As shown in FIG. 1, the comment management system 100 includes a comment management server 10, user terminals 21 to 2N (N is an arbitrary integer), and a content distribution server 30. The comment management server 10, the user terminals 21 to 2N, and the content distribution server 30 are connected by a communication network 40 such as the Internet.

  The comment management server 10 is managed by a system administrator of the comment management system 100, for example, and is configured by an information processing apparatus such as a WWW server. Further, the comment management server 10 performs processing for transmitting / receiving various information related to comments via the user terminals 21 to 2N and the communication network 40, and aggregates the received comment information to display the comment status on the user terminals 21 to 2N. For example, it has a function of executing various processes such as a process of generating comment status information for the user and a process of transmitting the generated comment status information to the user terminals 21 to 2N.

  The comment management server 10 includes a comment information DB 11 and a comment count information DB 12. The comment information DB 11 and the comment count information DB 12 may be provided inside the comment management server 10 or may be provided outside.

  The comment information DB 11 is a storage medium for storing detailed contents of comments transmitted from the user terminals 21 to 2N.

  FIG. 2 is an explanatory diagram illustrating a storage example of comment information stored in the comment information DB 11. As shown in FIG. 2, the comment information includes a content ID that can uniquely identify content, a user ID that can uniquely identify a user, a type that indicates a comment input type, and comment content that indicates comment content. , Including posting timing.

  Here, “posting timing” is information indicating elapsed playback time that represents elapsed time based on the head position (start position) of the content at the time of comment posting (input). That is, when the user inputs a comment after the content has been played for 72 seconds from the start position, the “posting timing” included in the comment information is “72 seconds”.

  The comment count information DB 12 is a database that stores comment count information set for each content. The comment count information is information that specifies the number of comments per second of the playback time of each content. The comment count information is sequentially updated in response to the comment management server receiving input comment information from the user terminals 21 to 2N.

  FIG. 3 is an explanatory diagram showing a storage example of the comment count information stored in the comment count information DB 12. As shown in FIG. 3, the comment count information includes a content ID, a count category, and the number of comments.

  Here, the “count division” is information divided at a predetermined interval by the total content reproduction time, and is divided every second from the start position (head position) to the end position of the content. Taking the case where the playback time of the content is 300 seconds (5 minutes) as an example, as shown in FIG. 3, the “playback period” is “0 second to less than 1 second”, “1 second to less than 2 seconds”. , “2 seconds or more and less than 3 seconds”,..., “298 seconds or more and less than 299 seconds”, and “299 seconds or more and less than 300 seconds”, and divided into 300 sections in units of 1 second.

As shown in FIG. 5, the playback section information includes a playback section and the number of comments (total) indicating the total number of comments in the playback section. The playback section information generation process executed by the comment management server 10 will be described in detail later.

  The content distribution server 30 is configured by an information processing device such as a WWW server, for example. The content distribution server 30 includes a database for storing the content to be distributed, receives the content distribution request from the user terminals 21 to 2N, and distributes the content stored in its own database to the user terminals 21 to 2N. It has a function to execute processing.

  Here, the “content” distributed by the content distribution server 30 includes, for example, various information such as a moving image, an electronic book, and audio data.

  Next, the operation of the comment management system 100 of this example will be described. Note that detailed descriptions of processes not particularly related to the present invention may be omitted. Also, in this example, a case where the content distribution server 30 distributes a moving image as content to the user terminal 21 will be described as an example.

  FIG. 6 is a flowchart illustrating an example of comment management processing executed by the comment management system 100. In the comment management process executed by the comment management system 100, the comment received by the user terminal 21 is displayed on the display device of the user terminal 21, and the process for displaying the comment input status is also executed.

  In the comment management process, first, the user terminal 21 reproduces a moving image distribution request to the content distribution server 30 or a moving image stored in its own storage unit 214 (step S101).

  When the moving image is reproduced, the user terminal 21 receives an input of a comment for the moving image to be reproduced from the user (step S102).

  When receiving an input of a comment from the user, the user terminal 21 executes a process for generating input comment information based on the comment that has received the input (step S103). FIG. 7 is an explanatory diagram illustrating an example of input comment information generated by the input comment information generation process. As shown in FIG. 7, the input comment information includes a content ID that can uniquely identify the content being played back, a user ID that can uniquely identify the user, the input type of the input comment, and input. Comment content and a playback elapsed time representing an elapsed time based on the head position (start position) of the content. The content ID is specified by acquiring a content ID used when receiving a moving image. Also, the user ID is specified by accepting in advance a login process (a login process that has undergone a user registration process) for enabling viewing of a moving image. In addition, about the identification method of content ID and user ID, it is not restricted to such a method, You may use another method.

  When the input comment information is generated by the input comment information generation process, the user terminal 21 transmits the input comment information to the comment management server 10 (step S104).

  When the comment management server 10 receives the input comment information transmitted from the user terminal 21 (step S105), the comment management server 10 stores the input comment information in the comment information DB (step S106).

  When the input comment information is stored in the comment information DB, the comment management server 10 updates the comment count information with reference to the stored input comment information (step S107). FIG. 8 is an explanatory diagram showing an example of updating the comment count information when the comment management server 10 receives the input comment information shown in FIG. As shown in FIG. 8, the comment management server 10 adds 1 to the count value associated with “72 seconds or more and less than 73 seconds” of the count category to which “72 seconds” belongs, and from “5” to “ To 6 ”.

  When the comment count information is updated, the comment management server 10 executes a process of generating playback section information based on the updated comment count information (step S200).

  FIG. 9 is a flowchart illustrating an example of the playback section information generation process executed by the comment management server 10. In the playback section information generation process, a process of generating playback section information indicating the number of posted comments in the playback section of a predetermined content is executed.

  In the playback section information generation process, first, the comment management server 10 specifies a playback section for dividing a moving image that has received a comment input into a plurality of sections based on the playback time (step S201). In the playback section information generation process in this example, the comment management server 10 specifies a playback section that is divided into one segment with a playback time of 1 minute. Therefore, for a 300-second video, the comment management server 10 determines that “0 to 60 seconds”, “60 to 120 seconds”, “120 to 180 seconds”, “180 to 240 seconds”, And five playback sections of “240 seconds or more and less than 300 seconds” are specified.

  When the playback section is specified, the comment management server 10 refers to the comment count information and sums the count value accumulated in the comment count information for each playback section (step S202). That is, the comment management server 10 specifies the playback section information indicating the number of comments in a predetermined playback section with reference to the comment count information updated with the transmitted input comment information.

  When the count value is added for each playback section, the comment management server 10 generates playback section information and stores it in its own playback section information database 13 (step S203).

  When the comment management server 10 generates the playback section information, the playback section information generation process is terminated and the process returns to the comment management process.

  Returning to the comment management process, the comment management server 10 transmits the playback section information generated by the playback section information generation process to the user terminal 21 (step S108).

  When receiving the playback section information transmitted from the comment management server 10 (step S109), the user terminal 21 displays the comment status information based on the received playback section information (step S110).

  FIG. 10 is a screen diagram showing an example of a display screen that displays comment status information based on the playback section information shown in FIG. As shown in FIG. 10, the display screen 300 includes a moving image display area 301, comments 302 and 303, a seek bar 304, a slider 305, and comment status information 306.

  The moving image display area 301 is an area for displaying a moving image received from the content distribution server. The moving image display area displays moving images and the text posted on the user terminals 21 to 2N as comments 302 and 303. In this example, the comments 302 and 303 are displayed so as to flow from the right to the left of the moving image display area, and the comments are displayed so as to enter from the outside of the screen and disappear from the screen.

  The comment 302 is displayed by synchronizing the comment information received from the comment management server 302 with the playback elapsed time of the moving image. More specifically, the case where the input comment information shown in FIG. 7 is received will be described as an example. When the user terminal 21 receives “72 seconds” as the elapsed playback time of the moving image, FIG. As shown in, a comment 303 “Chiro! Do your best!” Is displayed.

  The seek bar 304 includes a slider 305. The seek bar 304 is a display object that displays a slider 305 that moves in accordance with the elapsed playback time of the moving image so that it is possible to visually grasp how far from the beginning to the end of the moving image is being played. is there.

  The slider 305 is a display object that can freely change the playback position of a moving image in response to receiving a predetermined operation (for example, a slide operation).

  The comment status information 306 is information indicating the input status of a comment for each content playback section. The comment status information is displayed in a graph based on the playback section information shown in FIG. 5 in a display mode having a height corresponding to the number of comments in each section (that is, the first section to the fifth section). That is, the comment status information is displayed low in the section with a small number of comments and is displayed high in the section with a large number of comments. According to such a configuration, the user terminal 21 can reproduce the content by a display method that makes it possible to grasp at a glance which part of the moving image to be reproduced has a large number of comments and is an exciting part. become.

  As shown in FIG. 10, the user terminal 21 displays the comment status information 306 in association with the seek bar 304. That is, the user terminal 21 displays the comment status information 306 at a position where the comment status information 306 is overlapped with the seek bar 304 or a position orthogonal to the extension direction of the seek bar. As shown in FIG. 10, the comment status information 306 in this example is displayed at a position directly above the playback section of the seek bar. According to such a configuration, it is easy to move the playback position to a portion where the number of comments is large, and the convenience for the user is greatly improved. Although the display mode of the comment status information 306 in this example is displayed in a graph style, the comment status information 306 may be displayed in an indicator style that indicates that the number of comments can be grasped on a scale.
