Abstract

PROBLEM TO BE SOLVED: To solve the problem that, in a motion picture viewing system for displaying a comment created by a user on a network simultaneously with a motion picture, the comment is frequently displayed while being moved but this may not harmonize the comment and the motion picture and further, in a low-spec terminal, an image processing capability is limited for the mobile display of the comment.SOLUTION: A motion picture viewing system comprises a stationary comment distribution server and a motion picture distribution server. The stationary comment distribution server distributes a comment viewing a motion picture or transmitted from a terminal where the motion picture is viewed, in response to reproduction of the motion picture so as to display the comment as a stationary comment substantially in the same timing as timing in which the comment is transmitted to the terminal which is reproducing the motion picture. The stationary comment distribution server includes a comment arrangement information transmission section for transmitting comment arrangement information in order to calculate a comment arrangement schedule, the comment arrangement information including continuous display time information indicating a time length from display of each comment to erasure and screen occupancy amount information indicating a screen occupancy amount of each comment.

Description

  The present invention distributes a video viewing system for displaying comments in conjunction with a video, an operation method of the system, a video playback terminal device capable of viewing video in the system, an operation program and an operation program of the device Regarding the server.

  Conventionally, in a service for distributing moving images from a moving image distribution server to an unspecified number of moving image playback terminal devices, comments arbitrarily written by a plurality of users can be displayed in conjunction with the moving images. A video viewing system is provided. With this technology, for example, comments such as comments and criticisms in a scene of a movie can be displayed in conjunction with the scene. As a result, the user who wrote the comment and the user who saw the comment display It is possible to provide a video experience with communication via video or comments.

  Here, as a display form of the comment, those using various methods are already known. Specifically, for example, a technique related to a control method for avoiding a situation in which a plurality of comments are displayed and are difficult to see due to a plurality of comments being written at substantially the same timing, and for general users such as slander slander There are known techniques for limiting the display of comments that are inappropriate to be displayed. Patent Document 1 discloses a technique for avoiding a situation in which a plurality of comments overlap with other comments and cannot be read.

  In the technical field, a technique for moving and displaying comments is known as a technique for realizing various video experiences by many users. In other words, it is possible to consider elements such as “movement” and “speed” as elements of comment display by performing display that moves the comment at a predetermined speed, and broaden the range of expression. Is possible. In addition, when a plurality of comments are moved and displayed at a predetermined timing, the amount of dynamic information increases dramatically compared to the case of displaying only a video, so the display screen becomes lively. It is also possible to evaluate as a barometer of the degree of “swell” of the user.

JP 2008-148071 A

  However, although the movement display of these comments has a certain meaning as an expression method of “swell” as described above, there are cases in which harmony with the originally displayed video is not successful by adding movement information. is there. In such a case, there may be a situation where the user's fundamental purpose of “enjoying watching a movie” is neglected. Furthermore, since the low-spec video playback terminal device has a limit on the image processing capability of the terminal, there has been a situation in which comments are not smoothly moved and displayed, and the display of the entire video is not stressless.

  In order to solve the problems as described above, the present invention provides a video distribution server that distributes a video, and a comment that is viewed from or received from a video playback terminal device that has watched or viewed the video. The comment to be played back at a predetermined timing is displayed at substantially the same timing as the timing at which the comment should be displayed on the video playback terminal device receiving and playing back the video from the video delivery server as a still comment. A moving image viewing system comprising a distributed still comment distribution server, wherein the still comment distribution server is a reproduction time timing that is a timing at which each comment is started to be reproduced in a moving image reproduction screen and / or a timing at which the comment is subsequently erased The continuous display time information, which is information indicating the erase time timing, and the comment assigned to each comment A comment arrangement information transmitting unit for transmitting comment arrangement information including screen occupation information indicating a screen occupation amount in order to calculate a comment arrangement plan simultaneously displayed on the video playback screen in the video playback terminal device; We propose a video viewing system.

  In addition, a moving image receiving unit that receives a moving image from the moving image distribution server, the character information of the still comment from the still comment distribution server, the continuous display time information of the comment configured by the character information, and the character information A comment placement information receiving unit that receives the comment placement plan information, and a comment placement plan calculation unit that calculates a comment placement plan from the received comment character information and the received comment placement information. A video playback terminal device having a playback unit that plays back a comment simultaneously with a video based on the comment arrangement plan is also proposed.

  In addition, an operation program distribution server that distributes the operation program of the moving image playback terminal device is also proposed.

  With the present invention mainly configured as described above, the degree of excitement by each user is dynamically expressed using comments without being influenced by the specifications of the terminal and without excessively hindering the viewing of moving images. It becomes possible to do.

<< Embodiment 1 >>
<Overview>

FIG. 1 is a conceptual diagram of the moving image viewing system of the present embodiment. As shown in the figure, the video viewing system according to the present embodiment includes a “video distribution server” 0110 that distributes video and comments received from the video playback terminal device that viewed or watched the video. The comment to be played back at a predetermined timing with respect to the playback of the video is abbreviated as the timing at which the comment should be displayed on the video playback terminal device that receives and plays back the video from the video distribution server as a still comment. A “still comment distribution server” 0120 that distributes the images so that they are displayed at the same timing. The still comment distribution server receives comment arrangement information including continuous display time information and screen occupancy information as a video playback terminal. Transmitting to calculate the arrangement plan of comments simultaneously displayed on the video playback screen in the device
<Functional configuration>

  FIG. 2 is a diagram illustrating an example of functional blocks of the moving image viewing system according to the present embodiment. As shown in this figure, the moving image viewing system of the present embodiment includes a “moving image distribution server” 0210 and a “still comment distribution server” 0220, and has a “comment arrangement information transmission unit” 0221 in the stationary comment distribution server. .

  Note that the functional blocks of each device constituting the moving image viewing system described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a GPU, an image memory, a graphic board, a bus, or a secondary storage device (a storage medium such as a hard disk, a nonvolatile memory, a CD, a DVD, and the like) Media reading drives, etc., input devices used for information input, displays, printers, and other hardware components such as external peripheral devices, and interfaces for external peripheral devices, communication interfaces, and control of these hardware For example, a driver program and other application programs. Then, by the arithmetic processing of the CPU in accordance with the program developed on the main memory, the data input from the input device or other interface etc. and held in the memory or hardware is processed and accumulated, or each of the hardware And commands for controlling the software are generated. Here, the program may be realized as a plurality of modularized programs, or may be realized as a single program by combining two or more programs.

  The present invention can be realized as a system in combination with one or a plurality of apparatuses, and can be realized as a method. A part of such an apparatus can be configured as software. Furthermore, a recording medium on which such software is recorded is naturally included in the technical scope of the present invention. In addition, an apparatus for transmitting the software to a client via a network is naturally included in the technical scope of the present invention (the same applies throughout the present specification, not limited to the present embodiment). .)

  The “moving image distribution server” 0210 has a function for distributing moving images. As a specific configuration that can be considered, one or a plurality of “moving image information” 0211 is stored and accumulated, and when a distribution request for a specific moving image is received from the moving image playback terminal device, the moving image information that is a request target May be configured to fulfill the distribution function by transmitting to the video playback terminal device. The distribution form here is usually streaming distribution, but may be download distribution. It should be noted that individual moving image information can be preliminarily provided with distribution restriction information including contents that should restrict the viewing or distribution of moving images, such as the viewable age and the number of viewable times. When a distribution request for a video with the information is received, for example, the user ID associated with the video playback terminal device that transmitted the distribution request is compared with the distribution restriction information to determine whether the distribution is appropriate or not. It is also possible to adopt a configuration for judging. By adopting such a configuration, for example, it is possible to avoid a situation in which a minor with insufficient judgment ability sees an excessively violent and cruel depiction of a moving image.

  “Still comment distribution server” 0220 is a comment character information and comment arrangement information (hereinafter referred to as at least these two pieces of information) that define the character, symbol, font, color, etc. of one or more comments transmitted from each video playback terminal device. "Comment display information") is abbreviated as the timing at which a comment should be displayed on a video playback terminal device that receives and plays back a video from the video distribution server as a static comment. It has a function for delivering so as to display at the same timing. Since the comment displayed in the present embodiment is a “still comment” that does not display any comment other than display / non-display, a process for moving and displaying the comment becomes unnecessary, and a low-spec terminal It is possible to display comments without any particular stress.

  Incidentally, the comment is distributed from the stationary comment distribution server, but this does not necessarily mean that the comment display information is generated by the stationary comment distribution server. That is, the comment display information may be generated / held and distributed by the static comment distribution server as shown in FIG. 1, or may be generated / held by another mechanism. May be transmitted to the still comment distribution server through the network in response to the transmission request, and further to the moving image playback terminal device.

  Below, each information which comprises comment display information is demonstrated. First, as an example of a method for creating and transmitting comment character information, each video playback terminal device creates text information for the comment at the timing of a scene in which a comment is desired to be displayed during video playback. It is possible to adopt a method of transmitting to On the other hand, a method of creating character information of a comment by designating a predetermined reproduction time timing of a moving image once viewed may be adopted. A comment to be displayed is created from the character information of the one or more comments transmitted in this way. Accordingly, the comment placement information distributed from the stationary comment distribution server is not always information regarding the display of one comment, but is sometimes positioned as information regarding the mutual display of character information of a plurality of comments created by a plurality of users. .

  Next, comment arrangement information will be described. “Comment arrangement information” is information for controlling the display of comments in the video playback terminal device, and is composed of screen occupancy information, continuous display time information, and other information described later. Using the information, an arrangement plan for displaying the comment simultaneously with the moving image on the moving image reproduction screen is calculated by the moving image reproduction terminal device.

  FIG. 16 is a diagram showing a specific example of processing in creating comment placement information in the present embodiment. In the figure, for a certain video, as shown in FIG. 1, different video playback terminal devices A to E create seven comments a1 to e that are displayed at a predetermined playback time timing of the video. It shows how they are doing. For example, as shown in FIG. 16, the video playback terminal device C is displayed at 09:23:38 on May 1, 2012 at the timing of the playback time of the target video 0 minutes 37 seconds. A 6-character comment c is created. Also, the video playback terminal device D creates a four-character comment d that is displayed on February 3, 2013 at 06:08:40, at the timing of the target video playback time of 0:37:50. ing. The comment arrangement information is information that regulates in what arrangement the character information of each comment should be displayed in what time zone and in what mode.

  “Continuous display time information” 0223 is information indicating a reproduction time timing that is a timing at which each comment is started to be reproduced in the moving image reproduction screen and / or an erase time timing that is a timing at which the comment is subsequently erased. By grasping the timing to start comment display, it is possible to display comments in a pinpoint with respect to the predetermined playback timing of the video, and further by grasping the timing when the comment should be deleted, It is also possible to grasp the length of time for which comments should be displayed continuously. As will be described later with reference to FIG. 17, it is not always necessary to uniformly determine the length of time when the comment display is continued. For example, information indicating the display time corresponding to the number of characters may be used. Good. Therefore, when the display time corresponding to the number of characters is set, the information on the number of characters is also included in the continuous display time information here.

  The length of time for which the display of the comment should be continued is an arbitrary design matter, but because the comment has the property of being attached to the predetermined playback time timing of the video If you continue to display comments for an excessively long time, there is a possibility of discrepancies with the playback content of the movie. Although it depends on the content of the moving image and the playback time, in FIG. 17, the length of time for which the comment display is continued is set to 4 seconds.

  The continuous display time information does not regulate the display mode of the comment at the timing. Therefore, there is no particular problem even if the display mode control information for regulating the display mode is configured as a part of the comment arrangement information when the display of the comment is to be continued. As specific contents of the display mode control, the comment may be continuously displayed during the time when the comment should be continuously displayed, and display and non-display are repeated at a predetermined timing during the time. A display form in which comments are blinking may be realized. Further, it may be possible to adopt a display form in which the comment fades out or fades in by changing the display density of the comment as the display time elapses. It is possible to emphasize the comment by blinking display, and it is possible to adopt various display forms such as giving a soft impression to the comment by performing fade-in or fade-out display. Thus, various expressions related to comments can be made within a limited display time.

  “Screen occupation amount information” 0222 is information indicating the screen occupation amount allocated to each comment. The screen occupancy here is positioned as information indicating how much screen area is occupied as a whole comment as well as characters or symbols constituting the comment. Therefore, the screen occupancy information is determined, for example, by grasping the entire comment including the space (gap) between each character / symbol as one area, and the font size of each character and each symbol constituting the comment. It may be determined paying attention to. In FIG. 15 described later, the number of comment characters is used as screen occupation amount information. The moving image viewing system of the present embodiment is characterized in that comments are displayed in the form of a static comment instead of a moving format, and the comment can display all the constituent characters from the start to the end of the display. A certain area needs to be secured. Under such a premise, by adopting a configuration for grasping the screen occupancy, it is possible to display still comments appropriately.

  Here, FIG. 15 is a diagram illustrating a specific example of processing for calculating a comment arrangement plan using screen occupation amount information. In the following description using the figure, it is assumed that comments are written horizontally, and an area occupied by a predetermined standard font size of 30 characters on the screen is an area where comments can be displayed per comment. Here, for example, if the number of characters of a comment to be displayed is within 7 characters, display is performed so as to secure a screen occupation amount corresponding to the standard font size of 10 characters. Similarly, if it is 8 characters or more and 15 characters or less, it displays so as to secure the screen occupation amount for 15 characters, if it is 16 characters or more and 22 characters or less, 20 characters, if it is 23 characters or more, 30 characters Display to ensure the screen occupancy of the minute. Further, when a plurality of comments to be displayed within a predetermined timing are less than a predetermined screen occupancy (for example, screen occupancy for 5 characters), each comment is not divided into a plurality of lines. It is also conceivable to perform calculations that display them side by side in a single row. When a plurality of comments are displayed together on one line, the arrangement relationship of each comment in one line (such as whether each comment is displayed on the left or right) may be arbitrarily determined, but one comment per line. When only the comment is displayed, it is desirable that the display be arranged at the center of the line as much as possible.

  Note that the duration display information and the screen occupancy information described so far are both used as comment arrangement information to calculate the arrangement plan of comments displayed simultaneously on the video playback screen in the video playback terminal device. Information. The “arrangement plan of comments simultaneously displayed on the video playback screen in the video playback terminal device” is, for example, a video playback terminal device that creates a plurality of comments when there are a plurality of comments to be displayed at a predetermined timing. The calculation is performed paying attention to the ID. Specifically, each comment is sequentially moved from the upper part of the video playback screen to the lower part of the video playback terminal device ID that created the comment, in the order from the lowest number, the ID acquisition date and time, or from the earliest comment creation date and / or The content is to display from the bottom to the top. Further, as shown in the screen display in FIGS. 3 and 18B, 18C, and 18D, depending on the number of characters, a plurality of comments may be displayed together on one line, or simply a plurality of comments may be displayed. The layout plan may be calculated in such a manner that the characters are sequentially displayed from the upper part to the lower part and / or from the lower part to the upper part in order of increasing or decreasing the number of characters. More specifically, when the screen occupancy of the comment to be preferentially displayed is less than the amount that can be displayed in one line, another display that satisfies the displayable occupancy should be displayed. You can plan to display comments on the same line. In this case, the comment to be displayed next is sequentially displayed on the upper or / and lower line.

  In FIG. 16, the video playback terminal device that created the comment displays the video playback terminal device ID, the comment creation date and time, and the number of characters of the comment in association with the comment. Is used to calculate the arrangement plan of each comment.

  Incidentally, as the comment arrangement information, in addition to the continuous display time information and the screen occupation amount information, various kinds of information related to the arrangement of the comments when the comment is displayed on the video playback terminal device may be included. For example, basic comment display area setting information for specifying a basic comment arrangement area that is an area for comment arrangement in principle on the screen, or the basic comment arrangement area is displayed so that it can be distinguished from other display areas (for example, , Change the background color only in the area, always display during video playback, or display only the comment display area during comment display, etc.), the total number of comments, the total number of characters of all comments, etc. May be included.

  Here, as FIG. 17, a diagram showing an example of an arrangement plan calculated in the present embodiment is shown. In the drawing, the timing at which the display of each comment is to be started and the timing at which the display based on the continuous display time information is to be ended are indicated by arrows. By clarifying the timing for displaying each comment, it can be seen that there are multiple comments to be displayed at a certain point in time. In such a case, it is further determined how each comment should be arranged. It will be calculated in detail. In addition, the description of (a) thru | or (f) below each broken line of the same figure has shown the correspondence with FIG. 18 which shows the display mode of the moving image and comment in each reproduction time timing.

  “Displayed simultaneously from the upper part to the lower part of the moving image reproduction screen and / or from the lower part to the upper part” described as an example of the arrangement plan does not necessarily mean that the entire screen is the target of comment display. FIG. 3 is a diagram showing an example of a comment display in the video viewing system of the present embodiment. As shown in FIG. 3, for example, among the two areas displayed in the shaded area in FIG. A region extending from the uppermost part of the upper region 0310 to the lower part by a predetermined interval or / and a region extending from the lowermost part of the lower region 0320 to the upper part by a predetermined interval among the two regions is set as a region for displaying a comment. By adopting this configuration, an area where no comment is displayed appears at the center of the entire moving image playback screen. By displaying the comment without moving it, the video is hidden in the comment and is not displayed or difficult to see in the same display area while the comment is displayed. Since this is generally the central part, it is possible to avoid a situation in which the comment disturbs the display of the moving image itself by not displaying the comment in this area.

  On the other hand, when a predetermined condition is satisfied, it may be possible to deliberately display a comment in the center of the screen to aim for a certain visual effect. Specifically, even if an area for displaying a comment as described above is set, if a comment to be displayed simultaneously exceeds a predetermined threshold, the display is performed regardless of the setting. It is conceivable to adopt a configuration in which a comment is displayed even in an area that should not be. In this case, for a comment displayed exceeding the threshold value, the continuous display time may be shorter than the predetermined continuous display time. By adopting each of the configurations, comments are often displayed over the entire screen. By such display, it is possible to visually express the excitement of the specific part of the video by the users. It becomes possible.

  Here, FIG. 18 is a diagram illustrating an example of comment display performed using the moving image viewing system of the present embodiment. In the same figure, it is the figure which showed the display of the comment made | formed with respect to the moving image which a vehicle drive | worked in order of the order of the scene of (a) to (f) in time series. Described in the upper right column of each figure is the playback time of the scene in the moving image. As shown in the figure, the comment is displayed in the moving image display area at 0 minute 30 seconds after the start of reproduction of the moving image (by the way, display is started from 0 minute 29 seconds using FIG. 16). It is displayed at the top, and new comments are displayed over time, and the display of old comments disappears after a certain period of time. These comments are created based on comment character information created by multiple users on separate occasions, transmitted from the stationary comment distribution server to the video playback terminal device, and distributed from the stationary comment distribution server. The arrangement plan is calculated and displayed based on the arrangement information. In principle, each comment is displayed from the top to the bottom of the area where the comments are displayed in ascending order of the registration number of the user who created the comment. However, a plurality of comments with a small screen occupation amount of the comment are collectively displayed on one line. Of the comments in FIG. 5E, the font size of a plurality of “?” Is smaller than the font size of the character “Kirin www” at the top. This is because the screen occupancy corresponding to the number of characters in the comment is smaller than the screen occupancy corresponding to the actual number of characters, so that the result of the layout plan calculation based on the screen occupancy information described with reference to FIG. This is because the display was made with a size smaller than the standard font size.

  The “video playback terminal device” that receives a comment from the static comment distribution server does not indicate only the video playback terminal device that created the comment, but a terminal of another user who uses the video viewing system of this embodiment. Also included. That is, as shown in FIG. 1, the character information a1 and a2 of the comment created by the video playback terminal device A is not only the video playback terminal device but also the video playback terminal devices B to E and X, It can be transmitted as a comment to other video playback terminal devices. Here, if such a configuration is adopted, a situation in which a huge number of comments are transmitted for one movie may occur, and when all the comments are displayed indefinitely, the movie display screen is displayed with a comment display. There can be a situation of being filled. For this reason, not all of the comments created for the one video are displayed, but only the number of comments up to a predetermined number, such as the latest order of comment posting date and time, is displayed. It is desirable to have a configuration that is displayed only between users who satisfy certain conditions such as processing.

  The “comment arrangement information transmission unit” 0221 has a function of transmitting the comment arrangement information in order to cause the video playback terminal device to calculate a comment arrangement plan. In the video viewing system of the present embodiment, the comment placement information is calculated not by the static comment delivery server, but by the comment playback information as “send to calculate the comment placement plan”. This is a function of the terminal device. By adopting such a configuration, for example, it is possible to realize a free comment display for each user, such as performing control on the user side so as not to display a comment by a user who has an unfavorable personal relationship. By the way, when control is performed so as not to display a comment on the user side, display control is performed so that only the specific comment is not displayed at a timing when a predetermined comment is to be displayed based on the comment arrangement information. It will be.

In addition, the video, the comment, and the comment arrangement information may be configured to be transmitted to the video playback terminal device at different timings, or the display start timing is synchronized so that all the information is transmitted substantially simultaneously. It may be configured as follows. “Transmitted to the video playback terminal device at different timings” means, for example, that a video is downloaded by the video playback terminal device and comments and comment arrangement information are distributed when the video is played back. Alternatively, only the moving image and the comment may be downloaded, and the comment arrangement information may be distributed when the moving image is played back. In the case of reproducing a moving image by streaming distribution, a comment and comment arrangement information may be downloaded prior to the moving image reproduction, and a comment may be displayed in synchronization with the reproduction timing of the moving image. Here, the comment may be streamed together with the moving image.
<Specific configuration>

  FIG. 4 is a schematic diagram illustrating an example of a configuration when each functional configuration of the still comment distribution server configuring the moving image viewing system of the present embodiment is realized as hardware. Below, the operation of each hardware component will be described.

As shown in this figure, among the devices constituting the video viewing system, the static comment distribution server includes “CPU” 0401, “storage device (storage medium)” 0402, and “main” for executing various arithmetic processes. A “memory” 0403, an “output interface” 0404, an “input interface” 0405, and an “Internet communication interface” 0406, for example, a “display” 0407, a “printer” 0408, and a “keyboard” via the input / output interface "0409" and information is transmitted / received to / from an external peripheral device such as "Movie player terminal" 0410 via the Internet communication interface. The storage device stores various programs as described below, and the CPU reads these various programs into the work area of the main memory, and develops and executes them. These components are connected to each other via a data communication path such as “system bus” 0411 to transmit / receive information and process information.
(Specific processing in the static comment distribution server)

  The CPU reads out the comment information held in advance, executes the “comment distribution program” 0413, and performs processing for distributing the comment information to the video playback terminal device receiving and playing back the predetermined video. .

Further, the CPU executes the “comment arrangement information transmission program” 0414, reads the comment arrangement information associated with the comment distributed by the execution of the comment distribution program, and transmits the comment arrangement information to the video playback terminal device. Perform the process.
<Process flow>

  FIG. 5 is a diagram illustrating an example of a processing flow in the moving image viewing system of the present embodiment. The flow of processing in the figure consists of the following steps. First, in step S0501, a distribution request for a predetermined moving image and comment information associated with the moving image is received from the moving image playback terminal device (moving image / comment information request step).

  Thereafter, in step S0502, the moving image requested for distribution is distributed from the moving image distribution server to the moving image playback terminal device (moving image distribution step). In step S0503, a comment associated with the moving image requested for distribution is distributed to the moving image reproduction terminal device (comment distribution step). Further, in step S0504, continuous display time information is acquired as information indicating the length of time from when a comment is displayed on the video playback screen to when it is deleted (continuous display time information acquisition step). In step S0505, screen occupancy information occupying the screen occupancy allocated to the comment is acquired (screen occupancy information acquisition step). Here, step S0504 and step S0505 are not necessarily processed in the order shown in FIG. 5. For example, the process of step S0504 may be performed after the process of step S0505. In step S0506, comment arrangement information including at least continuous display time information and screen occupancy information is acquired (comment arrangement information acquisition step). In step S0507, the video is requested to be distributed or linked to the video. The comment arrangement information associated with the comment and including the continuous display time information and the screen occupation amount information is transmitted to the video playback terminal device (comment arrangement information transmission step).

Here, it is not essential that step S0502, step S0503, and step 0507 are processed in the order shown in FIG. For example, the process of step S0502 may be performed after the processes of step S0503 and step S0507. Therefore, step S0506 or step S0504 and step S0505 which are the premise of step S0507 may also be processed in an order different from the order shown in FIG.
<Effect>

By using the video viewing system having the above configuration, it is possible to use comments to indicate the degree of excitement by each user without being influenced by the specifications of the video playback terminal device and without excessively hindering the viewing of the video. It becomes possible to express dynamically.
<< Embodiment 2 >>
<Overview>

The video viewing system according to the present embodiment is basically the same as the video viewing system according to the first embodiment, except that a comment font size or / and a comment screen occupancy amount are calculated according to the number of characters of each comment. A further feature is that two-screen occupancy information is transmitted.

<Functional configuration>

  FIG. 6 is a diagram illustrating an example of functional blocks of the moving image viewing system according to the present embodiment. As shown in this figure, the moving image viewing system of this embodiment includes a “moving image distribution server” 0610 and a “still comment distribution server” 0620, and the still comment distribution server has a “comment arrangement information transmission unit” 0621. . The comment arrangement information transmission unit includes a “second screen occupation amount information transmission unit” 0622. Since the basic configuration is the same as that of the moving image viewing system described with reference to FIG. 2 of the first embodiment, the function of the second screen occupancy amount information transmission unit, which is a difference, will be described below.

  “Second screen occupancy information transmission means” 0622 transmits a “second screen occupancy information” 0626 for calculating the font size of the comment and / or the screen occupancy of the comment according to the number of characters of each comment. Have The purpose of “comment font size and / or comment screen occupancy” is to display a comment that is particularly long when it is displayed, making it difficult to display other comments at the same time. Even if it does not go so far, the display of the comment or other comments is applied to the center of the screen, so that the situation of disturbing the display of the moving image itself is avoided. Therefore, by transmitting the second screen occupancy information having the above characteristics, it is possible to calculate and determine the font size or / and the screen occupancy for proper comment display in the video playback terminal device. As an example of “appropriate comment display”, the longer the comment is, the longer the comment is displayed at the top or bottom of the screen, and the comment is arranged so that the long comment is not displayed at the center of the screen I will take a plan.

  Here, the content of the calculation using the second screen occupation amount information will be described with a specific example. For one thing, in order to avoid the situation where it is difficult for the viewing user to read out a long comment, a part of the comment or It is conceivable to perform calculations so as to reduce the overall font size. It is an arbitrary design matter to calculate how much to make it smaller, but it is conceivable to calculate to determine the font size so that the video playback screen will be displayed in the full width, and the width of the same screen When a certain ratio (for example, 1/4) is exceeded, the calculation may be performed so as to reduce the font size. By adopting such a configuration, long comments are displayed over a wide area, and it becomes difficult for the user to read all within a predetermined continuous display time, or to display other comments. It is possible to avoid the situation of occupying the screen occupancy and to display many comments.

On the other hand, if the comment is a short sentence or only a word, the structure is such that the comment font size is increased or an operation that takes a larger display area is performed. Also good. As a result, it is possible to avoid a situation in which the impact on the viewer is reduced relative to other comments because the number of characters is small, and the comment can be highlighted. In this way, by adopting a configuration in which the impact of a comment is not diminished depending on the number of characters alone, it is possible to express the degree of excitement of the comment on the video by the font size and the number of occupied areas. . Note that these calculations can be realized more easily by using the information shown in FIG.
