Description

  The present invention relates to a content evaluation system and method, and more particularly to a content evaluation system and method for use in performing overall evaluation at the final stage of production of video content.

  In the production of content such as video with a time axis, a producer or the like may want to perform a subjective evaluation of the video immediately before final editing in the production stage.

  At the final stage of the video production process, the subjective evaluation as a video work is performed according to the timeline of the story progress. As a result, it is possible to improve the quality of the work by improving the quality of the work by correcting the production and refining the production.

  Conventionally, such a video evaluation has been performed by holding a preview, etc., where a viewer views the video, and totals the results using a questionnaire or the like. In conventional previews, etc., in order to enable viewers to concentrate on video evaluation, it is not possible to conduct a detailed questionnaire in real time, so questions can be asked in a lump after video viewing ends. Will be. For this reason, in the conventional evaluation, it has been difficult to accurately grasp the temporal change related to the interestingness of the video in synchronization with the progress of the video.

  On the other hand, as an evaluation site for movie and video content that has already been released, a site that scores content evaluation (whether it is interesting, worth watching, or not worth watching) by combining various ratings is popular. It has become. A representative example is Rotten Tomatoes (see Non-Patent Document 1, for example).

  The Rotten Tomatoes site does not itself review movies. The world's movie reviews are gathered, and the positive and negative ratios are tabulated with their own judgment. If more than 60% are positive, it is recognized as “Fresh”. 59% or less is “Rotten”. The subjectivity and will of the site is entered in the part of original judgment. The collected reviews are linked with key comments. Clicking on it, you can read the full text on the media's own website where the review is published. From the media point of view, there is an advantage that viewers increase through Rotten Tomatoes, and Rotten Tomates can collect content without the cost of hiring a writer to write reviews.

  Judgment by Rotten Tomates is the result of summarizing each review, and it is said that movies judged as “Fresh” are generally highly complete and often hit as they are. However, it is information for the end user that is valid only after the completed movie is released.

  Similarly, there is a site called Metametric (for example, see Non-Patent Document 2) or Movie review Intelligence (for example, see Non-Patent Document 3) that collects reviews.

  However, if you want to perform subjective evaluations through video during the production of content such as video with time axis, reactions such as “impression” and “degree of fun” of the viewer's video as temporal change data In order to measure or to input such data in a natural way, a system-like mechanism linked to some device is required.

  For example, Japanese Patent Application No. 2012-123649 “Content Evaluation System and Method” has a feeling that a general viewer who participates via a network is “impressed” or “disgusted” in order to realize such a function. In contrast, the present invention provides a method in which the viewer himself / herself can input naturally, and a mechanism in which the input method can be selected according to the viewer's preference. The present invention makes it possible to measure and record the viewer's reaction regarding the “interesting” of the content from each viewer using the respective natural input methods.

  On the other hand, when the general public actually enjoys a movie in an environment like a movie theater, or when they enjoy a video with a family at home, the subjective evaluation of the viewer views the same video. It is self-evident that there are factors that depend on the reactions of the surrounding viewers.

  When performing subjective assessments along the time axis, gather multiple viewers collected according to a profile in the same place and have them evaluated at the same time. It is possible to perform evaluations that are close to the state of enjoying video works together. However, in reality, in the preview, it is difficult to obtain many evaluations because the profiles of a plurality of viewers must be gathered to the desired profile and collected at the same time. A system that does this over a network is effective.

  However, Japanese Patent Application No. 2012-123649 “Content Evaluation System and Method”, which is a mechanism for performing subjective evaluation in a network, provides a mechanism for performing subjective evaluation in a group based on the reaction of surrounding viewers as described above. Not done. In other words, content evaluation in the group has a first problem that it is difficult to perform it on the network.

  Therefore, in order to solve the above problems, the present invention can give viewers participating individually in the same content evaluation on the network the feeling of watching in a group without interfering with content viewing, It is a first object of the present invention to provide a content evaluation system and method that can measure emotions for the content at that time.

  There is also a request from the evaluation side to prepare as many group profiles as possible when evaluating content in a group viewing state. However, in practice, there is a second problem that it is difficult to hold a preview and collect viewer groups of various profiles in the same place. In addition, this profile is a viewer's sex, age, residence area, etc.

  Therefore, in order to solve the above-mentioned problems, the present invention provides a content evaluation system and method for performing subjective evaluation in various profile groups with a very high degree of freedom. Objective.

  In order to achieve the above object, the present invention presents each viewer with the reaction of other viewers who are viewing the same content in a manner that minimizes the concentration of viewing, and provides a sense of group viewing.

  A rough operation of the content evaluation system 301 will be described with reference to FIGS. 3 and 4. The network preview is started when the evaluation center apparatus 200 issues an instruction to reproduce the video for group evaluation. In the case of group evaluation, the evaluation center apparatus 200 needs to control video reproduction so that viewers currently participating in the evaluation can view the content at the same time. When a plurality of participating viewers start measurement (evaluation), evaluation data of all the participating viewers is transmitted to the evaluation center device 200.

  The group subjective evaluation control apparatus 210 extracts a viewer ID that matches the age and sex conditions set in advance from all viewers participating in the subjective evaluation, and creates a group subjective evaluation viewer ID. To do.

  The group subjective evaluation control apparatus 210 receives real-time evaluation data having a group subjective evaluation viewer ID from the evaluation center apparatus 200 and sends them to the group subjective evaluation shared signal generation apparatus 220 as real-time group evaluation data.

  On the other hand, the group subjective evaluation control device 210 searches the past database for the evaluation data of the viewers that meet the above conditions among the viewers who have evaluated the video in the past. Then, the group subjective evaluation control device 210 sends them as offline group evaluation data to the group subjective evaluation shared signal generation device 220 in synchronization with the real-time group evaluation data in accordance with the video presentation time.

  As a result, the group subjective evaluation shared signal generation device 220 converts them and transmits them as a group subjective evaluation shared signal to the actuator of the terminal of the group evaluation viewer ID among the viewers currently evaluating the video. .

  Each component and its operation will be described in more detail.

(F) Group subjective evaluation control device 210
The group subjective evaluation control apparatus 210 is on the evaluation center apparatus 200 side, and has the following methods and means for performing control necessary for sharing the subjective evaluation of a plurality of viewers.

  The storage device 250 stores data (group profile) that specifies the age, sex, and other profiles of the group sharing the evaluation. The group subjective evaluation control device 210 refers to the group profile and refers to the group of contents. Identify viewers participating in subjective assessments and prepare to share subjective assessments. Note that the group subjective evaluation control device 210 generates a group profile in accordance with the set arbitrary condition and stores it in the storage device 250. The group subjective evaluation control device 210 also identifies viewers who have subjectively evaluated the same content in the past, and prepares to read the data. More specifically, it is as follows.

  The group subjective evaluation control device 210 uses the specified group profile among the identification numbers (subjective evaluation viewer IDs) of the viewers participating in the screening session (referred to as “net preview”) on the evaluation target content network. The matching viewer ID (group subjective evaluation viewer ID) is acquired. The group subjective evaluation control apparatus 210 stores the group subjective evaluation viewer ID in the storage device 260.

Further, the group subjective evaluation control device 210 refers to the group subjective evaluation viewer ID, extracts the real time evaluation data of the viewer that matches the specified group profile from all the real time evaluation data received from the evaluation center device 200, Real-time group evaluation data. The subjective evaluation viewer ID of the viewer participating in the network preview is given to the real-time evaluation data, and the group subjective evaluation control device 210 is designated by referring to the group subjective evaluation viewer ID. Real-time evaluation data of group profiles can be extracted.
As described above, the real-time group evaluation data is subjective evaluation data performed by viewers belonging to a group profile designated among viewers actually participating in the network preview.

  The group subjective evaluation control device 210 is a viewer who matches the specified group profile and has not participated in the current network preview, but has performed subjective evaluation of the same video work in the past. The past evaluation data of a certain viewer is read out from the evaluation data storage device 240 and used as offline group evaluation data.

  The group subjective evaluation control device 210 transfers the real-time group evaluation data and the offline group evaluation data to the group subjective evaluation shared signal generation device 220.

(G) Group subjective evaluation shared signal generator 220
In order to share another person's subjective evaluation, the evaluation data of the other viewers must be presented intuitively without disturbing the video evaluation performed by the viewer. For this purpose, the group subjective evaluation shared signal generation device 220 is a processing device (or software module) that performs a conversion process to appropriately present and present evaluation data of many viewers. The group subjective evaluation shared signal generation device 220 considers the response characteristics of the group subjective evaluation shared actuator 230 for presenting subjective evaluation information to be shared to the viewer. For example, the group subjective evaluation shared signal generation apparatus 220 considers the range of information that can be simultaneously presented by the group subjective evaluation sharing actuator 230, and when the evaluation data of other viewers are generated at the same time, the generation time of those signals Is delayed by a predetermined value and converted into a continuous signal. As another example of the above processing, an upper limit may be set for the number of evaluation data that occurs simultaneously in the viewer. These processing contents are shown in the embodiment.

(H) Group Subjective Evaluation Sharing Actuator 230
The content evaluation system 301 according to the present embodiment says that when a viewer inputs subjective evaluation while watching a video, the response of other viewers watching the same video work (that is, a positive signal that is interesting and not interesting) Negative signal) must be presented to the viewer in a way that does not interfere with subjective evaluation, and the state of sharing reactions within the group must be reproduced. In order not to hinder the viewer's ability to concentrate on the video, the content evaluation system 301 needs to avoid presenting the reactions of other viewers directly on the screen where the video is being viewed.

  Further, the group subjective evaluation sharing actuator 230 needs to present at least two types of information, positive and negative, and the generation timing thereof based on the group subjective evaluation sharing signal. Further, the group subjective evaluation sharing actuator 230 presents subjective evaluation information of a plurality of other viewers at the same time, that is, intuitively knows whether many people have responded or not so much, and the whole It is necessary to present so that the tendency of can be intuitively understood.

  In order to satisfy the above conditions, it is desirable to additionally display other viewers' responses on the evaluation data input device 1 so as not to affect the image quality and sound quality of the evaluation target video, for example. As a means, it is possible to use simple light presentation such as expressing positive and negative by color by simple blinking of light, or distinguishing positive and negative by frequency by element vibration. The group subjective evaluation sharing actuator 230 can realize these.

(I) Evaluation data storage device 240
The evaluation data storage device 240 stores real-time evaluation data output from the evaluation center device 200. The offline group evaluation data is generated from the evaluation data stored in the evaluation data storage device 240 from the evaluation data of the viewers who belong to the specified group profile and evaluated the same video work in the past. Is done.

(J) Storage device 250
The group profile data is data specifying the age, sex, and other group profiles of the group sharing the evaluation. For example, a person who wants a viewer to evaluate content sets conditions such as age and sex to be evaluated in advance, so that the group subjective evaluation control device 210 generates group profile data, and the storage device 250 Remember.

(K) Storage device 260
The group subjective evaluation control apparatus 210 extracts the viewer ID that matches the group profile data from all the viewers participating in the network preview, and creates a subjective evaluation viewer ID. The storage device 260 stores the created subjective evaluation viewer ID. The subjective evaluation viewer ID includes viewers who have subjectively evaluated the same content in the past.

(L) Storage device 270
The content ID is an ID that designates content to be subjected to group subjective evaluation. The storage device 270 stores the content ID.

  The content evaluation system 301 and the content evaluation method according to the present embodiment present the reactions of other viewers who are viewing the same content in a manner that minimizes hindering the concentration of viewing by the target viewer. . Accordingly, the content evaluation system 301 and the content evaluation method can create a state where the content is being viewed in a group. Then, the content evaluation system 301 and the content evaluation method can evaluate the content in the group appreciation by inputting or measuring and recording the viewer's emotion that is impressed, excited, uninteresting or disgusting. It can be realized with a network.

  In addition, the content evaluation system 301 and the content evaluation method according to the present embodiment meet the request from the evaluation side to prepare as many group profiles as possible when performing subjective evaluation of a video work to be evaluated in a group appreciation state. I can respond. That is, the content evaluation system 301 and its content evaluation method can perform subjective evaluation in group viewing of various profiles with a very high degree of freedom.

(Example)
(1) Composition of Subjective Evaluation Data Subjective evaluation data in the content evaluation system 301 and the content evaluation method is a subjective input by a viewer using the evaluation data input device 1 and is a subject of subjective evaluation. It consists of two types of event occurrence time data based on the progress time of the work. For example, the viewer is required to press the positive switch of the evaluation data input device 1 when it feels “interesting” and to press the negative switch when it feels “not interesting”. Subjective evaluation data is recorded as the occurrence time of these two types of events.

(2) Group Subjective Evaluation Sharing Actuator 230
In order to perform group content evaluation on a network, viewers need to intuitively share evaluation data of other viewers who view the same video work during viewing. In other words, it is necessary for viewers to feel the evaluation of other viewers in a form that does not interfere with their own video evaluation while viewing the video, and to bring them closer to a state in which reactions within the group are shared. Of course, it is necessary to avoid presenting information on the screen that is directly viewing the video. In addition, the signal to be notified to the viewer needs to present at least two types of information, positive and negative, the generation timing (evaluation timing), and subjective evaluation information of a plurality of other viewers at the same time. In particular, it is necessary to display subjective evaluation information of other viewers so that the overall tendency can be intuitively understood.

  There are roughly two methods for notifying other viewers' subjective evaluation information. One is the presentation of simple monochromatic light. Since complex images and graphics hinder viewers from viewing images, simple light emission is used. Another method is presentation by vibration of the input device for evaluation.

  More specifically, for example, by attaching a light to the evaluation data input device 1 and expressing positive and negative by colors by simply blinking light, the viewer can intuitively feel the reaction of other viewers. be able to. In the case of the vibration of the element, by using the vibration of the evaluation data input device 1, it is possible to recognize the reaction of other viewers so as not to disturb the viewing of the music or speech of the video work. Moreover, positive and negative can be distinguished by the frequency of vibration or the pattern of vibration.

  Next, the function of the group subjective evaluation sharing actuator 230 will be described in detail. In the following, a case will be described where the evaluation data input device 1 is provided with a light and notifies evaluation data of other viewers using simple monochromatic light emission.

  The evaluation data input device 1 has a push button for positive emotion and a push button for negative emotion, these buttons are covered with semi-transparent plastic hemispheres of different colors, and a light emitting diode is installed inside. It is.

  The group subjective evaluation sharing signal 230 is input to the group subjective evaluation sharing actuator 230 in two channels, and the positive side light emitting diode or the negative side light emitting diode is turned on according to these signals. Since the signals are independent, they can be lit at the same time. When the group subjective evaluation sharing actuator 230 receives the group subjective evaluation sharing signal as a pulse, it generates an electric signal having a smooth waveform and turns on the light emitting diode.

(3) Processing of Group Subjective Evaluation Shared Signal Generation Device 220 When many viewers press positive at the same time, the group subjective evaluation control device 210 converts the evaluation data into real-time evaluation data, and the group subjective evaluation sharing is performed. This is transmitted to the signal generator 220. The group subjective evaluation shared signal generation device 220 processes real-time evaluation data with software for generating a subjective evaluation shared signal, and converts it into a continuous group subjective evaluation shared signal delayed by about 100 to 250 msec. The group subjective evaluation shared signal is converted into a signal for lighting the light emitting diode by the group subjective evaluation shared actuator 230. As a result, the light emitting diodes of the evaluation data input device 1 are continuously lit. Note that the group subjective evaluation shared signal generation device 220 may generate a group subjective evaluation shared signal based on the greater subjectivity when the viewer's subjectivity is divided into positive and negative.

  When many viewers make a positive reaction, the lighting time of the light emitting diode becomes longer, so that the viewer can intuitively recognize that many other viewers are reacting positively. That is, viewers can intuitively share other viewers' reactions with simple lighting.

  The group subjective evaluation shared signal generation apparatus 220 applies a maximum value of positive or negative events that occur simultaneously when generating the group subjective evaluation shared signal. For example, when the number of viewers who responded at the same time exceeds several tens of people, since the lighting time continues for several seconds or more, there is a possibility that new evaluation regarding the next scene or the like may not be reflected. For this reason, the group subjective evaluation shared signal generation apparatus 220 may set a certain upper limit and ignore further events.

  The group subjective evaluation shared signal generation device 220 designates evaluation data (offline group evaluation data) of viewers of the same video work and the same group profile in past evaluation data that is not real-time, and uses the evaluation data as an evaluation session. It can be sent to the viewer along with real-time group evaluation data as time progresses. Thereby, the content evaluation system 301 can use past evaluation data for group evaluation.

(effect)
The content evaluation system 301 can intuitively share the reactions of a plurality of other viewers even when performing subjective evaluation of videos individually through a network, and evaluate content that is close to subjective evaluation when viewing in a group. It can be implemented according to the time axis. In addition, the content evaluation system 301 can obtain evaluation results of a plurality of groups in one net preview by setting a plurality of group profiles.

(Appendix)
1 and 2, (a) an evaluation data input device 1, (b) an evaluation data collection / control apparatus 100, (c) an evaluation content control file 2, (d) an evaluation video file 3, (e) The operation of the evaluation center apparatus 200 will be described.

(A) Evaluation data input device 1
The evaluation data input device 1 inputs an impression of “interesting” to the viewer's content and measurement data related thereto in real time without disturbing the viewer's concentration of content viewing. The first feature of the function is that it is provided with a function capable of acquiring evaluation data in a natural manner in real time without interrupting the viewer's concentration on the content while viewing the content. Furthermore, the second feature has a function of inputting “interesting” (positive) and “dislike” (negative) in a natural manner without disturbing the viewer's concentration of content viewing. That is.

  As a mechanism for inputting “impressions” without disturbing the viewer's concentration on content viewing, the user can select from several input method options in a form that does not feel uncomfortable even when placed in human hands for a long time. It can be realized by installing a function that can be selected by the user and a mechanism that allows natural input with simple actions.

  The evaluation data collection control device 100 and the evaluation data input device 1 are connected by some communication means (wired, wireless, optical, laser, infrared, etc.). Data from the evaluation data input device 1 is transferred to the evaluation data collection controller 100 in real time by the communication means described above.

(B) Evaluation data collection control device 100
The evaluation data collection control apparatus 100 manages the elapsed time of the content to be evaluated, and collects evaluation data from the evaluation data input device 1 in synchronization with the reproduction time. The collected evaluation data is transmitted to the evaluation center apparatus 200 via the network in real time as it is. Alternatively, the evaluation data collection control device 100 may process the evaluation data and store it as a file.

  The evaluation data collection control device 100 is suitable for the content structure by adaptively changing the time constant of data smoothing using the evaluation content control file 2 composed of data obtained by analyzing the content structure. Evaluation is possible.

  Specifically, the evaluation data collection control device 100 smoothes the data for the evaluation data obtained from the evaluation data input device 1 based on a content control signal such as time synchronization of the evaluation content control file 2. By appropriately changing the time constant of, evaluation suitable for the structure of the content becomes possible. Smoothing is, for example, adjusting the playback time by fast-forwarding or thinning out a scene with almost no change in video as shown in FIG.
