In the drawing, reference numeral 211 denotes a menu key used for instructing loading and closing of the menu guide list screen, and portions indicated by 213, 215, 217, and 219 are classified on the menu guide list screen for the listed menu. Left, right, up and down arrow keys used to indicate cursor movement. Reference numeral 221 denotes an enter key used to select a menu, and 223 denotes a return key used to return to the previous screen from the current screen. And, 225 is a storage key (REC) used to save the video.

The remaining keys are known general keys for manipulating the video and sound recording / reproducing apparatus 100, the television 300, and the like, and the detailed description thereof will be omitted.

Hereinafter, a method of selecting a first file to be stored in a memory and displaying on a screen and executing it, and subsequently selecting a second file to be stored in a memory and displaying on a screen and executing the second file will be described with reference to the accompanying drawings.

4A shows that the files selected from the data memory in the CPU 161 are first-in first-out, so that the first files 410 are stored in the FIFO memory 400, FIG. 2 files 420 are saved. The FIFO memory 400 having such a function may be provided in the main controller 160. As shown, the first files 410 selected in the data memory in the CPU 161 are stored in the FIFO memory 400 and the further selected second files 420 are stored in the data memory of the FIFO memory 400. It is stored in the remaining area in order. When the storage area of the FIFO memory 400 is completely filled, the FIFO memory 400 is sequentially exited from the stored file first. Specifically, if the first files A, D, G, and H 410 are selected, they are stored in the FIFO memory 400 and then the second files a, e, and f 420 are selected. These are also stored in the FIFO memory 400. However, because of the first-in, first-out, the files A, D, G, and H 410 first entered into the FIFO memory 400 from the FIFO memory 400 preceding the files a, e, and f 420. Will come out.

5A, 5B, 5C, and 5D show that the first files are selected and displayed, followed by the second files are selected and displayed further. This shows how file storage in the FIFO memory of FIG. 4 is implemented on screen.

First, when at least one first file in the first folder is selected, a selection mark 310 appears on the left side of the selected file. Of course, the selection mark 310 may be displayed in a place other than the left side of the file. Here, it can be seen that files A, D, G, and H are selected as the first files (FIG. 5A). When this is executed, a playlist screen is displayed and the first files are executed in sequence or randomly according to the user's adjustment (Fig. 5B). Subsequently, when selecting at least one second file stored in another location, that is, a second folder, or another medium, a selection mark appears to the left of the selected file (see Fig. 5C). As noted above, this indication may be displayed elsewhere than the left side of the file. Here, it can be seen that the files a, e, and f are selected as the second files (Fig. 5C). When this is executed, the play list screen is displayed again, and the second file is additionally displayed in the first file, and the first file and the second file are executed in order or randomly according to the user's adjustment (Fig. 5D).

Reference numeral 320 denotes an icon for performing a designated function, and 330 denotes an instruction for assisting a user's key manipulation. The other drawings are configured on a guide screen to help the user understand the description thereof.
