Next, the operation of the comment delivery system described above will be described. Here, first, an outline of the operation of the comment delivery system will be described.
First, the terminal device 3 accesses the comment distribution server 2, receives the data of the moving image list whose comment writing time is recent, and displays it on the display device 34. At this time, for example, a moving image name, a thread name, and the like are displayed on the display device 34 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 by the mouse, the terminal device 3 sends the moving picture ID set to the moving picture corresponding to the clicked thread to the moving picture distribution server 1 While transmitting, making a distribution request of the moving image, the thread ID and the moving image ID set in the clicked thread are transmitted to the comment distribution server 2, and a transmission request of the comment information is made. Receiving this, the video distribution server 1
The streaming distribution of the moving image specified by the moving image ID is performed to the terminal device 3 that has made the distribution request. On the other hand, the comment distribution server 2 reads out the comment information corresponding to the thread ID and the moving image ID from the comment information storage unit 21 and distributes it to the terminal device 3 which has made the distribution request.

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 since the start of video playback,
The comment content for which the comment giving time that matches the moving image reproduction time is set is sequentially displayed on the moving image.

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 using the flowchart of FIG.
The communication unit 24 of the comment distribution server 2 detects whether a distribution request for comment information has been received from the terminal device 3 (step S101). When the distribution request for the comment information 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 the comment information distribution unit 2
Output to 2. 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 S
102), distributes the read out comment information to the terminal device 3 which has made a distribution request (step S
103). Here, each piece of comment information associated with the moving image ID and the thread ID is transmitted collectively.

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

Next, the operation of the terminal device 3 will be described using the drawings. FIG. 8 is a flowchart for explaining the operation of the terminal device 3.
When an instruction to reproduce a moving image is input from the user, the input unit 37 of the terminal device 3 (step S2
01) The transmitting unit 40 transmits the moving image ID of the instructed moving image to the moving image distribution server 1, makes a distribution request for the moving image, and transmits a distribution request for comment information to the comment distribution server 2. Then, the comment information receiving unit 32 stores the comment information distributed from the comment distribution server 2 in the comment information storage unit 33 (step S202).

When the comment information is received and stored in the comment information storage unit 33, the video playback unit 31
The video delivered from the video delivery server 1 is received, and the received video is played back.
The display 5 is displayed on the display unit 34 (step S203). Once the video starts playing,
The first display unit 35 refers to the comment information storage unit 33 to determine whether there is any comment data for which a comment giving time that matches the moving image reproduction time is set based on the current moving image reproduction time. (Step S204). If there is comment data for which a comment addition time that matches the moving image reproduction time is set (YES in step S205), the first display unit 35 calculates the display position of the comment data (step S206). Then, in accordance with the calculated display position, display control of the comment is performed on the moving image (step S206).
On the other hand, the moving image reproduction unit 31 determines whether or not the reproduction is ended, and the processing is ended if the reproduction is ended, and the processing goes to step S204 if the reproduction is not ended.

On the other hand, if there is no comment to be displayed in step S205, the distribution unit 40 detects whether a comment is 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 the comment is input (for example, when the “write” button (symbol 111) is clicked) (Video playback time) is read out, the video playback time is set as the comment addition 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 stored as comment information in the comment list of the comment information storage unit 33 (step S210). Then, the transmitting unit 40 transmits the additionally stored comment information to the comment distribution server 2 (step S211), and step S208.
Migrate to

In step S209, when it is not an input of a comment, the terminal device 3 detects whether or not the 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, in step S212, when it is not reception of comment data, the selection unit 38 of the terminal device 3 detects whether or not there is an input of a comment selection operation from the input unit 37 (step S214). When the comment selection operation is input, the selection unit 38 outputs the content of the comment of the selected comment data to the reproduction control unit 39. Receiving this output, the reproduction control unit 39 reads the comment provision time stored in association with the selected comment data with reference to the comment information storage unit 33, and reproduces the moving image according to the read comment provision time. According to the above, the reproduction is performed from the moving image reproduction time that matches the comment addition time stored in association with the comment data by rewinding or fast-forwarding the moving image reproduction position (step S215). Display the contents, step S2
Migrate to 08.

Next, the case where a comment is displayed on the screen will be described using the drawings. here,
A description will be given of the case where the thread "Let's say the impression of the dish!" Associated with the video of "the famous chef's omelet rice" in the "recent comment list" of FIG. 5 is selected. When this thread is selected, a moving image of "a famous chef's omelet rice" is reproduced, for example, in the area of the display field 104 of FIG. Then, comments are sequentially displayed on the moving image according to the moving image playback time. FIG. 5 shows the screen in the case where the moving image playback time is 9 seconds, and in this case, "Good looks ~!" Which is the comment of the user F whose comment addition time is 9 seconds moves from the right side to the left side of the screen. It is displayed (reference numeral 115). Then, the reproduction of the moving image proceeds, and when the moving image reproduction time reaches 13 seconds, a screen as shown in FIG. 9 is displayed. Here, “Good looks ~!”, Which is a comment with a comment giving time of 9 seconds, moves to the left side of the screen and is trimmed outside the display column 104 and inside the display column 109, “Yes. Only the part of "!" Is displayed (symbol 200). In addition, while the comment of “the famous chef's work is good”, which is the comment of the user Z whose comment addition time is 10 seconds, is displayed at the position below the comment of the user B (reference numeral 201) “Which egg are you using?”, Which is a 12-second comment of the user E, is displayed at the lower position of the screen (reference numeral 202). In this way, comments are sequentially displayed.

In the above, the description has been given focusing on the operation of only one terminal device 3. Actually, comments are exchanged as follows between users who are the same moving image and who are viewing the same thread. Can. Here, description will be made with reference to FIG.
For example, if a user E plays back a video and the video playback time is 12 seconds and the comment “Which egg are you using?” Is additionally input as a message (symbol a), the additional input The comment information of the comment that has been commented is distributed via the comment distribution server 2 to the terminal device 3 that is browsing the same thread that is the same moving image.

When the same moving image is reproduced by another user C after the distribution (code b), the user C
The comment information including the added comment is distributed to the terminal device 3 of. Then, when the moving image reproduction time is 12 seconds, a comment from the user E “Which egg are you using?” Is displayed. Then, the user C who browsed this comment has, as a reply, "It seems that" ○○ prefecture is produced "at the time when the moving image reproduction time of the user C is 15 seconds (for example, 100 seconds in the moving image reproduction time of the user E). When a comment “is input and transmitted to the comment distribution server 2 (code c), the transmitted comment is distributed to the terminal device 3 of the user E. At this time, for example, when the moving image reproduction time is 100 seconds, a part of the comments of the user C is displayed in the order according to the real time in the list of the comment list of the user E (symbol 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 has seen the comment list, the moving image being reproduced is returned to the time of 15 seconds of the moving image reproduction time and reproduced, and the terminal device 3 of the user E
On the screen of, a comment of “It seems to be a product of 県 prefecture” is displayed (symbol e). by this,
The user E can enjoy it as if his / her comment was answered. And by repeating exchange of such a comment, it becomes possible to plan communication via a comment even between the users who are viewing the moving image at different timings. As described above, comments are managed in the order of comment input in real time, and are displayed as a comment list. Therefore, even between users who do not match the playback timing of the moving image, exchange comments in real time Can communicate and be able to

In addition, when the writing of such a comment and the reproduction of the moving image from the time when the comment is written are repeated, the difference in reproduction timing of the moving image approaches 0 between the users, and the same moving image is substantially the same timing. While browsing, you can exchange comments.

Here, the case where a plurality of users browse the same video has been described, but for a certain video, if a user reproduces a video while no one is watching it, the memory is stored so far The comment information that has been transmitted is distributed from the comment distribution server 2 to the terminal device 3 and sequentially reproduced according to the timing of moving image reproduction. As a result, even if there is no user who is viewing by anyone else, comments commented in the past can be viewed in order according to the movie playback time of the movie. You can also write a comment here.

In the embodiment described above, when a comment is added to the comment list and the added comment is clicked by the user, it is reproduced from the moving image reproduction time that matches the comment provision time set in the comment, Although the case where a comment is displayed has been described, if the added comment is not clicked, the comment will be displayed on the video when the video playback time reaches the comment addition time set in the added comment. Is displayed.
Also, even if comments are written by other users at the video playback time of the video you are viewing, they will be displayed in the comment list in real time order, so click on the added comment According to, the comment can be browsed by rewinding or fast-forwarding when the comment is written. Also, here, the video playback time is rewound, so that the comments written up to that time including the newly added comment are sequentially displayed according to the video playback time according to the comment application time. Be done.

Here, it is also 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 with this operation, the moving image is rewinded or fast-forwarded. It may be difficult to find the comment you want to see immediately on the screen and it may be difficult to find it, but it is also possible to see from the scene you want to see by selecting it from the comment list.
Moreover, in the embodiment described above, the case has been described where the terminal device 3 receives the comment data distributed from the comment distribution server 2 and reflects it on the screen to display, but in the terminal device 3 of its own, input from the user The comment may be displayed on the screen as soon as the comment is input (before it is 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 moves to step S210, and the input comment is added to the comment list and saved, and
It may be transmitted to the comment distribution server 2.

Next, the display of the comment will be described.
The input comment can be set by inputting the display position such as the upper stage, middle stage or lower stage on the screen or the display time for moving and displaying the comment in the input field 109. Further, in the case of setting the display time, for example, the comment can be displayed for a predetermined time (for example, 4 seconds) in the upper part of the screen and erased. In addition, it is also possible to adjust the moving speed by designating a time (for example, 4 seconds) from the appearance in the display area of the screen to the movement out of the area. Also, if a large number of comments are input intensively at a certain moving image playback time, etc., if they overlap with a line of the same height when they are displayed, the height on the screen is changed and displayed or moved It is possible to display. In addition, if the moving speed differs depending on the length of the comment character string because the display time is set, the next comment may catch up before the comment is moved, so Also in the case, the next comment may be displayed or moved on a line of a different height.

In addition to inputting text, 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 depiction or a real image by unchecking the “one line” of 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 lines of the ASCII art fit within the screen.

Also, the old and new of the comment may be determined based on the real time, and the comment input at the old time in real time may be displayed semi-transparently after a predetermined time is displayed, and then deleted. Also, the importance may be set to 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 comment of the route 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 degree of importance. For example, comments with a high degree of importance may be displayed on the line at the top of the screen, and comments with a low degree of importance may be displayed on the line at the bottom of the screen.

In the embodiment described above, although the case where the moving image distribution server 1 and the comment distribution server 2 are different servers has been described, the functions of the moving image distribution server 1 and the comment distribution server 2 are realized by the same server. You may do so.
In the embodiment described above, when viewing comments and videos in the service, the comment distribution server 2 is accessed to receive data of a recent comment list,
Although the case of selecting a moving image and a thread from the recent comment list displayed on the display device 34 has been described, this moving image can be specified as a thread, a URL for viewing comments and moving images can be created and published on the Internet You may Specifically, a video ID and a thread ID are included, and when you click, a URL that can play back the video and receive comment information on that thread is written to a blog or a bulletin board on the Internet site, and so on. You may make the user click. In addition, such a URL may be set as a thumbnail image or the like and may be clicked.

In addition, on such a recent comment list, thumbnail images are displayed on the right or lower side of the screen (for example, FIG. 5) on which a moving image and comments are being viewed, or a thread with a large number of accesses is displayed. It may be displayed as a ranking, and the user may click to display the thread set for the clicked thumbnail image.

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

Also, for the comment list, the comment was displayed once on the video, or
About what the user clicked and browsed in the comment list, in the comment list, it may be possible to specify that it has been browsed. For example, change the text color,
You may make it display the mark which shows having been browsed.

Alternatively, an individual user identifier may be assigned to each user, and for example, a comment may be associated with the user identifier to be comment data. This makes it possible to identify who said a comment. Furthermore, comments may be displayed in different character colors according to the user identifier. This makes it possible to identify the user who spoke.
In addition, by allocating a user ID to the user who has accessed the system in advance and storing the user ID in the comment data, the comments uttered by each user may be displayed as a list by pop-up display, for example. . Note that this user ID is
Each user may be assigned by prior user registration, or information for identifying a terminal device may be used. In the case of using the information specifying the terminal device, for example, calculation may be performed by a hash function based on the information 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, the case of deleting a posted comment will be described. The deletion of the comment here is made such that the comment to be deleted is not displayed on the screen, for example, in response to a comment deletion instruction from a user who has the authority to delete the comment input via the terminal device 3 be able to. Also, even for a user who does not directly have the right to delete a comment, according to the number of requests to delete a comment from a user who does not have that right, to make the comment translucent or not to display the comment. Is possible.

Hereinafter, the comment delivery system in the second embodiment will be described.
FIG. 11 is a schematic block diagram showing the function of the comment delivery system in the second embodiment. In this figure, parts corresponding to the parts in FIG. 2 are given the same reference numerals and descriptions thereof will be omitted. In this embodiment, it is assumed that a comment ID is assigned to each comment of the comment information.
The communication unit 241 further receives comment deletion request information transmitted from the terminal device 3 in addition to the function of the communication unit 24 in FIG. 2. The comment deletion request information here includes a comment ID to be deleted, a thread ID specifying a thread in which the comment to be deleted is registered, a moving image ID specifying a moving image corresponding to the thread, and deletion. And an erase request user ID for identifying the user who made the request.

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 moving image ID, the thread ID, and the deletion request user ID included in the comment deletion request information. To determine if you have the right to The authority determining unit 231 stores an authority table for determining whether or not the user has the authority in the internal memory area of the self, and refers to the table to determine whether or not the user has the authority. An example of this authority table is shown in FIG. As shown in FIG. 12, in the authority table, the video ID is
, And a thread ID, and a user ID having a deletion right for identifying a user who is authorized to delete a comment registered in the thread ID is stored in association with each other. In this case, only one erasing right possessing user ID may be stored for one combination of the moving image ID and the thread ID, and a plurality of erasing right possessing user IDs may be stored. The authority judging unit 231 refers to this authority table and judges whether or not the combination of the video ID and the comment ID included in the comment deletion request information is present in the authority table, and if there is a video ID and a comment ID, further. Then, it is judged whether or not the deletion right owner user ID associated with the comment ID of the right table matches the user ID included in the comment deletion request information, and is included in the deletion right owner user ID and the comment deletion request information. If the user ID matches, it is determined that the user has the right 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 that the authority determination unit 231 does not have the erasure authority.
The display database 234 associates and stores the count number and the display method. An example of the 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, 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 comment that is semi-transparent to a moving image, and “transparent” corresponding to deletion of a comment are set.

The display selection unit 233 reads the display method corresponding to the count result (n) counted by the erasure request count unit 232 with reference to the display database 234, adds 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 above-described second embodiment will be described.
FIG. 14 is a sequence diagram for explaining the operation of the comment delivery system in the second embodiment.
First, as described in the first embodiment, the comment distribution server 1 collects comments posted from the terminal device 3 and distributes them as comment information to each terminal device 3 to display moving images and comments 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 mouse etc. and clicks the deletion request button displayed on the screen, the terminal device 3 reads out the comment ID, the moving image ID and the thread ID of the clicked comment from the comment information storage unit 33, and reads the read comment I
The D, the moving image ID, the thread ID, and the user ID of the user using the terminal device 3 of their own are associated, and are transmitted to the comment distribution server 1 as a comment deletion request (step S3).
01).

When receiving the comment deletion request information from the terminal device 3 (step S401), the comment distribution server 1 is authorized whether the user ID included in the received comment deletion request information has the authority to delete the comment. The determination unit 231 makes a determination (step S40
2). As a result of the determination, if the user has the deletion right, 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.
In the “comment display method” of the comment information stored in the comment information storage unit 21 that matches the moving image ID, the thread ID, and the comment ID included in the received comment deletion request information,
Write information indicating "do not display".

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, for deleted comments,
Although the comment data is stored, it is not displayed on the screen, and a comment not to be deleted 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 23
2 detects as comment deletion request information from a user who does not have this deletion right. Then, the deletion request counting unit 232 counts up the deletion request of the comment ID of the moving image ID and the thread ID included in the comment deletion request information (step S405), temporarily stores it in its own internal counter, and counts the count. 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 based on the count result output from the deletion request count unit 232 (step S406).
The "comment display method" of the comment information storage unit 21 is written according to the read display method according to the moving image ID, thread ID and comment ID.

When the comment display method is written in the comment information storage unit 21, the comment information distribution unit 2
2 transmits the comment information after the comment display method is written to the terminal device 3 (step S404). As a result, in accordance with the transmitted comment information, the message is displayed on the terminal device 3 (step S302).

According to this embodiment, the comment is deleted according to the presence or absence of the authority. As a result, whether the comment is inappropriate for the thread, the manager of the thread, etc.
Comments can be displayed in consideration of the intention of the user having special authority. In addition, even a user who does not have the right to delete a comment only by his own intention can delete the comment or display different from other comments such as semi-transparent depending on the number of the user. . In this way, comments can be written and deleted among a plurality of users, and the amusement of the thread can be improved.

In the second embodiment described above, the case where the erasure request counting 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, but the authority determination unit 231 erases Only one of the request counting units 232 may be provided in the comment information update managing unit 23. That is, the deletion request may be accepted only from the user having the deletion authority, and the comment may be deleted. Also, regardless of the presence or absence of the deletion authority for the comment, the number is received according to the number of deletion requests received from the user. The comment may not be displayed or may be translucent.

Also, in the second embodiment described above, the comment display method is “normal”, “semi-transparent”,
Although the case of "transparent" has been described, it is sufficient if the comment to be deleted can be displayed differently to the normal comment, for example, by setting the level of translucency in multiple stages, changing the color of the comment, In addition, the character size, the font of the character, the gradation of the color may be changed or the white may be removed.
Alternatively, the user having the authority to delete the comment may receive an input for a cancellation request for deleting the comment, and the deleted comment may be displayed according to the instruction.
