  (11) The user terminal transmits a final confirmation message (ACK) to the P / I-CSCF 131, and the P / I-CSCF 131 further transfers it to the S / I-CSCF 132.

  (12) The S / I-CSCF 132 transmits an acknowledgment message (ACK) to the streaming server 151. When the streaming server 151 confirms the ACK message, the SIP session establishment between the user terminal and the streaming server 151 is completed.

  FIG. 5 shows the processing until the bandwidth is secured in the edge router 120 for QoS control and the media stream of the moving image content is distributed from the streaming server 151 to the user terminal. The operation of each step in the sequence of FIG. 5 is described below.

  (1) When the SIP session establishment between the user terminal and the streaming server 151 is completed in the sequence of FIG. 4, in order to actually receive the media stream of the moving image content, the user terminal sends the SIP session parameters to the streaming server 151. An update request (UPDATE) is sent out.

  The SIP UPDATE message is transmitted to the P / I-CSCF 131 in the same manner as the INVITE message, and the P / I-CSCF 131 transfers the UPDATE message to the S / I-CSCF 132.

  (2) The S / I-CSCF 132 transfers the UPDATE message to the streaming server 151.

  (3) The streaming server 151 returns a parameter related to media necessary for streaming delivery by a parameter update response (200 OK) of the SIP session. The parameter update response (200 OK) is first transmitted to the S / I-CSCF 132, and the S / I-CSCF 132 transfers it to the P / I-CSCF 131.

  (4) The P / I-CSCF 131 sends a resource request message for Diameter to the RACF 140 based on the media parameter included in the received parameter update response (200 OK).

  (8) The P / I-CSCF 131 returns a SIP session disconnection response (200 OK) to the user terminal.

  In the data processing system of the present embodiment, the general user who uses the service as described above is managed based on the subscriber database (including information such as the person's name, telephone number, and address). When a user uses a service, authentication is performed using this database. The posted moving image content is managed by adding user identification information at the time of authentication, thereby enabling specification of a general user who posts the moving image content.

  The posted video content is distributed to other subscribers using the IMS Based IPTV service system provided by the communication carrier. The posted moving image content is provided to the general user in a manner in which the moving image content viewed by the general user can be selected in the same manner as other programs provided in the IPTV service. When a general user selects moving image content to be viewed, high-quality content distribution with QoS control is performed by the IMS Based IPTV distribution system.

  The telecommunications carrier's subscriber management database holds the availability of this service (posting authority, viewing authority, etc.), and refers to the above telecommunications carrier's subscriber database for login authentication when using the service. Then, check whether the service can be used. By granting the right to use this service only to subscribers who have paid the service usage fee, it is possible for the telecommunications carrier to provide the video posting service for a fee.

  For this reason, in the data processing system according to the present embodiment, it is possible to specify the user (identity information) who posted illegal video content or inappropriate video content. As a result, posting of such problematic video content is suppressed, and a safe and secure service can be provided.

  The reason why the above effect can be obtained is that, in the present invention, general users who use the service are managed based on a subscriber database (including information such as the name, telephone number, and address) of the telecommunications carrier. This is because the database is used for authentication when using the service.

  In addition, the data processing system of the present embodiment provides a means for delivering moving image content posted by a general user with high quality by QoS control. In the IMS Based IPTV service of a telecommunications carrier, in addition to program content created by broadcasting stations, etc., a variety of video content from general users is provided, which increases the participation rate of interactive services and at the same time increases the content lineup. Strengthening is also possible.

  The reason why the above effect is obtained is that the posted moving image content is distributed using the distribution system of the IMS Based IPTV service of a communication carrier having a QoS control mechanism as it is. The posted video content is also provided to the general user in a manner that allows the general user to select the video content to be viewed in the same manner as other programs provided in the IPTV service of the telecommunications carrier. .

  Furthermore, in the data processing system of the present embodiment, a communication carrier can have means for providing a charge for the moving image posting / viewing service (providing a paid service).

  The reason why the above effect can be obtained is that the service provider's subscriber management database retains whether or not the service can be used (posting authority, viewing authority, etc. are given only to the subscriber who has paid the service usage fee) This is because, in the login authentication when the user uses the service, the above-mentioned database is referred to and the availability of the service is checked.

  Since telecommunications carriers originally have a mechanism to charge subscribers and collect charges, they can be realized simply by adding information about this service to the subscriber management database, and are compatible as services provided by telecommunications carriers. Good sex.

  The present invention is not limited to the present embodiment, and various modifications are allowed without departing from the scope of the present invention. For example, in the above-described form, the distribution of the moving image content posted by the general user is a method of distributing the moving image content selected by the general user to view individually based on a request from the general user (so-called Video-on-Demand method). Although described, the distribution form of the moving image content is not limited to this.

  For example, it is possible to prepare a program such as a “program” that continuously distributes user content of a certain genre, and a general user who views it makes a viewing request for this “program” to view the video content. .

  In this embodiment, the media stream of moving image content is distributed by multicast, and a plurality of general users who view can simultaneously receive the media stream of the same moving image content.

  Furthermore, in the present embodiment, it has been exemplified that each unit of the data processing apparatus is logically realized as various functions by a computer program. However, each of these units can be formed as unique hardware, or can be realized as a combination of software and hardware.

  Needless to say, the above-described embodiment and a plurality of modifications can be combined within a range in which the contents do not conflict with each other. Further, in the above-described embodiments and modifications, the structure of each part has been specifically described, but the structure and the like can be changed in various ways within a range that satisfies the present invention.
