Description:
CROSS-REFERENCE TO RELATED APPLICATION  
       [0001]     This application claims the benefit of Korean Application No. 2005-58044, filed Jun. 30, 2005, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     An aspect of the present invention relates to a composite image apparatus and a copy method thereof, and, more particularly, to a composite image apparatus and a copy method thereof wherein when files that are stored in a first storage medium are copied to a second storage medium, one or more folders are additionally created in the second storage medium so that one or more target files to be copied among the files stored in the first storage medium are separately stored in the additionally created folders and a copy folder of a folder of the first storage medium containing the target files.  
         [0004]     2. Description of the Related Art  
         [0005]     Generally, a composite image apparatus is an integrated system comprising two or more imaging devices. For example, a digital versatile disc (DVD) player (DVDP) and video cassette recorder (VCR) have been combined to form a DVDPNCR combo, and a hard disk drive (HDD) and a digital versatile disc drive have been combined to form an HDD/DVD recorder.  
         [0006]     Among these conventional composite image apparatuses, the HDD/DVD recorder comprises, as introduced in a web page of Toshiba Japan (www.toshiba.co.jp), an HDD and DVD drive installed in a cabinet. The HDD/DVD recorder stores externally supplied videos in the HDD or DVD (DVD-R/RW/RAM), and reproduces a video stored in the HDD or DVD. If necessary, selected videos stored in the HDD may be copied to the DVD or selected videos stored in the DVD may be copied to the HDD. This copy operation (generally referred to as “dubbing”) may be performed in various ways, such as a high speed mode and transrating mode.  
         [0007]     In addition to the videos, joint photographic experts group (JPG) files, moving picture experts group  1  (MPEG- 1 ), and audio layer  3  (MP 3 ) files may be stored on the DVD installed in the DVD drive of the HDD/DVD recorder and may also be stored in the HDD thereof. Selected JPG or MP 3  files stored in the HDD may be copied to the DVD, and selected JPG or MP 3  files stored on the DVD may be copied to the HDD.  
         [0008]     However, in this conventional HDD/DVD recorder, when a plurality of JPG files or a plurality of MP 3  files are copied, one or more target files to be copied among the files and a folder containing the target files are copied as they are. This may cause a problem in that some of the target files are not copied and are left out in the copy operation. This problem may occur when the target files stored on the DVD are copied to the HDD, because a copy folder created in the HDD has a limit in the number of accommodatable files. Consequently, if the number of the target files to be copied is larger than the number of accommodatable files in the copy folder created on the HDD, some of the target files excluding those accommodatable files in the copy folder of the HDD are not copied.  
         [0009]     In addition, if a large number of copied files are contained in the copy folder after the copy operation is performed using the conventional copy method, locating a desired file to be edited may not be easy and, thus, a long time may be required to edit the files contained in the copy folder.  
       SUMMARY OF THE INVENTION  
       [0010]     Therefore, an aspect of the invention provides a composite image apparatus and a copy method thereof wherein in a copy operation, in addition to a copy folder of a folder of a first storage medium containing one or more target files to be copied, one or more additional folders are created in a second storage medium to newly store the target files, and the target files are separately stored in the created copy folder and additional folders.

     DETAILED DESCRIPTION OF THE EMBODIMENTS  
       [0030]     Reference will now be made in detail to the present embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present invention by referring to the figures.  
         [0031]      FIG. 1  is a block diagram showing the configuration of an HDD/DVD recorder as a composite image apparatus according to an embodiment of the present invention. As shown in  FIG. 1 , the HDD/DVD recorder comprises a plurality of input terminals  19 ,  21  and  22 , a plurality of output terminals  25  and  26 , a plurality of analog-to-digital (A/D) converters  17 , a plurality of digital-to-analog (D/A) converters  18 , a digital video (DV) decoder  14 , a National Television System Committee/Phase Alternation Line (NTSC/PAL) decoder  15 , and an NTSC/PAL encoder  16 . The HDD/DVD recorder also comprises a switching circuit  27 , a moving picture experts group (MPEG) encoder  12 , an MPEG decoder  13 , a controller  30 , an on screen display (OSD) generator  29 , a buffer  11 , a DVD drive  10 , an HDD  20 , a display  23 , and a remote control receiver  24 .  
         [0032]     As for the input terminals,  FIG. 1  illustrates a digital interface terminal (DVin) denoted by reference numeral  19 , a video input terminal (Vin) denoted by reference numeral  21 , and an audio input terminal (Ain) denoted by reference numeral  22 . The DVin  19  receives audio video (AV) data of a DV format. The Vin  21  receives a video signal of an NTSC or PAL format transmitted from a tuner (not shown), a set-top box (not shown), or the like. The Ain  22  receives an audio signal transmitted from the tuner, the set-top box, or the like.  
         [0033]     As for the output terminals,  FIG. 1  illustrates a video output terminal (Vout) denoted by reference numeral  26 , and an audio output terminal (Aout) denoted by reference numeral  25 . The Vout  26  outputs a video signal of the NTSC or PAL format to a display device (not shown) connected to the Vout  26 . The Aout  25  transmits an audio signal to the display device.  
         [0034]     The DV decoder  14  converts the AV data of the DV format inputted via the DVin  23  into video and audio signals of an International Telecommunication Union-R (ITU-R) BT format. The NTSC/PAL decoder  15  converts the video signal of the NTSC or PAL format inputted via the DVin  21  into video and audio signals of the ITU-R BT format. The NTSC/PAL encoder  16  converts a video signal of the ITU-R BT format from the MPEG decoder  13  into a video signal of the NTSC or PAL format.  
         [0035]     The switching circuit  27  transmits the video signal from the NTSC/PAL decoder  15  to the MPEG encoder  12  and the OSD generator  29 . The switching circuit  27  transmits the audio signal inputted via the Ain  22  to the MPEG encoder  12  and the Aout  25 . To record the AV data of the DV format, the switching circuit  27  transmits the video signal from the DV decoder  14  to the MPEG encoder  12  and the OSD generator  29 , and transmits the audio signal from the DV decoder  14  to the MPEG encoder  12  and the Aout  25 . In a reproduction mode, the switching circuit  27  transmits the video signal from the MPEG decoder  13  to the OSD generator  29 , and transmits an audio signal from the MPEG decoder  13  to the Aout  25 .  
         [0036]     The MPEG encoder  12  compression-encodes the video signal of the ITU-R BT format and the digital audio signal in an MPEG- 2  format into an AV data stream. In contrast to the operation of the MPEG encoder  12 , the MPEG decoder  13  converts an AV data stream into a video signal of the ITU-R BT format and digital audio signal.  
         [0037]     The controller  30  controls a copy operation between the DVD and the HDD  20  and also controls all of the components of the HDD/DVD recorder. The controller  30  also generates an OSD image, which will be displayed by the display device connected to the HDD/DVD recorder, and provides the OSD image to the OSD generator  29 . Then, the OSD generator  29  displays the OSD image provided from the controller  30  on a screen of the display device. The buffer  11  is used to temporally store the AV data stream. The DVD drive  10  loads a DVD therein to read/write AV data from/to the DVD. The HDD  20  stores various data separately from the DVD drive  10 . Here, both JPG files, which are compressed still images such as typical photographs, and MP 3  files, which are compressed audio signals such as typical music, may be stored in the DVD or the HDD  20 . For example, the user may load a DVD in a DVD drive of a personal computer (PC) to download favorite photographs (JPG files) or songs (MP 3  files) to the DVD, then load the DVD in the DVD drive  10  of the HDD/DVD recorder and copy the photographs or songs stored on the DVD to the HDD  20 , thereby storing the JPG and MP 3  files in the DVD and HDD  20 .  
         [0038]     The remote control receiver  24  receives a signal from a remote controller  28  and transmits the received signal to the controller  30 . The remote controller  28  includes a menu button  31  to load or close a menu on the display device connected to the HDD/DVD recorder, an enter button  32  to select a desired item among items displayed on the screen of the display device, and up, down, left and right direction buttons  33   a ,  33   b ,  33   c  and  33   d  to provide an ability to virtually move a cursor among the items displayed thereon.  
         [0039]     Hereinafter, according to an embodiment of the present invention, a copy method of the composite image apparatus will be described with reference to  FIG. 2 . To copy desired JPG or MP 3  files stored in the HDD  20  to a DVD or to copy desired JPG or MP 3  files stored on the DVD to the HDD  20 , the user selects a copy item of the menu of the display device or presses a copy button provided on the remote controller  28 . Then, the controller  30  displays a screen as shown in  FIG. 3A  on the display device connected to the HDD/DVD recorder. The screen of  FIG. 3A  is used to guide the user to select a copy direction of either from the HDD  20  to the DVD or from the DVD to the HDD  20 . At this time, the user selects a HDD →DVD item to copy the files stored in the HDD  20  to the DVD or a DVD →HDD item to copy the files stored on the DVD to the HDD  20 .  
         [0040]     After the user selects the copy direction from  FIG. 3A  using the up, down, left and right direction buttons  33   a ,  33   b ,  33   c  and  33   d  and the enter button  32 , the controller  30  displays a screen similar to that which is shown in  FIG. 3B  on the display device. The screen of  FIG. 3B  is used to guide the user to select a desired file type among a title, JPG, or MP 3  file for target files to be copied which are stored in the HDD  20  or DVD. At this time, the user selects a Title item of  FIG. 3B  to copy titles, a JPG item to copy JPG files, or an MP 3  item to copy MP 3  files, through the up, down, left and right direction buttons  33   a ,  33   b ,  33   c  and  33   d  and the enter button  32 .  
         [0041]     If the user designates MP 3  files as the target files by selecting the MP 3  item from the items of  FIG. 3B , the controller  30  displays a list of all MP 3  type files stored in the HDD  20  or DVD on the display device, as shown in  FIG. 3C , so that the user may select desired target MP 3  files from the MP 3  file list displayed on the screen of the display device (operation  40 ).  
         [0042]     After the copy direction and target files to be copied are selected by the user as described above, the controller  30  displays a screen as shown in  FIG. 4A  on the display device to guide the user in determining whether one or more additional folders must be created.  
         [0043]     Namely, the user is requested to determine whether the additional folders must be created during a copy operation, as shown in  FIG. 4A . If the user chooses “Yes,” the controller  30  determines that the user desires to create additional folders in addition to a copy folder (operation  42 ), and displays a guide screen as shown in  FIG. 4B  on the display device to request the user to input the number of the additional folders to be created (operation  44 ). Here, the copy folder is a copied folder of a folder containing the target files, and is created in a storage medium in which the target files will be newly stored.  
         [0044]     If the user inputs the number of the additional folders to be created through number buttons of the remote controller according to the screen of  FIG. 4B  (operation  44 ), the controller  30  creates the copy folder and the additional folders where the number of the additional folders is the same as that inputted by the user, and separately stores the target files in the created copy folder and additional folders (operation  46 ).  
         [0045]     For example, to copy two hundred and fifty (250) music files (250 MP 3  files) contained in a folder A of the DVD to the HDD, if the user inputs nine (9) as the number of the additional folders to be created, nine folders are created in the HDD  20  in addition to a folder A&#39; acting as a copy folder of the folder A. Then, the two hundred and fifty music files contained in the folder A are separately stored in the folder A&#39; and nine additional folders, whereby each of the folders contains twenty-five music files.  
         [0046]     On the other hand, if the user chooses “No” at operation  42 , the controller  30  determines whether the number of the target files is larger than the number of files accommodatable in the copy folder (operation  48 ). If the number of the target files is larger than the number of files accommodatable in the copy folder, the controller  30  automatically creates one or more additional folders in addition to the copy folder and separately stores the target files in the created copy folder and additional folders (operation  52 ). For example, when the user tries to copy two hundred and fifty (250) music files (250 MP 3  files) contained in a folder A of the DVD to the HDD  20  without specifying any additional folder and if the number of files accommodatable in a folder A&#39; acting as a copy folder of the folder A is two hundred ( 200 ), the controller  30  creates an additional folder B in the HDD  200  in addition to the copy folder A&#39;, and stores two hundred target files in the folder A&#39; and stores the remaining fifty in the additional folder B, respectively.  
         [0047]     If the number of the target files is less than or equal to the number of files accommodatable in the copy folder at operation  48 , the controller  30  stores all of the target files in the copy folder without creating the additional folders in the medium in which the target files will be newly stored.  
         [0048]     The various guide screens of  FIGS. 3A  to  3 C and  FIGS. 4A and 4B  are illustrated for the purpose of description of the present invention, and thus may be illustrated in different manners from those of the figures.  
         [0049]     With reference to  FIG. 5 , another embodiment of a copy method of the composite image apparatus will be described below. As shown, many of the operations of the embodiment of  FIG. 5  are similar to the embodiment of  FIG. 2 , and, as such, a detailed explanation of those operations will be omitted.  
         [0050]     According to this embodiment, if the user decides to create additional folders and has inputted the specified number of additional folders to be created, the controller  30  determines whether the number of target files is larger than the number of accommodatable files in the copy folder and the additional folders, even where the files are apportioned equally among the copy folder and the additional folders (operation  480 ). If the controller  30  determines that the number of target files is less than the number of accommodatable files in the copy folder and the specified number of additional folders, the controller  30  creates the copy folder and the specified number of additional folders, and separately stores target files in the copy and additional folders (operation  490 ).  
         [0051]     However, if the controller  30  determines that the number of target files is larger than the number of accommodatable files in the copy folder and the specified number of additional folders, the controller  30  automatically creates a sufficient number of secondary additional folders, and separately stores the target files in the copy, additional, and secondary additional folders (operation  520 ).  
         [0052]     As is apparent from the above description, an aspect of the present invention provides a composite image apparatus and a copy method thereof, wherein in a copy operation where JPG or MP 3  files stored in an HDD are copied to a DVD or JPG or MP 3  files stored on the DVD are copied to the HDD, if the number of target JPG or MP 3  files to be copied exceeds the number of files accommodatable in a copy folder, one or more additional folders are automatically created to store some of the target files which cannot be accommodated in the copy folder. Consequently, none of the target files is left out in the copy operation.  
         [0053]     In addition, in the composite image apparatus and the copy method thereof according to an aspect of the present invention, if the user specifies the number of additional folders to be created during a copy operation, the target files are separately stored in the copy folder and the additional folders, where the number of the additional folders is the same as that specified by the user. Thus, the number of files in each folder decreases, facilitating editing work.  
         [0054]     Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
