In addition, a dedicated content transfer program 111 for transferring content to the portable device is executed on the CPU 11 to transfer the selected content. In the content transfer program 111, the extraction unit 111a for extracting the folder name and file name of the storage destination of the content to be transferred, the tag information determination unit 111b for determining the presence / absence of tag information of the content, and the tag information could not be acquired. Sometimes, tag information generating means 111c for generating tag information based on the folder name and file name extracted by the extracting means 111a is included.

  The HDD 13 further stores various contents data such as audio data and video data, as well as various files. The keyboard 14 inputs an operation for instructing start and stop of music playback as an input means and switching information displayed on the display unit 7. The display 15 performs various displays for content transfer based on the operation of the keyboard 14. The network controller 16 is a controller that performs control for connecting to a network such as the Web via a wired or wireless connection. The USB terminal 17 executes communication with other connected devices.

  The power supply circuit 18 supplies operating power to each component using power from a battery 18a provided in the main body of the portable device 2 or power from an external AC adapter 18b.

Next, the system configuration of the portable device 2 will be described with reference to FIG.
As shown in FIG. 3, the portable device 2 includes a CPU 21, a memory 22, a hard disk drive (HDD) 23, a display (LCD) 24, operation buttons 25, a USB terminal 26, an audio controller 27, a headphone terminal 28, and a power supply circuit 29. A battery 29a, an AC adapter 29b, and the like.

  The CPU 21 is a processor that controls the operation of the portable device 2 and executes various programs (operating system, application program, etc.) loaded in the memory 22. The application program is a program for reproducing audio data and video data.

  The HDD 23 functions as a storage device for storing various content data such as audio data and video data. A display (LCD) 24 displays various operation menus, names of singers, album names, artist names, and the like of music reproduced by application programs. The operation button 25 inputs an operation for instructing start or stop of music reproduction or switching information displayed on the display unit 7. The USB terminal 26 executes communication with other connected devices. The audio controller 27 is a sound source device, generates a sound signal corresponding to the audio data reproduced by the application program, and outputs the sound signal to the headphone terminal 28.

  The power supply circuit 29 supplies operation power to each component using power from a battery 29a provided in the main body of the portable device 2 or power from an external AC adapter 29b.

  In such a configuration, in order to write content in the portable device 2, dedicated application software is installed in the personal computer 1, and music content stored in the hard disk in the personal computer 1 is transferred into the portable device 2. Among the contents, the audio format of the music contents uses data that is digitally compressed by a compression method such as MP3, WMA, or AAC that is currently popular in personal computers and the Internet.

  The connection between the portable device 2 and the personal computer 1 is realized by preparing connection connectors corresponding to the USB serial interface system and connecting these connectors with the cable 3. By connecting by the USB interface method, the personal computer 1 can automatically recognize that the portable device 2 is connected, and music contents can be automatically transferred according to the connection.

The operation when transferring contents such as music from the personal computer 1 to the portable device 2 will be described with reference to FIGS.
FIG. 4 is a diagram for explaining the concept of tag information generation at the time of content transfer, and FIG. 5 is a flowchart for explaining its operation.
In the personal computer 1, music content as digital data compressed in advance is stored in a hard disk (HDD) 13. The content stored in the HDD 13 is provided with ID tag information in addition to the song data itself, and the tag information includes an artist name, a song title name, an album name, and the like.

  However, some of the stored content 101 does not have tag information added for some reason, and some tag information cannot be read. When the content is transferred, the personal computer 1 checks the tag information of the content designated to be transferred. If the tag information cannot be acquired, the absolute path 102 of the content in which the content is stored is used. Tag information is generated 103 in accordance with a predetermined association rule, and content is transferred to the portable device. For this reason, the portable device 2 stores the content 104 with the tag information added.

A specific operation will be described below with reference to FIG.
When the transfer application software (transfer module) 111 is activated with the personal computer 1 and the portable device 2 connected, a list of contents currently stored in the HDD 13 is displayed on the LCD 15. Here, the user selects content to be transferred by using an input means such as the keyboard 14 (step S1). At this time, the content transfer instruction may be either a track unit or a folder unit. Accordingly, in the CPU 11, the extraction unit 111a of the content transfer program 111 extracts the folder name and file name of the designated content storage destination.

  Next, the tag information determination unit 111b of the content transfer program 111 reads the tag information of the selected content from the HDD 13 and acquires the tag information of the content.

  Next, in step S2, it is determined whether or not the tag information to be acquired has been acquired for the three pieces of information (artist name, album name, track name) necessary for tag management of music content on the portable device. (In addition to the above three pieces of information, genre information may be included).

Here, in step S2, if all the tag information can be acquired, the process proceeds to step S7 as it is.
Next, in step S2, when some tag information cannot be acquired, the acquired tag information is left as it is, and only missing information is generated, and the process proceeds to step S3. If there is no tag information, the process proceeds to step S3 in order to generate all the necessary three tag information.

  Further, if acquisition of tag information fails, it is determined that the tag is broken, the tag is initialized, and the process proceeds to step S3 in order to generate all necessary three tag information. Here, in the case of the type for exchanging commands, for example, MTP, the transfer to the portable device is transferred to the device together with the content as content description information.

  In step S3, the tag information generation unit 111c of the content transfer program 111 acquires an absolute path, which is a folder to be stored in the HDD 103 of the personal computer 1, for the content to be transferred (step S3) and sets it in advance. Tag information is generated based on the associated association rule S4 (the association rule will be described later) (step S5).

Then, the generated tag information is embedded in the content (step S6), and the content is transferred (step S7).
Here, depending on the content transfer program, when content is transferred from the information processing apparatus 1 to the portable device 2, the content to be played back on the portable device 2 is displayed, or related information is displayed on the screen during content playback. When transferring content, in addition to the content itself, related information (property information) generated based on information extracted from the tag information of the content information is transferred together There is also. In this case, information such as a song name, an album name, and an artist name generated by the above method using an absolute path can be reflected in related information (property information) and then transferred together with the content.

Next, an example of an association rule when tag information is generated from the acquired absolute path is shown.
The association between the absolute path and tag information is basically based on the folder name in order from the file name. If there is a delimiter (for example, a hyphen (-)) in the file name or folder name, Since the setting method differs depending on whether or not to divide, an association rule is set in advance.

For the setting of the association rule, an association rule setting menu is provided in the content transfer program, and the association rule is set in the setting menu.
FIG. 6 is a diagram illustrating an example of an association rule setting screen.
When the content transfer program is activated on the personal computer 1 and an association rule setting menu is selected, an association rule setting screen 200 is displayed.
Here, preset 1 (201), preset 2 (202), and preset 3 (303) are displayed as representative rule examples, and a user selection 504 is displayed so that the user can freely select a rule. Is done.

  Preset 1 (201) assigns the folder name to the tag information as it is, and assigns the folder name one level above the target file to the album name and the folder name two levels above to the artist. Therefore, if the absolute path is [c: \ music \ artist \ album \ track.mp3], the artist name is [artist], the album name is [album], and the track name is [track]. In general, since there are two or more levels of folder hierarchy, the folder name used as tag information is made to correspond from the folder on the file name side (that is, the lower folder). .

  Next, the preset 2 (202) is the same as the preset 1 in that the folder name is directly applied to the tag information, but the order of the tag information corresponding to the folder hierarchy is different. Specifically, the folder name one level above the target file is assigned to the artist name, and the folder name two levels above is assigned to the album name. Therefore, if the absolute path is [c: \ music \ album \ artist \ track.mp3], the album name is [album], the artist name is [artist], and the track name is [track].

  Preset 3 (203) is a method in which when a hyphen (-) is included in a file name, this is regarded as a delimiter and associated with tag information. Specifically, if the file name is [arthist-album-track.mp3] by assigning artist, album, and track in order of hyphens, the artist name is [artist], the album name is [album], The track name is [track].

  Finally, the user selection 204 allows the user to freely input association rules, and the order of association can be input using the sample shown in 505. Here,% 1 is a genre name,% 2 is an artist name,% 3 is an album name,% 4 is a track name (corresponding to a song name in the case of music data), and "\" and "-" can be freely combined Can be set. In the example of FIG. 5, the file name in the latter half of the file name corresponds to the track name, the album name between the two hyphens, and the first part of the file name corresponds to the artist name. In the example, the file name immediately before the file name is the genre name.

If there is no hierarchy assigned by the user setting, the tag information is set with the corresponding tag information blank.
Further, when the user has not set the association setting rule in advance, the tag information may be set with the preset 1 as the default rule.
As described above, in the present embodiment, the file name / folder name and the tag information setting rule can be freely set. Therefore, even if the content is saved according to the user's preference, the tag information is generated. Can be transferred to the portable device 2.
