A determination unit for determining whether or not a comment displayed by the display unit overlaps another comment; and Part is when it is determined that the overlap comments and characterized by having a display position control unit for displaying a comment for readable display of the comment.

  Further, according to the present invention, in the display device described above, the comment display unit is configured to display the comment during the comment display time based on the comment display time that is the time to be displayed and the character string length of the comment. Is displayed on the screen, and the determination unit determines whether or not comments overlap based on the comment display time of the comment and the character string length of the comment.

In the display device described above, the present invention is characterized in that the determination unit determines whether or not comments displayed at fixed positions overlap each other.
In the display device described above, the comment display unit moves the comment at a moving speed based on the comment display time that is the time to be displayed and the character string length of the comment. Display is performed on the screen, and the determination unit determines whether or not the moving comment and another moving comment overlap based on the comment display time of the comment and the character string length of the comment. It is characterized by that.

  In the display device described above, the determination unit may determine whether or not the comment displayed by movement overlaps with the comment displayed at a fixed position. When the comment displayed at the fixed position continues to overlap during the fixed display, it is determined that the comment is overlapped. In some cases, it is determined that they do not overlap.

  In the display device described above, the comment display unit may include a character size changing unit that changes and displays the character size of the character string, and the determination unit is changed by the character size changing unit. The character string length is determined based on the character size after the determination, and it is determined whether or not comments overlap.

  Further, according to the present invention, in the above-described display device, the comment display unit displays a comment in a plurality of lines, and the determination unit determines whether or not they overlap based on the number of comment lines and the character string length of each line. It is characterized by determining.

  In the display device described above, the present invention further includes a receiving unit that receives comment information from a comment distribution server that distributes comment information, and the comment display unit receives the moving image from the comment information received by the receiving unit.

In the input field 108, the name of the user who speaks for the moving image is input via an input device such as a keyboard. In the input field 109, the mail address of the user who writes the comment is input. In addition to inputting an e-mail address, the input field 109 can also input information specifying how to display a comment. As the way to display the comment, for example, the position to be displayed on the comment video, font, character size, start position and end position to move display, direction to move display, etc. are specified for overlay display. It can be set as information to be performed.

  A comment is input to the comment field 110 by the user via the input unit 37. When the button 111 is clicked, the comment input in the display field 110 is transmitted to the comment distribution server 2. The display column 112 is an area in which a comment list that is a list of comments is displayed. The comment list includes a number indicating the order of comments given to the comment (reference numeral 112a), the name of the user who input the comment (reference numeral 112b), the comment addition time when the comment was written (reference numeral 112c), and the commented comment. Is displayed according to the order of the posted real-time information. The display field 112 is provided with an input field such as a check box for designating whether or not the display field 112 is displayed on the screen, and the display field 112 is displayed or displayed according to the display permission instruction input to the input field.

  The check box 114 designates a comment input to the comment field 110 as one line by inputting a check mark. For example, if a check mark is entered in the check box 114 and the input of the comment is completed, and the input is completed by pressing the enter key, for example, the “write” button is clicked when the enter key is pressed. As a result, the comment is transmitted to the comment distribution server 2. Thereby, it is possible to input a comment quickly and easily.

  Next, returning to FIG. 4, the input unit 37 is an input device such as a mouse or a keyboard, and receives input of various types of information from the user. The selection unit 38 receives an input for selecting a comment input via the input unit 37 from the list of comments displayed by the second display unit 36. The reproduction control unit 39 reads the comment data of the comment selected by the selection unit 38 from the comment information storage unit 33, and the moving image is reproduced by the first display unit from the moving image reproduction time corresponding to the comment adding time of the read comment data. While being reproduced and displayed on the display device 34, the comment content of the read comment data is displayed on the display device 34 by the first display unit 35.

  The transmission unit 40 receives data input of comment content for the video displayed by the first display unit 35 and transmits the video playback time at the time when the comment content is input to the comment distribution server as comment addition time together with the comment content. 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 thread ID of the comment information included in the distribution request is output to the comment information distribution unit 22. The comment information distribution unit 22 reads the comment information corresponding to the thread ID output from the communication unit 24 from the comment information storage unit 21 (step S102), and distributes the read comment information to the terminal device 3 that has requested the distribution ( Step S103). Here, each piece of comment information associated with the thread ID is transmitted in a batch.

  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 the terminal device 3 in which the session is valid can be specified as a moving image browsing.

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. 6 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, a second embodiment will be described. Here, a case will be described in which whether or not the position where the comment is displayed overlaps is detected and the display position of the comment is changed when it is determined that the comment is overlapped.
FIG. 11 is a block diagram showing a configuration of the first display unit 35 in FIG.
The changing unit 50 has a function of changing the character size of the character string to display it, or changing the font of the character and the decoration of the character (such as italic).
The determination unit 51 determines whether the displayed comment overlaps with another comment.
The determination unit 51 determines whether or not the comments overlap based on the comment display time of the comment and the character string length of the comment. Here, if the comments are comments displayed at the same position (fixed position), it is determined whether or not they overlap at the same coordinates at the fixed position. It is determined whether or not the comment is overlapped at the position displayed while moving.
Since the determination unit 51 moves and displays a comment, the comment is moved and displayed on the screen at a moving speed based on the comment display time that is the time to be displayed and the character string length of the comment. Based on the comment display time of the comment and the character string length of the comment, it is determined whether or not the comment to be moved overlaps with another comment to be moved.
The determination unit 51 also has a function of determining whether or not the comment displayed after moving and the comment displayed at the fixed position overlap with each other. If the comments displayed in are continuously overlapped during fixed display, it is determined that they are overlapping, and if there are periods that overlap even in some periods, they are determined not to overlap. .
Further, the determination unit 51 determines the character string length based on the character size after being changed by the changing unit 50, determines whether or not the comments overlap, or when the comments are displayed in a plurality of lines. It has a function of determining whether or not they overlap based on the number of comment lines and the character string length of each line.
When the determination unit 51 determines that comments overlap, the display position control unit 52 displays each comment so that it can be read. Here, the display position is changed so that the comment is displayed at a position where the comments do not overlap.

Next, the operation of the first display unit 35 in the configuration of FIG. 11 will be described. FIG. 12 is a flowchart for explaining the operation of the first display unit 35 in the configuration of FIG.
First, the changing unit 50 changes the shape of the character according to the character size, font, decoration (such as italic) among the display methods set in the comment. When the character shape is changed, the determination unit 51 determines whether or not the comments overlap each other.
Here, of the two comments to be subject to duplication determination, t1 indicates the end of the display of the first displayed comment (hereinafter referred to as the first comment), and the comment (hereinafter referred to as the second comment) displayed later. The display start time is set to t2 (step S301).
Next, it is determined whether the first comment and the second comment overlap at t1 (step S302). Next, it is determined whether or not the first comment and the second comment overlap (step S303).

  If the determination result in step S302 does not overlap (no comment overlap at t1) and the determination result in step S303 does not overlap (no comment overlap at t2), a comment It is determined that there is no need to change the display position, and the comment is displayed according to the display position set as the display method in the comment (step S305).

  On the other hand, in the determination result in step S302, if either one of the determination result in step S302 and the determination result in step S303 is a determination result that overlaps, or if the determination result is overlap in both The unit 51 determines that the comment display position is changed. If it is determined that the display position is to be changed, the display position control unit 52 changes the display position of the second comment. Here, for example, the display position of the second comment is changed to a preset relative position (lower or upper in the vertical direction of the screen with reference to the first comment). The preset relative position may be designated by the user when inputting a comment, or may be set in the display position control unit 52 in the terminal device 3.

Here, the duplication of comments will be further described. FIG. 13 is a conceptual diagram for explaining the duplication of comments. FIG. 13 is a diagram illustrating how the comment moves with time at a horizontal position of the screen on which the comment is displayed (screen width of the display screen). Here, the comment is moved and displayed from the right side to the left side toward the screen, the horizontal axis is the horizontal position of the screen, the vertical axis is the time axis t, and the downward direction is positive (the passage of time). is there. The width of the parallelogram shape corresponds to the width of the character string. Further, the description will be made assuming that the comment is displayed on the screen for 4 seconds.
First, in FIG. 13A, the display position is not changed because the first comment and the second comment do not overlap at t1 and t2.
On the other hand, in FIG. 13B, the first comment and the second comment overlap at both t1 and t2. Therefore, in this case, the display position of the second comment is changed.
In this way, overlap determination and display position change are performed.

  Note that the determination unit 51 determines that one of the first comment and the second comment is a comment that is displayed at a fixed position and the other is a comment that is displayed while moving. Also good. In this case, it is determined whether or not there is a period in which the first comment and the second comment overlap while being displayed at the same height on the screen. If there is an overlapping period, the display position is changed. . Even if there is an overlap period, if the overlap time is within a predetermined time period, or the ratio of the overlapping comment area and the non-overlapping area is determined in advance. If it is less than or equal to the specified value, it may not overlap. In addition, you may make it perform duplication determination about the comments displayed at a fixed position. In this case as well, even if there is an overlap period, if the time during the overlap is within a predetermined time, or the ratio of the area that does not overlap with the overlapping comment area May be non-overlapping when is less than or equal to a predetermined value.

  In the embodiment described above, the comment is moved and displayed from the right side to the left side of the screen with the upper end of the area for displaying the comment as a reference position. The display position is changed downward from the upper end, which is the reference position, by the vertical width of the size of its own comment. The vertical width is determined by the font size of a single-line comment, and is determined by the font size and the number of lines of a multi-line comment. Then, the duplication determination of the comment is performed again at the changed display position. If there is no duplication, the position is set as the vertical position (height) for displaying the comment. If it is determined that the display position after the change is duplicated, the display position is changed downward by the width of the size of its own comment. Repeat the process. Here, the reference position is the upper end of the comment display area, but the display position may be changed upward with the lower end as a reference. The comment display position is changed by the vertical width of the comment size. However, the display position is changed within the range of the vertical size of the comment size (for example, half or one third). You may do it.

  In the embodiment described above, the display position control unit 52 changes the display position upward or downward by the vertical width of the comment size when the comment overlaps. The display position control unit 52 may be used as a display control unit, and each comment may be displayed readable by the display control unit. For example, you may make it change the color shade which displays one of the overlapping comments. Specifically, when starting to display the comment that will be displayed later among the overlapping comments, the display color of the comment displayed earlier is lightened so that both comments can be displayed in a legible manner. Good. In addition to changing the shade of the color for displaying the comment, each comment may be displayed in a different color, and the boundary of the overlapping portion may be displayed in a color different from each comment.

According to the embodiment described above, it is determined whether or not the display positions of the comments are overlapped, and if they are overlapped, even if a plurality of comments are displayed by changing the display position to a position that does not overlap, It becomes possible to prevent the reading from becoming difficult.
Even if the added comment information is distributed from the comment distribution server 2 to the terminal device 3 and the added comment information is newly received and displayed in accordance with the video being played back, As described above, the duplication determination is performed and the display position of the comment is controlled.

  In the above-described embodiment, the comment input by the user can be set by inputting the display position such as the upper, middle, and lower stages on the screen and the display time for moving and displaying the comment in the input field 109. It is. 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.

  Further, in the above-described embodiment, the case where the thread ID is specified 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 specified, the representative thread is displayed. Also good. 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.

  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. A program for realizing the functions of the reception 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, and the transmission unit 40, or the change unit in FIG. 50. A program for realizing the functions of the determination unit 51 and the display position control unit 52 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed. Comment distribution and 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.
