received, but the channel without a broadcast program in the current time zone (KBS2) displays the cursor in the entire time zone, and the channel without receiving the KBPS information (SBS) is skipped, and the most pre-move program is skipped. By placing the cursor in a program that overlaps a lot, the screen shown in Figs. 7A to 7D is continuously displayed.

On the contrary, if the upper navigation key is pressed continuously, the channel (KBS2) where KBPS information is received but the broadcast program is not present in the current time zone is displayed as in the case where the downward navigation key is pressed continuously, and the channel where the KBPS information is not received (SBS) By continuing to display the screen as shown in Figs. 8A to 8D, the cursor is placed on the program that most overlaps with the program before the move.

As described in detail above, the present invention has an effect of easily selecting a program by notifying a user of which program to move to by moving the cursor corresponding to a program currently being viewed when the cursor is moved on a broadcast program guide screen.

That is, the present invention provides the effect that the cursor has moved across the border after the movement when the left and right moving keys are manipulated in the case of the program across the boundary where the program guide is displayed.

In addition, the present invention provides an effect of facilitating program selection by easily knowing a channel receiving broadcast information by placing a cursor on a channel that receives broadcast information but is not displayed in the current time zone when operating the up / down navigation keys.
