Of course, this description does not mean that each means is limited to those described above.

FIG. 1 is a block diagram showing a configuration example of a music distribution system to which the information distribution system of the present invention is applied.

In the terminal 1 on the user side, the user interface unit 2 has, for example, a keyboard, a mouse or a tablet as an input device, and has a CRT or LCD as an output device, so that the user can perform a predetermined key operation. By doing so, the operation of the terminal 1 can be controlled. Also, the index information supplied from the server 11 is displayed on the screen of a CRT, LCD or the like. The IDX detection unit 3 reads the index information corresponding to the data recorded on the MD medium 5, and transmits it to the server 11 on the provider side via the communication control unit 7 and the bidirectional communication path 21. There is.

When the IDX recording unit 4 receives via the communication control unit 7 the update information of the index information transmitted from the provider side via the bidirectional communication path 21, the IDX recording unit 4 stores it in the MD medium 5 based on the received update information. On the other hand, the index information is updated. In addition, the data recording unit 6
When the new data transmitted from the provider side via the bidirectional communication path 21 is received via the communication control unit 7, the new data is recorded in the MD medium 5 and the data is updated. ing.

The MD medium 5 is adapted to record music data and its index information here.
The IDX recording unit 4 records or updates the index information, and the data recording unit 6 records or updates the data.

The communication control section 7 controls the communication with the server 11 via the bidirectional communication path 21.

In the server 11 on the provider side, the database 15 stores, for example, data of music such as the Oricon top 10 and index information corresponding thereto, and the index information is always arranged in the order of popular music. It is designed to be updated. The IDX comparison unit 12 uses the bidirectional communication path 2 from the user side.
1 is received via the communication control unit 18 and is compared with the index information of the data recorded in the database 15 described later to be recorded in the MD medium 5 of the terminal 1. The data stored in the database 15 and the data stored in the database 15 are compared with each other.

For example, when music data for 10 songs is recorded on the MD medium 5, index information corresponding to the music data for the 10 songs and the top 10 of the music data recorded in the database 15 are recorded. The index information of the music data corresponding to the song (for example, 10 songs of Oricon Top 10) is compared.

The IDX rewrite control unit 14 reads the index information from the database 15 and rewrites the index information of the terminal 1 when the index information of the terminal 1 needs to be updated based on the comparison result of the IDX comparison unit 12. The update information is generated and supplied to the IDX rewriting unit 13. For example, if the index information from the IDX detection unit 3 and the index information read from the database 15 have the same index forming the index information and only the order is different, the IDX rewrite control unit 14 rearranges the indexes. To the IDX rewriting unit 13. Further, when the index information from the IDX detection unit 3 does not include at least one of the indexes forming the index information read from the database 15, the index information read from the database 15 is directly used as the index information. I as update information
It is supplied to the DX rewriting unit 13.

The IDX rewriting unit 13 is adapted to transmit the index update information supplied from the IDX rewriting control unit 14 to the terminal 1 via the communication control unit 18 and the bidirectional communication path 21.

The data update control unit 16 includes the IDX comparison unit 1
On the basis of the comparison result according to No. 2, music data which is in the index information of the database 15 but not in the index information of the MD medium 5 of the terminal 1 is read from the database 15 and is transmitted via the communication controller 18 and the bidirectional communication path 21 to the terminal 1 It is designed to be sent to.

The communication control unit 18 controls the communication with the terminal 1 via the bidirectional communication path 21.

Next, the operation will be described with reference to FIG. First, in step 1, the user operates the user interface unit 2 to select, for example, one of the selection items “automatic” and “selection” displayed on the LCD screen. That is, the data recorded on the MD medium 5 of the terminal 1 is stored in the database 1 on the provider side.
It is specified whether the updating process is automatically performed according to the data stored in 5, or the user selects the updating data.

The user interface unit 2 is operated,
When "automatic" is selected, the process proceeds to step S2, and the IDX detection unit 3 of the terminal 1 detects the index of the data recorded on the MD medium 5. First, the index information is read from the MD medium 5 and transmitted to the server 11 on the provider side via the communication control unit 7 and the bidirectional communication path 21.

For example, as shown in FIG. 3, the MD medium 5 has recorded therein the index and data of each music of the Oricon top 10. Each index indicates the recording location of the music data corresponding to the index. It holds the indicated address information. The order in which the indexes are arranged represents the ranking, and in this case, the music A is the most popular music right now.

Next, in step S3, the IDX comparison unit 12 of the server 11 on the provider side first sends the MD from the IDX detection unit 3 of the terminal 1 via the communication control unit 7 and the bidirectional communication path 21. The index information of the medium 5 is received via the communication control unit 18. Next, the IDX comparison unit 12 reads out the index information corresponding to the top 10 songs of the data recorded therein, for example, the 10 songs of the Oricon top 10, from the database 15, and receives this index information and the received first. I
The index information of the MD medium 5 from the DX detector 3 is compared. That is, it is compared whether or not the index information of the MD medium 5 includes all of the indexes that form the index information read from the database 15.

In step S4, the IDX comparison unit 1
Based on the comparison result of No. 2, it is determined whether the MD medium 5 has (includes) all the indexes forming the index information of the database 15. When it is determined that the MD medium 5 has all the indexes forming the index information of the database 15, step S
Go to 5.

In step S5, first, the IDX rewrite control unit 14 orders the indexes recorded in the MD medium 5 and the indexes recorded in the database 15 based on the comparison result by the IDX comparison unit 12. Are determined to be equal, and if the orders are equal, no processing is performed and the processing ends.

On the other hand, if it is determined that the order of the indexes recorded in the MD medium 5 and the order of the indexes of the top 10 songs recorded in the database 15 are not equal, the IDX rewrite control section 14 determines that the MD medium is in the MD medium. The information for rearranging the order of the indexes recorded in No. 5 into the order of the indexes of the top 10 songs recorded in the database 15 is ID as the index update information.
It is supplied to the X rewriting unit 13.

As the index update information, the indexes corresponding to the top 10 songs of the database 15 can be used as they are, for example, MD.
The index update information indicates that the first index recorded on the medium 5 is the second after the update, the second index is the first after the update, and the third index is the fifth after the update. Can also be

The IDX rewriting unit 13 sends the index update information supplied from the IDX rewriting control unit 14 to the ID of the terminal 1 via the communication control unit 18 and the bidirectional communication path 21.
It is transmitted to the X recording unit 4. When the IDX recording unit 4 receives the index update information from the IDX rewriting unit 13 via the communication control unit 7, the index of the MD medium 5 is recorded in the database 10 based on the index update information. The indexes of the MD medium 5 are rewritten so that the indexes of the song data are arranged in order. That is, the order of the indexes is exchanged.

Thus, for example, as shown in FIG. 4, the order of the indexes recorded on the MD medium 5 is rewritten so that the order of the indexes recorded on the database 15 is the same. . In this case, the order of music B, C, D, E, G, and H has been rewritten. Since each index is associated with the address on the MD medium 5 in which the data corresponding to the index is recorded, it can be considered that the data is rearranged in the order of the rewritten index.

On the other hand, in step S4, the MD medium 5
The top 1 of the database 15 in the index information of
When it is determined that at least one of the indexes corresponding to the data of 0 songs is not included, step S
In step 10, the index information of the MD medium 5 is updated, and data is added or deleted, as will be described later. For example, index re-editing and overwriting of new data are performed. At this time,
The music data newly charted into the Oricon Top 10 is overwritten as the new chart data.

FIG. 5 shows this state. In this case, music K is newly charted in, ranked first, and music J, which has been in the top 10 until now, is charted out. The newly charted music K is overwritten at the place where the charted out music J was recorded.

When the indexes are rearranged or the indexes are updated and the data is added, the charging processing unit 17 performs the charging processing on the terminal 1.

After that, the processing is terminated.

When the user selects the selection item "selection" in step S1, the process proceeds to step S6.
In step S6, first, the terminal 1 notifies the provider side that the user has instructed "selection". As a result, the server 11 on the provider side transmits the index information corresponding to the data of the top 10 songs recorded in the database 15 to the terminal 1 via the communication control unit 18 and the bidirectional communication path 21. When the terminal 1 receives this index information from the server 11, characters or the like corresponding to the index information are displayed on the screen of the LCD or the like constituting the user interface unit 2.

Next, in step S7, the user
The index of the data recorded in the database 15 displayed on the LCD screen of the user interface unit 2 of the terminal 1 is checked, and the index of one or more desired data to be recorded in the MD medium 5 is selected from the indexes. Select by operating the keyboard. In step S8, it is determined whether or not all the indexes selected by the user in step S7 already exist in the MD medium 5 of the terminal 1.

If it is determined that all the indexes selected by the user already exist in the MD medium 5 of the terminal 1, the process proceeds to step S9, and the index order of the MD medium 5 is rewritten to the index order of the database 15. The user is inquired via the user interface 2 as to whether or not to ask. If the user has instructed to rewrite the order of the indexes, the process proceeds to step S5, and the IDX recording unit 4 proceeds to M as in the case described above.
The order of the indexes of the D medium 5 is rewritten so as to be the same as the order of the indexes recorded in the database 15. On the other hand, when the user instructs not to rewrite the order of the indexes, the process ends.

In step S8, step S
If it is determined in step 7 that at least one of the indexes selected by the user is not recorded on the MD medium 5, the process proceeds to step S10, and the index information is updated and data is added or deleted.

That is, the server 11 on the provider side sets the index update information to I in order to update the index of the data recorded on the MD medium 5 of the terminal 1 on the user side.
The DX rewriting unit 13 transmits the data to be added to the terminal 1 via the communication control unit 18 and the bidirectional communication path 21, and the data to be newly added from the data update control unit 16 via the communication control unit 18 and the bidirectional communication path 21. And sends it to the terminal 1.

When the IDX recording unit 4 of the terminal 1 receives the index update information from the IDX rewriting unit 13 of the server 11 via the communication control unit 7, the index information of the MD medium 5 is stored on the basis of the index update information. Rewrite. Further, the data recording unit 6 of the terminal 1 is the server 11
When new data is received from the data update control unit 16 via the communication control unit 7, it is recorded on the MD medium 5. At this time, new data can be overwritten, for example, on the data recorded on the MD medium 5 to the data charted out from the Oricon top 10. This makes it possible to add data to be charted in and delete data to be charted out.

Further, when at least one of the index and the data recorded on the MD medium 5 is updated, the charging processing section 17 can perform a predetermined charging processing for the terminal 1. In this charging process, for example, different amounts of money can be charged depending on whether the index is rewritten or the new data is added and updated.

Information relating to this charging is provided to the bidirectional communication path 2
By sending to the terminal 1 on the user side via 1,
The current charging status can be notified to the user. It is also possible to transmit the charging information to a credit card company or a bank so that the amount of money corresponding to the charging will be deducted from the user's account.

As described above, the user can receive distribution of music data such as the Oricon top 10 with a simple operation. Further, when only the ranking changes, only the index needs to be changed, the amount of data transmitted by the server 11 via the bidirectional communication path 21 can be reduced, and music data can be efficiently distributed. be able to.

After that, the processing ends.

As described above, when only the order of the music data is changed, only the index is changed. Therefore, as the recording medium on the user side for recording the music data distributed from the provider side, as described above, the MD medium is used. It is efficient to use a disc-shaped recording medium capable of random access for managing data by an index such as. Of course, it is not limited to a disc such as an MD, and any disc that can be randomly accessed and can manage data by an index may be used.

In the above embodiment, the target data was described as music data, but the data is not limited to this, and it may be game software or other data.

Further, in the above embodiment, the data is recorded on the MD medium, but the present invention is not limited to this, and it is also possible to record the data on another recording medium.
