Can be. Such image recording / reproducing apparatuses are being developed to support the use of various image sources such as satellite broadcasting signals, cable broadcasting, and network broadcasting through the Internet.

HDD is used as an AV (Audio & Video) data recording device because of the random access (Random Access) that directly access the desired data by using the address, the high data transfer speed and large capacity recording.

DVDP is a player that can play not only DVD (Digital Video Disk) but also data recorded on general compact disc (CD). A DVD can record four times more data than a normal CD, and provides high-definition and high-quality video and / or sound data using MPEG-based compression technology.

Such CDs and / or DVDs (hereinafter referred to as " disc ") can record various files including moving picture files, still picture files and audio files. For example, one CD contains the movie file "*. mpg ", still image files" * .jpg ", audio files" * .wav "," * .mp3 "," * .wma "and text files" * .txt ". Recordable.

Meanwhile, a conventional video recording / reproducing apparatus in which a DVDP and an HDD are merged has an auto play function for automatically reproducing a file recorded on a disc. The auto play function, that is, the auto play function, is, for example, when a music CD is inserted into the DVDP, the DVDP plays the music file recorded on the CD by itself without any operation. Typical audio files that can be played automatically include files recorded in '* .wav' format.

However, in the conventional video recording / reproducing apparatus, when a disc on which a plurality of files having different extensions are recorded is inserted, there is a case where the auto play function may not be executed even if a file capable of auto playback is recorded on the disc. That is, the conventional video recording / reproducing apparatus executes auto play only when at least one file having one type of extension capable of auto playing is recorded on one disc, and a plurality of files having two or more types of extensions are recorded. In this case, auto play cannot be executed or some files are ignored and auto play is executed. In addition, a list of music files is not displayed on a display screen such as a television. Therefore, inconvenience to perform a separate operation in order to play the music desired by the user occurs.

Hereinafter, when a file capable of autoplay is recorded on a disc such as a DVD or a CD inserted into the disc loading unit 155, the autoplay method according to the preferred embodiment of the present invention is described in more detail with respect to GUI screen processing. Explain.

4 is a flowchart illustrating a control procedure for an automatic reproducing method according to the image recording / reproducing apparatus of FIG. 2, and FIGS. 5 to 7 are displayed on a display apparatus when a disc is inserted into the disc loading unit of FIG. 2. FIG. 1 is a diagram illustrating an embodiment of a file list screen and an autoplay list screen. FIG.

First, a plurality of files having various extensions can be recorded on a disc such as a DVD or a CD. For example, a single disc may record a plurality of files having different extensions such as 'mp3', 'wma', 'wav', even if they are the same audio file. In addition, not only an audio file but also a file having other characteristics such as a moving picture file, a still image file, and a text file may be recorded on a single disc.

On the other hand, when a disc such as a CD is inserted into the disc loading unit 155, the main controller 160 checks the stream type for each of all files recorded on the disc by the loading of the disc loading unit 155. (S410, S420). This is because whether the entire file recorded on the disc can be decoded can be determined according to the stream type.

The stream type is a data type of files recorded on the disc. For example, the stream type can determine whether the file recorded on the disc is any of various data types such as movie data, still image data, audio data, text data, and animation data. do.

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 an 'mp3' extension is recorded on the disk, the main controller 160 checks the stream type included in the ID3 tag and determines whether it is decodable. As a file which can be decoded, a video file, a still image file, an audio file, etc. are mentioned, for example.

[Table 1] below is a table listing the types of extensions for each of the decodeable files such as a video file, a still picture file, and an audio file.

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.

For example, in [Table 1], video files are recorded in '* .mpg' format, still image files such as photos in '* .jpg' format, and sound data such as music is recorded in '* .wav' format. .

If it is determined by the stream type identified in step S420 that a file capable of decoding among the plurality of files recorded on the disk exists (S430), the main controller 160 determines whether at least two extension types of the decodable files are present. Check (S440).

If it is confirmed in step S440 that at least two extension types, the main controller 160 determines whether there is a file that can be automatically played (S450). A representative example of a file that can be automatically played is an audio file recorded with a 'wav' extension.

That is, if a '* .wav' file exists among the files that can be decoded in step S450, the main controller 160 automatically plays the '* .wav' file, and the file name of the decodable file is shown in FIG. Provided as a screen (S460).

The GUI screen shown in FIG. 5 is a file list screen 500, 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' indicating the file list screen 500 is displayed. In the middle area mid, a file name and an icon of a decodable file recorded on the disc are displayed. lower), the key operation usage information of the remote controller 200 corresponding to the use of the file list screen 500 is displayed.

Decodeable files displayed in the middle of FIG. 5 have various extensions (eg, at least two of 'wav', 'mp3', 'jpg', and 'mpg'), among which are automatically played. Since the file having the 'wav' extension exists, the main controller 160 controls the digital audio signal output terminal 117 to automatically reproduce the file having the 'wav' extension.

Then, during the execution of step S460, if the automatic playback stop signal is received by the operation of the remote controller 200, the main controller 160 is' *. The playback of the wav 'music file is stopped and only the file list screen 500 as shown in FIG. 5 is displayed on the television 300.

On the other hand, if the extension type of the files that can be decoded in step S440 is one kind, the main control unit 160 to automatically play the file recorded on the disk, and provides the file name of the file to be automatically played to the GUI screen as shown in FIG. (S460).

The GUI screen shown in FIG. 6 is an autoplay list screen 600, and a file extension capable of decoding and autoplay inserted into a disc (eg, 'wav', 'mp3', 'jpg', In the case of one of " mpg ", the file name of the file is displayed on the middle of the auto play list screen 600.

The auto play list screen 600 of FIG. 6 is a case where only files having a 'wav' extension capable of auto play are recorded on the disc inserted in the disc loading unit 155. That is, in operation S440, the main controller 160 may control the file to be automatically played even when the extension type is recorded as one type such as 'jpg' as well as 'wav'.

In addition, if it is determined in step S430 that there are no decodable files among the plurality of files recorded on the disk, the main controller 160 does not execute auto play and provides a GUI screen as shown in FIG. 7 (S490).

The GUI screen shown in FIG. 7 is a file list screen 700, and since no files capable of moving on the disk are recorded on the disk, no file list is displayed in the middle of the file list screen 700. It can be seen.

In the automatic playback method of the image recording / reproducing apparatus 200 as described above, if it is determined in step S450 that there is a file having another extension besides the file having the 'wav' extension, the main controller 160 may have a different extension type. It is also possible to auto-play files according to their priority by giving them priority. For example, when various files having extensions of 'wav' and 'mp3' are recorded on the disc, the main controller 160 automatically plays a file having the 'wav' extension first and then has the 'mp3' extension. The file can be played automatically.

While the above has been shown and described with respect to preferred embodiments of the present invention, the present invention is not limited to the specific embodiments described above, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.

According to the video recording / reproducing apparatus and the automatic reproducing method according to the present invention, after the memory device in which a plurality of files having two or more types of extensions are recorded is initially loaded, the files capable of automatic reproducing are recorded in the memory device. If it is determined, it is possible to execute the auto play function. In this way, the user can use the auto play function more simply by automatically playing after initial loading without performing a separate operation to play a file such as music recorded in the storage device.
