As described above, the personal server unit 12 is formed in the user terminal device 10 in which the personal server software is executed, and a communication session such as a pipe is established between the core module 14 and the service providing server 20. Therefore, the active user management means 21 detects and manages the status of the active user in real time by detecting the user terminal device 10 in which this communication session is established. The active user management unit 21 communicates with the core module 14 to detect and manage what module 15 is present in the user terminal device 10 used by the active user.

  The module cooperation means 22 has a function of using a web service provided in each module 15 in cooperation with the module 15 of the active user and the local web server 13.

  Next, in the information processing system 100 configured as described above, a case where the service providing server 20 provides a video sharing service on a website and the module 15 includes a video encoding module 15a will be described.

  A video sharing service allows a specific or unspecified user to upload (post) video content (hereinafter sometimes simply referred to as “video”), and to specify or specify an uploaded video. It is a service on the web that the user can browse. In this embodiment, it is assumed that a moving image released by the moving image sharing service is released by streaming playback in a format such as Adobe Flash (trademark).

  The video encoding module 15a is a module for encoding a moving image locally on the user terminal device 10 and uploading the encoded moving image to the service providing server 20. The details will be described in an embodiment described later. .

  FIG. 4 is a diagram illustrating an example of a functional configuration of the service providing server 20 when providing a video sharing service. As shown in FIG. 4, the service providing server 20 includes an active user management unit 21, a module cooperation unit 22, a disclosure unit 23, and a reproduction unit 24. Among these, the active user management means 21 and the module cooperation means 22 are as described above.

  The publishing means 23 has a function for uploading the moving image received from the user terminal device 10 to the moving image sharing service and publishing it to a specific or unspecified user. In addition, the playback unit 24 has a function for playing on the user terminal device 10 a video arbitrarily selected by the user from the videos released by the release unit 23.

  For convenience of explanation, a user terminal device used by a user who uploads a video to the video sharing service is represented by 10x, and a user terminal device used by a user who browses the video uploaded to the video sharing service is represented by 10y. As a premise, personal server software is executed on the user terminal device 10x.

  First, a process in which the video encoding module 15a of the user terminal device 10x performs encoding and uploading of a moving image will be described.

  FIG. 5 is a block diagram illustrating a configuration of the video encoding module 15a according to the first embodiment. The video encoding module 15 a includes an encoding unit 81 and an uploading unit 82.

  The encoding unit 81 has a function of encoding a moving image to be uploaded to the service providing server 20 into a moving image in a streaming format locally on the user terminal device 10x before uploading. Specifically, the encoding unit 81 uses, for example, a moving image recorded in a file format such as avi, mov, mpg (mpeg), wmv, 3gp, or the like as a streaming movie in a file format such as flv used in the video sharing service. Convert to

  The upload unit 82 has a function of transmitting the video encoded by the encoding unit 81 to the service providing server 20 and uploading the video to the video sharing service.

  FIG. 6 is a flowchart illustrating a process flow when uploading a moving image from the user terminal device 10x to the service providing server 20 in the first embodiment. FIG. 7 is an example of a moving image list page displayed on the user terminal device 10 x that has accessed the service providing server 20.

  First, when uploading a video, the user instructs to upload by clicking on the link portion 85 for instructing video upload displayed in the video list page (S141). After instructing the upload execution, a moving image file to be uploaded is selected from among the files stored locally in the user terminal device 10x (S142).

  When a moving image file is selected, the encoding means 81 of the video encoding module 15a encodes the selected moving image file and converts it into a streaming-format moving image that is published on the moving image sharing service (S143).

  After performing the encoding process locally on the user terminal device 10x, the upload unit 82 transmits the encoded streaming-format video to the service providing server 20 and uploads the video to the video sharing service (S144).

  Thereafter, the moving image uploaded to the moving image sharing service is disclosed to specific or unspecified users. Then, when the user selects an arbitrary moving image and gives an instruction for reproduction, the selected moving image is reproduced on the user terminal device 10y. Specifically, for example, when a specific or unspecified user accesses the service providing server 20 via the user terminal device 10y, any user can view any video that has been uploaded to the video sharing service. Thumbnail images of moving images are displayed in a list on the browser of the user terminal device 10y. The user selects an image to be reproduced from thumbnail images displayed in a list, images searched using the moving image search function, and the like, and reproduces a moving image.

  As described above, according to the first embodiment, the service providing server 20 cooperates with the user terminal device 10x in which the personal server software is activated to share a part of the processing load related to the video release of the video sharing service with the user terminal device. It can be distributed on the 10x side. Specifically, in a conventional video sharing service, a video posted by a user is encoded in a streaming format or the like on the server 20 side. However, since this encoding is a process that requires a great load, An excessive load is generated on the providing server 20, and the operation of the server tends to become unstable. However, according to the present embodiment, in the video sharing service, the video is encoded on the user terminal device 10x side, and the service providing server 20 receives the encoded video and publishes the received video as it is. For this reason, there exists an effect that the processing load of the service provision server 20 can be reduced.

  Next, a case where the video encoding module 15a of the user terminal device 10x includes a means for distributing a moving image to another user terminal device 10y in addition to the encoding means 81 and the upload means 82 will be described.

  FIG. 8 is a block diagram illustrating a configuration of the video encoding module 15a according to the second embodiment. The video encoding module 15 a includes a moving image storage unit 83 and a moving image distribution unit 84 in addition to the encoding unit 81 and the upload unit 82.

  The moving image storage unit 83 has a function of storing a moving image having the same content as the moving image uploaded to the service providing server 20 by the upload unit 82 in a format that can be distributed to the other user terminal device 10y. The moving image file to be stored may be a moving image encoded in a streaming format or the original moving image file itself before encoding. In addition, it is preferable that the moving image storage unit 83 stores a moving image having a higher image quality and a lower compression rate than the moving image uploaded to the service providing server 20. In other words, when storing a moving image in the streaming format in the moving image storage unit 83, the encoding unit 81 performs an encoding process by increasing the resolution, the frame rate, etc. than the moving image uploaded to the service providing server 20, and obtains the result. It is preferable to store the streaming image having the high image quality and low compression rate in the moving image storage unit 83. In the following, an example in which a high-quality and low-compression streaming image is stored in the moving image storage unit 83 will be described.

  The moving image distribution unit 84 has a function of distributing the moving image stored in the moving image storage unit 83 to the user terminal device 10y of a specific or unspecified user via the local web server 13. When a moving image in streaming format is stored in the moving image storage means 83, streaming reproduction is performed, and when the moving image is stored in a moving image file format such as avi, the moving image file is transmitted to the user terminal device 10y.

  On the other hand, in the second embodiment, when the user is instructed to play a predetermined video via the user terminal device 10y, the service providing server 20 gives the user terminal device 10x that is the upload source of the predetermined video to the user. An instruction to reproduce the predetermined moving image is transmitted to the terminal device 10 y via the module cooperation unit 22.

  FIG. 9 is a flowchart illustrating a processing flow when uploading a moving image from the user terminal device 10x to the service providing server 20 in the second embodiment. Here, the flow from Step S141 to Step S144, that is, the process from encoding the video selected by the user locally on the user terminal device 10x to uploading it to the video sharing service is the same as in the first embodiment.

  In parallel with or before and after the encoding process (S143) and the upload process (S144), the video encoding module 15a stores the moving image in the moving image storage unit 83 (S145). At this time, the encoding unit 81 first encodes the moving image file with a higher image quality and lower compression rate than the encoding process in step S143, and the moving image storage unit 83 stores the obtained moving image in the streaming format with higher image quality and lower compression rate. To store. Thus, when a moving image is uploaded to the moving image sharing service according to the user's instruction, at the same time, a moving image having the same content as the uploaded moving image and having higher image quality is prepared in a form that can be distributed to the user terminal device 10x.

  On the other hand, when the service providing server 20 receives a video to be uploaded from the user terminal device 10x, the service providing server 20 stores the video and information (for example, a terminal ID) for identifying the user terminal device 10x as a transmission source in association with each other. To store. Thereafter, the moving image uploaded to the moving image sharing service is released to specific or unspecified users.

  FIG. 10 is a flowchart illustrating a flow of processing in which the user browses a moving image published by the moving image sharing service in the second embodiment. FIG. 11 is a diagram illustrating a flow of information when the uploading user terminal device 10x of the moving image to be reproduced is not active. FIG. 12 is a diagram illustrating a flow of information when the uploading user terminal device 10x of the moving image to be reproduced is active.

  A specific or unspecified user accesses the service providing server 20 via the user terminal device 10y, selects an arbitrary video that can be viewed by the user from videos uploaded to the video sharing service, Is instructed to be reproduced (S151).

  At this time, the service providing server 20 searches the storage means, identifies the user terminal device 10x that uploaded the selected video, and determines whether the user terminal device 10x is currently active by the active user management means 21. (S152).

  Then, when the user terminal device 10x that is the upload source of the moving image is not active (S152: NO), the service providing server 20 distributes the selected moving image toward the user terminal device 10y as shown in FIG. That is, when the original user terminal device 10x that uploaded the video to be played is not active (the local web server 13 is not up), the service providing server 20 selects the video selected by the user as in the first embodiment. Then, streaming delivery is performed to the user terminal device 10y (S153).

  On the other hand, when the user terminal device 10x that is the upload source of the moving image is active (S152: YES), as shown in FIG. 12, the selected moving image is distributed from the user terminal device 10x to the user terminal device 10y.

  Specifically, first, the module cooperation unit 22 of the service providing server 20 instructs the video encoding module 15a of the user terminal device 10x to stream the selected video to the user terminal device 10y ( S154). This command includes an ID for identifying the moving image selected by the user as necessary.

  When receiving the above command from the service providing server 20, the user terminal device 10x identifies a moving image to be played based on the ID included in the command, and distributes the moving image to the user terminal device 10y (S155).

  As described above, according to the second embodiment, the service providing server 20 cooperates with the user terminal device 10x in which the personal server software is activated to share part of the processing load related to the video distribution of the video sharing service with the user terminal. It can be distributed to the device 10x side. Specifically, if the original user terminal device 10x that uploaded the video to be played is active, the user terminal device 10x delivers the video, while if the user terminal device 10x is not active, the service providing server 20 Delivers videos. In this way, there is an extraordinary effect that the load of the moving image distribution process is distributed and a higher quality moving image can be reproduced.

  Next, a case where the service providing server 20 provides a social networking service (SNS) and provides a video sharing service via SNS will be described. For convenience of explanation, the service providing server 20 that provides the SNS is represented as an SNS server 25.

  The SNS server 25 includes a member information database (hereinafter referred to as “member DB”) 26. In the member DB 26, for each user, human relationship information indicating the degree of connection between the user and other users is recorded. Based on the human relationship information recorded in the member DB 26, the SNS server 25 establishes a friendship relationship such that the user A and the user B are “friends” or the user A and the user C are “friends of friends”. It can be recognized (extracted / calculated). In this embodiment, the data structure of the member DB 26 and the method for recognizing the friendship are not particularly shown, but any data structure and method for recognition can be adopted as long as the friendship between the users can be recognized. Needless to say.

  On the other hand, the user terminal device 10 includes a video encoding module 15a, and performs the same processing as that described in the first and second embodiments.

  However, in Example 3, when uploading a moving image to the SNS server 25, the user designates a sharing range of the moving image. Then, the SNS server 25 stores the uploaded moving image and the sharing range designated by the user in the storage unit in association with each other. The sharing range indicates the degree of friendship of the SNS member who wants to share a video. For example, only a “friend” shares a video, or a “friend of a friend” shares a video, It is possible to specify that “all members” are allowed to share files.

  Next, the moving image sharing process in the present embodiment will be described in detail with reference to FIGS.

  FIG. 13 is a diagram illustrating an example of a human relationship between members registered in the SNS server 25. Each node in FIG. 13 represents a user name, and a side connecting the nodes indicates that users at both end nodes of the side are in direct friendship. Therefore, in the example of FIG. 13, user A is a friend with user B, user B is a friend with users A, C, and E, and user C is a friend with users B and D. Further, the user A and the user C are in a relationship of “friends of friends”.

  FIG. 14 is a diagram illustrating an example of a moving image uploaded to the SNS server 25 by each of the users A to E illustrated in FIG. For example, the user A uploads three videos A1, A2, and A3 to the video sharing service, and the sharing range is “A1” is shared only with friends, “A2” is shared with friends of friends, and “A3” is a member It is set to share with the whole. Further, the moving images uploaded by the users B to E and the sharing ranges thereof are set as shown in FIG.

  FIG. 15 shows a list of videos that can be played back by user A when user A opens the video sharing page of SNS server 25 in the sharing range shown in FIG. 14 on the assumption of the human relationship shown in FIG. FIG. The SNS server 25 determines a moving image that the user A can reproduce based on the sharing range of the moving image uploaded by each user (user terminal device 10).

  In the example shown in FIGS. 13 to 15, since user A and user B are direct friends, the uploaded video can be used regardless of whether the sharing range is “friends”, “friends of friends” or “whole”. Can be played and viewed. On the other hand, since the user A and the user C are “friends of friends”, the user A cannot share the video “C1” that the user C can share only with “friends”. Among the videos uploaded by the user C, the user A can play a video whose sharing range is “friends of friends” or “whole”. Further, since the user A and the user D are in a relationship of “friends of friends”, the user A can reproduce only “D3” that the user D permits sharing to all members. In addition, since the user E can share only “friends”, the user A cannot view the video uploaded by the user E.

  In this way, a moving image can be shared between specific members registered in the SNS server 25. In addition, it becomes possible to designate a moving image sharing range (disclosure range) for each moving image based on friendship information between the members. This makes it easy to share a video only between specific friends.

  As described above, according to the present embodiment, by operating personal server software, a local web server and one or more modules are configured in the user terminal device, and the local web server and modules provide online services. By performing the processing in cooperation with the web server that performs this, it becomes possible to provide an online service (particularly, a video sharing service) that seamlessly cooperates with the user terminal device.

  The present invention is not limited to the above-described embodiment, and can be implemented in various other forms without departing from the gist of the present invention. For this reason, the said embodiment is only a mere illustration in all points, and is not interpreted limitedly. For example, the above-described processing steps can be executed in any order or in parallel as long as there is no contradiction in the processing contents.

  For example, in the present embodiment, personal server software is downloaded from the service providing server 20 and installed in the user terminal device 10. However, the personal server software may be downloaded from another web server. Further, it may be stored in a recording medium such as a DVD and distributed to the user.

  Furthermore, in the present embodiment, the video encoding module 15a is illustrated as an example of the module, but it goes without saying that modules for providing other online services can be arbitrarily combined.

1 is a diagram illustrating a schematic configuration of an information processing system 100. FIG. 2 is a block diagram illustrating an example of a configuration of a user terminal device 10. FIG. It is a block diagram which shows an example of a function structure of the user terminal device 10 and the service provision server 20. FIG. It is a figure which shows an example of a function structure of the service provision server 20 in the case of providing a moving image sharing service. It is a block diagram which shows the structure with which the video encoding module 15a in Example 1 is provided. In Example 1, it is a flowchart which shows the flow of a process when uploading a moving image to the service provision server 20 from the user terminal device 10x. It is an example of the moving image list page displayed on the user terminal device 10x which accessed the service provision server 20. FIG. It is a block diagram which shows the structure with which the video encoding module 15a in Example 2 is provided. In Example 2, it is a flowchart which shows the flow of a process when uploading a moving image to the service provision server 20 from the user terminal device 10x. In Example 2, it is a flowchart which shows the flow of the process in which a user browses the moving image currently disclosed by the moving image sharing service. It is a figure which shows the flow of information when the upload origin user terminal device 10x of the moving image reproduced is not active. It is a figure which shows the flow of information when the upload origin user terminal device 10x of the moving image reproduced is not active. It is a figure which shows an example of the human relationship of the member registered into the SNS server. It is a figure which shows an example of the moving image which user AE uploaded to the SNS server 25. FIG. It is a figure (an example) which shows the list of the animation which user A can reproduce.
