Description

  According to the present invention, in a device using data recorded in a memory, it is possible to detect that the data in the memory is updated by a personal computer or the like and to easily update the database indicating the information on the data in the memory. It is related with a data update management system.

  For example, in-vehicle audio devices receive radio and television broadcasts, play back general CDs and DVDs, and record many tunes recorded with mp3 etc. on data recording media such as CDs and large-capacity memories, and play them back. You can listen to it. In addition, a portable audio device having a large-capacity memory and a hard disk is brought into a vehicle, connected to a high-performance in-vehicle audio device, and music of the portable audio device is read and played.

  In such an in-vehicle audio apparatus, media that is software that can play back music data recorded in various compression formats such as mp3 and WMA in order to support music playback of various media as described above. A player is provided. In this media player, when various music data recording media as described above are connected to the vehicle-mounted audio device, in addition to simply playing and outputting various music, the data recorded on the connected music data recording medium is Search for data recorded in a format that can be played back by the media player, and track information such as artist name, album name in which the song is recorded, song name, genre name, etc. A database is created by collecting music information.

  For such music information, for example, for data recorded with mp3 or the like, it is possible to construct a database by reading tag data recorded along with each music data such as ID3 tag information. It is. By creating such a database of music information, it becomes possible for the user to select only the favorite music from among the music recorded on these data recording media at a high speed and view it in an arbitrary order. .

  An example of such an in-vehicle audio device is shown in FIG. 6A. In this figure, when a USB memory 52 is connected to an in-vehicle audio device 51 such as a head unit and this is reproduced by the media player 54, this is shown. The media player 54 searches for a compressed audio file that can be played back when the USB memory 52 is connected, and creates a database 53 for music information based on tag data such as an ID3 tag detected there. Thereafter, the media player 54 searches the music information recorded in the database, arbitrarily selects a desired music, creates a play list, etc., so that a favorite music can be reproduced continuously.

  An example of the music information database created in the database 53 at this time is shown in FIG. As shown in the figure, an example is shown in which file names, song names, album names, artist names, genre names, etc. exist as types of information in the database. In addition, the release year of the song, the required playback time, etc. as necessary Record. In the example shown in the figure, as the file name AAA.mp3... PQR.wma, in addition to the music compressed in the mp3 format, the music received the music distribution in the WMA (Window. Media Audio) format, etc. An example of recording is shown.

  By creating the database as described above, for example, in the example shown in FIG. 7, “album” is selected from the various types of music information shown in FIG. 7A and displayed as shown in FIG. “XXZ” is selected from the album names to be selected, and thereby, a specific song “YYY” is easily searched and selected from the songs included in the album name “XXZ” displayed as shown in (c). Can do.

Patent Document 1 discloses a technique for accelerating a search for a playlist file that needs to be corrected when digital content is deleted by storing playlist information referring to each digital content in a management file in a rewritable medium. Is disclosed.
JP 2007-53176 A

  In the conventional in-vehicle audio device 51 as shown in FIG. 6, when the USB memory 52 is connected as described above, the media player 54 can reproduce the music data recorded in the USB memory 52. The database 53 is created with respect to the data in the format. However, when the USB is removed thereafter, the created database is deleted, and when the USB memory is connected again, a database is newly created in the same manner. ing.

  However, for example, when the same USB memory is always used, creating a new database each time the USB memory is connected is good, for example, when the data recorded for the USB memory is significantly changed. When there is almost no change or even no change at all, useless processing is performed. When a large amount of music data of several gigabytes exists in the memory, the USB memory is connected and the database is stored by the above processing. It takes a lot of time to produce and complete, during which time the music data recorded in this memory cannot be reproduced.

  Therefore, when creating the database as described above, the ID of the USB memory is recorded in the created database, so that the database is maintained even after the USB memory is removed and the USB memory is connected again. It is conceivable that the database creation process is performed as described above only when it is determined that the database having the matching ID and the data in the connected USB memory are updated and updated.

  However, even in this case, the determination as to whether or not the in-vehicle audio device has been updated since the data in the connected USB memory was connected first compares the entire capacity or searches all files again. There is a need. In the method of re-searching all the files, it is necessary to search all the files again as a control every time the USB memory is connected. For example, when a large amount of music data such as 10,000 songs exists in the memory, Search alone takes a lot of time, and the performance of the in-vehicle audio system is suspected.

  Therefore, it is determined whether the data update is performed between the previous data and the current data by comparing the total capacity. However, with this method, when the artist name of a specific song is corrected in compressed audio such as MP3, only the ID3 tag data is updated, and the overall size does not change. . Therefore, in this method, it is impossible to determine whether or not the in-vehicle audio device database needs to be updated by updating the data in the USB memory.

  Even if it is detected that the data has been updated, there is no method for detecting how and for which music has been updated, so the database is created from the beginning, which takes time. Furthermore, even when, for example, image data other than the data to be reproduced by the media player of the in-vehicle audio device is added, the data amount of the USB memory changes, and at that time, it is determined that the data has been updated. Therefore, the database will be recreated.

  In order to solve such a problem, it is conceivable to record log data as a record in which data is updated in the USB memory. However, since the file update itself is performed on an arbitrary personal computer, it cannot be controlled by the in-vehicle audio apparatus. In addition, as is conventionally done, it is possible to install dedicated transfer software on a user's personal computer. However, this method requires the user to install application software for acquiring update data on the personal computer for the USB used by the vehicle audio device, which places a burden on the user and re-applies when the personal computer is changed. There is a problem that the user feels a troublesome audio device such as requiring installation.

  Therefore, according to the present invention, when the data in the memory is updated by a personal computer or the like, the data in the memory is updated when it is necessary to update the database about the data recorded in the memory. It is possible to easily detect what has been updated and which part has been updated without burdening the user, and to update only the part that needs to be updated in a short time. The main object is to provide an in-memory data update management system.

  In order to solve the above problems, an in-memory data update management system according to the present invention includes a data recording unit in a memory that records various data, and a specific type of data that can be processed by a device that uses the data in the memory. Data management software in the memory that performs processing for recording update information to which update identification information about the update data is added when it is detected that update has been performed, and memory record content update management created by the data management software In a device that uses a memory provided with data and uses the memory data, the memory record content update management data when the memory provided with the memory record content update management data to which the update identification information is added is connected to the device. To update the database of the device that uses the memory data and record the updated contents after the database update. And deletes the the memory recorded content update management data portion.

  Further, in another in-memory data update management system according to the present invention, in the in-memory data update management system, the update identification information is at least one of data addition, tag change, deletion, and movement. It is characterized by.

  Another in-memory data update management system according to the present invention is characterized in that, in the in-memory data update management system, the memory data using device is a vehicle-mounted audio device, and the memory is a USB memory. .

  In another in-memory data update management system according to the present invention, in the in-memory data update management system, the memory data utilization device is immediately recorded in a data recording unit in the memory when the memory is connected. It is characterized by taking in data information and performing database creation processing and update processing.

  Since the present invention is configured as described above, when the data in the memory is updated by a personal computer or the like, it is necessary to update the database about the data recorded in the memory created in the device using the memory. It is possible to easily detect that the data in the memory has been updated and which part has been updated without burdening the user, and only the parts that need to be updated in a short time. It will be possible to update.

  The purpose of the present invention is to create a database for the data in the memory when the memory is connected to the memory-using device, and to easily detect the update portion of the data in the memory and perform the update in a short time. When it is detected that a data recording unit in the memory to be recorded and a specific type of data that can be processed by the device using the data in the memory have been updated, update identification information about the update data is added. In a device using data management software in a memory for performing processing for recording update information and memory record content update management data created by the data management software, and using the memory data, the update identification information Memory record content update management data when a memory provided with the memory record content update management data is connected to the device. Updating the database of the device utilizing a memory data by chromatography data was achieved by removing the memory recording contents update management data portion that records the updated details when the database update.

  Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a schematic diagram of an in-memory data update management system according to the present invention. In the example shown in FIG. 1, a memory with data management software is provided as a memory of the present invention by providing data management software 5 in a USB memory. The example using what was set to "1" is shown.

  In other words, the memory used for recording music data includes a memory that only records data, such as a simple flash memory, and software in the memory such as a USB memory, and this memory is connected to a personal computer or the like. In some cases, there is a memory that automatically starts software and communicates with a personal computer or the like. In the present invention, such a software is provided in advance in the memory as a USB memory, and the software A memory 1 with data management software provided with an in-memory data update management unit 2 for performing update management of data recorded in the data recording unit 3 of the memory is used.

  The in-memory data update management unit 2 of the memory with data management software 1 includes the data management software 5 itself, and a data update monitoring unit 6 that monitors whether data in the data recording unit 3 is updated. It has. Further, when the data update monitoring unit 6 detects that the data is updated, an update for determining the type of data such as a data type indicating whether the updated data is image data or audio data, for example. A data type detection unit 7 is provided.

  In the update data type detection unit 7, for audio data, for example, there are various types of data besides WAV, MIDI, MP3, WMA, ATRAC, AAC. In the example of FIG. Since it is assumed that the memory data using device 21 is connected to the memory data using device 21 such as the head unit, when the memory data using device 21 supports mp3 and WMA in the audio data, the data management software 5 uses this mp3 in advance. It is determined whether or not the WMA type data is updated, and the subsequent processing is set.

  When the update data type detection unit 7 detects that the data to be updated is a predetermined type of preset data, the update identification information adding unit 8 adds, for example, data to the update data. Identification information corresponding to the update state, such as whether to change the record, delete the data, or move the data. The memory record update management data 9 is commonly called log data, and when a predetermined type of data is updated as described above, the state is recorded together with the update identification information.

  The data update monitoring unit 6 that monitors the update of the data, the update data type detection unit 7 that determines the type of the updated data, and the update identification information addition unit 8 are operated as software of the data management software 5. These functional units are shown as functions of the data management software 5.

  The memory 1 with data management software as described above can be sold at a general electric store like a normal memory. For example, a vehicle manufacturer can use it in an in-vehicle audio device installed in the company, or In order for manufacturers of on-board audio equipment to use their own audio equipment, create a memory by selecting the type of data that can be played back by media play on those audio equipment, and store this in various car parts stores, etc. Memory supply methods such as selling at

  The memory 1 with data management software as described above includes a connection unit 4 and is connected to a connection unit 14 of a personal computer shown as a user personal computer 11 directly or by wire. An example is shown in which the user personal computer 11 is provided with a data operation processing unit 12 for performing functions of a normal personal computer, and a data recording processing unit 13 for performing processing on a data recording medium such as an internal hard disk or an external memory.

  With such a user personal computer 11, various data recording processes are performed on the data recording unit 3 for storing a large amount of data in the memory 1 with memory management software. The update process of the memory data in the personal computer can be sequentially operated according to the operation flow shown in FIG. The memory data update process in the personal computer shown in FIG. 2 starts by first connecting the memory with data management software to the personal computer (step S1). This process is performed by connecting the connection unit 4 of the memory 1 with data management software in FIG. 1 and the connection unit 14 of the user personal computer 11.

  Next, the in-memory data management software is activated (step S2). This operation is performed when the memory 1 with data management software is connected to the user personal computer 11 by the connection unit 4 and the personal computer starts the data management software 5 of the in-memory data management unit 2 after recognizing the connection. Thereafter, it is determined whether or not the data in the memory is updated by the personal computer (step S3). If not updated, the process proceeds to step S7, whether or not the memory is removed from the personal computer is determined, and when it is removed, the process ends (step S8). ), And if not yet taken out, the process returns to step S3 again to repeat the above operation.

  When it is determined in step S3 that the data in the memory is updated by the personal computer, the data in the memory is updated (step S4), and it is determined whether or not the updated data is a specific type of data (step S5). In these operations, the data update monitoring unit 6 as a function of the data management software 5 in the in-memory data update management unit 2 in the memory 1 with data management software shown in FIG. The determination unit 7 determines whether the type of data to be updated is a predetermined type of data such as mp3 or WMA, for example.

  When it is determined that the data updated in step S5 is not a specific type of data, the process returns to step S3 again to repeat the operation. If it is detected that the updated data is a specific type of data, the process proceeds to step S6, and update identification information is added to the specific type of data to create recorded content update management data in the memory.

  The above operation is performed, for example, as shown in FIG. That is, in the example of update management data for the update contents in the memory with data management software shown in FIG. 4, the file name is “AAA.txt” first as shown in the table of update contents example in FIG. . The file type is a text file, the update contents to the USB memory as the memory with data management software are added, and the file path at that time is “/”, that is, the top of the data recording is “/” This text file indicates that the log data is not output because it is not mp3 or WMA to be reproduced by the memory data using device 21 such as the vehicle head unit as the specific device.

  Similarly, the second file name “YYY.mp3” is a compressed file, an update content to which data is added, and the file path of “/ \ music \ zxz”, that is, “music” on the root “/”. This indicates that log output is performed when the file type is “zxz” and the file type is mp3. In the following, an example is shown in which the file name, file type, USB update content, file path, and log output are also illustrated.

  In such an update content example, the management data as shown in FIG. 4B is recorded in the memory record content update management data 9 of FIG. 1 in the present invention. That is, in the example shown in the figure, the file with the file name “YYY.mp3”, which is the second update content in the update content example of (a), is recorded first and is recorded in the update identification information. Record “0x01” indicating “addition”. Further, it indicates that the file path is “/ \ music \ zxz” as described above.

  Thereafter, the file with the fourth file name “CCC.mp3” in the update content example of FIG. 4A is updated as “tag change” in the second data as shown in FIG. Thus, “0x02” data to that effect is recorded in the update identification information. The file path is “/ ¥ music ¥ best”. Similarly, “0x04” is recorded as the third file name “OPQ.wma” deleted, indicating that the file path no longer exists. In addition, “0x08” indicating that the file name “ZZZ.mp3” has been moved is recorded as the fourth, and “/ ¥ music” indicating that the file path has been moved from “/ ¥ music \ zzxz” to “/ ¥ music”. \ Zxz → / \ music ".

  In step S6 of FIG. 2, after the update identification information as described above is added to the specific type of data to create record content update management data in the memory, it is determined whether or not the memory is removed from the personal computer (step S6). S7) When it is determined that the data has not been removed yet, the process returns to step S3, and the operation is repeated after determining whether or not the data in the memory is updated by the personal computer. If it is determined in step S7 that the memory has been removed from the personal computer, this process is terminated (step S8).

  In FIG. 1 (a), after the process of updating the memory data in the personal computer by the process as described above, the memory 1 with data management software is removed from the personal computer 11 and this memory as shown in FIG. 1 (b). When the memory 1 with data management software is directly connected to the memory data using device 21, data processing is performed in the memory using device shown in FIG. That is, at the time of data processing in the memory using device shown in FIG. 3, it is first determined whether or not a memory with data management software is connected (step S11). Here, when it is determined that the connection has not been made, this operation is repeated to wait.

  If it is determined in step S11 that a memory with data management software is connected, it is determined whether or not recorded content update management data with update identification information exists in the memory (step S12). In this process, when the memory 1 with data management software is connected to the connection unit 24 in the memory data utilization device 21 in FIG. 1B, the update identification information addition management data fetching unit 23 performs the memory record content update management data 9. This can be done by detecting whether or not the update identification information added by the update identification information adding unit 8 exists.

  Here, when it is determined that the record content update management data with update identification information as described above exists in the memory, that is, the data updated by the personal computer in step S5 in the operation flow of FIG. 2 is used by this memory. 3, it is determined that the data relates to a specific type of data to be reproduced, and update identification information is added in step S6 to create record content update management data in the memory. Then, it is determined whether or not the recorded content update management data exists in the memory, and if it is determined that it exists, the database in the device is updated by the recorded content update management data (step S13). ).

  This update process can be easily performed by the database creation processing unit 26 in the memory data utilization device 21 of FIG. 1 using the update management data with update identification information as shown in FIG. If it is determined in step S12 that there is no management data with update identification information, the process proceeds to step S16 to perform database use processing described later.

  Thereafter, in step S14, it is determined whether or not the update process has been completed. If it has not been completed yet, the update process in step S13 is continued. If it is determined that the update process has been completed, the updated record content update management data is erased. (Step S15). As a result, a large number of update processes are repeatedly performed in the memory with the data management software, so that the memory record content update management data to which the update identification information as described above is added increases, and the memory capacity portion for performing normal data recording To prevent the decrease.

  Thereafter, various processes using the database are performed (step S17), and thereafter, the normal operation of the memory with the data management software in the memory using device is performed. Here, for example, when the memory-using device is a vehicle-mounted head unit, as shown in FIG. 7, the audio data recorded in the data recording unit 3 in FIG. 1 is used as various processes using the database in step S16. Then, a specific album is selected from the album name, a desired song is selected from the album, and thereafter, reproduction processing in various modes such as reproduction, stop, and fast-forward of data in the data recording unit 3 by the user is performed. This processing can be performed using the database 27 as described above in the database usage processing unit 25 in the memory data usage device 21 of FIG.

  Next, it is determined whether or not the memory has been removed from the device (step S17). When the memory has not been removed, the various processes in step S16 are continued. If it is determined that the data has been extracted, the process proceeds to step S18 to end the series of processes.

  In the embodiment, the in-memory data update management unit 2 in the memory 1 with data management software of FIG. 1 includes the data management software 5 for performing the various processes as described above, and the operation mode of the data management software 5 In this example, the data update monitoring unit 6, the update data type detection unit 7, and the update identification information addition unit 8 are provided. However, since the functions of these data management software are actually performed by the user personal computer 11, for example, FIG. As shown in a), these can be regarded as processing in the user personal computer 11 performed by the data management software 5. The memory 1 with data management software having such a functional configuration can also be connected to the memory data utilization device 21 as shown in FIG.
