The

[1.2 Video overview of communication system]
Here, an outline of operation of the communication system S of the present embodiment will be described.

  First, the terminal TA1 accesses the Web server unit SR1, and transmits a request for issuing a box ID that can identify a new virtual box to the Web server unit SR1. The Web server unit SR1 issues a first session ID that can identify a session between the terminal TA1 and the information providing server SR in response to an access from the terminal TA1. The first session ID is an example of first communication session information. The box ID is an example of first identification information for associating the terminal TA1 and the terminal TB1, for example.

  When the Web server unit SR1 receives a box ID issuance request from the terminal TA1, it issues a box ID that can identify a new virtual box. The session management unit SR2 associates the issued first session ID with the issued box ID in response to the box ID issuance request received by the Web server unit SR1, and stores the first session information. Is stored in the storage means. Then, using the first session ID associated with the issued box ID, Web server unit SR1 transmits this box ID and access information for accessing Web server unit SR1 to terminal TA1. To do. This access information includes, for example, the domain name or IP address of the information providing server SR. In addition, the Web server unit SR1 transmits the issued first session ID to the terminal TA1. The terminal TA1 stores the first session ID transmitted from the web server unit SR1. Further, the Web server unit SR1 sends the issued box ID and access information for accessing the Web server unit SR1 to, for example, the mail address of the user 2 of the terminal TA2 and the mail address of the user 3 of the terminal TA3. Email to.

  Next, for example, the terminal TB1 acquires the box ID and access information transmitted to the terminal TA1 from the terminal TA1. For example, the terminal TB1 acquires the box ID and access information displayed on the display of the terminal TA1. The terminal TB1 accesses the Web server unit SR1 based on the acquired access information. And terminal TB1 transmits acquired box ID to Web server part SR1.

  The Web server unit SR1 issues a second session ID that can identify a session between the terminal TB1 and the information providing server SR in response to an access from the terminal TB1. The second session ID is an example of second communication session information. In response to access from terminal TB1, session management unit SR2 associates the box ID received from terminal TB1 with the issued second session ID and stores them in the storage means as second session information. Thus, the first session ID and the second session ID are associated with each other via the box ID. Thereby, the terminal TA1 and the terminal TB1 are appropriately associated. In addition, the Web server unit SR1 transmits the issued second session ID to the terminal TB1. The terminal TB1 stores the second session ID transmitted from the Web server unit SR1.

  Further, for example, the terminal TA2 acquires the electronic mail transmitted by the Web server unit SR1 via the mail server. The terminal TA2 accesses the Web server unit SR1 based on the access information acquired from the e-mail. And terminal TA2 transmits acquired box ID to Web server part SR1. The Web server unit SR1 issues a third session ID that can identify a session between the terminal TA2 and the information providing server SR in response to an access from the terminal TA2. The third session ID is an example of third communication session information that is different from the first communication session information. In response to access from terminal TA2, session management unit SR2 associates the box ID received from terminal TA2 with the issued third session ID and stores them in the storage means as third session information. That is, the session management unit SR2 stores the box ID and the first session ID in association with each other, and then associates the box ID with the third session ID in response to reception of the box ID from the terminal TA2. And store it in the storage means. In addition, the Web server unit SR1 transmits the issued third session ID to the terminal TA2. The terminal TA2 stores the third session ID transmitted from the Web server unit SR1.

  The terminal TB2 acquires the box ID and access information acquired by the terminal TA2 from the terminal TA2. For example, the terminal TB2 acquires by reading the box ID and access information displayed on the display of the terminal TA2. The terminal TB2 accesses the Web server unit SR1 based on the acquired access information. The subsequent operation is the same as that in the case of the terminal TB1. Further, the operation in the case of the terminal TA3 and the terminal TB3 is the same as the operation in the case of the terminal TA2 and the terminal TB2. As a result, the session management unit SR2 stores the second session IDs of the terminals TB1 to TB3 in the storage unit in association with the same box ID.

  Next, for example, the terminal TB1 transmits a reproduction request for music data selected from, for example, a music list to the Web server unit SR1. The music data reproduction request is, for example, a request indicating a music data reproduction reservation. This reproduction request includes the second session ID and the song ID of the selected song data. The web server unit SR1 receives a reproduction request for the selected music data from the terminal TB1 using the second session ID. Then, the Web server unit SR1 transmits the second session ID to the session management unit SR2. The session management unit SR2 refers to the session information stored in the storage unit and specifies the box ID associated with the second session ID acquired from the Web server unit SR1. Here, the second session ID is a session ID used when the reproduction request is received.

  Then, the session management unit SR2 transmits the specified box ID to the Web server unit SR1. The Web server unit SR1 transmits the box ID acquired from the session management unit SR2 to the database management unit SR3. The database management unit SR3 associates the box ID acquired from the Web server unit SR1, the song ID of the song data requested to be played back, and the playback order of the song data indicated by the song ID in the storage unit as song selection information. Remember. That is, the box ID, the music ID, and the reproduction order are stored in association with each other in response to the reproduction request received by the Web server unit SR1. Thereby, for example, a reproduction reservation of music data is performed. The operation when the terminal TB2 or the terminal TB3 makes a reproduction request for music data is the same as the operation when the terminal TB1 makes a reproduction request.

  Next, for example, the terminal TA1 transmits a music data transmission request to the Web server unit SR1. This transmission request includes the first session ID. Web server SR1 receives a music data transmission request from terminal TA1 using the first session ID. Then, the Web server unit SR1 transmits the first session ID to the session management unit SR2. The session management unit SR2 specifies the box ID associated with the first session ID acquired from the Web server unit SR1 with reference to the session information stored in the storage unit. Here, the first session ID is a session ID used when the transmission request is received. The box ID specified here is the same as the box ID associated with the session ID used when the reproduction request is received.

  Then, the session management unit SR2 transmits the specified box ID to the Web server unit SR1. The Web server unit SR1 transmits the box ID acquired from the session management unit SR2 to the database management unit SR3. The database management unit SR3 acquires music selection information including the box ID acquired from the Web server unit SR1 from the storage unit. Then, the database management unit SR3 transmits the acquired music selection information to the Web server unit SR1. Web server part SR1 specifies music ID from the music selection information acquired from database management part SR3. That is, the music ID associated with the box ID acquired from the session management unit SR2 is specified. A plurality of music IDs may be associated with the box ID. In this case, the Web server unit SR1 specifies one or more music IDs from among a plurality of music IDs based on, for example, the reproduction order associated with the music ID.

  The Web server unit SR1 causes the terminal TA1 to acquire the song data indicated by the specified song ID using at least the session ID associated with the box ID acquired from the session management unit SR2. The Web server unit SR1 may be configured to cause each of the terminals TA1 to TA3 to acquire the music data indicated by the specified music ID using the session ID associated with the box ID. This music data is music data requested to be reproduced from the terminal TB1. For example, the Web server unit SR1 transmits a URL (Uniform Resource Locator) indicating the location of the music data indicated by the specified music ID to, for example, the terminal TA1. In addition, this URL includes the specified music ID and access information for accessing the storage unit SR4. The Web server unit SR1 may transmit music information including the music name and artist name of the music data together with the URL indicating the location of the music data. Thus, for example, the terminal TA1 accesses the storage unit SR4 based on the URL transmitted from the Web server unit SR1.

  Then, the terminal TA1 transmits a music data transmission request to the storage unit SR4. The storage unit SR4 transmits the music data requested to be transmitted to the terminal TA1. Thereby, the terminal TA1 reproduces the music data acquired from the storage unit SR4. As another example of causing the terminal TA1 to acquire music data, the Web server unit SR1 may acquire music data indicated by the acquired music ID from the storage unit SR4. In this case, the Web server unit SR1 transmits the music data acquired from the storage unit SR4 to the terminal TA1 that is the transmission request source. Thereby, the terminal TA1 reproduces the music data acquired from the Web server unit SR1.

  Each of the terminals TA2 and TA3 can transmit a music data transmission request to the Web server SR1, similarly to the terminal TA1. In this case, the same operation as that of the terminal TA1 is performed. As a result, the terminal TA2 and the terminal TA3 acquire the music data requested to be transmitted by each. Or you may comprise so that only terminal TA1 can transmit the transmission request | requirement of music data to Web server part SR1. The terminals TA2 and TA3 acquire the music data requested by the terminal TA1.

  Further, the Web server unit SR1 uses the first session ID associated with the box ID specified as described above, for example, in response to reception of a music data playback request from the terminal TB1. The requested music data may be acquired by the terminal TA1. In this case, the music data requested to be played back from the terminal TB1 is transmitted to the terminal TA1 without waiting for a music data transmission request from the terminal TA1.

The storage unit 32 stores music data, effect data, session information, music selection information, and the like. When the Web server unit SR1, the session management unit SR2, the database management unit SR3, and the storage unit SR4 are configured by different computers, the Web server unit SR1, the session management unit SR2, the database management unit SR3, and the storage unit Each of SR4 may be configured as shown in FIG.

[3. Operation of communication system S]
Next, an operation example of the communication system S will be described. The operation example described below is an example of an outline of the operation of the communication system S described above. In the following example, the case where the Web server unit SR1, the session management unit SR2, the database management unit SR3, and the storage unit SR4 are configured by different computers will be described as an example. Therefore, the following processing is executed by the control unit 31 provided in each of the Web server unit SR1, the session management unit SR2, the database management unit SR3, and the storage unit SR4. Note that the Web server unit SR1, the session management unit SR2, the database management unit SR3, and the storage unit SR4 may be executed by one computer or may be executed by a plurality of computers. In this case, the following processing is executed by the control unit 31 provided in one or a plurality of computers in which the functions of the Web server unit SR1, session management unit SR2, database management unit SR3, and storage unit SR4 are executed.

(3-1. Association operation between terminal TA and terminal TB)
First, with reference to FIG. 3, the association operation between the terminal TA and the terminal TB will be described. FIG. 3 is a sequence diagram showing an associating operation between the terminal TA and the terminal TB.

  For example, the control unit 11 of the terminal TA1 displays a new box creation page acquired from the Web server unit SR1 on the display using a player browser. The new box creation page is a Web page for making a request for issuing a new box ID. On the new box creation page, a box ID issue request button is provided. Access information for accessing the Web server unit SR1 is set in the issue request button. When the control unit 11 of the terminal TA1 accepts designation of the issue request button by the user 1 while the new box creation page is displayed on the display, the terminal TA1 accesses the Web server unit SR1. And the control part 11 of terminal TA1 transmits the message which shows the issuing request | requirement of box ID to Web server part SR1 using a player browser (step S1). The message indicating the box ID issuance request includes, for example, the function attribute of the player browser of the terminal TA1. Here, the function attribute means an attribute of a function possessed by the control unit of the terminal. The function attribute is described in the player browser program, for example. In the present embodiment, the function attributes include “player” and “remote control”. Furthermore, “player” is classified into “master player” and “sub player”. “Master player” indicates the functional attribute of the player browser that has issued the box ID issue request. “Sub player” indicates a function attribute of a player browser that does not make a box ID issue request and is associated with the same box ID as the master player player browser. Note that the user 1 may desire a plurality of virtual boxes. In this case, the user 1 may specify the issue request button a plurality of times at different timings from the new box creation page. Thereby, a plurality of different box IDs can be used by the same user.

  When the Web server unit SR1 receives a message indicating a box ID issue request, it issues a session ID of the terminal TA1 (step S2). The session ID of the terminal TA1 is an example of a first session ID. Further, the session ID of the terminal TA1 is an ID that does not overlap with the issued session ID. When the session ID of the terminal TA1 is issued, for example, the connection established between the terminal TA1 and the Web server unit SR1 is maintained by WebSocket. That is, the terminal TA1 and the Web server unit SR1 each create a socket associated with a session ID in a predetermined area of the memory. The socket is a function indicating a network API (Application Programming Interface), for example. Then, the terminal TA1 and the Web server unit SR1 respectively set the connection destination IP address and port number in the created socket. This socket is held until there is an explicit disconnect indication. Accordingly, the terminal TA1 and the Web server unit SR1 can perform bidirectional communication until the connection is disconnected using the session ID of the terminal TA1.

  Next, the Web server unit SR1 issues a new box ID (step S3). The box ID issued here is an ID that does not overlap with the issued box ID. The Web server SR1 issues a different box ID each time a message indicating an issue request is received from the terminal TA1. Thereby, the user 1 can use a plurality of different virtual boxes.

  Next, the Web server unit SR1 generates a two-dimensional code having URL information (Step S4). This URL includes the box ID issued in step S3 and access information for accessing the Web server unit SR1. An example of the two-dimensional code is a QR code (registered trademark).

  Next, the Web server unit SR1 associates the issued box ID, the session ID of the terminal TA1, and the function attribute of the player browser of the terminal TA1 to generate session information of the terminal TA1 (Step S5). The function attribute of the player browser of the terminal TA1 is “master player”.

  Next, the Web server unit SR1 transmits the session information of the terminal TA1 to the session management unit SR2 (Step S6). Next, the session management unit SR2 stores the session information transmitted from the Web server unit SR1 in, for example, the storage unit 32 (Step S7). That is, in response to receiving a message indicating a box ID issue request, the issued box ID, the session ID of the terminal TA1, and the function attributes are associated with each other and stored as session information of the terminal TA1, for example. Stored in the unit 32. Next, when session information of terminal TA1 is stored, session management unit SR2 transmits a message indicating storage completion (OK) to Web server unit SR1 (step S8).

  Next, the Web server unit SR1 transmits the issued box ID, the session ID of the terminal TA1, and the two-dimensional code having URL information to the terminal TA1 that issued the request using the session ID of the terminal TA1. (Step S9). Next, the Web server unit SR1 transmits a two-dimensional code having URL information to the mail address of the user 2 of the terminal TA2 and the mail address of the user 3 of the terminal TA3 by e-mail (step S10). In addition, what is necessary is just to comprise so that the mail address of the user 2 and the mail address of the user 3 may be set on the web page displayed by the player browser of terminal TA1. In this case, the control unit 11 of the terminal TA1 transmits a mail address set on the Web page to the Web server unit SR1 using the player browser. The Web server unit SR1 stores the received mail address in association with the session ID of the terminal TA1. Thereby, the Web server unit SR1 can transmit a two-dimensional code having URL information to the mail address associated with the session ID of the terminal TA1 by electronic mail.

  The control unit 11 of the terminal TA1 stores the session ID and box ID received from the Web server unit SR1 in, for example, a predetermined area of the RAM using a player browser. Next, the control unit 11 of the terminal TA1 displays the two-dimensional code received from the Web server unit SR1 on the display using the player browser (Step S11). Here, the user of the terminal TA1 may perform a login operation. The login operation is an operation in which the user inputs information to the terminal TA1. In this case, the control unit 11 of the terminal TA1 transmits a message indicating a login request to the Web server unit SR1 via the network NW using the player browser (step S12). The message indicating the login request includes, for example, the session ID, user ID, and user name of the terminal TA1. Note that the user ID or the user name is information input to the terminal TA1 by a login operation.

  When the Web server unit SR1 receives a message indicating a login request from the terminal TA1, the Web server unit SR1 performs a login process (step S13). In the login process, the Web server unit SR1 determines whether, for example, the user ID and the user name included in the message indicating the login request are registered in the database of the database management unit SR. When the user ID and the user name are registered in the database, the Web server unit SR1 determines that the login is successful. In this case, the Web server unit SR1 transmits the user ID and user name included in the message indicating the login request and the session ID and box ID of the terminal TA1 to the session management unit SR2 (step S14). Next, the session management unit SR2 registers the user ID and the user name included in the message indicating the login request in the session information of the terminal TA1 in association with the session ID and box ID of the terminal TA1 (Step S15). Next, the session management unit SR2 transmits a message indicating registration completion (OK) to the Web server unit SR1 (step S16). Next, the Web server unit SR1 transmits a message indicating registration completion (OK) to the terminal TA1 (step S17).

  On the other hand, the control unit 21 of the terminal TB1 reads the URL from the two-dimensional code displayed on the display of the terminal TA1, for example, by the camera 26 using the remote control browser (step S18). Next, the control unit 21 of the terminal TB1 acquires a box ID and access information from the read URL using the remote control browser (step S19). Next, the control unit 21 of the terminal TB1 accesses the Web server unit SR1 based on the acquired access information using a remote control browser. And the control part 21 of terminal TB1 transmits acquired box ID and a function attribute to Web server part SR1 using a remote control browser (step S20). This function attribute is described in the program of the remote control browser, for example. The function attribute of the remote control browser of the terminal TB1 is “remote control”.

  When receiving the box ID and the function attribute from the terminal TB1, the Web server unit SR1 issues a session ID of the terminal TB1 (Step S21). The session ID of the terminal TB1 is an example of a second session ID. The session ID of the terminal TB1 is an ID that does not overlap with the issued session ID. When the session ID of the terminal TB1 is issued, for example, the connection established between the terminal TB1 and the Web server unit SR1 is maintained by WebSocket. Accordingly, the terminal TB1 and the Web server unit SR1 can perform bidirectional communication until the connection is disconnected using the session ID of the terminal TB1.

  Next, the Web server unit SR1 associates the received box ID, the session ID of the terminal TB1, and the function attribute of the remote control browser of the terminal TB1 to generate session information of the terminal TB1 (step S22). Next, the Web server unit SR1 transmits the session information of the terminal TB1 to the session management unit SR2 (Step S23). Next, the session management unit SR2 stores the session information of the terminal TB1 from the Web server unit SR1 in the storage unit 32 (Step S24). That is, according to the access from the terminal TB1, the box ID, the session ID of the terminal TB1, and the function attribute are associated with each other and stored in the storage unit 32 as session information of the terminal TB1. Next, after storing the session information of the terminal TB1, the session management unit SR2 transmits a message indicating storage completion (OK) to the Web server unit SR1 (step S25). Next, the Web server unit SR1 transmits a message indicating storage completion (OK) to the terminal TB1 (step S26). The message indicating the storage completion (OK) includes the issued session ID of the terminal TB1 and the box ID associated with the session ID of the terminal TB1.

  The control unit 21 of the terminal TB1 stores the session ID and box ID received from the Web server unit SR1 using the remote control browser. Note that the control unit 21 of the terminal TB1 can make a login request to the Web server unit SR1 similarly to the terminal TA1 using the remote control browser. In this case, as in the case of the terminal TA1, the Web server SR1 performs a login process in response to a login request from the terminal TB1. When the login is successful, the session management unit SR2 registers the user ID and the user name included in the message indicating the login request in the session information of the terminal TB1 in association with the session ID and the box ID of the terminal TB1.

  On the other hand, for example, the control unit 11 of the terminal TA2 receives the electronic mail transmitted by the Web server unit SR1 via the mail server. And the control part 11 of terminal TA2 displays the two-dimensional code described or attached to the electronic mail on a display using a player browser (step S27). Thereby, the control part 21 of terminal TB2 can read URL from the displayed two-dimensional code using a remote control browser. The control unit 11 of the terminal TA2 reads the URL from the two-dimensional code described or attached to the e-mail using the player browser (step S28). Next, the control unit 11 of the terminal TA2 acquires a box ID and access information from the read URL using the player browser (step S29). Next, the control unit 11 of the terminal TA2 uses the player browser to access the Web server unit SR1 based on the acquired access information. Then, the control unit 11 of the terminal TA2 transmits the acquired box ID and function attribute to the Web server unit SR1 using the player browser (step S30). The function attribute of the player browser of the terminal TA2 is “sub player”.

  When receiving the box ID from the terminal TA2, the Web server SR1 issues a session ID of the terminal TA2 (Step S31). The session ID of the terminal TA2 is an example of a third session ID. Further, the session ID of the terminal TA2 is an ID that does not overlap with the issued session ID. When the session ID of the terminal TA2 is issued, for example, the connection established between the terminal TA2 and the Web server unit SR1 is maintained by WebSocket. Accordingly, the terminal TA2 and the Web server unit SR1 can perform two-way communication using the session ID of the terminal TA2 until the connection is disconnected. Next, the Web server unit SR1 generates session information of the terminal TA2 by associating the received box ID, the session ID of the terminal TA2, and the function attribute of the player browser of the terminal TA2 (Step S32).

  Next, the Web server unit SR1 transmits the session information of the terminal TA2 to the session management unit SR2 (Step S33). Next, the session management unit SR2 stores the session information of the terminal TA2 from the Web server unit SR1 in the storage unit 32 (Step S34). That is, in response to an access from the terminal TA2, the received box ID, the session ID of the terminal TA2, and the function attribute are associated with each other and stored in the storage unit 32 as session information of the terminal TA2. Next, when the session information of the terminal TA2 is stored, the session management unit SR2 transmits a message indicating storage completion (OK) to the Web server unit SR1 (step S35). Next, the Web server unit SR1 transmits a message indicating the completion of storage (OK) to the terminal TA2 (Step S36). The message indicating the completion of storage (OK) includes the session ID of the terminal TA2 and the box ID associated with the session ID of the terminal TA2.

  The control unit 11 of the terminal TA2 stores the session ID and box ID received from the Web server unit SR1 using the player browser. Note that the control unit 11 of the terminal TA2 can make a login request to the Web server unit SR1 similarly to the terminal TA1 using the player browser. In this case, as in the case of the terminal TA1, the Web server unit SR1 performs a login process in response to a login request from the terminal TA2. When the login is successful, the session management unit SR2 registers the user ID and the user name included in the message indicating the login request in the session information of the terminal TA2 in association with the session ID and the box ID of the terminal TA2.

  On the other hand, the control unit 21 of the terminal TB2 reads the URL by, for example, the camera 26 from the two-dimensional code displayed on the display of the terminal TA2 using the remote control browser. The subsequent operation is the same as that of the terminal TB1. Further, the operation in the case of the terminal TA3 and the terminal TB3 is the same as the operation in the case of the terminal TA2 and the terminal TB2.

  FIG. 4A is a diagram illustrating an example of session information generated by the association operation between the terminal TA and the terminal TB. In the example of FIG. 4A, login is performed for the terminal TA1 and the terminal TB1, and the terminal TA2 and the terminal TB2. Therefore, as shown in FIG. 4A, the user ID and the user name are described in the session information corresponding to each of the terminals TA1 and TB1 and the terminals TA2 and TB2. On the other hand, the terminal TA3 and the terminal TB3 are not logged in. Therefore, “null” and “GUEST” are described in the session information corresponding to each of the terminal TA3 and the terminal TB3 as shown in FIG.

(3-2. Music Data Reservation Operation)
Next, the music data reservation operation will be described with reference to FIG. FIG. 5 is a sequence diagram showing a music data reservation operation. The music data reservation operation is performed in each of the terminals TB1 to TB3.

  For example, the control unit 21 of the terminal TB1 uses the remote control browser to generate a Web page for performing an operation instruction for music data in response to an instruction from the user 1, from the Web server unit SR1 using the session ID of the terminal TB1. Obtain and display. Next, the control unit 21 of the terminal TB1 displays a music list on the acquired web page using a remote control browser. The user 1 performs an operation instruction for selecting desired music data by designating a music name, for example, from the displayed music list. This operation instruction is an operation instruction for a music data reproduction request. Thereby, when receiving the operation instruction, the control unit 21 of the terminal TB1 uses the remote control browser to send a message indicating a music data reproduction request corresponding to the operation instruction using the session ID of the terminal TB1 to the Web server unit. It transmits to SR1 (step S41). The message indicating the reproduction request includes the session ID of the terminal TB1 and the music ID of the selected music data.

  When receiving the message indicating the music data reproduction request, the Web server SR1 transmits the session ID of the terminal TB1 included in the message indicating the reproduction request to the session management unit SR2 (step S42). Next, the session management unit SR2 specifies, for example, the box ID associated with the session ID of the terminal TB1 with reference to the session information stored in the storage unit 32 (step S43). At this time, the session management unit SR2 specifies a session ID associated with the specified box ID and each of the terminals TA1 to TA3. Next, the session management unit SR2 transmits the specified box ID and session ID to the Web server unit SR1 (step S44). Next, the Web server unit SR1 transmits the box ID acquired from the session management unit SR2 to the database management unit SR3 (step S45). Thereby, database management part SR3 acquires box ID matched with session ID of terminal TB1.

  Next, the database management unit SR3 associates the box ID acquired from the Web server unit SR1, the session ID of the terminal TB1, the song ID of the song data requested to be played back, and the playback order of the song data, and selects the music selection information. Is registered in the database in the storage unit 32 (step S46). That is, when the message indicating the reproduction request is received by the Web server SR1, the box ID, the session ID of the terminal TB1, the music ID, the reproduction order, and the like are associated and stored. Note that each time a message indicating a playback request is received, the music selection information of the music data requested to be played and the playback order of the music data are added to the music selection information, for example, in the music selection information. Thus, the one or more music IDs and the reproduction order of the music data indicated by the one or more music IDs are registered in the database in association with the box ID. Accordingly, the Web server unit SR1 can cause the terminal TA to acquire music data indicated by any one or a plurality of music IDs registered in the database based on the reproduction order registered in the database. Therefore, a plurality of pieces of music data requested to be played can be quickly played back on the terminal TA based on the respective playback orders.

  Next, the database management unit SR3 transmits a message indicating registration completion (OK) to the Web server unit SR1 (step S47). Note that the processing in steps S41 to S47 is performed in the same manner when a message indicating a music data reproduction request is transmitted from the terminal TB2 or the terminal TB3. Here, the reproduction order of the music data is, for example, the order in which the message indicating the music data reproduction request is received. FIG. 4B is a diagram showing an example of music selection information registered in the database by the database management unit SR3.

  Next, the Web server unit SR1 transmits the music selection information acquired from the database management unit SR3 to the terminals TA1 to TA3 using the session IDs of the terminals TA1 to TA3 (step S48). The music selection information may include a music title, an artist name, and the like. Each control unit 11 of the terminals TA1 to TA3 receives the music selection information from the Web server unit SR1 using the player browser, and displays the received music selection information on the display (step S49). In addition, each control part 11 of terminal TA1-terminal TA3 is comprised so that it may determine whether the box ID contained in music selection information corresponds with the stored box ID using a player browser. Also good. In this case, the control unit 11 displays the received music selection information on the display only when it is determined that the box IDs match using the player browser.

(3-3. Music data playback operation)
Next, the music data playback operation will be described with reference to FIG. FIG. 6 is a sequence diagram showing the music data playback operation. Note that the music data reproduction operation is performed in each of the terminals TA1 to TA3. For this reason, in the example of FIG. 6, the processing of the terminals TA2 and TA3 is not shown.

  For example, when receiving the music selection information from the web server unit SR1 using the player browser, the control unit 11 of the terminal TA1 determines whether or not the music data is being reproduced (step S51). If the control unit 11 of the terminal TA1 determines that the music data is being reproduced using the player browser (step S51: YES), the reproduction process is continued. On the other hand, if the control unit 11 of the terminal TA1 determines that the music data is not being reproduced using the player browser (step S51: NO), the process proceeds to step S52.

  In step S52, the control unit 11 of the terminal TA1 uses a player browser to determine whether or not this player browser is a master player. That is, when the player browser of the terminal TA1 is a player browser that has issued a box ID issue request, it is determined that the player browser is a master player. When it is determined that the player is not the master player (step S52: NO), the control unit 11 of the terminal TA1 sets the player browser in a standby state. On the other hand, if the control unit 11 of the terminal TA1 determines that the player is a master player using the player browser (step S52: YES), the process proceeds to step S53.

  In step S53, the control unit 11 of the terminal TA1 transmits a message indicating a music data transmission request to the Web server unit SR1 using the session ID of the terminal TA1 using the player browser. The message indicating the transmission request includes the session ID of the terminal TA1. Only the master player can make a music data transmission request through the processing of step S52.

  In addition, you may comprise so that determination whether it is a master player in step S52 may not be performed. In this case, when the control unit 11 of the terminal TA1 determines that the music data is not being reproduced using the player browser (step S51: NO), the process proceeds to step S53. That is, in this case, all player browsers of the terminals TA1 to TA3 have the same function.

  When receiving the message indicating the music data transmission request, the Web server unit SR1 transmits the session ID of the terminal TA1 included in the message indicating the transmission request to the session management unit SR2 (step S54). Next, the session management unit SR2 specifies the box ID associated with the session ID of the terminal TA1 with reference to, for example, the session information stored in the storage unit 32 (Step S55). At this time, the session management unit SR2 specifies the session ID of each of the terminals TA2 and TA3, which is a session ID associated with the specified box ID.

  Next, the session management unit SR2 transmits the specified box ID and session ID to the Web server unit SR1 (step S56). Next, the Web server unit SR1 transmits the box ID acquired from the session management unit SR2 to the database management unit SR3 (step S57). Thereby, database management part SR3 acquires box ID matched with session ID of terminal TA1. Next, the database management unit SR3 acquires music selection information including the box ID acquired from the Web server unit SR1 from the database in the storage unit 32 (step S58). Next, the database management unit SR3 transmits the acquired music selection information to the Web server unit SR1 (step S59).

  Next, the Web server unit SR1 determines whether or not the song selection information acquired from the database management unit SR3 includes the song ID of the song data reserved for playback (step S60). When it is determined that the music ID of the music data reserved for reproduction is included (step S60: YES), the process proceeds to step S61. On the other hand, when it is determined that the music ID of the music data reserved for reproduction is not included (step S60: NO), the process ends.

  In step S61, the Web server SR1 specifies the music ID based on the reproduction order associated with the music ID included in the music selection information, and proceeds to step S62. Thereby, for example, one music ID of music data whose music selection order is first is specified from among a plurality of music IDs. In step S58, the database management unit SR3 may determine whether or not the music ID of the music data reserved for reproduction is included in the music selection information including the box ID. When the music ID of the music data reserved for reproduction is included, the database management unit SR3 selects a music ID from the plurality of music IDs based on the reproduction order associated with the music ID included in the music selection information. Identify. In this case, the database management unit SR3 transmits the specified music ID to the Web server unit SR1, and proceeds to step S62. In step S62, the Web server SR1 transmits the URL indicating the location of the music data indicated by the specified music ID to the terminals TA1 to TA3 using the session IDs of the terminals TA1 to TA3.

  Each control unit 11 of the terminals TA1 to TA3 uses the player browser to access the storage unit SR4 based on the URL received from the Web server unit SR1. And the control part 11 of terminal TA1-terminal TA3 each transmits the message which shows the transmission request of music data to storage part SR4 using a player browser (step S63). Thereby, the storage unit SR4 transmits the music data requested to be transmitted to the terminal TA1 to the terminal TA3 (step S64). For example, the storage unit SR4 distributes the music data requested for transmission to the terminals TA1 to TA3 by streaming. Each control unit 11 of the terminals TA1 to TA3 receives the music data distributed from the storage unit SR4 using the player browser, and stores it in the buffer memory area. When a predetermined amount of music data is accumulated in the buffer memory area, each control unit 11 of the terminals TA1 to TA3 starts playing music data using the player browser (step S65).

  Next, for example, when a predetermined time has elapsed after the reproduction of the music data is started, each control unit 11 of the terminal TA1 to the terminal TA3 transmits a message indicating a reproduction history update request to the Web server unit SR1 using the player browser. (Step S66). The predetermined time is set, for example, between 5 seconds and 10 seconds. The message indicating the playback history update request includes, for example, the song ID of the song data being played, the session ID, and the like. Thereby, Web server part SR1 updates the music selection information acquired by step S59 (step S67). For example, information indicating that the specified music ID is being reproduced is added to the music selection information. Next, the Web server unit SR1 transmits a message indicating update completion (OK) to the terminals TA1 to TA3 (step S68).

  Next, when the reproduction of the music data is completed using the player browser (step S69), each control unit 11 of the terminal TA1 to the terminal TA3 determines whether or not the player browser is a master player, as in step S52. Is determined (step S70). The control unit 11 puts a player browser that is not the master player into a standby state. On the other hand, when the player browser is the master player, the control unit 11 of the terminal TA uses the player browser to transmit a message indicating the end of reproduction of the music data to the Web server unit SR1 using the session ID of the terminal TA. (Step S71). In other words, the message indicating the end of reproduction of the music data is a message indicating a transmission request for music data next to the music data whose reproduction has ended. The message indicating the end of playback includes the session ID and the music ID of the music data that has been played back. By the process of step S70, only the master player can make a transmission request for the next music data. As a result, the sub player reproduces the next music data as the music data is reproduced by the master player. Thereby, even if the reproduction end of the music data by the master player is delayed due to the influence of the network state, the sub player can start the reproduction of the next music data in synchronization with the master player.

  In addition, you may comprise so that determination whether it is a master player in step S70 may not be performed. In this case, each control unit 11 of the terminal TA1 to the terminal TA3 uses the player browser to transmit a message indicating the end of reproduction of the music data to the Web server unit SR1 using each session ID. . As a result, the player browser with the earliest playback completion among the player browsers first makes a transmission request for the next music data to the Web server unit SR1. Therefore, the player browser that has not made a transmission request starts reproduction of the next music data in synchronization with the player browser that has made the transmission request, regardless of the reproduction state of the music data.

  When receiving a message indicating the end of reproduction of music data, the Web server unit SR1 transmits, for example, the session ID of the terminal TA1 included in the message indicating the end of reproduction to the session management unit SR2 (step S72). Note that the processing in steps S73 and S74 is the same as the processing in steps S55 and S56. The Web server SR1 transmits the song ID of the song data that has been played back and the box ID acquired from the session manager SR2 to the database manager SR3 (step S75).

  The database management unit SR3 acquires music selection information including the box ID acquired from the Web server unit SR1 from the database in the storage unit 32. Next, the database management unit SR3 updates the music selection information based on the music ID acquired from the Web server unit SR1 (step S76). That is, the database management unit SR3 deletes the music ID and the playback order of the music data that has been played back from the acquired music selection information. At this time, the music selection information other than the deleted music ID may be included in the music selection information. In this case, the reproduction order associated with the music ID other than the deleted music ID is updated. For example, the playback order associated with a music ID other than the deleted music ID is incremented by one. The updated music selection information is reflected in the database in the storage unit 32.

  Next, the database management unit SR3 transmits the updated music selection information to the Web server unit SR1 (step S77). Next, the Web server unit SR1 determines whether or not the song selection information acquired from the database management unit SR3 includes the song ID of the song data reserved for playback (step S78). If it is determined that the song ID of the song data reserved for reproduction is included (step S78: YES), the Web server SR1 proceeds to step S79. On the other hand, when it is determined that the song ID of the song data reserved for reproduction is not included (step S78: NO), the process ends.

  In step S79, the web server unit SR1 specifies the music ID based on the reproduction order associated with the music ID included in the music selection information. That is, the song ID of the song data in the next playback order of the music data that has been played back is specified. Next, the Web server SR1 transmits the URL indicating the location of the music data indicated by the specified music ID to the terminal TA1 to the terminal TA3 using the session IDs of the terminals TA1 to TA3 (step S80). Accordingly, the Web server unit SR1 can cause the terminal TA1 to the terminal TA3 to acquire the music data in the next playback order of the music data that has been played back in response to the reception of the message indicating the playback end. .

  Each control unit 11 of the terminals TA1 to TA3 uses the player browser to access the storage unit SR4 based on the URL received from the Web server unit SR1. And each control part 31 of terminal TA1-terminal TA3 transmits the message which shows the transmission request of music data to storage part SR4 using a player browser. In this way, the process after step S64 mentioned above is repeated.

(3-4. Operation instruction operation during music playback)
Next, an operation instruction operation during music reproduction will be described with reference to FIG. FIG. 7 is a sequence diagram showing an operation instruction operation during music reproduction. Note that the operation instruction operation during music reproduction is performed in each of the terminals TB1 to TB3.

  For example, the control unit 21 of the terminal TB1 uses the remote control browser to generate a Web page for performing an operation instruction for music data in response to an instruction from the user 1, from the Web server unit SR1 using the session ID of the terminal TB1. Get and display. Thereby, the user 1 can be made to perform an operation instruction on the music data from the terminal TB1. On the Web page displayed in this manner, for example, operation buttons corresponding to operation instructions such as playback stop, restart, and effect presentation are displayed. User 1 presses a desired operation button on the Web page. Accordingly, the control unit 21 of the terminal TB1 transmits a message indicating an operation instruction corresponding to the operation button pressed by the user 1 to the Web server unit SR1 using the session ID of the terminal TB1 using the remote control browser. (Step S91). This operation instruction is an operation instruction for music data that is currently reproduced by the terminal TA1. The message indicating the operation instruction includes the session ID of the terminal TB1 and the content of the operation instruction.

  When receiving the message indicating the operation instruction, the Web server unit SR1 transmits the session ID of the terminal TB1 included in the message indicating the operation instruction to the session management unit SR2 (step S92). Next, the session management unit SR2 identifies the box ID associated with the session ID of the terminal TB1 with reference to the session information stored in the storage unit 32, for example (step S93). That is, the box ID associated with the session ID of the terminal TB1 is specified in response to the reception of the message indicating the operation instruction. At this time, the session management unit SR2 specifies the session ID of the terminal TA1, which is a session ID associated with the specified box ID. For example, the session management unit SR2 specifies a session ID associated with the same user ID and user name as the session ID of the terminal TB1.

  Next, the session management unit SR2 transmits the specified box ID and session ID to the Web server unit SR1 (step S94). Next, the Web server unit SR1 transmits a message indicating the received operation instruction to the terminal TA1 using the session ID of the terminal TA1 associated with the specified box ID (Step S95). Thereby, the operation instruction performed at the terminal TB1 can be quickly transmitted to the terminal TA1. The message indicating the operation instruction includes the box ID, the session ID of the terminal TA1, and the content of the operation instruction.

  For example, when receiving a message indicating an operation instruction from the Web server unit SR1 using the player browser, the control unit 11 of the terminal TA1 determines whether or not the operation instruction is an effect presentation (step S96). When it is determined that the operation instruction is effect presentation (step S96: YES), the control unit 11 of the terminal TA1 proceeds to step S97. On the other hand, when it is determined that the operation instruction is not an effect presentation (step S96: NO), the control unit 11 of the terminal TA1 proceeds to step S102. When the control unit 11 of the terminal TA1 receives a message indicating an operation instruction using the player browser, whether or not the box ID included in the message indicating the operation instruction matches the stored box ID. May be determined. In this case, the control unit 11 of the terminal TA1 performs the processes after step S96 only when it is determined that the box IDs match using the player browser.

  In step S97, the control unit 11 of the terminal TA1 transmits a message indicating an effect data transmission request to the Web server unit SR1 using the session ID of the terminal TA1 using the player browser. The message indicating the effect data transmission request includes the session ID of the terminal TB1 and the song ID of the currently played song data.

  When receiving a message indicating the effect data transmission request, the Web server SR1 transmits this message to the storage SR4 (step S98). The storage unit SR4 transmits effect data associated with the music ID included in the message acquired from the Web server unit SR1 to the Web server unit SR1 (step S99). The Web server unit SR1 transmits the effect data acquired from the storage unit SR4 to the terminal TA1 using the session ID of the terminal TA1 (Step S100).

  When receiving the effect data from the Web server unit SR1 using the player browser, the control unit 11 of the terminal TA1 executes effect presentation processing based on the effect data (step S101). In the effect presenting process, the control unit 11 of the terminal TA1 uses the player browser to output sound such as applause and excitement sound from the speaker. The control part 11 of terminal TA1 displays a decoration image etc. on a display using a player browser.

  In step S102, the control unit 11 of the terminal TA1 uses the player browser to determine whether or not the operation instruction is a reproduction stop. When it is determined that the operation instruction is to stop reproduction (step S102: YES), the control unit 11 of the terminal TA1 proceeds to step S103. On the other hand, when it is determined that the operation instruction does not stop the reproduction (step S102: NO), the control unit 11 of the terminal TA1 proceeds to step S105.

  In step S103, the control unit 11 of the terminal TA1 stops the reproduction of the currently reproduced music data using the player browser. Next, the control unit 11 of the terminal TA1 executes a music acquisition process using the player browser (step S104). The music acquisition process is a process of acquiring music data next to music data for which playback has been stopped. In the music acquisition process, the same processes as in steps S70 to S80 described above are performed.

  In step S105, the control unit 11 of the terminal TA1 determines whether or not the operation instruction is a restart using the player browser. When it is determined that the operation instruction is restart (step S105: YES), the control unit 11 of the terminal TA1 proceeds to step S106. In step S106, the control unit 11 of the terminal TA1 uses the player browser, and the control unit 11 of the terminal TA1 restarts the reproduction of the currently reproduced music data from the beginning. On the other hand, when it is determined that the operation instruction is not a restart (step S105: NO), the control unit 11 of the terminal TA1 performs a process according to another operation instruction using the player browser.

  As described above, according to the embodiment, the information providing server SR associates the box ID with the session ID of the terminal TA in response to the reception of the box ID issue request from the terminal TA. Remember. Then, the information provision server SR transmits the issued box ID and access information for accessing the information provision server SR to the terminal TA. The information providing server SR stores the box ID and the session ID of the terminal TB in association with each other according to the access from the terminal TB that has acquired the box ID and access information transmitted to the terminal TA. And information provision server SR will specify the box ID matched with the session ID of terminal TB, if the reproduction request of music data is received from terminal TB using session ID of terminal TB. Then, the information providing server SR causes the terminal TA to acquire the music data requested to be played using the session ID of the terminal TA associated with the specified box ID. Therefore, according to the above embodiment, the terminal TA and the terminal TB are appropriately linked, and the music data requested to be played back from the terminal TB can be quickly played back on the terminal TA.
