The present invention relates to an apparatus for controlling an image recording and reproducing apparatus using a tablet, and more particularly, to a GUI apparatus having a tablet function for recording, editing, and retrieving various control commands and multimedia data.                         

In general, an electronic device such as a television, a VTR, or a DVD has adopted a remote controller (remote controller) capable of controlling a remote function separately from a key input unit installed in a main body to perform all functional operations of each device.

The remote control for remote function control is not only due to the H / W and S / W technology improvement of the devices, but also due to the appearance of complex recording / playback-related functions and complex products. It is getting bigger. In addition, due to the development of electronic technology, devices are becoming smaller and smaller (Compact), and there is a problem that more functions need to be installed in a small size remote controller. Various electronic devices have solved the problem somewhat by leaving only some function buttons of the remote controller and integrating all functions available to the user using a specific function button so that they can be used in common. In order to create, add or edit data arbitrarily set by the user, another key is required separately, which is inconvenient because characters cannot be input using existing numeric keys and function keys.

Hereinafter, a data input method using a general remote controller will be described with reference to the drawings. 1 is a block diagram schematically illustrating a DVD / HDD combo system, and includes a switching unit 10, an MPEG encoder unit 20, a hard disk drive (HDD) 30, a flash ROM 40, And a control unit 50, a RAM 60, a light receiving unit 70, a digital signal processing unit 80, and an optical media player 90.

The switching unit 10 receives various image data / audio data sources from the outside or outputs the image data source output from the digital signal processing unit 80 to the outside (for example, a monitor screen). The MPEG encoder unit 20 is composed of a video decoder 21, an audio ADC 22 and the MPEG encoder 23, and after analog-to-digital conversion of the analog form of the image data source applied from the switching unit 10, It is compressed in MPEG format (eg MPEG-2 format). The hard disk drive (HDD) 30 is configured to store or read image data / audio data having an MPEG format in a data recording area in the form of a file.

The flash ROM 40 stores an operating system and an application program for operating a DVD player, and stores image data / audio data stored in the form of a file in a hard disk drive (HDD) 30. A program list GUI (Graphic User Interface) 200 showing additional information (icon, title name, recording time, file size, etc.) accordingly is stored. The program list GUI 200 is generally divided into an upper region 210, an interruption region 230, and a lower region 250, and the lower region 250 is a character for informing the use of key operation of the remote controller 72. "Instructions" is displayed.

The controller 50 stores the MPEG data output from the MPEG encoder unit 20 to a hard disk drive (HDD) 30 or digitally reads the image data / audio data stored in the hard disk drive (HDD) 30. Program list GUI of the image data stored in the form of a file in the hard disk drive (HDD) 30 by controlling the system to be applied to the signal processor 80 and executing an application program stored in the flash ROM 40 ( 200) is displayed on the screen so that the user can modify and edit.

The memory (RAM) 60 loads the control unit 50 when editing the file stored in the hard disk drive (HDD) 30.

The light receiving unit 70 is generated from a remote control device 72 for controlling the video recording / playback apparatus (for example, channel switching, volume control, image quality control, etc.) or a setting key (not shown) provided in the video recording / playback apparatus. The control signal (not shown) is received and applied to the controller 50.

The digital signal processing unit 80 receives the MPEG format image data stored in the hard disk drive (HDD) 30 via the control unit 50, decodes it, and converts the image data into a video format (for example, NTSC / PAL). The converted signal can be reproduced in an image display apparatus such as a television.

The DVD player 90 reads out image data and audio data from the DVD disk and applies the same to the controller 50. Image data and audio data applied to the controller 50 are stored in the hard disk drive (HDD) 30 or applied to the digital signal processor 80 and reproduced.

The remote controller 72 is composed of function keys and numeric keys 0 to 9 for performing a composite function.

Hereinafter, a process of controlling the device by using the daemon controller of the above configuration will be described. Since the general functions on the remote controller 72 operate in a specific mode as in the normal remote controller, detailed description thereof will be omitted. That is, as shown in FIG. 1, since the remote controller 72 is complicatedly composed of numeric keys and general function keys, it is difficult for a user to additionally arrange a key for modifying data. Therefore, although the character input GUI as shown in FIG. 5 is displayed for convenience, the character input is very difficult with the conventional remote controller, with reference to the program list GUI of FIG. 2 and the character input GUI of FIG.

When the user selects the program list menu to edit data, the controller 50 stores the image data file stored in the root directory area of the hard disk drive 30 as shown in the program list GUI of FIG. 2. At the same time as reading the guide information for the program, the program list GUI 200 stored in the flash ROM 40 is read out, and the data to be edited is listed and displayed in the interruption area 230 of the screen. In general, for convenience of the user, the image data file guide information is stored in the still image information 201, the title information 202, the storage date information 203, and the total length of the program extracted from a predetermined portion of the entire image data of each stored image data. Corresponding playback time information 204 is included.

In this case, a cursor may be positioned for each guide information in the guide information of the image data file listed on the screen, and the guide information is highlighted by the positioned cursor. Therefore, when the user places the cursor on the file before the file name modification, the file is highlighted. Normally, when the program list GUI 200 is displayed on the TV 100, the cursor is located in the first field that can be edited (in this example, indicated by "1"). In order to correct "Adventure", selection can be made only by operating the cursor up, down, left, and right several times.

In addition, in order to modify data while the program list GUI 200 is displayed, a command for selecting a character input key (not shown) of the remote controller 72 to display the virtual character input GUI 400 on the screen is provided. 50), the virtual character input GUI 400 is displayed on the TV 100. Similarly, in the virtual character input GUI 400, since the cursor is located at the initial character "·", a problem arises in that the user moves the left, right, up and down arrows for moving the cursor several times in order to input "Z".

The present invention is to solve the above problems, to provide a device that can easily control commands and data editing on the remote control by adding a tablet function to the remote control.

Graphical user interface device using a tablet according to the present invention for achieving the above object stores a control command GUI and a text input GUI and the area coordinates for the respective control commands and characters, and stores a pointer icon consisting of an arrow shape Display the pointer on a memory and a TV, display the GUI of the area coordinates according to the movement position of the pointer, and control the video recording / reproducing apparatus using the GUI of the area coordinate selected by the pointer or input the character data. It comprises a control unit for controlling.

The control command GUI is configured to display a plurality of commands that can control operations related to playback and recording of the video recording / reproducing apparatus, and when the command for editing data is selected while the control command GUI is displayed, It is preferable to control to display the character input GUI.

Further, when the pointer is to be displayed when the power of the video recording / reproducing apparatus is turned off, it is more preferable to first turn on the power of the video recording / reproducing apparatus and to display the pointer on the TV.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram schematically illustrating a DVD / HDD combo system according to an embodiment of the present invention, FIG. 4 is an example of a control command GUI display using a tablet, and FIG. 5 is a character using a tablet in an edit mode. Input GUI display diagram.

As shown in the drawings, the present invention replaces the functions of the control unit, the remote control device and the flash ROM in the prior art configuration, and since the general configuration is the same as the conventional configuration, the detailed description will be omitted and the functions of the flash ROM and the remote control differ from each other. Only the control unit will be described.

Flash Rom 140 is a memory for storing data, and stores an operating system and an application program for operating a DVD player, and image data / audio stored in a file format on a hard disk drive (HDD) 30. Program list GUI (Graphic User Interface) 200 showing data and additional information (icon, title name, recording time, file size, etc.) and virtual character input GUI displayed on the screen when editing the data ( 400). Also stored is a control command GUI 300 which displays a usable key menu including a play command GUI 310 and a record command GUI 320 usable in the playback mode and the recording mode. The playback command GUI 310 preferably configures all control commands available in the playback mode in the form of a GUI, and the recording command GUI 320 allows all the control commands that the user can operate in the recording mode to be displayed. In addition, an icon of the pointer 550 to be displayed on the screen in the tablet mode is stored, and the absolute position and control of the pointer 550 to be displayed in the program list GUI (Graphic User Interface) 200 and the virtual character input GUI 400 is shown. Each command (in this embodiment, a playback command GUI such as FPS, RPS, FF, REW, PLAY, STOP, STILL, OFF, and a recording command GUI such as REC, STOP, STILL, OFF) is performed in the command GUI 300. The area coordinates (location data) and the virtual character input GUI 400 also store the area coordinates where each character data is located. Preferably, the pointer is configured in an arrow shape so that the pointer can be easily identified on the screen. The control command GUI 300 also stores the relative position at which the playback command GUI 310 is to be displayed and the relative position at which the recording command GUI 320 is to be displayed. 310 may be displayed or the recording command GUI 320 may be displayed.

The remote controller 500 includes a tablet function switching key 510, a selection key 540, a tablet pen 530, and a tablet 520. When the tablet function switching key 510 is turned on, the pointer 550 is displayed at a predetermined position on the screen of the TV 100. When the user touches the tablet using a finger or the tablet pen 530, the displayed pointer 550 is displayed. Relevant data is transmitted to the light receiving unit 700 so that the user touches the tablet 520 using the finger or the tablet pen 530 in the direction to move the displayed pointer 550 while watching the TV 100. The pointer 550 of the TV 100 is operated to move in the up, down, left, and right directions according to the touch operation.The tablet function switching key 510, for example, performs an on / off switching operation when the switching button is pressed. The switch button is configured to be operated in such a way that it can be executed The selection key 540 is configured to operate as an enter key when the pointer 550 is moved to select a desired control command or key. It may be configured to be operated by the enter key when touched twice in succession 520. The remote controller using the tablet receives position data, ie, relative position information, to which the pointer 550 is moved on the tablet 520. 70. The conventional tablet remote control can use the technique described in Korean Patent Laid-Open Publication No. 1998-018618 (name of the remote control device), and the detailed description thereof will be omitted.

The controller 150 stores the MPEG data output from the MPEG encoder unit 20 to a hard disk drive (HDD) 30 or reads out image data and / or audio data stored in the hard disk drive (HDD) 30. The system is controlled to be applied to the digital signal processor 80 as much as possible. In addition, when the tablet function switching key 510 is turned on in the remote controller 500 through the light receiving unit 70, the control command GUI 300 and the pointer 550 icon are read from the flash ROM 140 and correspond to each command. The relative position (area coordinate) to be read is read. The read control command GUI 300 is displayed on the TV 100 and causes the pointer 550 to be displayed at a predetermined position (absolute position) of the TV 100. Thereafter, the TV 100 controls to change the relative position of the pointer 550 according to the position data transmitted from the remote controller 500. As shown in the figure, when the pointer 550 reaches the upper predetermined position of the TV 100, the playback command GUI 310 composed of the playback related commands is displayed on the upper side, and when the lower predetermined position is reached, the recording command GUI 320 composed of the recording related commands ) May be displayed, and the playback command GUI 310 may display each command independently so that the pointer 550 may be displayed when the pointer 550 reaches the corresponding area or boundary.

Of course, when the tablet function switching key 510 is turned on, the playback command GUI 310 and the recording command GUI 320 may be simultaneously displayed.

When the recording command GUI 320 is displayed, moving the pointer 550 on the remote control 500 to select “EDIT” causes the application stored in the flash ROM 40 to be executed to execute a hard disk drive (HDD) ( The program list GUI 200 of the image data stored in the form of a file in 30) is displayed on the screen and the virtual character input GUI 400 for character input is displayed, while the pointer 550 indicates the first character in the displayed alphanumeric. Display to turn on.

Hereinafter, a method of controlling the DVD / HDD combo system using a graphic user interface device using a tablet according to an embodiment of the present invention will be described.

When the tablet function switching key 510 is turned on in the remote controller 500 through the light receiving unit 70, the controller 150 reads out the control command GUI 300 from the flash ROM 140 and displays the TV 100 as shown in FIG. 4. The pointer 550 is displayed at a predetermined position (absolute position), and the control command GUI 300 is displayed on the screen. Of course, when the tablet function switching key 510 is turned on, only the pointer 550 is first displayed on the screen. Then, when the pointer 550 approaches the upper area (including the boundary) of the screen, the playback command GUI 310 is displayed. Alternatively, the recording command GUI 320 may be displayed in a lower predetermined area (including a boundary). Also, the playback command GUI 310 may display each command independently so that the pointer 550 corresponds to a corresponding area or boundary surface. You can also make them appear separately. For example, when the relative position of the pointer 550 is changed according to the position data transmitted from the remote controller 500 to approach the "FPS" area, only the command of "FPS" is displayed, and then the pointer 550 is moved in order. "RPS", "FF", etc. can be displayed. Of course, since the control command GUI 300 has a state position at the absolute position where the initial pointer 550 is displayed, the pointer 550 displayed on the TV 100 receives the relative position data transmitted from the remote controller 500. At the same time as modifying the relative position of the control command GUI (300) to move the pointer to each of the relative area or the boundary surface approaching the related control command GUI (300) can be displayed. On the other hand, when the power supply of the DVD / HDD combo system is turned off, the control command GUI 300 may be displayed on the screen while applying power at the same time. Thereafter, in the tablet 520 of the remote control 500, the user moves the pointer 550 displayed on the TV 100 using a finger or the tablet pen 530 to double touch or select a key ( When pressing 540, the controller 150 controls the system to perform a related operation. In other words, it is possible to perform a related command simply by moving the display pointer 550 to a predetermined area on the TV 100 without any key operation.

Hereinafter, a process of data modification while the recording command GUI 320 is displayed will be described. That is, when the user moves the pointer 550 to select the "EDIT" area, the controller 150 controls the program list GUI 200 and the virtual character input GUI 400 to edit data in the flash ROM 140. At the same time as reading and displaying on the TV 100, the pointer 550 is positioned at the first character of the virtual character input GUI 400 (" " in the present embodiment) and the position is set to an absolute position. Thereafter, in the remote controller 550, the user moves the pointer 550 displayed on the TV 100 by using a finger or the tablet pen 530 on the tablet 520 of the remote controller 500. By placing the 550 and pressing the selection key 540, the selected character is input.

As described above, the present invention allows a GUI to be related to the operation of the device on a screen by using a tablet, and assigns a relative position to each other so that all commands can be performed simply by moving the pointer. .

While the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the spirit of the invention, and such modifications and variations belong to the appended claims.

As described above, when the graphic user interface device using the tablet according to the present invention is used, not only key operation can be performed but also multimedia data can be easily recorded or edited.
