Description

  The present invention relates to a content playback apparatus that plays back content at a specified time.

  Content playback devices that play back content such as still images, moving images, character information, or music have become widespread. In the content playback device, not only playing back videos and still images, but also playing back multiple still images as a slide show, or extracting multiple still images from a video along the time axis and displaying them as thumbnails There are also things.

  The content playback device starts with content (content data) stored in a storage device such as a built-in or detachable HDD, USB memory, SD-CARD, CF-CARD, The content stored in the portable recording medium such as PCMCIA-CARD, DVD, or BD is reproduced.

  Some content playback apparatuses are equipped with a schedule function (software) for playing back content stored in a storage device at a specified time. According to this, the content can be automatically reproduced at the designated time by designating the start time in association with the content to be reproduced. Also, by designating the playback interval, it is possible to repeatedly play back at the specified interval.

  Patent Document 1 describes a technique for automatically reproducing contents in a memory in a specified order. According to this, the name of a file to be reproduced and its execution start time are stored in the order of reproduction to create a time table. Then, the audio file and the image file stored in the memory are reproduced according to the time table.

Japanese Patent Laid-Open No. 11-29883 (published on October 29, 1999)

  However, the schedule function (software) provided in the conventional content reproduction apparatus cannot automatically reproduce the content in the portable recording medium at a specified time.

  Therefore, in order to reproduce the content in the portable recording medium at a certain time, when the time comes, the user goes to the content reproduction device every time and sets the portable recording medium, You need to specify the folder or file that contains the content you want to play.

  However, each time the user wants to reproduce the content, visiting the content device and designating the folder or file of the content to be reproduced requires a complicated operation for the user.

  Further, the schedule function can be used by downloading the content in the portable recording medium to the storage device of the content reproduction device. However, downloading and specifying the start time and playback interval one by one is nothing but a troublesome task for the user.

  In addition, playing the content using the schedule function itself requires time-consuming settings, and it is easier to automatically play the content including the content stored in the storage device of the content playing device at the specified time. There is a need to develop technologies that can do this.

  In addition, in order to automatically reproduce at a specified time using the technique described in Patent Document 1, the specified time is an execution start time corresponding to an elapsed time since the execution start is instructed. It is necessary to instruct the execution start. Therefore, it is not practical as a method for automatically reproducing content at a specified time.

  Furthermore, in the technique described in Patent Document 1, content to be played back from an application is set. Therefore, when there is a lot of content, the set content and the content that has not been set can be easily obtained. I can't confirm. For this reason, there is a possibility that settings are forgotten for necessary contents.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a content reproduction apparatus that can easily reproduce a content stored in a portable recording medium or a storage device of a content reproduction apparatus at a desired time without requiring complicated work.

(Functional configuration)
FIG. 1 shows a block diagram of a functional configuration of content reproduction apparatus 100 according to the present embodiment. As shown in FIG. 1, the content playback apparatus 100 includes an input unit 101, an HDD (which may be built-in or detachable) 131, an HDD drive 130, a slide show execution unit (content playback unit) 103, and a playback target detection unit with time. (Reproduction target detection unit with time) 110, slide show information management unit 104, time control unit 106, and reproduction instruction unit (reproduction instruction unit) 107.

  The input unit 101 inputs content stored in the portable recording medium 10 into the content reproduction apparatus 100. Examples of the portable recording medium 10 include a USB memory, SD-CARD, CF-CARD, PCMCIA-CARD, DVD, and BD.

  The HDD 131 is a built-in or removable storage device in the content reproduction apparatus 100, and the HDD drive 130 reads various data including content stored in the HDD 131.

  The reproduction target detection unit with time 110 detects the content with time information by referring to the name attached to the content. The content is stored in the portable recording medium 10 and the HDD 131, and the name of the content file read by the input unit 101 or the HDD drive 130 or the name of the folder in which the content file is stored is referred to. A file with time information and a folder with time information including time information in the file name or folder name are detected.

  In the present embodiment, the playback target detection unit with time 110 includes a root folder information acquisition unit 102 and a time information detection unit 105.

  The root folder information acquisition unit 102 acquires information on folders and files stored immediately below the root folder of the portable recording medium 10 and the HDD 131. As the folder and file information, the names of folders and files in the root folder and the names of files in the folder are acquired. The file includes an image file and a sound file. In the present specification, unless otherwise specified, an image file and a sound file are used.

  The root folder is a folder on the uppermost layer of the portable recording medium 10 and the HDD 131. Depending on the type of the portable recording medium 10, it may be referred to as a root directory.

  FIG. 3 shows a storage example of the root folder “\\” of a certain portable recording medium 10. In the example of FIG. 3, three folders with names “1710”, “2030”, and “ABC” are stored directly under the root folder. Also, immediately below the root folder, five image files with names “image0001.jpg”, “image0002.jpg”, “image0003.jpg”, “image0004.jpg”, “image0005.jpg”, and Three sound files with names “music0001.mp3”, “music0002.mp3”, and “music0003.mp3” are stored.

  When such a portable recording medium 10 is inserted into the input unit 101, the root folder information acquisition unit 102 displays the folder names “1710”, “2030”, “ABC” image file names “image0001.jpg”, “image0002”. .jpg "," image0003.jpg "," image0004.jpg "," image0005.jpg ", sound file names" music0001.mp3 "," music0002.mp3 "," music0003.mp3 "are acquired.

  Further, in order to detect the playback order described later, the root folder information acquisition unit 102 also acquires the names of files stored in the folders “1710”, “2030”, and “ABC”.

  In the following, a process for automatically reproducing content with time information stored in a portable recording medium 10 shown in FIG. 3 at a specified time will be described. Similarly, the information acquisition unit 102 acquires the names of folders and files stored immediately below from the root folder of the HDD 131, and content with time information stored in the HDD 131 is also obtained. A process of automatic reproduction at the same designated time is performed.

  The time information detection unit 105 detects a folder with time information and a file with time information including the time information in the names of folders and files stored directly under the root folder. The time information detection unit 105 refers to the file name and folder name acquired by the root folder information acquisition unit 102 and detects a file with time information and a folder with time information including the time information in the name.

  In the present embodiment, the time information detection unit 105 extracts a four-digit number string “XXX” from the name, and the thousands and hundreds of digits are “00” and “00” representing 0:00 to 23:00. 01 ”,...“ 22 ”,“ 23 ”, and the tenth digit is an integer of“ 00 ”,“ 01 ”,...“ 58 ”,“ 59 ”representing 0 to 59 minutes. In this case, it is determined that it is time information.

  In this embodiment, the time information is a 4-digit number string. However, the time for reproducing the content may be specified up to a second unit as a 6-digit number string.

  Regardless of this function, when a four-digit number is included in a folder name or file name that happens to be added, it is assumed that the time information is detected and automatically reproduced. Therefore, in order to avoid such a situation, for example, a 4-digit number string followed by a character string such as “TIME” may be set to be detected as time information. In this case, when the time information detection unit 105 extracts a 4-digit number string from the name, the time information detection unit 105 extracts those with “TIME” after the name string, When the ten and one digit numbers are integers representing the hours and minutes described above, it is determined as time information.

  When the time information detection unit 105 detects the file with time information or the folder with time information, the time information detection unit 105 notifies the reproduction instruction unit 107 of the subsequent stage of the detection. Alternatively, the reproduction instruction unit 107 is notified of the name of the detected file with time information or folder with time information.

  In the example of storing the root folder shown in FIG. 3, the time information detection unit 105 determines that the two folders “1710” and “2030” are folders with time information including the time information in their names. Folder names “1710” and “2030” correspond to time information.

  When the file with time information or the folder with time information is detected, the reproduction instruction unit 107 sends the file with the time information or the file in the folder with time information to the slide show execution unit 103 at the time of the time information included in the name. To replay.

  The reproduction instruction unit 107 specifies the specified time from a 4-digit number string included in the file with time information or the folder with time information. For example, in the folder names including the time information of “1710” and “2030” described above, “17:10” and “20:30” are specified as the designated times.

  The playback instruction unit 107 is supplied with the current time as time information from the time control unit 106, and the current time and the file or folder directly under the root folder acquired by the root folder information acquisition unit 102. Are searched for a file or folder with time information including time information that matches the current time. Here, when the name of the file with time information or the folder with time information is notified from the time information detection unit 105, the current time and the file with time information or time information attached notified from the time information detection unit 105. What is necessary is just to collate the name of a folder.

  When the reproduction instruction unit 107 detects a file with time information or a folder with time information that matches the current time, the reproduction instruction unit 107 sets the file or folder as a reproduction file or a reproduction folder (reproduction target), and sends the file or folder to the slide show execution unit 103. Let it play.

  In the example of storing the root folder shown in FIG. 3, when the time information of the current time provided by the time control unit 106 is 17:10, the playback instruction unit 107 deletes the file in the folder “1710”. Let it play. Further, when the time information of the current time provided by the time control unit 106 is 20:30, the file in the folder “2030” is reproduced.

  In addition, the reproduction instruction unit 107 detects when the time information detection unit 105 does not detect the file with time information or the folder with time information, and even if it is detected, the file with the time information or the file in the folder with time information The file (without the time information included in the name) stored directly under the root folder is played back by the slide show execution unit 103 during the idle time until the time is played back at the time of the time information.

  The slide show information management unit 104 manages slide show information necessary for the slide show execution unit 103 to execute a slide show. The slide show information management unit 104 includes a file playback order detection unit (file playback order detection means) 115 and a slide show information storage unit 116.

  In the present embodiment, four pieces of playback time, playback order, playback cycle, and playback mode are used as slide show information. The slide show information storage unit 116 stores such slide show information.

  The reproduction time is information on the time for which the image file is continuously reproduced. Here, since a configuration is adopted in which still images are reproduced as a slide show, this corresponds to the time during which each still image is continuously displayed. Such a reproduction time is set in advance. In an image / sound synchronized playback mode, which will be described later, a sound file is played in synchronization with the playback of an image file. That is, even if the sound file is in the middle, when the playback time is reached, the sound file is finished playing and then switched to the sound file. On the other hand, in the image / sound reproduction mode, the sound file is reproduced regardless of the reproduction time of the image file, and the next sound file is reproduced when the reproduction of the sound file is completed.

  The reproduction cycle is information for setting whether the slide show is displayed only once (single) or repeated (repeat). In the single mode, the slide show is displayed only once for the files in the folder to be reproduced. In the repeat mode, the slide show display is repeated for the files in the folder to be reproduced.

  The playback order is information on the order in which image files and sound files are played back. The file playback order information is set for each folder by the file playback order detection unit (file playback order detection means) 115 based on the file name. The set information is stored in the slide show information storage unit 116.

  For example, in the example of storing the root folder shown in FIG. 3, the file structure directly under the root folder with the folder name “\\” is as shown in FIG. In the case of such a file configuration, the file playback order detection unit 115 sets the playback order of the image file from “image0001.jpg” → “image0002.jpg” based on the numbers “0001,0002,... ”→“ image0003.jpg ”→“ image0004.jpg ”→“ image0005.jpg ”, the playback order of the sound files is set to“ music0001.mp3 ”→“ music0002.mp3 ”→→“ music0003.mp3 ”.

  FIG. 4B shows a file structure directly under the “1710” folder. In the case of such a file configuration, the file playback order detection unit 115 determines that the playback order of the image file is “image1710_1.jpg” → “image1710_2” based on the numbers “_1, _2, _3,... .jpg ”→“ image1710_3.jpg ”, and the playback order of the sound file is set to“ music1710_1.mp3 ”→“ music1710_2.mp3 ”→“ music1710_3.mp3 ”.

  FIG. 4C shows the file structure immediately below the folder “2030”. In the case of such a file configuration, the file playback order detection unit 115 determines that the playback order of the image file is “image2030_1.jpg” → “image2030_2” based on the numbers “_1, _2, _3,... .jpg ”→“ image2030_3.jpg ”, and the playback order of the sound file is set to“ music2030_1.mp3 ”→“ music2030_2.mp3 ”→“ music2030_3.mp3 ”.

  The reproduction mode is information for setting the reproduction timing of the image file and the sound file. There are two types of playback modes: an image / sound synchronized playback mode and an image / sound playback mode.

  In the image / sound synchronized playback mode, the sound file associated with the image file is played back at the same timing as the image file. The association between the image file and the sound file is performed by including identification information that can identify each other in each name of the corresponding image file and sound file. The slide show execution unit 103 refers to the name of the image file to be reproduced, selects a corresponding sound file based on the identification information included in the name, and reproduces the sound file in synchronization with the image file. Since the playback of the sound file is synchronized with the playback time of the image file, the music file is switched along with the switching of the image file even if the playback of the sound file is not completed.

  For example, in the file configuration immediately below the root folder shown in FIG. 4A, when the image / sound synchronous playback mode is designated, the image file “ "image0001.jpg" and the sound file "music0001.mp3" are played back synchronously. here. “0001” is identification information. “0001” is also number information for determining the playback order.

  Subsequently, the image file “image0002.jpg” and the sound file “music0002.mp3” are reproduced in synchronization, and then “image0003.jpg” and the sound file “music0003.mp3” are reproduced in synchronization. After that, the image files “image0004.jpg” and “image0005.jpg” are played in order according to the playback order of the image files. The same identification information is included in these image files “image0004.jpg” and “image0005.jpg”. Since there is no sound file having, the sound file is not reproduced and only the image is displayed.

  Further, in the file configuration immediately below the folder “1710” shown in FIG. 4B, when the image / sound synchronized playback mode is designated, the playback order of the image files detected by the file playback order detection unit 115 is determined. The image file “image1710_1.jpg” and the sound file “music1710_1.mp3” are played back synchronously. here. “1710_1” or “_1” is identification information. “1710_1” or “_1” is also number information for determining the playback order.

  Subsequently, the image file “image1710_2.jpg” and the sound file “music1710_2.mp3” are played back synchronously, and then “image1710_3.jpg” and the sound file “music1710_3.mp3” are played back synchronously.

  On the other hand, in the image / sound reproduction mode, the reproduction timings of the image file and the sound file are managed separately and are reproduced at different timings. The playback time of the image file follows the preset playback time, but the playback time of the sound file follows the playback time of each sound file.

  For example, in the file structure directly under the root folder shown in FIG. 4A, when the image / sound reproduction mode is designated, the image file is in accordance with the reproduction order of the image file detected by the file reproduction order detection unit 115. Playback is performed in the order of “image0001.jpg” → “image0002.jpg” → “image0003.jpg” → “image0004.jpg” → “image0005.jpg” for the set playback time. On the other hand, the sound files are reproduced according to the order of the sound files detected by the file playback order detection unit 115 in the order of “music0001.mp3” → “music0002.mp3” →→ “music0003.mp3”. According to the time, it is played until the playback is completed.

  Further, in the file structure immediately below the folder “1710” shown in FIG. 4B, when the image / sound playback mode is designated, the image playback order is detected according to the playback order of the image files detected by the file playback order detection unit 115. The file is played in the order of “image1710_1.jpg” → “image1710_2.jpg” → “image1710_3.jpg” for each set playback time. On the other hand, the sound file follows the sound file playback order detected by the file playback order detection unit 115, in the order of “music1710_1.mp3” → “music1710_2.mp3” → “music1710_3.mp3”. Are played until the playback is completed.

  FIG. 5A, FIG. 5B, FIG. 6A, and FIG. 6B show examples of slide show information stored in the slide show information storage unit 116. FIG. In the example of FIG. 5A, “repeat” is set as the playback cycle, “image / sound playback mode” as the playback mode, and “30 seconds” as the playback time. In the example of FIG. 5B, “single” is set as the playback cycle, “image / sound synchronous playback mode” is set as the playback mode, and “35 seconds” is set as the playback time.

  FIGS. 6A and 6B show the file reproduction order in each folder determined by the file reproduction order detection unit 115 based on the file name. Among these, FIG. 6A shows the playback order of the image files in the root folder “\\”, the folder “1710”, and the folder “2030”. FIG. 6B shows the playback order of sound files in the root folder “\\”, folder “1710”, and folder “2030”.

  The slide show information management unit 104 can appropriately rewrite the playback mode, the playback time, and the playback cycle of the slide show information to be managed by using the instruction input device 12 connected to the content playback device 100. The instruction input device 12 may be an operation panel connected to the content reproduction device 100, an unconnected remote controller, or the like.

  When the playback instruction unit 107 instructs the playback instruction unit 107 to play a file in the root folder, a file in the folder with time information, or a file with time information, the slide show execution unit 103 plays the specified folder in the playback folder or playback. As a file, a slide show is displayed on the display device 11. When a playback folder is specified and a plurality of image files are stored in the folder, the slide show execution unit 103 can execute the slide show. However, when there is only one image file in the folder, or when reproduction of a file with time information is instructed, the slide show execution unit 103 continues to reproduce one still image. In the embodiment, such a single still image display is also included in the slide show.

  When the slide show execution unit 103 is instructed to play a folder and sets the designated folder as a playback folder, the slide show information management unit 104 reads slide show information necessary for executing the slide show such as the playback order of the playback folder. . Here, information of playback time, playback mode, playback cycle, and playback order is read. Then, the file data in the folder set as the playback folder is sequentially read from the portable recording medium 10 or the HDD 131 according to the playback order, and all files in the folder are played back according to the playback time, playback mode, and playback cycle. Do.

  On the other hand, when file playback is instructed and the instructed file is set as a playback file, the slide show execution unit 103 reads playback time, playback mode, and playback cycle information as slide show information. Then, the file data set as the reproduction file is read from the portable recording medium 10 and the HDD 131, and reproduction is performed according to the reproduction time, the reproduction mode, and the reproduction cycle.

  The slide show execution unit 103 includes an image / sound synchronous reproduction processing unit 111, an image / sound reproduction processing unit 112, and a loop processing unit 113.

  The image / sound synchronized playback processing unit 111 plays back an image file and a sound file when the image / sound synchronized playback mode is selected. On the other hand, the image / sound reproduction processing unit 112 reproduces an image file and a sound file when the image / sound reproduction mode is selected.

  The image / sound synchronous reproduction processing unit 111 sequentially reproduces the image file according to the reproduction order, and reproduces the sound file associated with the image file in synchronization with the reproduction timing of the image file. With reference to the name of the image file to be reproduced, the corresponding sound file is selected based on the identification information included in the name, and the sound file is reproduced in synchronization with the image file. The playback time of the image file is a preset playback time, and the playback time of the sound file follows this.

  The image / separate reproduction processing unit 112 sequentially reproduces the image file according to the reproduction order, and reproduces the sound file sequentially according to the reproduction order separately from the image file. The playback time of the image file is a preset playback time, but the playback time of the sound file is the playback time of each sound file.

  The loop processing unit 113 instructs the image / sound synchronous reproduction processing unit 111 and the image / sound reproduction processing unit 112 to reproduce the file for the slide show when the repeat mode is set as the reproduction cycle information. Repeatedly.

The display device 11 is a display device having a display function including a liquid crystal monitor and the like and an audio output function such as a speaker.

It is realized by doing.
(Operation of content playback device)
The content reproduction apparatus 100 according to the present embodiment includes a portable recording medium 10 inserted into the input unit 101, a folder with time information in which time information is included in the HDD 131 read by the HDD drive 130, or Detects whether or not a file with time information exists, and if it exists, the file stored in the folder or the file with time information including the time information in the name itself is included in the time information attached to the name. It is played back at the time. Here, as a content reproduction, a slide show display in which a plurality of still images are reproduced together with music information is illustrated.

  Below, a folder with time information or a folder with time information whose name includes time information is detected, and the file stored in the detected folder with time information or the file with time information is set to the time of the time information. An overview of the overall operation of the content playback apparatus 100 including the playback operation will be described. Here, the process of automatically reproducing the content with time information stored in the portable recording medium 10 will be described. However, the content with time information stored in the HDD 131 will be described. But the same is true.

  In the content playback apparatus 100, when the portable recording medium 10 is inserted into the input unit 101, the root folder information acquisition unit 102 of the timed playback target detection unit 110 passes through the input unit 101 in the portable recording medium 10. As root folder information, the names of folders and files stored in the root folder are acquired. In the case of a folder, the name of the file stored in the folder is also acquired.

  The time information detection unit 105 of the reproduction target detection unit with time 110 refers to the folder name and file name in the root folder acquired by the root folder information acquisition unit 102, and there is a folder or file that includes time information in the name. Detect whether or not When the presence of a time information-added folder or time information-added file whose name includes time designation information is detected, the reproduction instruction unit 107 is notified of the presence detection. Alternatively, the name of the detected file with time information or folder with time information is output to the reproduction instruction unit 107.

  The reproduction instruction unit 107 collates the time information supplied from the time control unit 106 with the names of files and folders in the root folder acquired by the root folder information acquisition unit 102. When the name of the file with time information or the folder with time information is notified from the time information detection unit 105, the name is checked with the name of the file with time information or the folder with time information.

  When the playback instruction unit 107 detects a file with time information or a folder with time information that matches the time information from the time control unit 106, the playback instruction unit 107 sets the file or folder as a playback target and Play the playback target.

  In addition, the reproduction instruction unit 107 notifies the slide show execution unit 103 of the root folder until the time specified by the time information is reached or when a folder with time information or a file with time information is not detected. Play the file stored in.

When a file or folder to be played is set by the playback instruction unit 107, the slide show execution unit 103 reads slide show information regarding the file or folder to be played from the slide show information management unit 104. Further, the files or files in the folder are sequentially read out from the portable recording medium 10 via the input unit 101, are reproduced based on the acquired slide show information, and the slide show is executed on the display device 11.
(Description of main operations)
FIG. 7A and FIG. 7B are flowcharts showing an outline of main operations of the content reproduction apparatus 100. Here, the process of automatically reproducing the content with time information stored in the portable recording medium 10 will be described. However, the content with time information stored in the HDD 131 will be described. But the same is true.

  In FIG. 7A, when the portable recording medium 10 is inserted and the start of slide show display is instructed, the content playback apparatus 100 starts and sets the root folder as a playback folder (step S1). Then, the playback order and playback time of the files in the root folder are read out (step S2, step 3).

  Next, it is determined whether or not there is a folder with time information or a file with time information whose name includes time designation information in the root folder (step S4). If there is a folder with time information or a file with time information, the process proceeds to step S5, and if not, the process proceeds to step S21 in FIG.

  First, the case where it progresses to step S5 is demonstrated. In step S5, the current time is acquired. Then, it is determined whether there is a folder or file whose name includes time information that matches the acquired time (step S6). Here, the object to be collated may be all folders and all files stored in the root folder, but the name of the file or folder determined to be the folder with time information or the file with time information in step S4. Extraction may be performed on the extracted object.

  If it is determined in step S6 that there is no match, the process proceeds to step S9, and it is determined whether all files in the reproduction folder have been reproduced. At the start, since the root folder is set as the reproduction folder, the process proceeds to step S12 until all the files in the root folder are reproduced, and the next file is reproduced. The details of the file reproduction process will be described later with reference to FIGS. 8A and 8B.

  When the next file is reproduced in step S12, the process returns to step S5, the current time is acquired, and it is determined whether there is a folder or file whose name includes time information that matches the acquired time (step S6). ).

  If it is determined in step S6 that there is no match, the process proceeds to step S9, and it is determined again whether all the files in the reproduction folder have been reproduced. Here, the process of moving from step S9 to step S12 is repeated several times, and the playback folder (the root folder is set as the playback folder at the start), that is, all files in the root folder are played back In step S10, the reproduction cycle is confirmed.

  If the single mode is set as the reproduction cycle in step S10, the process proceeds to step S13 to display the default image, and then returns to step S5.

  On the other hand, if the repeat mode (loop) is set as the playback cycle in step S10, the process proceeds to step S11, and the first file in the playback folder (the first file in the playback order) is set as the playback file. In step S12, the first file in the reproduction folder is reproduced. Thereafter, the process returns to step S5.

  When repeat mode (loop) is set as the playback cycle, file playback in the playback folder is repeated. That is, in step S6, the sequential reproduction (slide show) of all files in the root folder is repeated until it is determined that there is a folder with time information or a file with time information that matches the current time.

  On the other hand, in the state in which the default image is displayed or all the files in the root folder that is the playback folder are repeatedly played back, the time has passed and the time information of the folder with time information or the file with time information is changed. When the time is reached and it is determined in step S6 that there is a match, the process proceeds to step S7.

  In step S7, if there is a folder with time information that matches the current time, this is set as a playback folder. On the other hand, in the case of a file with time information that matches the current time, this is set as a reproduction file.

  When the playback folder is set, the process proceeds to step S8, and the playback order of the files in the folder with time information set in the playback folder is read. Determine whether all files have been played. In step S1, if the folder with time information has just been set as a playback folder, it is a matter of course that not all files have been played back, so the process proceeds to step S12 to play back the first file. Then, it returns to step S5 and enters step S6.

  In the file reproduction processing shown in FIGS. 8A and 8B described later, the process returns to step S5 many times until the reproduction time elapses. The current time acquired by the return coincides with the time when it is determined in step S6 that there is a folder or file that matches the time, but the reproduction instruction unit 107 already matches the current time. Since the folder with information is set as the playback folder, in step S6, it is determined that there is no matching folder, and the process proceeds to step S9.

  When step S9 and step S12 are repeated to reproduce all files in the folder with time information set in the reproduction folder, it is determined in step S9 that all files in the reproduction folder have been reproduced, and step S10 is performed. Go to and check the playback cycle. If the playback mode set for the folder is the single mode, the process proceeds to step S13 to display a default image, and then returns to step S5.

  On the other hand, if the repeat mode (loop) is set as the playback cycle in step S10, the process proceeds to step S11, and the playback file, that is, the first file in the folder with time information is set as the playback file. In step S12, the first file in the reproduction folder is reproduced. Thereafter, the process returns to step S5.

  When the repeat mode (loop) is set as the reproduction cycle, the time specified in the other time-information-added folder or time-information-added file is reached, and in step S7, these folders or files are reproduced folders or files. Unless it is set as, sequential playback (slide show) of all files in the folder with time information is repeated.

  On the other hand, in step S7, a file that matches the current time is a file with time information, and if this is set as a playback file, skip step S8 and proceed to step S9 to check whether the playback file has been played back. Judge whether. In step S7, if the file with time information has just been set as a playback file, naturally the playback file is not played back, so the process proceeds to step S12 to play back the playback file. Then, it returns to step S5 and enters step S6.

  Also in this case, in the file reproduction processing shown in FIGS. 8A and 8B described later, the process returns to step S5 many times until the reproduction time elapses. Although the current time acquired by returning to S5 coincides with the time when it is determined in step S6 that there is a folder or file that matches the time, the playback instruction unit 107 already matches the current time. Since the file with time information to be played is set as the reproduction file, it is determined in step S6 that there is no matching folder, and the process proceeds to step S9.

  In step S9, since the playback file has already been played back, it is determined that the playback file has been played back, and the process proceeds to step S10 to check the playback cycle. If the playback mode set in the file is the single mode, the process proceeds to step S13, the default image is displayed, and the process returns to step S5.

  On the other hand, if the repeat mode (loop) is set as the reproduction cycle in step S10, step S11 is skipped and the process proceeds to step S12 to reproduce the reproduction file. Thereafter, the process returns to step S5.

  When the repeat mode (loop) is set as the reproduction cycle, the time specified in the other time-information-added folder or time-information-added file is reached, and in step S7, these folders or files are reproduced folders or files. Unless this is set, the reproduction of the file with time information is repeated.

  On the other hand, if it is determined in step S4 that there is no folder with time information or a file with time information and the process proceeds to step S21 in FIG. 7B, it is determined whether all files in the reproduction folder have been reproduced. To do. If the root folder has just been set as the playback folder in step S1 of FIG. 7A, since all of the files have not been played, the process proceeds to step S24 and the files are played. Then, it returns to step S21 and repeats step S21 and step S24 until all the files in the root folder are reproduced. If the process from step S21 to step S24 is repeated several times and all the files in the playback folder, that is, the root folder are played back, the process proceeds to step S22 to check the playback cycle.

  In step S22, when the single mode is set as the reproduction cycle, the process proceeds to step S25, the default image is displayed, and the slide show reproduction ends.

  On the other hand, if the repeat mode (loop) is set as the playback cycle in step S22, the process proceeds to step S23 to set the playback folder, that is, the first file in the root folder as the playback file. Proceeding to S24, the first file in the reproduction folder is reproduced, and then the process returns to step S21. In this case, when the repeat mode (loop) is set as the reproduction cycle, the sequential reproduction (slide show) of all files in the root folder as the reproduction folder is repeated.

  Next, the file reproduction process that is the process of steps S12 and S24 will be described. FIG. 8A and FIG. 8B are flowcharts showing an outline of a file reproduction process which is a subroutine.

  As shown in FIG. 8A, in the file reproduction process, the reproduction mode is confirmed (step S31). In the reproduction by image / sound, the process proceeds to step S32. In the reproduction reproduction by image / sound, the step of FIG. Proceed to S42.

  First, the reproduction by image / sound will be described. In step S32, reproduction (display) of the image file set in the reproduction file is continued, and in step S33, reproduction of the sound file set in the reproduction file is continued.

  In a succeeding step S34, it is determined whether or not the reproduction time has elapsed. If not, the process proceeds to step S38. On the other hand, if it is determined in step S34 that the reproduction time has elapsed, the process proceeds to step S35 to reproduce the next image file. Then, the reproduction time counter is cleared (step S36), the reproduction time counting is started (step S37), and the process proceeds to step S38. If the next image file does not exist, such as the last image file in the reproduction order or an image file with time information, steps S35 to S37 are skipped.

  In step S38, it is determined whether or not the reproduction of the sound file has been completed. If the reproduction of the sound file has not been completed, the process returns to step S5 or step S21 of the main routine of FIG. On the other hand, if it is determined that the reproduction of the sound file is completed, the process proceeds to step S39 to reproduce the next sound file, and then returns to step S5 or step S21 of the main routine of FIG. If it is the last sound file in the playback order or a sound file with time information and there is no next sound file, step S39 is skipped.

  Here, in step S1 and step S7 of FIG. 7A, when this subroutine is entered for the first time after the playback folder is set or the playback file is set, step S32, step S33, step S34, step S38. Are skipped, the first image file is reproduced in step S35, and the first image file is reproduced in step S39.

  For example, when the root folder is set as a playback folder in step S1 of FIG. 7A and this subroutine is first entered in step S12 of FIG. 7A or step S24 of FIG. 7B. In step S35 and step S39, the first image file “image0001.jpg” and the first sound file “music0001.mp3” are reproduced.

  Next, when this subroutine is entered, it is determined in step S34 whether or not the playback time has elapsed since the start of playback of the first image file “image0001.jpg”. In step S35, the second image file “image0002.jpg” is reproduced.

  Similarly, when this subroutine is entered next, in step S38, it is determined whether or not the reproduction of the first sound file “music0001.mp3” has been completed. If it is determined that the reproduction has been completed, the process proceeds to step S39. The second sound file “music0002.mp3” is reproduced.

  On the other hand, in the case of image / sound synchronous playback, the playback (display) of the image file set in the playback file is continued in step S41, and the playback of the sound file set in the playback file is continued in step S42. To do.

  In subsequent step S43, it is determined whether or not the reproduction time has elapsed. If not, the process returns to step S5 of the main routine of FIG. 7A or step S21 of FIG. 7B. On the other hand, if it is determined in step S43 that the reproduction time has elapsed, the process proceeds to step S44, where reproduction of the next image file is started. Subsequently, a sound file having the same file number (identification information) is searched (step S45), and it is determined whether there is a sound file having the same file number (step S46). Here, if there is, reproduction of the sound file having the same file number is started (step S47), and the process proceeds to step S48. On the other hand, if there is no sound file having the same file number, the process without sound output is performed in step S50, and then the process proceeds to step S48. In step S48, the reproduction time counter is cleared, and then reproduction time counting is started (step S49). Thereafter, step S5 of the main routine of FIG. 7A or step S21 of FIG. 7B is performed. Return to. If the next image file does not exist because it is the last image file in the reproduction order or an image file with time information, step S44 to step S49 are skipped.

  Here, in step S1 and step S7 of FIG. 7A, when the playback folder is set or the subroutine is entered only after the playback file is set, step S41, step S42 and step S43 are skipped. In step S44, the first image file is reproduced. In steps S45 to S46, the sound file associated with the first image file is searched. If there is, the sound file is retrieved in step S47. Reproduce.

  For example, when the folder “1710” in FIG. 4B is set as the reproduction folder in step S7 in FIG. 7A and this subroutine is first entered in step S12 in FIG. 7, step S44 is executed. The first image file “image1710_1.jpg” in the folder “1710” is reproduced, and the sound file “music1710_1.mp3” associated with the first image file “image1710_1.jpg” is reproduced in steps S45 to S47. Is selected and played.

  Next, when this subroutine is entered, in step S43, it is determined whether or not the playback time has elapsed since the start of playback of the first image file “image1710_1.jpg”. Then, the process proceeds to step S44, and the second image file “image1710_2.jpg” is reproduced. In step S45 to step S47, the sound file “music1710_2.mp3” associated with the second image file “image1710_2.jpg” is selected and reproduced.

  Next, a content storage method by the user for using such a content playback apparatus will be described with reference to FIGS. Here, an example in which content with time information is stored in the portable recording medium 10 is given, but the same applies to the case where content with time information is stored in the HDD 131.
