4. The conversion process in the conversion server 1 (center) will be described with reference to the flowchart in FIG. 7.

[4.1 When Obtaining Free Content] In the following, it is desired to access the content server from the user terminal of the model code KD201 and distribute the content whose title is "newcomer promotion". However, the case where data distribution cannot be performed will be described because they are different.

From the user terminal to the conversion server, the user
A request for distribution of the content “new face promotion” is made (step S1 in FIG. 7). The conversion server identifies the terminal specifications by referring to the model code included in the header information of the request (step S11). In this case, the model code KD201 is specified.

Next, the conversion server determines the composition of the composite content based on the advertisement specifying rule (step S1).
3). As the configuration of the composite content, in the present embodiment, the advertisement data to be combined with the designated content is specified. In addition, as an advertisement identification rule,
In the present embodiment, the lowest price of the advertisement data having a price higher than the conversion charge of the conversion target content is selected. In this case, since the conversion charge for the content "new face promotion" is 10 yen, the management number A
The advertisement of 002 "movie digest (3 seconds without regulation)" is determined.

It should be noted that the advertisement specifying rule may be separately stored and the decision may be made based on the rule.
For example, divide content and advertisements by field,
For example, the size of the data amount of the advertisement data may be prioritized by selecting the same field, considering the frequency, the elapsed time from the last adoption, and the like.

Further, the advertisement specifying rule may store a rule for determining the advertisement insertion timing, the insertion time, the screen ratio between the advertisement and the content, and the like so that the same can be specified. For example, with respect to the timing of inserting an advertisement, it may be considered that a blank time may occur if it takes time to receive the data from the content server.
In this case, text data may be delivered as it is. This allows the data to flow without interruption.

The CPU 23 refers to the content database, and designates the designated title "new face promotion".
The storage location of is specified and a content distribution request is transmitted (step S15). Further, the CPU 23 refers to the advertisement index database, specifies the storage location of the determined advertisement, and transmits a distribution request for advertisement data (step S17). The content server and the advertisement server respectively transmit the requested data (step S41,
Step S43).

If the distributed content data and / or advertisement data is encoded, the CPU 23 decodes it and mixes it (mixing) (step S19). It should be noted that in the present embodiment, the data conversion unit 34 does not perform the data format encoding and decoding processing by the CPU 23. In this case, since the data formats are the AVI format and the Real format, they are decoded and combined. Even if the data formats are the same, the decoding process is performed once. Because it is necessary to combine them. As a result, uninterrupted data can be delivered.

The CPU 23 encodes the data merged in step S19 into the data format of the terminal based on the terminal specifications determined in step S11 (step S).
21). In this case, since the data format of the user terminal with the model code KD201 is "MPEG4", the user terminal is converted to such a format.

The screen size of the terminal is 256 * 12.
8, the screen size of the content is 400 * 320. Therefore, a predetermined size adjustment may be performed. Further, the compression rate may be adjusted (higher or lower) as appropriate in consideration of the communication speed of the terminal.

Then, the CPU 23 delivers the encoded data to the user terminal (step S23).

The user terminal displays the content data combined with the advertisement (step S3).

On the other hand, in the conversion server, the CPU 23 stores the distribution result as an advertisement history (step S25).
In this case, the fact that the advertisement with the management number A002 has been distributed is stored. The CPU 23 collects such history for each advertisement server, generates a monthly distribution log, and transmits this to each advertisement server (step S29).

In this way, the user terminal can acquire the content data in the data format adopted by the user terminal even if the data format of the content server does not match the data format of the user terminal. it can.

Also, since the advertisement is combined with the content data and transmitted at the time of the conversion, the advertisement server can perform efficient advertisement.

Also, the conversion fee (service fee) of the conversion server
With regard to the above, since the side providing the advertisement bears the burden, the data conversion processing can be performed without burdening the user.

As described above, in this embodiment, when the data format of the computer of the content provider is different from the data format of the computer of the content user, the decoding process is performed once. The inventor has focused on such decoding processing. That is, it is often difficult to combine encoded data even if they have the same data format, especially when the data formats are different. However, it is easy to combine other data as long as it is decoded data. Therefore, it is intended to combine the advertisement data with this so that the data can be distributed without requiring a new conversion process and without burdening the user with such a conversion process fee.

In the above embodiment, the case where the content data is free has been described as an example, but the same can be applied when the content data is charged. Processing when the content data is charged will be described with reference to FIG.

[4.2 Case of Obtaining Paid Content] In the following, the content server is accessed from the user terminal of the model code KD201, and the distribution of the content whose title is "Today's home run" is requested.
The case where the data distribution cannot be received because the data format is different and the content price is charged will be described.

From the user terminal to the conversion server, the user
A distribution request for the content "Today's Home Run" is made (step S101 in FIG. 8). The conversion server refers to the model code included in the header information of the request to identify the terminal specifications (step S111).

Next, the conversion server determines the composition of the composite content based on the advertisement specifying rule (step S11).
3). In this case, in the same manner as described above, the content "Today's Home Run" has a price of 30 yen and a conversion fee of 20 yen, so that an advertisement with a total of 50 yen or more is determined. If there is no advertisement that satisfies the conditions in one advertisement, a plurality of advertisements may be combined. In this case, if the 100 * 100, 5 second advertisement with the management number A001 and the two advertisements with the management number A003 are combined, the total is 55 yen, which satisfies the content fee and the conversion fee. Therefore, this is selected.

The CPU 23 refers to the content database, specifies the storage location of the designated title "Today's home run", and transmits a content distribution request (step S115). Further, the CPU 23 refers to the advertisement index database, specifies the storage location of the determined advertisement, and transmits a distribution request for advertisement data (steps S117 and S118). The content server and the advertisement server respectively transmit the requested data (steps S141, S143, S145).

If the distributed content data and / or advertisement data is encoded, the CPU 23 decodes it and mixes it (mixing) (step S119). In this case, since the data format is the Real format and the text format, the advertisement data in the text format is not decrypted. Then, the three data are combined.

The CPU 23 encodes the data combined in step S119 into the data format of the terminal based on the terminal specifications determined in step S111 (step S121). Then, the CPU 23 delivers the encoded data to the user terminal (step S123).

The user terminal displays the content data combined with the advertisement (step S103).

On the other hand, in the conversion server, the CPU 23 stores the distribution result as an advertisement history (step S12).
5). In this case, management numbers A001 and A003
Remember that you've delivered your ad. The CPU 23 collects such history for each advertisement server, generates a monthly distribution log, and transmits this to each advertisement server (step S12).
9).

The CPU 23 stores it as a distribution history of pay contents (step S131). CPU23
The delivery history is collected for each content server, a monthly delivery log is generated, and the fee to be paid is determined (step S133).

In this way, the user terminal can acquire the content data in the data format adopted by the user terminal, even for paid content, free of charge.

5. Other Embodiments In this embodiment, the distribution request for the title “new face promotion” is given from the user terminal, but the title of the content database shown in FIG. The user may be allowed to select the content.

In the above embodiment, the user terminal once accesses the content server, and when the access is not established, the conversion server is accessed to request the data conversion and delivery. However, the present invention is not limited to this, and the conversion server may be accessed from the beginning and any one of the content data that can be distributed via the conversion server may be selected.

In the above embodiment, the moving image content is described as an example of valuable value data, but other content data such as still image content may be used. The same applies to various application programs such as games and music data.

In the above embodiment, the case where the mobile phone with the browser function is adopted as the user terminal has been described, but a mobile terminal such as a notebook computer or PDA may be used.

In the above-described embodiment, the case where the conversion work fee for valuable value data is offset with the advertisement fee to perform the data distribution has been described. However, the entire amount is not offset with the advertisement fee, but a part of the user fee is used. You may make it a burden.

The valuable value data is not limited to the content data recorded in the content server, but may be real-time concert relay, traffic jam information, university lecture, live broadcasting, or the like. Further, it may be image and audio information of a videophone or the like.

Further, advertisements in fields of interest may be combined according to the taste of the user. In this case, not only may the questionnaire be taken and stored in advance by the user, but the judgment may be made from the history of what kind of site is being referred to.

Further, although TCP / IP and UDP / IP are adopted as the communication protocols in this embodiment, other communication protocols may be adopted.

In the present embodiment, in order to realize the functions shown in FIG. 2, a CPU is used and this is realized by software. However, some or all of it
It may be realized by hardware such as a logic circuit.

Further, part of the processing of the program is further
You may make it an operating system (OS).
