Contains information about the start address of the program.

Figure 5 shows a flow chart according to a preferred embodiment of the menu screen display method having an image playback function according to the present invention.

First, in order to display the program list menu 210 for the image data stored in the hard disk drive (HDD) 30 on the screen, the program list 210 menu should be selected in the initial menu guide screen 200. To this end, when the menu key 101 provided in the remote control device 100 is pressed, a control signal (not shown) generated by the remote control device 100 is applied to the light receiving unit 70, and the control unit 50 detects this (S300). The initial menu guide screen as shown in FIG. 3 is displayed on the screen (S400).

Next, after positioning the cursor on the program list menu 210 using the direction keys (102 to 105) in the initial menu guide screen 200, pressing the enter key 106, the control signal generated from the remote control device 100 Is applied to the light receiving unit 70, the control unit 50 detects this (S500) and displays a menu as shown in Figure 4 on the screen (S600). At this time, in the menu displayed on the screen, icons 211a to 211d corresponding to the programs stored in the hard disk drive (HDD) 30 are displayed in the form of still images, and on the right side of each icon 211a to 211d, the program is displayed. Name, storage time, and playback time are displayed.

Next, as shown in FIG. 4, when the cursor is positioned on any one of the plurality of icons 211a to 211d by pressing the direction keys 102 to 105 in the program list menu 210 shown on the screen (S700). The icon located calls a program stored in the hard disk drive (HDD) 30 (S800). The still image of the icon reproduces the first start frame, that is, the I frame of the program stored in the hard disk drive (HDD) 30, and when the cursor is positioned on the icon (211a to 211d), the hard disk drive ( The program is loaded from the HDD 30 and played back (S900). At this time, the size of the video data reproduced on the screen in response to the call of the icon is the same as the size of the icon (any one of 211a to 211d). That is, the icons 211a to 211d displayed on the program list menu 210 are reproduced and displayed as moving pictures. On the other hand, when the icon where the cursor is positioned (for example, 211a) is played as a video, if the cursor is placed on another icon (for example, 211b), the video played corresponding to the icon 211a is stopped and the icon where the cursor is newly placed ( For example, the video corresponding to 211b is played on the screen.

At this time, the icon 211a which has stopped playing displays the still image of the first I frame of the program corresponding to the icon (for example, 211a) on the screen.

If you want to display the image data played back in the area where the icons 211a to 211d are located more quickly, press the direction keys 102 and 103 provided in the remote control device 100 to double the speed such as 2 times, 4 times and 1/2 times. You can implement this by setting it up.
