FIG. 13 shows a display example of the instruction screen after the second update according to the user operation.
In the display example of FIG. 13, a frame 1022f, corresponding text 1026f, and elements associated therewith are further added.
The frame 1022f and the corresponding text 1026f are auxiliary elements having a lower relative priority.

[S935]
The user management server 21 determines the playback start position of the designated movie.
Specifically, the “start position” of the range including the designated auxiliary element is determined as the reproduction start position. At this time, the “priority” of the text management information related to the designated auxiliary element is updated.

[S940]
The user management server 21 provides the user terminal 10 with a URL with parameters for streaming playback of the specified movie.
Specifically, a text to which a parameter that can specify the reproduction start position determined in the URL for streaming reproduction of the specified movie is generated and provided to the user terminal 10 as a redirect destination.

[S945]
The distribution server 32 receives a reproduction request from the user terminal 10. In the reproduction request, the reproduction start position is designated.
[S950]
The distribution server 32 performs streaming distribution of the designated movie to the user terminal 10 from the reproduction start position.

[3. Modified example]
[3-1. Modified example of priority]
In the above embodiment, a configuration is employed in which the number of times designated by the user is used as the “priority”. The “priority” is updated every time the reproduction start position is designated by the user.
On the other hand, a configuration in which “priority” is determined in advance may be employed. For example, an importance level may be set for an object such as a person, and the “priority” may be configured to be higher in a range in which video and audio of an object with higher importance are recorded. This configuration is particularly effective when the number of users who view the movie is limited.

[3-2. Modification regarding information sharing]
In the above embodiment, a configuration is employed in which the content management system 20 (particularly the data processing server 22) executes various data processing. The user terminal 10 plays a role corresponding to the input / output device of the content management system 20.
On the other hand, a configuration in which the user terminal 10 executes at least a part of these data processes may be employed. For example, the processing load of the content management system 20 (data processing server 22) can be achieved by causing the user terminal 10 to execute processing for extracting frames and audio from a movie, processing for performing speech recognition processing on the extracted audio to obtain corresponding text, and the like. Can be suppressed.
