Hereinafter, an embodiment in which a file stored in a disc inserted into the disc player 155 is continuously played using the video recording / reproducing apparatus having the above-described configuration will be described with reference to GUI screen processing.

4 is a screen showing a list of files stored in an inserted disc (not shown) on a display device, and FIG. 5 is a flowchart showing a control procedure for continuously playing a file of the present invention.

The disc player 155 is a device for playing a file stored in a DVD or a CD. These data files usually use extensions as arguments that indicate what type and type of file the file is. That is, the extension is determined according to the format of the character string, and the extension, which is mostly composed of three letters, is the basis for determining what information is used to view and edit the file. Therefore, even the same audio file can be recorded as a plurality of files having different extensions such as 'mp3', 'wma', 'wav', and other characteristics such as a movie file, a still image file, a text file, as well as an audio file. The files with can be recorded with different extensions. That is, as shown in Table 1 below, the video file, the still image file, and the audio file may have different extensions.

division Type of extension Video file WVV, VBS, MPV, DAT, VOB, MPG, etc. Still image file JPG, JPE, etc. Audio file WAV, MP3, MMP, AC3, DTS, DMC, ABX, MPA, WMA, ASF, etc.

The video files, still image files, and audio files having the extensions as shown in [Table 1] are divided into displayable files and are usually stored in the flash memory 165 to be modified, changed, and stored.

The main controller 160 reads information about the files recorded on the disc inserted into the disc player 155 (step 510) and checks the extension among the related information for each file to determine whether display is possible (step 510). 520). This is to determine whether each file extension is compatible with each other as shown in [Table 1]. If it is determined in step 520 that the file cannot be displayed, the main controller 160 processes the file not to be displayed on the display apparatus 300 (step 521).

In addition, the main controller 160 checks whether the files can be decoded in order to determine whether the respective files are played (step 530). In order to check whether the main controller 160 is a file that can be decoded with respect to a file stored in the HDD 151, a stream type must be checked. Every file must have an extension, but not a stream type. The stream type means that stream type information includes only 2 bytes of data that can be streamed, that is, decoded, among files. Therefore, by checking the stream type, it is possible to determine whether or not decoding is possible, that is, whether to reproduce.

The stream type is a data type of files recorded on the HDD 151. For example, the file recorded on the HDD 151 may be any type of various data types such as moving image data, still image data, audio data, text data, and animation data. To determine whether or not

The stream type is included in the ID3 tag for recording additional information (for example, music name, singer, production year, genre, etc.) for 'mp3' in the case of a file having an 'mp3' extension. As a result, when a file having a 'mp3' extension is recorded on the HDD 151, the main controller 160 checks the stream type included in the ID3 tag and determines whether it is decodable. Examples of the file that can be decoded include a video file, a still image file, an audio file, and the like as shown in [Table 2].

In Table 2, the icons on the left are designated to be displayed in different icon shapes through the GUI screen (FIG. 4), and are stored in the flash memory 165. As an example, the stream type "ICO0N_MP3" has an icon of ICON_MP3, which is represented by an icon of " MP3 " as shown in FIG.

That is, when a user requests a file list display request using the F-LIST 210 key of the remote controller 200, the main controller 160 decodes files that are decodable among the files recorded on the disk, that is, playback is performed. Possible files are those icons which are predetermined for each stream type as shown in [Table 2] in the flash memory 165 and the corresponding icons and files are displayed as shown in FIG. 4 (step 531).

The GUI screen illustrated in FIG. 4 is a file list screen 400, and is largely divided into an upper region (up), a middle region (mid), and a lower region (lower). In a predetermined block of the upper area up, a 'File List' is displayed indicating that this screen is a file list screen. In addition, a block indicating the name of the currently displayed folder and the total number of selected folders may be displayed at a predetermined position in the substantial area up. In the middle region, the file names and icons of the decodable files recorded on the disk are displayed. In the lower region, the key operation usage information of the remote controller 200 corresponding to the use of the file list screen 400 is displayed. Is displayed.

Decodeable files displayed in the middle of FIG. 4 are displayed in association with an icon and displayed in the order stored in the disk. In other words, the files are displayed in the order in which they are stored, regardless of the file type.

Preferably, the file selection bar 410 is located at the topmost file or directory of the file list displayed in the middle area mid to allow the user to easily select a desired file through the remote controller 200 or the key input unit 173. You can do that.

On the other hand, the main controller 160 may be displayed as an icon on the GUI screen as shown in FIG. 4 when displaying not only the files recorded in the disk player 155 but also the files recorded in the HDD 151 on the screen.

If it is determined in step 530 that the file cannot be decoded, the main controller 160 displays the icon on the display device 300 as an icon such as " ICON_UNKNOWN " in the icon display portion of the file (step 532). As described above, non-reproducible files indicated by an icon such as "ICON_UNKNOWN" are preferably displayed only by preventing the user from selecting them by key operation.

When the user selects a file to play by operating the file selection bar 410 in step 531, the main controller 160 determines whether the file selected by the user is a music file (step 532).

In the case of the music file in step 532, the main controller 160 reads the related music player program (step 533) and plays the music file (step 534). In detail, when the " MP3 I Don't want to" file is selected on the screen displayed as shown in FIG. 4, the main controller 160 performs an "mp3_action" related function to decode the "mp3" file from the flash memory 165. After the call is stored, the decoding value is stored in the SDRAM 167, the data is transmitted to the audio D / A converter 135, and the music file is reproduced and output to the external device. In operation 533, the main controller 160 may determine the type of the file by checking the stream type of the file stored in the disk.

On the other hand, if it is not a music file in step 532, the main controller 160 determines that the selected file is a video file, and reads the related video player program (step 535) to play it (step 536). That is, on the screen displayed as in FIG. ", The main controller 160 calls the" rom_slide_show "related function to decode the picture file from the flash memory 165, stores the decoding value in the SDRAM 167, and then transmits the data to the video encoder 137. Eventually, the image file is played and output to the external device.

In the above description, only the specific examples in which the file continuous playback method of the present invention is applied to a video recording / reproducing apparatus are described in detail, and it is apparent to those skilled in the art that various modifications and changes are possible within the technical scope of the present invention. Naturally, it belongs to the attached patent claim.

According to the file continuous playback apparatus of the video recording / reproducing apparatus and the display method thereof according to the present invention, all the programs recorded on the recording apparatus are displayed regardless of the type of the program, and the program selected by the user is selected regardless of the type of the file. This allows the user to watch the music file and the picture file in the selected order without distinguishing them.
