  In the metadata input screen 43 of FIG. 5, a metadata display field 43a for displaying specific metadata regarding each condition input by the character input button 43c, and a metadata item to which the metadata to be input belongs are selected. Metadata item selection button 43b, a character input button 43c for inputting a character string of specific metadata relating to each condition displayed in the metadata display field 43a, and a setting for confirming the input metadata as one condition An example in which a button 43d is provided is shown. Here, as an example of the metadata item selection button 43b, one of the artist name, album name, and genre name is selected.

  In the metadata input screen 43 of FIG. 5, an artist name is selected as the metadata item selection button 43b, and “abcd” is input as metadata specifying the artist name by the character input button 43c. An example displayed in the metadata display field 43a is shown.

  In the metadata input screen 43 of FIG. 5, in order to enter a condition to be registered as one of playlist registration conditions in the metadata display field 43 a and the metadata item selection button 43 b, and to confirm the input condition, When the user performs the pressing operation of the setting button 43d from the input unit 3, the condition is fixed, and the screen display is switched to the metadata setting screen 42 in FIG. Metadata input as a condition is displayed on the screen in the corresponding condition column.

In the example of FIG. 4, in the column of Condition 1 indicated by reference numeral 42a, as specified metadata category 42a _1, "artist" is also, as a specific metadata 42a ₂ showing the artist name, "abcd" is After the screen is displayed and “condition 2” indicated by reference numeral 42b as the next condition is displayed on the screen, the setting button 42b ₃ in “condition 2” is pressed to set the next condition. Then, the screen is switched to the metadata input screen 43 in FIG. 5, and “genre” is indicated by the metadata item selection button 43 b in FIG. 5 as the metadata classification item 42 b ₁ related to the condition 2 and the designated genre name is displayed. specific metadata 42b _2, in a state where "Rock" is input by the character input button 43c in FIG. 5, pressing Misao the setting button 43d in FIG. 5 By shows a case where the screen of the display unit 4 is switched back to the meta-data setting screen 42 of FIG.

Note that the metadata setting screen 42 in FIG. 4 includes a storage medium selection button 42c for reselecting a storage medium storing the content to be registered in the playlist, and the content to be registered in the playlist. A condition save button 42d for registering the set conditions in the memory 2 as the target metadata 2b ₂ for content search when all the conditions necessary as the metadata for search are set is further provided. Yes. That is, when the user presses down the storage medium selection button 42c on the metadata setting screen 42 in FIG. 4, the storage medium selection screen shown in FIG. 3 is displayed on the screen, while the condition save button 42d when performing depressing operation, and registers in the memory 2 the conditions set in the metadata setting screen 42 as a target metadata 2b _2, the process proceeds to operation of creating a playlist.

Thereafter, returning to the flowchart of FIG. 2, the operation of registering the target metadata 2b ₂ that condition about the metadata of the content to perform registration in the playlist 2a is set, registered content to the playlist 2a, play The operation up to the reproduction operation of the content registered in the list 2a will be further described. In the metadata setting screen 42 of FIG. 4, as described above, a condition necessary for searching for content to be registered in the playlist 2a is set (step S8), and the pressing operation of the condition saving button 42d is performed. Is performed, the conditions set in the metadata setting screen 42 are registered in the memory 2 as the target metadata 2b ₂ (step S9). After that, the operation shifts to an operation for automatically creating a playlist.

First, find the target storage medium 2b ₁ of the play list registration condition 2b that is created in the memory 2, of the storage medium has been registered, a storage medium unexecuted content searching, priority is most A high storage medium is selected (step S10). Next, one piece of content metadata stored in the selected storage medium is acquired from the top (step S11).

Thereafter, the target metadata 2b ₂ of the playlist registration condition 2b created in the memory 2 is searched, and one or more registered target metadata are selected one by one in order of priority, and acquired from the storage medium. It collates with the metadata of the content that has been made (step S12). If the metadata of the content acquired from the storage medium does not match one or more registered target metadata (No in step S13), the content acquired from the storage medium is excluded from the playlist registration target. (Step S15).

  On the other hand, if the metadata of the content acquired from the storage medium matches all of the registered one or more target metadata (Yes in step S13), the metadata about the content and the path information about the content Is registered in the playlist 2a of the memory 2 as a playlist generation path (step S14). Here, the playlist generation path to be registered in the playlist 2a, that is, the path information related to the content is the location information indicating the storage medium in which the content is stored and the storage location in the storage medium.

A specific registration example is shown in FIG. FIG. 6 is a schematic diagram showing an example of a playlist in the present invention. The playlist 2a shown in FIG. 6, the subject of the content stored in the storage medium corresponding to the target storage medium 2b ₁ which is registered as a playlist registered condition 2b, is registered as a playlist registration condition 2b Information related to content having metadata matching the registered content of the metadata 2b ₂ is registered, and artist name 2a ₁ , album name 2a ₂ , genre name 2a ₃ , and play list generation that are metadata related to each content path 2a ₄ is at least registered.

In reproducing the content in accordance with the registered contents of the playlist 2a, in turn to play, retrieve the playlist generation paths 2a ₄ regarding content from the playlist 2a, based on the playlist generation paths 2a ₄ taken out, The content is reproduced by accessing the location information in the storage medium in which the content is stored, reading the content, and outputting the content to the content reproduction unit 5.

  Hereinafter, the description will be returned to the flowchart of FIG. When the process for determining whether or not the one content acquired from the selected storage medium is registered in the playlist 2a is completed, it is confirmed whether or not the next content is still stored in the selected storage medium (step S16). If the next content still exists (Yes in step S16), the metadata about the next content is acquired (step S17), the process returns to step S12, and the conditions to be registered in the playlist 2a are satisfied. If the content is satisfied, the process of registering in the playlist 2a is repeated.

On the other hand, it reaches the end of the recorded contents of selected storage medium, the said storage medium when the next content did not exist by searching the (No in step S16), and target storage medium 2b _1, content Not It is confirmed whether or not the search target storage medium 2b ₁ still exists (step S18). If the target storage medium 2b ₁ whose content has not been searched exists (Yes in step S18), the storage medium corresponding to the target storage medium having the next highest priority is selected (step S19), and the process returns to step S11. Then, the process of determining whether or not the content stored in the storage medium satisfies the condition to be registered in the playlist 2a is repeated.

On the other hand, when the search processing for all the contents stored in the storage medium corresponding to the target storage medium 2b ₁ is finished and there is no target storage medium 2b ₁ whose contents are not searched (No in step S18). ), The process of registering in the playlist 2a is terminated, and then the process proceeds to the operation of reproducing the content based on the registered playlist 2a. Here, when content is reproduced according to the registered content of the playlist 2a, the content is normally reproduced in order from the top of the playlist 2a.

  However, the flowchart shown in FIG. 2 shows an example in which the playback order of contents can be appropriately edited by the user. That is, when the registration process to the playlist 2a is completed, the registered content of the playlist 2a is first displayed on the screen of the display unit 4 (step S20). When the user confirms the registered content of the playlist 2a displayed on the screen and considers that the user wants to change the content, the input unit 3 switches the playback order or deletes the registration information regarding the content that does not require playback. Or edit the registered content of the playlist 2a (step S21). Thereafter, the contents are sequentially extracted in accordance with the registered contents of the playlist 2a, and are converted into analog information and amplified in the content reproduction unit 5 to be reproduced and output from the liquid crystal monitor, the speaker, or the like of the display unit 4.

As described in detail above, in the playlist 2a creation process of the present embodiment, among the storage media that are already connected to or accessible to the information playback device 10, the target storage registered in advance as the playlist registration condition 2b. With respect to one or a plurality of storage media corresponding to the medium 2b ₁ , all contents stored in the respective storage media are searched, and the target metadata 2b ₂ registered in advance as the playlist registration condition 2b is completely matched. By extracting content having metadata and registering it in the playlist 2a, the playlist 2a in which the content to be reproduced is registered is automatically created.

  According to the present embodiment, as described in detail above, the playlist 2a automatically created based on the metadata relating to the content stored in one or more storage media designated as the playlist registration condition 2b by the user. Can be used to sequentially play back the content that the user wants to view, so even if multiple storage media are used, it is possible to reselect the storage medium that stores the content that you want to view, as in the prior art. It can be omitted.

  Further, in the present embodiment, content stored in a storage medium that is not designated as the playlist registration condition 2b by the user is excluded from creation of the playlist 2a. This makes it possible to create the playlist 2a earlier and to quickly reproduce the content based on the playlist 2a.

The registered content of the playlist 2a in which the content to be viewed is registered may be automatically updated when a predetermined update condition is satisfied. Here, the update condition is, for example, when any of the following conditions occurs. When such a condition occurs, it is assumed that the content to be reproduced has changed, for example, the flowchart of FIG. The update process (the process after step S10) may be started to perform the entire update process of the playlist 2a.
(1) the play list registration condition 2b (target storage medium 2b _1, object metadata 2b ₂₎ When the registration contents of the changes.
(2) during playback of the content based on the play list 2a, when the content to be reproduced is not present (i.e., when the play list reproduction, to be located (playing in the storage medium indicated by the playlist generation paths 2a ₄ When the content file does not exist in the content path area).
(3) When the storage medium registered as the target storage medium 2b _{1 in} the playlist registration condition 2b is once removed and then reconnected (that is, the storage medium is connected by the plug and play function of the information reproducing apparatus 10). When reconnection is automatically detected).
