Further, the transmission unit 40 has a function of transmitting various information to the comment distribution server 2 and the video distribution server 1 according to the instruction input from the input unit 37.

Next, the operation of the comment distribution system described above will be described. Here, first, the outline of the operation of the comment distribution system will be described.
First, the terminal device 3 accesses the comment distribution server 2, receives data of a list of moving images having a recent comment writing time, and displays the data on the display device 34. At this time, for example, the display device 34 displays a moving image name, a thread name, or the like as a recent moving image list as shown in FIG. Here, when the user selects the thread to be viewed and the name of the thread is clicked with the mouse, the terminal device 3 transfers the video ID set in the video corresponding to the clicked thread to the video distribution server 1. It sends and requests the distribution of the moving image, and at the same time, sends the thread ID and the moving image ID set in the clicked thread to the comment distribution server 2 and requests the transmission of the comment information. In response to this, the video distribution server 1 streams the video specified by the video ID to the terminal device 3 that has requested the distribution. On the other hand, the comment distribution server 2 reads the comment information corresponding to the thread ID and the moving image ID from the comment information storage unit 21 and distributes the comment information to the terminal device 3 that has requested the distribution.

The terminal device 3 receives the moving image distributed from the moving image distribution server 1 and displays it on the display device 34, and displays the comment content on the moving image based on the comment information distributed from the comment distribution server 2. Here, according to the video playback time after the start of video playback, the comment content in which the comment giving time matching the video playback time is set is sequentially displayed on the video.

Next, the operations of the comment distribution server 2 and the terminal device 3 will be sequentially described.
First, the operation of the comment distribution server 2 will be described with reference to the flowchart of FIG. The communication unit 24 of the comment distribution server 2 detects whether or not the comment information distribution request has been received from the terminal device 3 (step S101). When the comment information distribution request is received, the communication unit 24 instructs the comment information distribution unit 22 to distribute the comment information. Here, the video ID and thread ID of the comment information included in the distribution request are output to the comment information distribution unit 22. The comment information distribution unit 22 reads the comment information corresponding to the moving image ID and the thread ID output from the communication unit 24 from the comment information storage unit 21 (step S102), and sends the read comment information to the terminal device 3 that has requested distribution. Deliver (step S103). Here, each comment information associated with the moving image ID and the thread ID is collectively transmitted.

On the other hand, when the comment data transmitted from the terminal device 3 is received instead of the comment information distribution request (step S104), the communication unit 24 outputs the comment data to the comment information update management unit 23. The comment information update management unit 23 refers to the comment information storage unit 21, specifies comment information based on the video ID and thread ID included in the comment data output from the communication unit 24, and with respect to the specified comment information. The received comment data is additionally saved (step S105). When additionally saved, the comment information distribution unit 22 is a terminal device 3 that is playing a video of the video ID and is viewing a comment of the thread ID together with the video of the video ID. The comment data that has been specified and additionally stored is distributed to each of the specified terminal devices 3 (step S106). On the other hand, if the comment data transmitted from the terminal device 3 is not received instead of the comment information distribution request, the process proceeds to step S101. Here, as a method of specifying the terminal device 3 that is playing the video of the same video ID and is viewing the comment of the thread of the thread ID, for example, the terminal device 3 that has accessed the comment distribution server 2. And a session may be established, and the terminal device 3 for which this session is valid may be specified as viewing a moving image.

Next, the operation of the terminal device 3 will be described with reference to the drawings. FIG. 8 is a flowchart for explaining the operation of the terminal device 3.
When the user inputs an instruction to play a moving image (step S201), the input unit 37 of the terminal device 3 transmits the moving image ID of the instructed moving image to the moving image distribution server 1 by the transmitting unit 40, and requests the distribution of the moving image. At the same time, the comment information distribution request is transmitted to the comment distribution server 2. Then, when the comment information receiving unit 32 receives the comment information distributed from the comment distribution server 2 (step S202), the comment information receiving unit 32 stores the comment information in the comment information storage unit 33.

When the comment information is received and stored in the comment information storage unit 33, the video playback unit 31 receives the video distributed from the video distribution server 1, reproduces the received video, and displays it on the first display unit 35. Displayed on the device 34 (step S203). When the reproduction of the moving image is started, the first display unit 35 stores the comment information as to whether or not there is comment data in which the comment giving time matching the moving image reproduction time is set based on the current moving image reproduction time. A determination is made with reference to the unit 33 (step S204). When there is comment data in which the comment giving time matching the moving image reproduction time is set (step S205-YES), the first display unit 35 calculates the display position of the comment data (step S206). Then, the display control of the comment on the moving image is performed according to the calculated display position (step S206).
On the other hand, the moving image reproduction unit 31 determines whether or not the reproduction is completed, ends the process if the reproduction is completed, and proceeds to step S204 if the reproduction is not completed.

On the other hand, if there is no comment to be displayed in step S205, the distribution unit 40 detects whether or not the comment has been input from the input unit 37 (step S209). When a comment is input, the playback time indicated by the player of the software playing the video at the time when the comment is input (for example, when the "write" button (reference numeral 111) is clicked). (Video playback time) is read, and the video playback time is used as the comment grant time. The video ID of the video being played, the thread ID of the comment being viewed, the current real-time information (current time information), and the terminal. The user name of the user of the device 3, the input comment content, and the comment display method are associated with each other and additionally saved as comment information in the comment list of the comment information storage unit 33 (step S210). Then, the transmission unit 40 transmits the additionally saved comment information to the comment distribution server 2 (step S211), and proceeds to step S208.

In step S209, when the comment is not input, the terminal device 3 detects whether or not the comment data has been received by the comment information receiving unit 32 (step S212). When the comment data is received, the comment information receiving unit 32 additionally stores the received comment data in the comment information storage unit 33, and proceeds to step S208.

On the other hand, in step S212, when the comment data is not received, the selection unit 38 of the terminal device 3 detects whether or not the comment selection operation has been input from the input unit 37 (step S214). When the comment selection operation is input, the selection unit 38 outputs the comment content of the selected comment data to the reproduction control unit 39. Upon receiving this output, the reproduction control unit 39 reads out the comment addition time stored in association with the selected comment data with reference to the comment information storage unit 33, and the moving image reproduction time according to the read comment addition time. According to this, by rewinding or fast-forwarding the video playback position, playback is performed from the video playback time corresponding to the comment grant time stored in association with the comment data (step S215), and the comment of the comment grant time is performed. The contents are displayed, and the process proceeds to step S208.

Next, the case where the comment is displayed on the screen will be described with reference to the drawings. Here, a case where the thread "Let's say your impression of cooking!" Associated with the video of "Famous chef omelet rice" is selected in the "Recent comment list" of FIG. 5 will be described. When this thread is selected, the video of "famous chef omelet rice" is played, for example, in the area of the display field 104 in FIG. Then, the comments are sequentially displayed on the moving image according to the moving image reproduction time. FIG. 5 shows a screen when the video playback time is 9 seconds. Here, the comment of the user F whose comment addition time is 9 seconds, "It looks delicious!", Moves from the right side to the left side of the screen. It is displayed (reference numeral 115). Then, when the reproduction of the moving image progresses and the moving image reproduction time reaches 13 seconds, the screen as shown in FIG. 9 is displayed. Here, "It looks delicious!", Which is a comment with a comment addition time of 9 seconds, has been moved to the left side of the screen, and is trimmed to the outside of the display field 104 and the inside of the display field 109. Only the part of "...!" Is displayed (reference numeral 200). In addition, the comment "I like the work of the famous chef", which is the comment of the user Z whose comment giving time is 10 seconds, is displayed at the position below the comment of the user B (reference numeral 201), and the comment giving time. Is a 12-second user E comment, "Which egg are you using?" Is displayed at the bottom of the screen (reference numeral 202). In this way, the comments are displayed sequentially.

The above description has focused on the operation of only one terminal device 3, but in reality, comments are exchanged between users who are viewing the same video and the same thread as follows. Can be done. Here, a description will be given with reference to FIG.
For example, when a video is played by a certain user E and a comment "Which egg are you using?" Is additionally input as a statement when the video playback time is 12 seconds (reference numeral a), the additional input is made. The comment information of the comment is distributed to the terminal device 3 which is the same moving image and is viewing the same thread via the comment distribution server 2.

After the distribution, when the same moving image is played by another user C (reference numeral b), the comment information including the added comment is distributed to the terminal device 3 of the user C. Then, when the moving image playback time is 12 seconds, a comment from user E asking "Which egg are you using?" Is displayed. Then, the user C who browses this comment responds by saying, "It seems to be from XX prefecture" when the video playback time of the user C is 15 seconds (for example, when the video playback time of the user E is 100 seconds). When the comment "" is input and transmitted to the comment distribution server 2 (reference numeral c), the transmitted comment is distributed to the terminal device 3 of the user E. At this time, for example, when the moving image playback time is 100 seconds, some of the comments of the user C are displayed in the list of the comment list of the user E in the order according to the real time (reference numeral d). For example, the latest comment is displayed at the bottom (or top) of the comment list. Then, when a part of the comment is clicked by the user E who sees this comment list, the video being played is played back at the time point of the video playback time of 15 seconds, and the terminal device 3 of the user E is played. The comment "It seems to be from XX prefecture" is displayed on the screen (code e). As a result, the user E can enjoy himself as if he / she had a reply to his / her comment. Then, by repeating such exchange of comments, even users who are viewing the moving image at different timings can communicate with each other through the comments. In this way, comments are managed in the order of comment input in real time and displayed as a comment list, so even users whose video playback timings do not match can exchange comments in real time. And it becomes possible to communicate.

Further, when the writing of such a comment and the playback of the video from the time when the comment is written are repeated, the difference in the playback timing of the video approaches 0 among the users, and the same video is played at almost the same timing. You can exchange comments while browsing.

Here, we have described the case where multiple users are viewing the same video, but if a user plays a video in a situation where no one is watching the video, it will be remembered by then. The comment information that has been stored is distributed from the comment distribution server 2 to the terminal device 3, and is sequentially reproduced according to the timing of moving image reproduction. As a result, even if no one else is browsing, the comments made in the past can be browsed in order according to the video playback time of the video. You can also write comments here.

In the above-described embodiment, when a comment is added to the comment list and the added comment is clicked by the user, the comment is played from the video playback time that matches the comment grant time set in the comment. I explained the case where a comment is displayed, but if the added comment is not clicked, the comment will be displayed on the video when the video playback time reaches the comment grant time set for the added comment. Is displayed.
Also, even if a comment is written by another user during the video playback time of the video you are viewing, it will be displayed in the comment list in the order of real time, so click on the added comment. Allows you to view the comment by rewinding or fast-forwarding at the time the comment was written. Further, here, by rewinding the video playback time, the comments written so far, including the newly written comment, are sequentially displayed according to the comment addition time and according to the video playback time. Will be done.

Further, here, it is also possible to rewind and fast forward the playback time by moving the slide bar in the playback status display column of the operation panel 106, but with this operation, the moving image is rewound or fast forwarded. It may be difficult to find the comment you want to see because it disappears from the screen immediately, but you can see it from the scene you want to see by selecting it from the comment list.
Further, in the above-described embodiment, the case where the terminal device 3 receives the comment data distributed from the comment distribution server 2 and reflects it on the screen for display has been described, but the user inputs the comment data in the terminal device 3 itself. The comment may be displayed on the screen as soon as the comment is input (before being transmitted to the comment distribution server 2 and received by the comment distribution server 2). Specifically, when a comment is input in step S209 of FIG. 8, the input comment is displayed on its own terminal device 3, the process proceeds to step S210, and the input comment is additionally saved in the comment list. After that, it may be transmitted to the comment distribution server 2.

Next, the display of comments will be described.
The input comment can be set by inputting the position to be displayed such as the upper row, the middle row, the lower row on the screen, and the display time for moving and displaying the comment in the input field 109. When setting the display time, for example, the comment can be displayed for a certain period of time (for example, 4 seconds) at the upper part of the screen and then erased. It is also possible to adjust the movement speed by designating the time from appearing in the display area of the screen to moving out of the area and disappearing (for example, 4 seconds). Also, when a large number of comments are input in a concentrated manner during a certain video playback time, and if they overlap on the same height line when displayed, the height on the screen is changed and displayed or moved. It is possible to display it. Also, if the movement speed differs depending on the length of the comment character string due to the display time being set, the next comment may catch up before the comment finishes moving. In this case, the next comment may be displayed on a line at a different height or may be moved and displayed.

In addition to inputting sentences, comments can be arranged by arranging characters, symbols, etc., and ASCII art (also referred to as text art) can be input as a comment. In this case, it is also possible to draw a landscape description or a real image by unchecking "1 line" of the check box 114 and describing characters and symbols over several lines. Here, the character font may be enlarged or reduced as needed so that all lines of ASCII art fit on the screen.

Further, the old and new of the comment may be determined based on the real time, and the comment input at the old time in the real time may be displayed semi-transparently after a certain period of time, and then deleted. Further, the importance may be set for the comment, and the character size of the comment may be changed according to the importance. For example, if the number of response comments is large, it can be determined that the importance is high, and the character size of the root comment can be increased. Further, the display position of the comment in the vertical direction (vertical direction of the screen) may be changed according to the importance. For example, a comment with high importance may be displayed in the upper line of the screen, and a comment with low importance may be displayed in the lower line of the screen.

Although the case where the video distribution server 1 and the comment distribution server 2 are different servers has been described in the above-described embodiment, the functions of the video distribution server 1 and the comment distribution server 2 are realized on the same server. You may do so.
Further, in the above-described embodiment, when viewing comments and videos in this service, the comment distribution server 2 is accessed, the data of the recent comment list is received, and the latest displayed on the display device 34. The case of selecting a video and a thread from the comment list has been described, but you may specify a thread for this video, create a URL where you can view the comment and the video, and publish it on the Internet. Specifically, the URL that includes the video ID and thread ID and can be clicked to play the video and receive the comment information of the thread is written on the bulletin board on the blog or Internet site to other You may want the user to click. Further, such a URL may be set in a thumbnail image or the like so as to be clicked.

In addition, regarding such a recent comment list, on the screen for viewing videos and comments (for example, Fig. 5), thumbnail images are displayed on the right side or bottom of the screen, and threads with a large number of accesses are displayed. It may be displayed as a ranking, and the user may click it to display the thread set in the clicked thumbnail image.

Further, in the above-described embodiment, the case where the moving image ID and the thread ID are specified has been described, but the representative thread ID is registered in advance in the moving image ID, and when only the moving image ID is specified, the representative thread is displayed. You may do so. Further, if a comment is simply input to the video without specifying which thread to write to, the writing may be performed to the representative thread. Further, when a certain number of comments (for example, 100) are spoken in the thread, a new thread may be generated by the comment distribution server 2 or the user.

Also, regarding the comment list, if the comment is displayed once on the video, or if the user clicks and browses from the comment list, it can be specified in the comment list that it has been viewed. You may. For example, the character color may be changed or a mark indicating that the text has been viewed may be displayed.

Further, an individual user identifier may be assigned to each user, and for example, the user identifier may be associated with the comment to be used as comment data. This makes it possible to identify who made the comment. Further, the comment may be displayed in a different character color depending on the user identifier. This makes it possible to identify the user who has spoken.
Further, by assigning a user ID to a user who has accessed the system in advance and storing the user ID in the comment data, the comments made by each user may be displayed in a list by, for example, pop-up display. .. Note that this user ID may be assigned to each user by prior user registration, or information that identifies the terminal device may be used. When the information for specifying the terminal device is used, for example, the operation may be performed by a hash function based on the information for specifying the terminal device, and the calculation result may be used as the user ID.

Next, the second embodiment will be described. In this embodiment, a case of deleting a posted comment will be described. The erasure of the comment here is such that the comment to be deleted is not displayed on the screen in response to the comment erasure instruction from the user who has the authority to delete the comment, which is input via the terminal device 3, for example. be able to. Also, even if the user does not have the authority to delete the comment directly, the comment should be translucent or the comment should not be displayed depending on the number of comment deletion requests from the user who does not have the authority. Is possible.

Hereinafter, the comment distribution system according to the second embodiment will be described.
FIG. 11 is a schematic block diagram showing the functions of the comment distribution system according to the second embodiment. In this figure, the parts corresponding to the parts of FIG. 2 are designated by the same reference numerals, and the description thereof will be omitted. In this embodiment, it is assumed that a comment ID is assigned to each comment of the comment information.
In addition to the function of the communication unit 24 of FIG. 2, the communication unit 241 further receives the comment deletion request information transmitted from the terminal device 3. The comment deletion request information referred to here includes a comment ID to be deleted, a thread ID to specify a thread in which the comment to be deleted is registered, a video ID to specify a video corresponding to the thread, and an deletion. It includes an erasure request user ID for identifying the user who made the request.

The comment information update management unit 23 has an authority determination unit 231, an erasure request count unit 232, and a display selection unit 233.
The authority determination unit 231 receives the comment deletion request information received from the terminal device 3 by the communication unit 242, and deletes the comment based on the moving image ID, the thread ID, and the deletion request user ID included in the comment deletion request information. Determine if you have the authority to do so. The authority determination unit 231 stores an authority table for determining whether or not it has this authority in its own internal memory area, refers to this table, and determines whether or not it has the authority. An example of this authority table is shown in FIG. As shown in FIG. 12, the video ID, the thread ID, and the user ID having the erasing authority for identifying the user who has the authority to delete the comment registered in the thread ID are stored in association with each other in the authority table. .. Here, only one erasing authority-owning user ID may be stored for one combination of the moving image ID and the thread ID, or a plurality of erasing authority-owning user IDs may be stored. The authority determination unit 231 refers to this authority table, determines whether or not the combination of the video ID and the comment ID included in the comment deletion request information is in the authority table, and if there is a video ID and a comment ID, further. , It is determined whether or not the user ID with the erasure authority associated with the comment ID of the authority table and the user ID included in the comment erasure request information match, and the user ID with the erasure authority and the comment erasure request information are included. If the user ID matches the user ID, it is determined that the user has the authority to delete the comment.

The erasure request counting unit 232 counts the number of erasure requests for each comment requested for erasure based on the comment erasure request information determined by the authority determination unit 231 that the authority determination unit 231 does not have the erasure authority.
The display database 234 stores the count number and the display method in association with each other. FIG. 13 shows an example of the information stored in the display database 234. Here, the information indicating the relationship between the count number (n), which is the result of counting by the erasure request counting unit 232, and the range of the count number, and the information specifying the display method are stored in association with each other. As this display method, "normal" for displaying a comment, "semi-transparent" for displaying a semi-transparent comment on a moving image, and "transparent" for deleting a comment are set.

The display selection unit 233 reads out the display method corresponding to the count result (n) counted by the erasure request counting unit 232 with reference to the display database 234, and assigns the read display method to the "comment display method" of the comment information. , It is stored in the comment information storage unit 21.

Next, the operation of the comment distribution system in the second embodiment described above will be described.
FIG. 14 is a sequence diagram for explaining the operation of the comment distribution system according to the second embodiment.
First, as shown in the first embodiment, the comment distribution server 1 collects comments posted from the terminal device 3, distributes them as comment information to each terminal device 3, and displays a moving image and a comment on the screen. ..
Then, among the comments displayed on the screen of the terminal device 3, when the user clicks the comment to be deleted by the user with a mouse or the like and the deletion request button displayed on the screen is clicked, the terminal device 3 reads the comment ID, the moving image ID, and the thread ID of the clicked comment from the comment information storage unit 33, and the read comment ID, the moving image ID, the thread ID, and the user of the user who uses the own terminal device 3. It is associated with the ID and transmitted to the comment distribution server 1 as a comment deletion request (step S301).

When the comment distribution server 1 receives the comment deletion request information from the terminal device 3 (step S401), the comment distribution server 1 is authorized to determine whether or not the user ID included in the received comment deletion request information has the authority to delete the comment. Judgment is made by the determination unit 231 (step S402). As a result of the determination, if the user has the delete authority, the display selection unit 233 is instructed to delete the comment. The display selection unit 233 responds to the instruction from the authority determination unit 231 and matches the video ID, thread ID, and comment ID included in the received comment deletion request information, and the comment stored in the comment information storage unit 21. Write the information indicating "not displayed" in the "comment display method" of the information.

Then, when the information of the "comment display method" of the comment information is updated, the comment information distribution unit 22 transmits the updated comment information to the terminal device 3 (step S404). The terminal device 3 receives the comment information transmitted from the comment distribution server 1 and displays the comment according to the comment display method. Here, the deleted comment is stored as comment data, but is not displayed on the screen, and the comment that is not the deletion target is displayed on the screen.

On the other hand, if it is determined in step S402 that there is no authority, the erasure request counting unit 232 detects it as comment erasure request information from a user who does not have this erasure authority. Then, the erasure request counting unit 232 counts up the erasure requests of the video ID and the comment ID of the thread ID included in the comment erasure request information (step S405), temporarily stores them in its own internal counter, and stores the count result. Output to the display selection unit 233. The display selection unit 233 reads the display method corresponding to the count number from the display database 234 (step S406) based on the count result output from the erase request count unit 232, and sets the read display method as the moving image ID and the thread ID. Write the "comment display method" of the comment information storage unit 21 according to the comment ID.

When the comment display method is written in the comment information storage unit 21, the comment information distribution unit 22 transmits the comment information after the comment display method is written to the terminal device 3 (step S404). As a result, it is displayed on the terminal device 3 according to the transmitted comment information (step S302).

According to this embodiment, the comment is deleted according to the presence or absence of authority. As a result, it is possible to display a comment considering whether or not the comment is not suitable for the thread, considering the intention of a user having special authority such as the administrator of the thread. In addition, even a user who does not have the authority to delete a comment only by his / her own will can delete the comment or display it differently from other comments such as translucent depending on the number of the users. .. As a result, comments can be written and deleted among a plurality of users, and the entertainment of the thread can be improved.

In the second embodiment described above, the case where the erasure request count unit 232 refers to the comment erasure request information determined that the authority determination unit 231 does not have the erasure authority has been described. Only one of the request counting units 232 may be provided in the comment information update management unit 23. That is, the deletion request may be accepted only from the user who has the deletion authority to delete the comment, and the comment may be deleted according to the number of deletion requests received from the user regardless of whether or not the comment has the deletion authority. You may hide the comment or make it translucent.

Further, in the second embodiment described above, the case where the comment display method is "normal", "semi-transparent", and "transparent" has been described, but the comment to be deleted is displayed differently from the normal comment. If possible, for example, make the level of translucency multi-level, change the color of comments, change the font size, font of characters, gradation of color, and make it white. May be good.
Further, the deleted comment may be displayed in response to the input of the comment deletion cancellation request input from the user having the comment deletion authority.

Further, in the embodiment described above, the program for realizing the functions of the comment information distribution unit 22, the comment information update management unit 23, and the communication unit 24 in FIG. 2, or the video reproduction unit 31, comment information in FIG. Receiving unit 32, first display unit 35, second display unit 36, input unit 37, selection unit 38, reproduction control unit 39, transmission unit 40, authority determination unit 231 in FIG. 11, erasure request counting unit 232, display. A program for realizing the functions of the selection unit 233 and the communication unit 241 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read by the computer system and executed to distribute comments. You may control the display of comments. The term "computer system" as used herein includes hardware such as an OS and peripheral devices.

Further, the "computer system" includes the homepage providing environment (or display environment) if the WWW system is used. Further, the "computer-readable recording medium" refers to a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, and a storage device such as a hard disk built in a computer system.
