Thereby, it is possible to prevent inappropriate information from being presented to the user.

(Apparatus configuration of the first embodiment)
A streaming information reproduction control system according to a first embodiment of the present invention will be described with reference to the accompanying drawings. In this embodiment, an example in which moving image information is handled as streaming information will be described. However, the moving image may be accompanied by voice or text data.

  This system includes a streaming information distribution server 1, a client terminal 2, a management server 3, and a network 4 connecting them (see FIGS. 1 and 2). In FIG. 2, a plurality of client terminals are illustrated, but since all have the same configuration, the same reference numerals are given to all of them.

  The distribution server 1 stores streaming information to be distributed to the client terminal 2. The distribution server 1 can distribute streaming information to the client terminal 2 based on a request from the client terminal 2.

  The client terminal 2 includes a redirect program 21 and a browser 22.

  The redirect program 21 includes a moving image data acquisition unit 211 and a moving image data transmission unit 212 (see FIG. 2). The moving image data acquisition unit 211 is a module or program for acquiring streaming information distributed from the distribution server 1 to the client terminal 2. The moving image data acquisition unit 211 corresponds to a streaming information acquisition unit that acquires streaming information distributed via a network. The moving image data transmission unit 212 is a module or program for transmitting moving image data from the client terminal 2 to the management server 3.

  The browser 22 is a program that requests the distribution server 1 to distribute information. The browser 22 has a function of receiving streaming information distributed from the management server 3 and sequentially reproducing it. That is, the browser 22 of this embodiment has a function of moving image reproduction software. As a result, the client terminal 2 can perform processing for reproducing the streaming information distributed from the management server 3 and presenting it to the user. Even if the browser itself does not have such a function, it is possible to function as the browser 22 of the present embodiment as a whole by using an appropriate plug-in. Examples of browsers that can be used for such purposes include web browsers (Internet Explorer, Netscape, etc.) that browse web pages, and media playback programs (media players, real players, quick time, etc.) that play video and audio. There is. These names are registered trademarks or trademarks.

  The management server 3 includes a moving image data receiving unit 31, a moving image analysis unit 32, an inappropriate moving image block unit 33, and a moving image distribution unit 34.

  The moving image data receiving unit 31 receives moving image data sent from the client terminal 2 to the management server 3 by the redirect program 21.

  The moving image analysis unit 32 sequentially performs time-series analysis to determine whether or not the inappropriate content is included in the streaming information. Detailed processing contents will be described later as the operation of this system. The moving image analysis unit 32 corresponds to a streaming information analysis unit that analyzes whether or not inappropriate content is included in the streaming information.

  The moving image analysis unit 32 of the present embodiment has a comparison DB 321. The comparison DB 321 is a DB that stores images for determining inappropriate moving images. When determining inappropriate information other than images (for example, words), the information is also stored. In this example, the comparison DB 321 is placed inside the management server 3. However, the present invention is not limited to this, and the comparison DB 321 can be arranged in another node connected via the network 4. Information such as images stored in the comparison DB 321 is collected mechanically or manually.

The inappropriate video block 33
(1) If the streaming information does not include inappropriate content, the streaming information is sequentially distributed to the client terminal 2 via the video distribution unit 34,
(2) When inappropriate content is included in the streaming information, a process of blocking reproduction of streaming information including the inappropriate content is performed. The block unit 33 corresponds to “a streaming information block unit that blocks reproduction of streaming information including inappropriate content when the streaming information includes inappropriate content”.

  Here, “blocking streaming information playback” means either “stop streaming information distribution” or “delete or replace inappropriate portions of streaming information for distribution” Means. Details of this processing will also be described later.

  The moving picture distribution unit 34 corresponds to a “streaming information reproduction processing unit that sequentially reproduces streaming information when inappropriate content is not included in the streaming information”. That is, the moving image distribution unit 34 can continuously reproduce the streaming information by distributing the streaming information to the client terminal 2. In FIG. 2, a moving image distribution unit 34 is arranged downstream of the inappropriate moving image block unit 33. However, if the streaming information does not include inappropriate content, the block unit 33 does not function. That is, in this case, the streaming information is substantially sent from the moving image analysis unit 32 to the moving image distribution unit 34.

  The network 4 is the Internet in this example. However, the network 4 may be any network that can perform necessary communication between nodes (servers and terminals). The protocol used in the network 4 and the configuration in the physical layer are not particularly limited.

(Streaming information playback control method)
Next, a reproduction control method according to the present embodiment will be described with reference to FIGS.

(Step SA-1)
First, based on the user's operation, the browser (video playback software) 22 requests the video distribution server 1 to distribute a video. The moving image distribution server 1 receives this request via the network 4.

(Step SA-2)
Next, the moving image distribution server 1 distributes the moving image (streaming information) to the client terminal 2 in response to the request from the browser 22. This distribution is performed via the network 4. Streaming information means continuous data in time series, such as video and audio. Of course, it may be streaming data that is divided into packets and transmitted discontinuously. In the case of streaming information, the client terminal 2 can simultaneously reproduce while receiving the data. When streaming information is used, there is an advantage that multimedia data can be easily reproduced, even if the line is low speed, as compared with the download method.

  In the client terminal 2, the moving image distributed in this way is sequentially received by the redirect program 21. That is, the redirect program 21 can intercept the streaming information to be delivered to the browser 22. For example, the redirect program 21 is configured to be add-in to the browser 22, monitors data transmitted / received by the browser 22, and sequentially transmits the received data to the management server 3 registered in advance.

  More specifically, the moving image data acquisition unit 211 of the redirect program 21 receives a moving image from the distribution server 1. Next, the moving image data transmission unit 212 sequentially transmits moving images to the management server 3 via the network 4.

(Step SA-3)
The moving image data receiving unit 31 of the management server 3 receives moving images from the client terminal 2 and sequentially sends them to the moving image analyzing unit 32.

(Step SA-4)
The moving image analysis unit 32 sequentially analyzes the received moving images in time series. That is, the moving image analysis unit 32 analyzes whether or not inappropriate content is included in the moving image as the streaming information. This analysis method will be described with reference to FIG.

  The moving image analysis unit 32 extracts still images (scenes) constituting the moving image along the time series of the streaming information. Specifically, for example, the frames constituting the moving image are extracted. Alternatively, an I frame (I picture) may be extracted if it is data encoded in MPEG2. FIG. 3 shows seven scenes No. 1 to No. 7 extracted in this way. Of course, the number of scenes is an example.

  Each scene is collated with an inappropriate image stored in the comparison DB 321. Thereby, it can be determined whether or not each scene has inappropriate contents. In this example, the No. 2 to No. 6 scenes are determined to be inappropriate, and the remaining scenes are determined to be appropriate. This example is an example of determination in frame units (scene units).

  As a method for determining an inappropriate image, for example, the technique described in Japanese Patent Application Laid-Open No. 2007-96608 can be used. Therefore, detailed description is omitted in this specification.

(Step SA-5)
The inappropriate moving image block unit 33 receives the analysis result (see FIG. 3) from the moving image analysis unit 32. Next, the block unit 33 replaces an inappropriate scene in the inappropriate moving image with another appropriate scene. An appropriate scene to be used for replacement can be recorded in advance in a database (not shown) in the management server 3. Examples of suitable scenes used for replacement include:
・ Some still images (for example, images of flowers and scenery)
-An image showing text information (for example, “Distributable” characters)
-It can be a single color image such as white. In short, any image can be used as long as it can prevent distribution of inappropriate images.

  The moving images in which inappropriate images are blocked in this way are sequentially sent to the moving image distribution unit 34. Streaming information that does not include inappropriate images passes through the block unit 33 and is sent to the moving image distribution unit 34 as it is.

(Step SA-6)
The moving image distribution unit 34 sends the moving image in which the inappropriate moving image is blocked to the browser (moving image reproduction software) 22 via the network 4. The browser 22 sequentially reproduces the received moving image.

  In the present embodiment, a moving image in which inappropriate images are blocked can be sequentially played back and presented to the user as streaming information. That is, according to the present embodiment, the content of an inappropriate video can be replaced, and streaming information including the replaced content can be reproduced. Thus, according to the present embodiment, there is an advantage that inappropriate images can be filtered.

  In addition, when the streaming information does not include inappropriate information, the streaming information can be continuously reproduced by the browser 22 as it is.

  In the embodiment, an analysis is performed as to whether or not an image in a moving image is inappropriate. Here, when characters are included in the image, whether or not the characters are inappropriate can be sequentially analyzed in time series. In other words, the characters are recognized and sequentially extracted, and a word composed of the characters is compared with an inappropriate word recorded in the comparison DB 321 to determine whether the image is an inappropriate image. it can. Such an operation can be performed using an appropriate character recognition technique (OCR technique) or morphological analysis technique. Of course, when there is no inappropriate word, the streaming information can be reproduced as it is.

  Furthermore, when sound is attached to the moving image, the sound can be sequentially analyzed. That is, the speech is recognized and converted into a character string, and a word composed of the character string and an inappropriate word recorded in the comparison DB 321 are sequentially compared to determine whether the information is inappropriate information. You can also In this case, the streaming information can be delivered to the browser 22 and played back with the sound cut off. Alternatively, the streaming information can be distributed and reproduced after the sound is replaced with another sound. Such an operation can be performed by using an appropriate speech recognition technique or morphological analysis technique.

  In the embodiment, a moving image is used as streaming information. However, streaming information consisting only of audio may be used. Also in this case, as described above, inappropriate information in the voice can be determined and its distribution can be blocked.

  In the embodiment, the process of replacing an inappropriate image when an inappropriate moving image is found is exemplified. However, the present invention is not limited to this. For example, the streaming information itself may be stopped. Alternatively, it is possible to stop the reproduction of the streaming information by operating the browser 22 by the management server 3.

(Second Embodiment)
Next, a streaming information reproduction control system according to a second embodiment of the present invention will be described with reference mainly to FIG. Also in this embodiment, an example in which moving image information is handled as streaming information will be described. However, the moving image may be accompanied by voice or text data. In the description of the second embodiment, the same reference numerals are used for constituent elements having basically the same functions as those of the first embodiment described above, thereby simplifying the description.

  This system includes a streaming information distribution server 100, a client terminal 200, a management server 300, and a network 4 (see FIG. 1) connecting them.

  Since the distribution server 100 and the network 4 may be basically the same as the distribution server 1 in the first embodiment, detailed description thereof is omitted.

  The client terminal 200 includes a gateway program 201 and a browser 202.

  The gateway program 201 includes a moving image data acquisition unit 2011, a moving image analysis unit 2012, a comparison DB 2013, and a block unit 2014.

  The moving image data acquisition unit 2011 is a module or program for acquiring streaming information distributed from the distribution server 100 to the client terminal 200. The moving image data acquisition unit 2011 corresponds to a streaming information acquisition unit that acquires streaming information distributed via a network.

  The moving image analysis unit 2012 performs a process of analyzing whether or not inappropriate content is included in the streaming information. The specific processing content is basically the same as that of the moving image analysis unit 32 in the first embodiment. The moving image analysis unit 2012 corresponds to a streaming information analysis unit that analyzes whether or not inappropriate content is included in the streaming information.

  The comparison DB 2013 is a part that stores information such as inappropriate moving images. The contents of the comparison DB 2013 are appropriately updated by accessing the management server 300.

The inappropriate video block 2014
(1) If the streaming information does not contain inappropriate content, the streaming information is sequentially delivered to the browser 202,
(2) When inappropriate content is included in the streaming information, a process of blocking reproduction of streaming information including the inappropriate content is performed. The block unit 2014 corresponds to “a streaming information block unit that blocks reproduction of streaming information including inappropriate content when the streaming information includes inappropriate content”. The configuration of the block unit 2014 is basically the same as that of the block unit 33 in the first embodiment.

  The browser 202 is a program that requests the distribution server 100 to distribute information. Further, the browser 202 has a function of receiving and playing back streaming information that has passed through the block unit 2014. That is, the browser 202 of this embodiment has a function of moving image reproduction software. As a result, the client terminal 200 can perform processing for reproducing the streaming information distributed from the distribution server 100 and presenting it to the user. The configuration of the browser 202 is basically the same as that of the browser 22 in the first embodiment. In the second embodiment, the browser 202 corresponds to “a streaming information reproduction processing unit that sequentially reproduces streaming information when inappropriate content is not included in the streaming information”.

  The management server 300 holds update information for determining inappropriate videos. In response to a request from the comparison DB 321, the management server can send update information to the comparison DB 321 and update the information.

(Streaming information playback control method in the second embodiment)
Next, a reproduction control method according to the present embodiment will be described with reference to FIG.

(Step SB-1)
First, based on the user's operation, the browser (video playback software) 202 requests the video distribution server 100 to distribute a video. The moving image distribution server 100 receives this request via the network 4 (see FIG. 1).

(Step SB-2)
Next, the moving image distribution server 100 distributes the moving image (streaming information) to the client terminal 200 in response to the request from the browser 202. This distribution is performed via the network 4.

  In the client terminal 200, the moving image distributed in this way is received by the gateway program 201. That is, the gateway program 201 can intercept the streaming information to be distributed to the browser 22.

  More specifically, the moving image data acquisition unit 2011 of the gateway program 201 receives a moving image from the distribution server 100. Furthermore, the moving image data acquisition unit 2011 sends the received moving image to the moving image analysis unit 2012. Here, in the first embodiment described above, the moving image is distributed to the management server 3 and analyzed there. On the other hand, in the second embodiment, such distribution is not performed, and the moving image analysis is performed in the client terminal 200 as described later.

(Step SB-3)
The moving image analysis unit 2012 sequentially analyzes the moving image received from the moving image data acquisition unit 201 in time series. That is, the moving image analysis unit 2012 sequentially analyzes whether or not inappropriate content is included in the moving image as the streaming information. This analysis method is basically the same as that of the moving image analysis unit 32 in the first embodiment. However, in this embodiment, a comparison DB 2013 is used in place of the comparison DB 321 in order to determine inappropriate videos.

(Step SB-4)
The inappropriate moving image block unit 2014 receives the analysis result (see FIG. 3) from the moving image analysis unit 2012. The operation of the block unit 2014 is basically the same as that of the block unit 33 in the first embodiment. The operation of the block unit 2014 enables processing such as replacing inappropriate images.

(Step SB-5)
The moving image block unit 2014 sends the moving image in which the inappropriate moving image is blocked to the browser (moving image reproduction software) 202. The browser 202 reproduces the received moving image. Thereby, the client terminal 200 can present a moving image to the user. If there is no inappropriate image, the moving image (streaming information) can be sent to the browser 202 and continuously reproduced as it is.

  In the present embodiment, a moving image in which inappropriate images are blocked can be played and presented to the user. That is, according to the present embodiment, there is an advantage that inappropriate images can be filtered.

  Further, in the present embodiment, it is possible to analyze a moving image and block an inappropriate moving image without distributing the moving image to the management server, so that it is possible to reduce the burden on the network.

  Other configurations and advantages of the second embodiment are basically the same as those of the first embodiment.

  The operations of the above-described embodiments can be implemented by incorporating appropriate computer software into the computer.

  The reproduction control method and apparatus according to the present invention are not limited to the above embodiment. In the present invention, various modifications can be made to the specific configuration within the scope of the claims.
