[0041] [2-5. Advance information provision procedure] 8 illustrates a procedure for providing advance information. The content management system 20 provides advance information according to the following procedure. [S810] The user management server 21 acquires the movie file. Specifically, based on a user's specification, a movie file managed by the video distribution system 30 is acquired from the file management server 31 and stored in the storage 25 via the file management server 24. At this time, movie management information (FIG. 7(a)) regarding the acquired movie file is generated and registered in the storage 25 via the data management server 23.

[0042] [S820] The user management server 21 extracts elements from the movie file. Specifically, a movie file stored in storage 25 is acquired via file management server 24, and frames and audio data are extracted. The audio data is converted into text by speech recognition processing. The text may be edited by the user as necessary.

[0043] [S830] The user management server 21 provides the advance information. Specifically, advance information (FIGS. 1 and 2) is generated in which one or more representative frames are laid out from the extracted frames, either in response to a user operation or automatically, and is provided to the user.

[0044] [S840] The user management server 21 registers the management information. Specifically, the extracted frames are stored in the storage 25 via the file management server 24. In addition, frame management information (FIG. 7(b)) and text management information (FIG. 7(c)) are generated and registered in the storage 25 via the data management server 23.

[0045] [2-6. Video distribution procedure] 9 illustrates a procedure for distributing moving images. The content management system 20 and the moving image distribution system 30 distribute moving images according to the following procedure. [S905] The user management server 21 receives a movie playback request from the user terminal 10 . Specifically, a playback request is sent in the following procedure from the user terminal 10. Note that the URL contains movie specification information capable of specifying a movie, and parameters capable of specifying a representative frame in the preceding information. (1) An image of the two-dimensional code contained in the preceding information is captured. (2) The captured two-dimensional code is converted into a URL. (3) Specify the converted URL and access it.

[0046] [S910] The user management server 21 provides the instruction screen to the user terminal 10 . FIG. 10 shows an example of the instruction screen. As illustrated in FIG. 10, an instruction screen 1000 includes a timeline 1010, elements 1022 to 1028 associated with the timeline 1010, and a button 1030. The elements associated with the timeline 1010 include a frame 1022a extracted from a range of a movie, an icon 1024a indicating that the frame is a representative frame, and a button 1028a for instructing playback from the beginning of the range. The representative frame 1022a is specified by the parameters included in the playback request received in step S905.

[0047] [S915] The user management server 21 receives a request to update an element in the instruction screen from the user terminal 10. Specifically, when the loading of the Web page that constitutes the instruction screen is completed, a request to update the elements displayed on the instruction screen is sent from the user terminal 10 to the user management server 21 by asynchronous communication.

[0048] [S920] The user management server 21 causes the user terminal 10 to update the elements in the instruction screen. FIG. 11 shows an example of the updated instruction screen. In the display example of FIG. 11, corresponding text 1026a, a frame 1022b, corresponding text 1026b, a frame 1022c, corresponding text 1026c, and elements associated with these have been added. The corresponding text 1026a is text corresponding to the speech that can be extracted from the range from which the representative frame is extracted, and is an auxiliary element that is not included in the preceding information. Frame 1022b, corresponding text 1026b, frame 1022c, and corresponding text 1026c are auxiliary elements that can be extracted from a movie but are not included in the preceding information. These are also auxiliary elements with a high relative priority (in this embodiment, the frequency of designation).

[0049] [S925] The user management server 21 acquires the instruction data from the user terminal 10 . Specifically, when a tap operation on the button 1030 is detected, an update request for an element displayed on the instruction screen is sent by asynchronous communication from the user terminal 10 to the user management server 21. Also, when a tap operation on the button 1028 displaying "Play from here" is detected, the element designation data is sent from the user terminal 10 to the user management server 21. The request to update the elements displayed on the instruction screen may be configured to be automatically sent from the user terminal 10 as time passes.

[0050] [S930] The user management server 21 proceeds with the process according to the contents of the instruction data. Specifically, if the acquired instruction data is an "element update request", the process returns to step S920 above. On the other hand, if the acquired instruction data is data indicating an "element designation", the process proceeds to step S935 below.

[0051] When the instruction screen of FIG. 11 is displayed on the user terminal 10, if the button 1030 is tapped, an element update request is sent from the user terminal 10 to the user management server 21. FIG. 12 shows an example of the display of the instruction screen after the first update in response to a user operation. In the display example of FIG. 12, a frame 1022d, corresponding text 1026d, a frame 1022e, corresponding text 1026e, and elements associated with these are further added. A frame 1022d, corresponding text 1026d, a frame 1022e, and corresponding text 1026e are auxiliary elements with low relative priority.

[0052] When the instruction screen of FIG. 12 is displayed on the user terminal 10, if the button 1030 is tapped, an element update request is sent from the user terminal 10 to the user management server 21. FIG. 13 shows an example of the display of the instruction screen after the second update in response to a user operation. In the display example of FIG. 13, a frame 1022f, corresponding text 1026f, and associated elements are further added. Frame 1022f and corresponding text 1026f are auxiliary elements with an even lower relative priority.

[0053] [S935] The user management server 21 determines the playback start position of the specified movie. Specifically, the "start position" of the range that includes the specified auxiliary element is determined as the playback start position. At this time, the "priority" of the text management information related to the specified auxiliary element is updated.

[0054] [S940] The user management server 21 provides the user terminal 10 with a URL with parameters for streaming playback of the designated movie. Specifically, text is generated by adding a parameter capable of identifying the determined playback start position to a URL for streaming playback of the designated movie, and the generated text is provided to the user terminal 10 as a redirect destination.

[0055] [S945] The distribution server 32 receives a playback request from the user terminal 10. In the playback request, a playback start position is specified. [S950] The distribution server 32 distributes the designated movie to the user terminal 10 by streaming from the playback start position.

[0056] [3. Modifications] [3-1. Variations regarding priority] In the above embodiment, the number of times the playback start position is specified by the user is used as the "priority." The "priority" is updated every time the playback start position is specified by the user. Alternatively, a configuration may be adopted in which "priority" is determined in advance. For example, it is possible to set importance for objects such as people, and configure the "priority" to be higher in a range in which video and audio of objects with higher importance are recorded. This configuration is particularly effective when the number of users who can watch a movie is limited.

[0057] [3-2. Variations in information processing division] In the above embodiment, a configuration is adopted in which various data processes are executed by the content management system 20 (particularly the data processing server 22). The user terminal 10 plays a role equivalent to an input / output device of the content management system 20. Alternatively, a configuration may be adopted in which at least a part of these data processes is executed by the user terminal 10. For example, a process of extracting frames and sounds from a movie, extracting the extracted sounds, If the user terminal 10 executes a process such as performing a voice recognition process on the speech to obtain corresponding text, it becomes possible to reduce the processing load on the content management system 20 (data processing server 22).
