To do. The transmission unit 40 has a function of transmitting various information to the comment distribution server 2 and the moving image distribution server 1 in accordance with the instruction input from the input unit 37.

Next, the operation of the comment distribution system described above will be described. Here, first, an 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 whose comment writing times are recent, and displays them on the display device 34. At this time, for example, the display device 34 displays a moving image name, a thread name, etc. as a recent moving image list as shown in FIG. Here, when a thread to be browsed is selected by the user and the name of the thread is clicked with the mouse, the terminal device 3 sends the video ID set to the video corresponding to the clicked thread to the video distribution server 1. The video is transmitted and a moving image distribution request is made, and the thread ID and the moving image ID set for the clicked thread are transmitted to the comment distribution server 2 to request transmission of comment information. Receiving this, the moving image distribution server 1 performs streaming distribution of the moving image specified by the moving image ID to the terminal device 3 that has requested 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 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, in accordance with the moving image reproduction time after starting the reproduction of the moving image, the comment contents in which the comment addition time that matches the moving image reproduction time is sequentially displayed on the moving image.

Next, operations of the comment distribution server 2 and the terminal device 3 will be described sequentially.
First, operation | movement of the comment delivery server 2 is demonstrated using the flowchart of FIG. The communication unit 24 of the comment distribution server 2 detects whether or not a 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 moving image 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 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. Distribute (step S103). Here, each comment information associated with the moving image ID and the thread ID is transmitted in a lump.

  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, identifies the comment information based on the video ID and thread ID included in the comment data output from the communication unit 24, and for the identified comment information, The received comment data is additionally stored (step S105). When the additional information is stored, the comment information distribution unit 22 reproduces the video with the video ID, and the terminal device 3 viewing the comment with the thread ID together with the video with the video ID. The identified comment data is distributed to each of the identified terminal devices 3 (step S106). On the other hand, if it is not a comment information distribution request and the comment data transmitted from the terminal device 3 has not been received, the process proceeds to step S101. Here, as a method of identifying the terminal device 3 that is playing a video with the same video ID and is browsing the comment of the thread with the thread ID, for example, the terminal device 3 that has accessed the comment distribution server 2 And a session is established, and the terminal device 3 in which the session is valid is identified as being viewing a moving image.

Next, operation | movement of the terminal device 3 is demonstrated using drawing. FIG. 8 is a flowchart for explaining the operation of the terminal device 3.
When an instruction for reproducing a moving image is input from the user (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 a moving image distribution request. In addition, a comment information distribution request is transmitted to the comment distribution server 2. And the comment information receiving part 32 will memorize | store it in the comment information storage part 33, if the comment information delivered from the comment delivery server 2 is received (step S202).

When the comment information is received and stored in the comment information storage unit 33, the video reproduction 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. The information is 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 addition time that matches the moving image reproduction time is set based on the current moving image reproduction time. It judges with reference to the part 33 (step S204). When there is comment data in which the comment addition time that matches the video playback 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 is performed on the moving image according to the calculated display position (step S206).
On the other hand, the moving image playback unit 31 determines whether or not the playback has ended. If the playback has ended, the video playback unit 31 ends the processing. If the playback has not ended, the moving image playback unit 31 proceeds to step S204.

  On the other hand, if there is no comment to be displayed in step S205, the distribution unit 40 detects whether or not a comment is input from the input unit 37 (step S209). When a comment is input, the playback time pointed to 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 out, the video playback time is set as the comment giving time, the video ID of the video being played back, the thread ID of the comment being browsed, the current real-time information (current time information), and the terminal The user name of the user of the apparatus 3, the input comment content, and the comment display method are associated with each other and additionally stored as comment information in the comment list of the comment information storage unit 33 (step S210). Then, the transmission unit 40 transmits the additionally stored comment information to the comment distribution server 2 (step S211), and proceeds to step S208.

  If it is not a comment input in step S209, the terminal device 3 detects whether or not comment data is 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, when the comment data is not received in step S212, the selection unit 38 of the terminal device 3 detects whether or not a comment selection operation has been input from the input unit 37 (step S214). When a comment selection operation is input, the selection unit 38 outputs the comment content of the selected comment data to the reproduction control unit 39. In response to this output, the playback control unit 39 reads the comment addition time stored in association with the selected comment data with reference to the comment information storage unit 33, and the video playback time corresponding to the read comment addition time Accordingly, by rewinding or fast-forwarding the video playback position, playback is performed from the video playback time that matches the comment addition time stored in association with the comment data (step S215). The contents are displayed, and the process proceeds to step S208.

  Next, a case where a comment is displayed on the screen will be described with reference to the drawings. Here, a case will be described in which a thread “Let's say about cooking!” Associated with a video of “famous chef omelet rice” in “Recent comment list” of FIG. 5 is selected. When this thread is selected, a moving image of “famous chef's omelet rice” is reproduced, for example, in the area of the display column 104 in FIG. Then, comments are sequentially displayed on the moving image according to the moving image playback time. FIG. 5 shows a screen when the video playback time is 9 seconds. Here, the comment of user F who has commented for 9 seconds moves from the right side of the screen to the left side. Is displayed (reference numeral 115). Then, when the reproduction of the moving image proceeds and the moving image reproduction time reaches 13 seconds, a screen as shown in FIG. 9 is displayed. Here, the comment “Delicious!” Which is a comment with a 9 second comment time has moved to the left side of the screen and is “out of the display field 104 and trimmed inside the display field 109” "!" Is displayed (reference numeral 200). In addition, the comment of the user Z who has comment time of 10 seconds is displayed in the position below the comment of the user B (reference 201), and the comment time of comment is displayed. "Which egg are you using?" Which is a comment of the user E for 12 seconds is displayed at the lower position of the screen (reference numeral 202). In this way, comments are sequentially displayed.

As described above, the description has been made focusing on the operation of only one terminal device 3, but in practice, comments are exchanged as follows between users who are viewing the same thread and the same video. Can do. Here, description will be made with reference to FIG.
For example, when a video is played by a certain user E and a comment “Where are you using?” Is additionally input as a comment when the video playback time is 12 seconds (symbol a), the additional input The comment information of the comment that has been made is distributed via the comment distribution server 2 to the terminal device 3 that is the same moving image and is browsing the same thread.

  When the same moving image is reproduced by another user C after the distribution (reference symbol 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 the user E, “Which egg are you using?” Is displayed. Then, the user C who has read this comment, as the answer, “It seems to be produced in XX prefecture when the video playback time of the user C is 15 seconds (in the video playback time of the user E, for example, 100 seconds). Is input to the comment distribution server 2 (symbol 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, a part of the comment of the user C is displayed in the list of the comment list of the user E in the order according to the real time (symbol d). For example, the latest comment is displayed at the bottom (or top) of the comment list. When a part of the comment is clicked by the user E who has seen this comment list, the video being played back is played back at the time of the video playback time of 15 seconds, and the terminal device 3 of the user E A comment “It seems to be from XX prefecture” is displayed on the screen (reference e). As a result, the user E can enjoy it as if a reply was made to his / her comment. By repeating such exchange of comments, even users who are viewing moving images at different timings can communicate via comments. In this way, comments are managed in the order of comment input in real time and displayed as a list of comments, so even users who do not match the video playback timing can exchange comments in real time Can communicate with each other.

  Also, when such comment writing and video playback from the time the comment is written are repeated, the difference in video playback timing approaches 0 between users, and the same video is played at almost the same timing. Comments can be exchanged while browsing.

  Here, a case where a plurality of users are viewing the same video has been described. However, if a user plays a video in a situation where no user is viewing the video, it is stored until then. The comment information that has been made 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. Thereby, even in a situation where no other user is browsing, comments made in the past can be browsed in order according to the video playback time of the video. Here, you can also write a comment.

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. The case where a comment is displayed has been explained, but if the added comment is not clicked, when the video playback time reaches the comment grant time set for the added comment, the comment is displayed on the video. Is displayed.
Also, even if a comment is written by another user during the video playback time of the video you are browsing, it will be displayed in the comment list in real time order, so click on the added comment The user can view the comment by rewinding or fast-forwarding to the point when the comment is written. Also, here, by rewinding the video playback time, the comments written so far, including newly written comments, are sequentially displayed according to the video playback time according to the comment grant time. Is done.

Also, here, it is possible to rewind and fast forward the playback time by moving the slide bar in the playback status display field of the operation panel 106, but in this operation, the video is rewound or fast forwarded. The comment that you want to see disappears from the screen immediately, and it may be difficult to find it, but you can select it from the comment list to see it from the scene you want to see.
In the above-described embodiment, the case has been described in which the terminal device 3 receives the comment data distributed from the comment distribution server 2 and displays the comment data on the screen. The comment may be displayed on the screen as soon as the comment is input (before being sent to the comment delivery server 2 and received by the comment delivery 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 stored in the comment list. Then, it may be transmitted to the comment distribution server 2.

Next, comment display will be described.
The input comment can be set by inputting a display position such as an upper stage, a middle stage, and a lower stage on the screen and a display time for moving and displaying the comment in the input field 109. Further, when setting the display time, for example, a comment can be displayed for a certain time (for example, 4 seconds) on the upper stage of the screen and can be erased. It is also possible to adjust the moving speed by designating the time from appearing in the display area of the screen to moving outside the area and disappearing (for example, 4 seconds). Also, if a large number of comments are input at a certain video playback time, etc., and they are displayed on the same height line, they can be displayed or moved by changing the height on the screen. It can be displayed. Also, if the moving speed varies 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 having a different height or may be displayed in a moving manner.

  In addition to inputting a sentence, a comment can be arranged with characters, symbols, and the like, 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 depiction or a real image by unchecking “one line” in the check box 114 and describing characters and symbols over several lines. Here, the character font may be enlarged or reduced as necessary so that all the lines of ASCII art fit within the screen.

  Also, based on the actual time, it may be determined whether the comment is new or old, and the comment input at the old time in the actual time may be displayed semi-transparently after a certain time, and then deleted. Also, 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 route 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, comments with high importance may be displayed on the upper line of the screen, and comments with lower importance may be displayed on the lower line of the screen.

In the above-described embodiment, the case where the video distribution server 1 and the comment distribution server 2 are separate servers has been described. However, the functions of the video distribution server 1 and the comment distribution server 2 are realized by the same server. You may do it.
In the above-described embodiment, when viewing comments and videos in this service, the comment distribution server 2 is accessed to receive the latest comment list data, and the latest display displayed on the display device 34. Although the case where a video and a thread are selected from the comment list has been described, the video may be designated as a thread, a URL for viewing the comment and the video may be created, and may be published on the Internet. Specifically, the video ID and thread ID are included, and when clicked, a URL that allows the playback of the video and the comment information of the thread to be received is written on a bulletin board on a blog or an Internet site. You may make it make a user click. Further, such a URL may be set in a thumbnail image or the like and clicked.

  In addition, regarding such a recent comment list, on the screen (for example, FIG. 5) where the video and the comment are viewed, a thumbnail image is displayed on the right side or the lower side of the screen, and a thread with a large number of accesses is displayed. The thread may be displayed as a ranking, clicked by the user, and a thread set in the clicked thumbnail image may be displayed.

  In the above-described embodiment, the case where the moving image ID and the thread ID are designated has been described. However, when the representative thread ID is registered in advance for the moving image ID and only the moving image ID is designated, the representative thread is displayed. You may do it. Further, when a comment is simply input to a moving image without specifying which thread is to be written, the representative thread may be written. Further, when a certain number of comments (for example, 100) are remarked in the thread, a new thread may be generated by the comment distribution server 2 or the user.

  In addition, regarding the comment list, for comments that have been displayed once on the video, or for items that the user has clicked and viewed from the comment list, it can be specified in the comment list that they have been viewed. May be. For example, the character color may be changed, or a mark indicating that browsing has been completed may be displayed.

Further, an individual user identifier may be assigned to each user, and for example, a comment may be made by associating a user identifier with a comment. Thereby, it is possible to identify who commented. Furthermore, the comment may be displayed in a different character color according to the user identifier. This makes it possible to identify the user who has spoken.
In addition, by assigning a user ID to users who have accessed the system in advance and storing the user ID in the comment data, it is possible to display a list of comments made by each user by, for example, pop-up display. . This user ID may be assigned to each user by prior user registration, or information for identifying a terminal device may be used. When using information for specifying the terminal device, for example, a calculation may be performed by a hash function based on information for specifying the terminal device, and the calculation result may be used as the user ID.

  Next, a second embodiment will be described. In this embodiment, a case where a posted comment is deleted will be described. For example, the comment is erased so that the comment to be erased is not displayed on the screen in response to a comment erase instruction input via the terminal device 3 from a user who has the authority to delete the comment. be able to. In addition, even for users who do not have the authority to delete comments directly, depending on the number of comment deletion requests from users who do not have that authority, the comment will be in a semi-transparent state or will not be displayed. Is possible.

Hereinafter, a comment distribution system according to the second embodiment will be described.
FIG. 11 is a schematic block diagram showing functions of the comment delivery system in the second embodiment. In this figure, the same reference numerals are given to portions corresponding to the respective portions in FIG. 2, and description thereof is omitted. In this embodiment, description will be made assuming that a comment ID is assigned to each comment of comment information.
In addition to the functions of the communication unit 24 in FIG. 2, the communication unit 241 further receives comment deletion request information transmitted from the terminal device 3. The comment erasure request information here includes a comment ID to be erased, a thread ID for identifying a thread in which the comment to be erased is registered, a video ID for identifying a video corresponding to the thread, and an erase An erasure request user ID for identifying the user who made the request is included.

The comment information update management unit 23 includes 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 video ID, the thread ID, and the deletion request user ID included in the comment deletion request information. It is determined whether or not the user has authority to do so. The authority determining unit 231 stores an authority table for determining whether or not this authority is present in a memory area inside the authority, and refers to this table to determine whether or not the authority is present. An example of this authority table is shown in FIG. As shown in FIG. 12, the authority table stores a moving image ID, a thread ID, and a deletion authority possessing user ID for identifying a user who has the authority to delete a comment registered in the thread ID. . Here, only one deletion authority possessing user ID may be stored for one combination of the moving image ID and thread ID, or a plurality of deletion authority possessing user IDs may be stored. The authority determining unit 231 refers to this authority table, determines whether the combination of the movie ID and the comment ID included in the comment deletion request information is in the authority table, and if there is a movie ID and a comment ID, , It is determined whether or not the erasure authority possessing user ID associated with the comment ID of the authority table matches the user ID included in the comment erasure request information, and is included in the erasure authority possessing user ID and the comment erasure request information If the user ID matches, the user ID is determined to have the authority to delete the comment.

The erasure request count unit 232 counts the number of erasure requests for each comment requested to be erased based on the comment erasure request information determined by the authority determination unit 231 not to have erasure authority.
The display database 234 stores the count number and the display method in association with each other. An example of information stored in the display database 234 is shown in FIG. Here, 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 information specifying the display method are stored in association with each other. As the display method, “normal” for displaying a comment, “semi-transparent” for displaying a comment semi-transparently on a moving image, and “transparent” for erasing the comment are set.

  The display selection unit 233 reads 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. And stored in the comment information storage unit 21.

Next, the operation of the comment delivery system in the second embodiment described above will be described.
FIG. 14 is a sequence diagram for explaining the operation of the comment delivery system in 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 video and a comment on the screen. .
When the user clicks on a comment to be deleted among the comments displayed on the screen of the terminal device 3 with a mouse or the like, and clicks the deletion request button displayed on the screen, the terminal device 3, the comment ID, moving image ID, and thread ID of the clicked comment are read from the comment information storage unit 33, and the read comment ID, moving image ID, thread ID, and the user of the user who uses his / her terminal device 3 The ID is associated and transmitted to the comment distribution server 1 as a comment erasure request (step S301).

  When the comment distribution server 1 receives the comment deletion request information from the terminal device 3 (step S401), it determines whether the user ID included in the received comment deletion request information has the authority to delete the comment. Determination is performed by the determination unit 231 (step S402). As a result of the determination, if the user has deletion authority, the display selection unit 233 is instructed to delete the comment. In response to the instruction from the authority determination unit 231, the display selection unit 233 matches the video ID, thread ID, and comment ID included in the received comment deletion request information, and stores the comment stored in the comment information storage unit 21. Information indicating “not display” is written in the “comment display method” of the information.

  When the “comment display method” information in 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, erased comments are stored as comment data, but are not displayed on the screen, and comments that are not to be erased are displayed on the screen.

  On the other hand, if it is determined in step S402 that there is no authority, the erasure request count unit 232 detects the comment erasure request information from the user who does not have the erasure authority. Then, the erasure request counting unit 232 counts up the erasure request for the comment ID of the moving image ID and the thread ID included in the comment erasure request information (step S405), temporarily stores it in its own counter, and displays the count result. The data is output to the display selection unit 233. The display selection unit 233 reads the display method corresponding to the number of counts from the display database 234 based on the count result output from the erasure request count unit 232 (step S406), and the read display method is the moving image ID and thread ID. Write “comment display method” in 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). Thereby, 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 authority. Accordingly, it is possible to display a comment that takes into account the intention of a user having special authority, such as a manager of the thread, as to whether or not the comment is not suitable for the thread. Also, even a user who does not have the authority to delete a comment only by his / her own will be able to display the comment differently from other comments, such as deleting the comment or translucent depending on the number of users. . As a result, comments can be written or 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 count units 232 may be provided in the comment information update management unit 23. That is, it is possible to delete a comment by accepting a deletion request only from a user having deletion authority, and depending on the number of deletion requests received from the user regardless of whether or not the comment deletion authority exists. The comment may not be displayed or may be made translucent.

Further, in the second embodiment described above, the case where the comment display method is “normal”, “semi-transparent”, or “transparent” has been described, but the comment to be deleted is displayed differently from the normal comment. For example, change the translucency level to multiple levels, change the color of the comment, change the font size, font of the character, color gradation, or make it white. Also good.
Further, an input of a comment erasure cancellation request may be received from a user who has the authority to erase a comment, and the erased comment may be displayed in response to this instruction.

  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 playback unit 31 and the comment information in FIG. The receiving unit 32, the first display unit 35, the second display unit 36, the input unit 37, the selection unit 38, the reproduction control unit 39, the transmission unit 40, the authority determination unit 231, the erasure request count unit 232 in FIG. 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 into a computer system and executed to distribute comments. Comment display control may be performed. Here, the “computer system” includes an OS and hardware such as peripheral devices.

  Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case, and a program that holds a program for a certain period of time are also included. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.

  The embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and includes designs and the like that do not depart from the gist of the present invention.
