<First Embodiment>
[Outline of data reproduction system S1]
FIG. 1 is a diagram showing a configuration of a data reproduction system S1 according to the first embodiment. The data reproduction system S1 is a system for distributing a program broadcast by a broadcasting station via the Internet M. A user can view a program distributed on the Internet N using a data reproduction terminal 3 such as a smartphone.

The data reproduction system S1 includes a broadcasting device 1, a data distribution device 2, a data reproduction terminal 3, and an advertisement server 4.
The broadcast apparatus 1 is an apparatus for distributing a broadcast program installed in a broadcast station. Although details will be described later, the broadcasting device 1 broadcasts the program content by inserting an advertisement (hereinafter referred to as a first advertisement) into the main data. In this specification, “main part” refers to a part other than an advertisement in a broadcast program, and “main part data” refers to data of the main part. The main data includes at least one of audio data and image data.

  The broadcast apparatus 1 broadcasts the produced program content by outputting it to the broadcast network B. The broadcast device 1 outputs the program content to the broadcast network B, so that the user can view the program content on the radio or television. Also, the broadcasting device 1 inputs the program content to the data distribution device 2 in order to distribute the program content via the Internet N.

  The data distribution device 2 creates distribution data for distribution over the Internet N based on the program content input from the broadcast device 1. Specifically, the data distribution apparatus 2 extracts the main part from the program content input from the broadcasting apparatus 1 and specifies the timing at which the advertisement is inserted. The data distribution device 2 encodes the main data into digital data to generate program data, and generates start timing information indicating the start timing of the advertisement period (for example, 60 seconds) in which the advertisement is inserted. Then, the data distribution device 2 transmits distribution data including a plurality of generated program data and timing information to the Internet N.

  Here, one program data includes encoded data corresponding to continuous main data. The data distribution device 2 transmits, for example, first program data corresponding to the main part broadcasted before the first advertisement and second program data corresponding to the main part broadcasted after the first advertisement.

  The data reproduction terminal 3 is a communication terminal such as a smartphone and a tablet. The data reproduction terminal 3 receives the distribution data transmitted from the data distribution device 2 via the Internet N, and reproduces a plurality of program data included in the received distribution data. At this time, the data reproduction terminal 3 acquires an advertisement (hereinafter referred to as a second advertisement) to be inserted into an advertisement period starting from the start timing indicated by the start timing information, which is a period between a plurality of program data, from the advertisement server 4. . The second advertisement acquired by the data reproduction terminal 3 from the advertisement server 4 is an advertisement different from the first advertisement inserted when the broadcasting device 1 broadcasts via the broadcast network B.

  The data reproduction terminal 3 acquires the second advertisement from the advertisement server 4 in response to the user performing an operation for reproducing the distribution data. The data reproduction terminal 3 reproduces the second advertisement at the start timing during reproduction of the program data.

  The data reproduction terminal 3 acquires, for example, the second advertisement selected based on the user attribute of the data reproduction terminal 3 from the advertisement server 4. As described above, the data reproduction terminal 3 acquires a second advertisement different from the first advertisement inserted when the broadcasting device 1 broadcasts, and thus is suitable for the user as compared with the case where the first advertisement is reproduced as it is. Since there is a high probability that an advertisement with the same content can be reproduced, the effect of the advertisement can be increased.

  FIG. 2 is a conceptual diagram of broadcast data output from the broadcast apparatus 1, distribution data distributed by the data distribution apparatus 2 via the Internet N, and reproduction data reproduced by the data reproduction terminal 3. In the broadcast data shown in FIG. 2A, the first advertisement is inserted between a plurality of main data. The main data may be live broadcast data or recorded data.

In the distribution data shown in FIG. 2B, the first advertisement is deleted from the broadcast data shown in FIG. 2A, and the start timing of the advertisement period in which the first advertisement is inserted instead of the first advertisement is shown. The start timing information shown is added. The distribution data includes program data in which the main data is encoded. In addition, in the delivery data, not only the start timing information but also end timing information indicating the end timing of the advertisement period in which the first advertisement has been inserted, or a period indicating the length of the advertisement period in which the first advertisement has been inserted Information may be added.
Hereinafter, the configuration and operation of the broadcasting device 1, the data distribution device 2, and the data reproduction terminal 3 will be described in detail.

[Configuration of Broadcasting Device 1 and Data Distribution Device 2]
FIG. 3 is a diagram illustrating the configuration of the broadcasting device 1 and the data distribution device 2.
The main data and the advertisement data of the first advertisement are input to the broadcasting device 1. The main data input to the broadcasting device 1 is, for example, voice data produced by performers such as actors or announcers, and data of performer images (either still images or moving images). The advertisement data input to the broadcasting device 1 is selected in order from a large number of advertisement data stored in advance.

  The broadcast device 1 includes a switching unit 11 and a timing information generation unit 12. The switching unit 11 is a switch for the broadcast device 1 to switch between the main data and the advertisement data. When the program producer operates the switching unit 11 while the broadcast device 1 is outputting the main data, the broadcast device 1 stops outputting the main data to the broadcast network B and outputs the advertisement data. Start. When the program producer operates the switching unit 11 again, the broadcasting device 1 stops outputting the advertisement data and resumes outputting the main data.

  The timing information generation unit 12 generates start timing information indicating the start timing of the period in which the advertisement data of the first advertisement is inserted based on the timing at which the program producer operates the switching unit 11. The timing information generation unit 12 inputs the generated start timing information to the data distribution device 2.

The data distribution device 2 includes a data acquisition unit 21, a timing information acquisition unit 22, a distribution data generation unit 23, and a distribution unit 24.
The data acquisition unit 21 acquires the main data broadcast from the broadcast program 1 from the broadcast device 1. The data acquisition unit 21 acquires, for example, analog audio data broadcast from a broadcast program from the broadcast device 1. The data acquisition unit 21 inputs the acquired analog data to the distribution data generation unit 23.

  The timing information acquisition unit 22 acquires from the broadcasting device 1 start timing information indicating the start timing of the period in which the first advertisement is inserted when the broadcast program is broadcast. The timing information acquisition unit 22 inputs the acquired start timing information to the distribution data generation unit 23.

  The distribution data generation unit 23 encodes the main data acquired from the data acquisition unit 21 and multiplexes the start timing information acquired by the timing information acquisition unit 22 with the encoded program data, thereby generating distribution data. Generate. For example, the distribution data generation unit 23 adds start timing information indicating the start time of the advertisement period in which the first advertisement is inserted as meta information of the program file including the program data. The distribution data generation unit 23 adds start timing information indicating start times of a plurality of first advertisements, end timing information indicating end times, and period information indicating a period during which the first advertisements are inserted as meta information to the program file. May be. The above-mentioned start timing information, end timing information, and period information can be based on the start time of program data, for example.

  The distribution unit 24 distributes the distribution data generated by the distribution data generation unit 23 to the data reproduction terminal 3 by transmitting it to the Internet N. The distribution unit 24 includes a LAN (Local Area Network) controller as a communication interface for transmitting distribution data to the Internet N, for example.

[Configuration of Data Reproducing Terminal 3]
FIG. 4 is a diagram showing a configuration of the data reproduction terminal 3. The data reproduction terminal 3 includes a communication unit 31, a storage unit 32, a control unit 33, a speaker 34, and a display 35. The control unit 33 is a CPU (Central Processing Unit), for example, and functions as a data acquisition unit 331, an advertisement acquisition unit 332, and a data reproduction unit 333 by executing a program stored in the storage unit 32.

  The communication unit 31 has a communication interface for accessing the Internet N via a mobile phone network. The communication unit 31 has, for example, a wireless module, and acquires distribution data distributed from the data distribution device 2 via a wireless line. The communication unit 31 inputs the received distribution data to the data acquisition unit 331.

  Further, the communication unit 31 transmits a message requesting the second advertisement to the advertisement server 4 based on the instruction from the advertisement acquisition unit 332, and receives the second advertisement data corresponding to the transmitted message. The communication unit 31 inputs the received second advertisement data to the advertisement acquisition unit 332.

  The storage unit 32 includes a storage medium such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 32 stores a data reproduction program executed by the control unit 33. The storage unit 32 stores attribute information indicating the attributes of the user of the data reproduction terminal 3. The attribute information includes, for example, information indicating the characteristics of the user, such as the user's gender, age, place of residence, work place, occupation. Furthermore, the storage unit 32 temporarily stores the second advertisement acquired by the advertisement acquisition unit 332 until the data reproduction unit 333 reproduces it.

  The data acquisition unit 331 acquires the distribution data output from the data distribution device 2 via the communication unit 31. Specifically, the data acquisition unit 331 acquires program data broadcasted in a broadcast program, start timing information, and end timing information or period information. The data acquisition unit 331 inputs the acquired program data to the storage unit 32. Further, the data acquisition unit 331 inputs the acquired start timing information and end timing information or period information to the advertisement acquisition unit 332 and the data reproduction unit 333.

  The advertisement acquisition unit 332 acquires the start timing information from the data acquisition unit 331, and acquires the second advertisement from the advertisement server 4 at a timing before the start timing indicated by the start timing information. Specifically, the advertisement acquisition unit 332 requests the second advertisement from the advertisement server 4 and acquires the second advertisement data transmitted by the advertisement server 4 in response to the request. The advertisement acquisition unit 332 temporarily stores the acquired second advertisement data in the storage unit 32.

  Here, the advertisement acquisition unit 332 may read the attribute information stored in the storage unit 32 and acquire the second advertisement corresponding to the attribute of the user of the data reproduction terminal 3 from the advertisement server 4. For example, when the user of the data reproduction terminal 3 is a woman in his twenties, the advertisement acquisition unit 332 acquires an advertisement related to cosmetics for young women. By doing in this way, compared with the case where the 1st advertisement carried by the broadcast program is used as it is, the user can hear an advertisement with a strong appeal to the user of the data reproduction terminal 3, so the effect of the advertisement can be improved. Can be increased.

  The advertisement acquisition unit 332 acquires period information indicating the length of the advertisement period in which the first advertisement included in the distribution data is inserted, and sends a second advertisement corresponding to the length indicated by the period information from the advertisement server 4. You may get it. Specifically, the advertisement acquisition unit 332 notifies the advertisement server 4 of the length indicated by the period information, and among advertisements of various lengths managed by the advertisement server 4, the length of the advertisement period indicated by the period information An advertisement having a length matching the length is acquired as the second advertisement.

  The advertisement acquisition unit 332 may acquire a plurality of advertisements shorter than the length indicated by the period information as the second advertisement. In this case, the advertisement acquisition unit 332 adjusts the length of the advertisement requested to the advertisement server 4 so that the total length of the plurality of advertisements becomes the length indicated by the period information. When the data acquisition unit 331 acquires the end timing information, the advertisement acquisition unit 332 may determine the length of the advertisement to be acquired based on the advertisement period specified based on the start timing information and the end timing information. .

  The data reproduction unit 333 reproduces program data by inserting the second advertisement in the advertisement period starting from the start timing indicated by the start timing information distributed by the data distribution device 2. For example, the data reproduction unit 333 stores the second advertisement having a length corresponding to the advertisement period indicated by the period information, starting from the start timing after reproducing the first program data of the main part distributed by the data distribution device 2. Read from 32 and play. When the reproduction of the second advertisement data is completed, the data reproduction unit 333 starts reproduction of the second program data of the main part.

  When the program data and the second advertisement include encoded audio data, the data reproduction unit 333 reproduces the program data and audio data by decoding the audio data and outputting the decoded data to the speaker 34. When the program data and the second advertisement include encoded image data, the data reproduction unit 333 reproduces the program data and the image data by decoding the image data and outputting the decoded image data to the display 35.

  The data reproducing unit 333 may reproduce the number of second advertisements different from the number of first advertisements within a period in which the first advertisement is inserted in the broadcast program. For example, when the advertisement acquisition unit 332 acquires a plurality of advertisements shorter than the advertisement period indicated by the period information as the second advertisement, the data reproduction unit 333 inserts a plurality of second advertisements shorter than the period indicated by the period information. Program data is reproduced. Conversely, the data reproduction unit 333 may reproduce the second advertisement longer than each of the first advertisements within a period in which the plurality of first advertisements are inserted in the broadcast program.

  In addition, when the length of the second advertisement acquired by the advertisement acquisition unit 332 is shorter than the period indicated by the period information, the data reproduction unit 333 stores the data reproduction unit 333 in the storage unit 32 in advance before or after the second advertisement. The stored predetermined information may be reproduced. For example, when there is no second advertisement that matches the length of the period indicated by the period information, the data reproduction unit 333 reproduces the second advertisement that is shorter than the period indicated by the period information, and then is stored in the storage unit 32. Play BGM (Back Ground Music). By doing in this way, it is possible to avoid the occurrence of a blank period even when there is no second advertisement having an appropriate length.

[Flow of processing in data reproduction system S1]
FIG. 5 is a sequence diagram showing the flow of processing in the data reproduction system S1.
First, in the data distribution device 2, the data acquisition unit 21 acquires the main data from the broadcasting device 1 (S11). Subsequently, the timing information acquisition unit 22 acquires start timing information from the broadcasting device 1 (S12). The distribution data generation unit 23 multiplexes the program data obtained by encoding the main data and the start timing information, and generates distribution data (S13). Distribution data generated by the data distribution apparatus 2 is input to the data reproduction terminal 3 via the Internet N.

  In the data reproduction terminal 3, the data acquisition unit 331 acquires distribution data, and extracts program data and start timing information from the acquired distribution data (S14). In response to the acquisition of the distribution data, the advertisement acquisition unit 332 transmits attribute information indicating the attribute of the user of the data reproduction terminal 3 to the advertisement server 4 before the start timing indicated by the start timing information. Request delivery of.

  The advertisement server 4 selects an advertisement that matches the attribute indicated by the attribute information received from the data reproduction terminal 3 (S15). The advertisement server 4 transmits the selected advertisement data to the data reproduction terminal 3.

  In the data reproduction terminal 3, when the advertisement acquisition unit 332 receives the advertisement data, the received advertisement data is stored in the storage unit 32 (S16), and the data reproduction unit 333 starts reproducing the main program data ( S17). The data reproduction unit 333 starts reproduction of the received advertisement data (S19) when the advertisement start timing comes (S18).

  FIG. 6 is another example of a sequence diagram showing a flow of processing in the data reproduction system S1. The sequence shown in FIG. 6 is different from the sequence shown in FIG. 5 in that the data reproduction unit 333 starts reproducing the program data before the advertisement acquisition unit 332 acquires the second advertisement from the advertisement server 4.

  Specifically, when the data acquisition unit 331 acquires distribution data in step S14, the data reproduction unit 333 starts reproduction of program data included in the distribution data (S21). Then, when the advertisement start timing approaches (YES in S22), the advertisement acquisition unit 332 transmits attribute information to the advertisement server 4 to request distribution of advertisement data. When the data acquisition unit 331 receives the advertisement data from the advertisement server 4, the data acquisition unit 331 stores the received advertisement data in the storage unit 32 (S16), and the data reproduction unit 333 receives the advertisement start timing (S18). The reproduction of the advertisement data is started (S19).

(Modification 1)
In the above description, the example in which the start timing information indicating the start timing of the period in which the first advertisement is inserted is added to the program file as meta information, but the mode of the start timing information is arbitrary. For example, the data reproduction terminal 3 can specify the start timing of the period in which the first advertisement is inserted by adding a predetermined signal having a frequency (for example, 15 KHz or higher) higher than the audible range to the audio signal of the main part. You may do it.

(Modification 2)
In the above description, the example in which the data reproduction terminal 3 acquires the advertisement data from the advertisement server 4 has been described. However, the method by which the data reproduction terminal 3 acquires the advertisement data is arbitrary. For example, the data reproduction terminal 3 may store the advertisement data in advance in the storage unit 32, acquire the distribution data from the data distribution device 2, and then read and reproduce the advertisement data stored in the storage unit 32.

[Effects of the data reproduction system S1 of the first embodiment]
As described above, in the data reproduction system S1 of the present embodiment, the data distribution device 2 stores program data and start timing information indicating the start timing of the period during which the first advertisement was inserted in the broadcast program. Delivered to the playback terminal 3. And the data reproduction terminal 3 acquires the data of the 2nd advertisement different from the 1st advertisement inserted in the broadcast program from the advertisement server 4. The data reproduction terminal 3 stops reproduction of the program data and starts reproduction of the second advertisement at the reproduction start timing of the advertisement during reproduction of the program data. In this way, the data reproduction terminal 3 can reproduce the main part of the broadcast program and allow the user of the data reproduction terminal 3 to view the second advertisement that is more suitable than the first advertisement.

  Furthermore, the data reproduction terminal 3 acquires data of the second advertisement suitable for the user attribute from the advertisement server 4. Broadcast programs are supposed to be broadcast to an unspecified number of people in the first place, so it is difficult to insert advertisements suitable for viewers. Conventionally, even if a broadcast program is distributed via the Internet N, it has been difficult to replace an advertisement inserted in the broadcast program with another advertisement. On the other hand, according to the present embodiment, the advertisement inserted in the broadcast program can be replaced with the second advertisement suitable for the user. As a result, since the user can listen to the second advertisement having a high appealing power to the user, the effect of the advertisement can be enhanced.

<Second Embodiment>

  When receiving the viewing request from the data reproduction terminal 3, the advertisement distribution device 5 transmits an advertisement request including attribute information to the advertisement server 4. The advertisement server 4 selects an advertisement corresponding to the received attribute information (S34), and transmits data of the selected advertisement to the advertisement distribution device 5. The advertisement distribution device 5 inserts the received advertisement data into the advertisement period (S35), and transmits the combined data in which the advertisement data and the program data are multiplexed to the data reproduction terminal 3 (S36). The data reproduction terminal 3 reproduces the received composite data (S37). In this manner, the user of the data reproduction terminal 3 can view a program in which an advertisement (second advertisement) different from the advertisement inserted when the program is broadcast (first advertisement) is inserted.

(Modification)
In the above description, the advertisement server 4 and the advertisement distribution device 5 are different devices, but the advertisement server 4 and the advertisement distribution device 5 may be an integrated device. For example, the advertisement distribution device 5 stores a large number of advertisements that can be distributed to the data reproduction terminal 3, and does not send an advertisement request to the advertisement server 4. May be selected.

[Effects of data reproduction system S2]
As described above, in the data reproduction system S2, the advertisement distribution device 5 inserts the second advertisement different from the first advertisement inserted when the program was broadcast into the advertisement period, and the data reproduction terminal 3 Deliver to.
