Detailed description of the function will be omitted.

Hereinafter, when a file that can be displayed as an icon is recorded on the HDD 151 using the video recording / reproducing apparatus having the above-described configuration, the method for displaying the icon according to the preferred embodiment of the present invention is related to GUI screen processing. It demonstrates in more detail.

4 is a diagram illustrating an icon display method displayed on a display device when a file is stored in the HDD 151, and FIG. 5 is a flowchart illustrating a control procedure for displaying an icon.

Typically, the HDD 151 can record a plurality of files having various extensions, such as a program recorded on a DVD or a CD. Every program and most data files have an extension, which is used as an argument to indicate what type and type of file the file is. The extension, which consists mostly of three letters, is for displaying only the information of the file, which is the basis for deciding which information to use 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 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. As shown 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 in '* .wav' format. 151, which is also displayed.

The main controller 160 reads information about the files recorded in the HDD 151 (step 510) and checks the extension among the related information for each file (step 520). This is to determine whether the file is displayable or not and whether the file extension is compatible with each other as shown in [Table 1]. This is to prevent the non-playable file, i.e., a file for which no playback program exists, from being displayed on the screen. If it is determined in step 520 that the file cannot be displayed, the file is processed not to be displayed on the display device (step 521).

In addition, the main controller 160 checks whether the files can be decoded in order to determine whether the respective files can be 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. Accordingly, the stream type "PURE_MP3" is controlled by the main controller 160 so that the corresponding icon is displayed as the icon " MP3 " as shown in FIG. 4, and the stream type is "PURE_MUSICAM" or "PES_MUSICAM" under the same control. If " MP2 " is displayed, the stream type "PURE_WMA" is icon-capable " WMA ", and if the stream type is "PURE_DTS" or "PURE_DTS_SWAPPED", it can be displayed as an icon such as " DTS ". In addition, as shown in Fig. 4, it can also be displayed as a camera icon.

The icon classification table for each stream type in [Table 2] may also be pre-stored and used in the flash memory 165. In addition, a specific icon may be mapped and automatically stored according to the icon classification table. You can also change, delete, or add icons in.

The main controller 160 displays the icon that can be decoded from among the files recorded in the HDD 151, that is, the files that can be played back, according to the predetermined icon for each stream type as shown in [Table 2]. And display as shown in FIG. 4 (step 531). That is, as shown in FIG. 4, the list of files recorded on the hard disk drive is provided as a GUI screen for each icon.

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' indicating that this screen is a file list screen is displayed, and a block indicating the name of the currently displayed folder and the total number of selected folders is allocated. In the middle region mid, the file names and icons of the decodable files recorded on the HDD 151 are displayed. In the lower region, the key operation of the remote controller 200 corresponding to the use of the file list screen 400 is displayed. Usage information is displayed.

The decodable files displayed in the middle region of FIG. 4 are represented by various icons by the classification table of [Table 2]. In other words, by displaying different icons according to the types of files, the user can easily identify the types of files.

In addition, when a file to be reproduced by the light receiver 171 is selected through the operation of the remote controller 200 during the screen display of FIG. 4, the main controller 160 controls the system to read and play the selected file from the HDD 151. It is.

Meanwhile, even when the main controller 160 displays not only the files recorded on the HDD 151 but also the files to be played through the disk player 155, the main controller 160 reads the files recorded on the disk and displays an icon on the GUI screen as shown in FIG. You can also mark

If it is determined in step 530 that the file cannot be decoded, the main controller 160 displays an icon such as " ICON_UNKNOWN " on the icon display portion of the file (step 532). As described above, files such as "ICON_UNKNOWN" are displayed so that the files that cannot be played are not displayed by the user but are only displayed.

In the above description, only the specific examples in which the icon display function of the present invention is applied to an image 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 patent claim.

According to the icon display image recording / reproducing apparatus and the method of displaying the same according to the present invention, the user is provided with a list of files by using an icon instead of displaying only the programs recorded in the storage device as files, thereby allowing the user to view the types of files currently stored. It is easy to recognize.
