In 73, the image information is passed to the image information editing unit 272.

The image information editing unit 272 edits the minutes passed from a minutes editing unit 277, which will be described later, by embedding the unique information of the speaker by digital watermark technology, or by editing the voice information editing unit 273 or the minutes. Editing is performed to display the information on the minutes acquired through the unit 277 or the network 10 on the video output screen 22. In addition,
The information acquired from the video input camera 21 and the edited minutes are stored in the image information storage unit 275.

When the minutes are represented by text information, the voice information editing unit 273 recognizes the voice of the attendee, which is the voice information input from the voice input microphone 23, and converts the voice information into text information. The converted character information is stored in the character information storage unit 278 together with the speaker-specific information. Also, when expressing the minutes as voice information,
The name of the speaker acquired from the voice input microphone 23 is added to the voice information and stored in the voice information storage unit 276.

The minutes editor 277 is a voice information editor 2
In 73, every time there is a statement, it is converted into character information,
The character information stored in the character information storage unit 278 is edited into the minutes when the video conference ends. The minutes editing unit 277 converts the character information stored as the minutes in the character information storage unit 278 into voice information, temporarily stores it as the voice minutes in the voice information storage unit 276, and stores the voice information at the time of output. It is also possible to output from the audio output device 24.

The image information editing unit 272 is the minutes editing unit 2
Edited as the minutes in 77, or edited to display the information stored in the character information storage section 278 as the minutes on the screen, which is converted into character information for each statement in the voice information editing section 273. I do. At this time, the digital watermark embedding processing unit 274 is instructed to embed information unique to the speaker by the digital watermark technique.

The digital watermark embedding processor 274 has the following functions. FIG. 6 is a diagram for explaining the operation of the digital watermark embedding processing unit of the present invention. The digital watermark embedding technology embeds other information in digital information (image (still image, moving image), audio) so that it is not perceived by humans, and the embedded information can be taken out when necessary. Is.

The principle of the digital watermark technique will be described below with reference to FIG. 6 when the digital information is image information. For details, see Japanese Patent Application No. 8-305370 and Japanese Patent Application No. 8-
See 338769. FIG. 6A is a diagram showing a flow of processing when another information (embedded information) is embedded in the image information. In the decomposition processing (step 101), one block is decomposed into a plurality of blocks each of which has n pixels × m pixels. In the case of a moving image, it is divided into frames and the like, and each frame is decomposed into a plurality of blocks.

In the orthogonal transform process (step 102), orthogonal transformation such as discrete cosine transform (DCT transform) is applied to each block decomposed in the decomposing process (step 101) to obtain an n × m frequency component matrix. Prior to embedding the embedding information, a random number is used to determine the embedding position that determines the position of the frequency component matrix obtained by the orthogonal transform processing to embed the embedding information, and the frequency component value is changed to that position. A change amount indicating whether to perform is determined, and the determined embedding position and the change amount are acquired as key information. In the embedding process (step 103), when embedding the embedding information, it is not necessary to embed all in the frequency component matrix for one block, and it is also possible to embed it over the frequency component matrices of a plurality of blocks. As the embedding position, for example, by selecting the low frequency part of the frequency component matrix, it is possible to embed it so that it cannot be perceived by humans. Also, by changing the change amount, the difference from the original value of the frequency component matrix can be changed,
It is possible to control deterioration of image quality. In the embedding process, the value of the frequency component matrix of each block is changed based on the embedding position of the key information and the amount of change, and the embedding information is embedded.

In the inverse orthogonal transform process (step 104),
The frequency component matrix of each block in which the embedded information is embedded by the embedding process is inversely orthogonally transformed to obtain a block image of n pixels × m pixels. In the reconstruction process (step 105), the block images obtained in the inverse orthogonal transform process (step 104) are joined together to obtain a watermark image in which embedded information is embedded.

FIG. 6B is a diagram showing the flow of processing when an embedded image of a watermark image is taken out. In the decomposition processing (step 201), the watermark image is decomposed into a plurality of blocks each having n pixels × m pixels. In the orthogonal transformation process (step 202), the decomposition process (step 20)
An orthogonal transformation is performed on each of the blocks decomposed in 1) to obtain an n × m frequency component matrix. In the extraction process (step 203), the embedding process (step 10)
Obtain the embedding position and the amount of change from the key information used in 3),
The embedded information is extracted from the frequency component matrix of each block.

When the digital information is voice information, the concrete processing method at the time of embedding and taking out is different from the case of the image information, but like the case of the image information,
The embedded information is embedded in the redundant portion of the audio information, the position information and the like are used as key information, and the embedded information can be embedded and extracted based on this key information. As described above, in the digital watermark technology, the embedded information cannot be taken out without the key information used at the time of embedding, and the embedded information in the key information is not fixed because it is created by a random number, and the embedded information cannot be decrypted. It is difficult, by embedding the embedded information so that it cannot be perceived by humans by devising the embedding position, and by changing the amount of change, the degree of deterioration of the image quality can be controlled.

The digital watermark embedding processing unit 274 has the key information and image information editing unit 2 acquired from the information acquisition unit 271.
The embedded information is embedded in the minutes based on the minutes acquired from 72. The image information storage unit 275 stores the image information of the minutes edited by the image information editing unit 272.

The character information storage unit 278 stores the content of the statement converted into the character information by the voice information editing unit 273. Next, the video conference control terminal 28, in the process of proceeding the video conference, the video input camera 21, the video output screen 22, the audio input microphone 23, the audio output device 24,
It controls the ID card reader 25, the personal identification device 26, the video conference information processing device 27, the video conference control terminal 28, and the like.

[0038]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 7 is a flowchart of the minutes creating process according to the embodiment of the present invention. Step 301) First, when using the video conference terminal 20, the attendee A first inserts a user ID or password into the video conference terminal 20, or inserts an ID card into the ID card reader 25, User ID
Or enter the password. Alternatively, he / she shoots his / her face toward the video input camera 21 and says “I am A” to my voice input microphone 23.

Step 302) The personal identification device 26
The information input by any of the above methods and the information registered in advance are collated, and if they match, the user of the terminal is determined to be used by the attendee A. (Step 303) Next, when the video conference starts, the minutes are created in parallel.

First, the speech contents of each attendee are acquired by the information acquisition unit 271 of the video conference information processing apparatus 27, and voice recognition processing is performed by the voice recognition function of the voice information editing unit 273 to create the minutes. Step 304) The voice information subjected to voice recognition is converted into text information in the voice information editing unit 273.

Step 305) The converted character information is stored in the character information storage unit 278. At this time, it is determined in step 301 and step 302 described above who is speaking.
Since it is already known, the name of the speaker is added to the end of the speech content after voice conversion. Step 306) In the minutes editor 277, the contents of the proceedings accumulated in the character information accumulator 278 are corrected and the final preparation is made.

Step 307) Image information editing section 272
, The digital watermark embedding processing unit 274 is added to the character information in the conference stored in the character information storage unit 278.
The information (name, etc.) of the speaker embedded in is embedded. Step 308) In the image information editing unit 272, the information of the embedded speaker is edited so as to be collectively displayed at an arbitrary place such as the end of the image in a visible form, or in synchronization with the proceedings of the proceedings. The character information in which the unique information of the speaker is embedded by the digital watermark embedding process provided by the editing unit 277 may be edited so as to be arbitrarily divided and displayed on the video output screen 22.

Next, a series of processes for embedding the name of the speaker behind the content of the message by the digital watermark technique and displaying it as image information will be described. Image information editing unit 27
The digital watermark embedding processing unit 274 embeds the name and ID of the speaker into the utterance content edited into the character information by the voice information editing unit 273, acquires the information, and stores it in the image information storage unit 275. Store it.

At this time, if the embedding process is performed more strictly, the digital watermark embedding processing unit 274 digitally signs the secret key (RSA or the like) of the speaker (this secret key is stored in the ID card or in the video conference). Enter the information set in the terminal). It should be noted that the present invention does not limit the fact that the speaker knows / does not know that the watermark useful for preventing the repudiation of the message content is embedded in his / her message.

In the above, the character information stored in the character information storage unit 278 is edited in the minutes editing unit 277, transmitted to the network 10 via the image information editing unit 272, and received via the network 10. The video conference terminal 20 can acquire the image information in which the watermark is inserted. FIG. 8 shows an image of the minutes thus obtained via the network 10. In the figure, the name, ID, etc. are actually invisible because they are encrypted and embedded uniquely to the speaker.

Furthermore, when displaying the minutes, the image information editing section 272 can control the font change at the time of digital embedding when displaying the speech of the attendees on the video output screen 22. . An example of this is shown in FIG. In the example of the figure, the font change control is performed so that (Yamamoto) 's message contents are displayed in blocks,
(Onishi) and (Nishikawa) are displayed in Mincho style. In order to realize this, the method shown in FIG. 10 is used. In FIG. 10, when the utterance contents are input in blocks, the conversion key P is input by the font change control by digital embedding processing, and the input block font is converted to Mincho font. Is output. In this way, the font order is determined by designating the conversion key P from the terminal and inputting the utterance content to the conversion (encryption) function F.

Further, in the above example, as the minutes, the voice information is converted into the character information and held in the character information storage unit 278, and the character information is stored in the image information editing unit 272 as the minutes. However, the minutes can be provided as voice information without being limited to this example. An example thereof will be described with reference to FIG. Figure 1
FIG. 1 is a flowchart showing the operation of creating a voice minutes according to an embodiment of the present invention.

Step 401) The operation of the video conference system is started, and the person recognizing device 26 associates the attendee with the terminal. Step 402) When creating a voice minutes, the process proceeds to the following process, and when creating a minutes by text information without creating, the process proceeds to the above process and the process ends.

Step 403) When the condition selection minutes creation type creates the minutes by adding the speaker name to the voice information of the utterance contents, the voice information editing unit 273 displays the acquired utterance contents as character information. The voice information (statement content) is stored in the voice information storage unit 276 in parallel with the progress until the video conference is ended without converting
Move to 06.

Step 404) Audio information editing section 273
In the case where the text information is converted into the text information, the text information in which the embedding process is performed is acquired / edited every time the utterance is made. Step 405) The edited character information is converted into voice information in the voice information editing unit 273 and stored in the voice information storage unit 276.

Step 406) Audio information storage unit 276
The voice information stored in is output. As described above, the present invention is roughly classified as follows as a method of editing the minutes. Unique information (name, ID, etc.) for specifying the speaker is added to the voice information acquired from the speaker, and the minutes are accumulated as voice information.

The voice information obtained from the speaker is converted into character information, and the information is embedded by the digital watermark technique and output as the minutes. The text minutes are converted into voice information again and stored as voice minutes. The timing at which the minutes are generated is set to the time when there is a statement during the video conference, and the above processing is performed for each statement.

The timing at which the minutes are generated is the end time of the video conference, and each time there is a utterance, it is simply retained as utterance information (character information or voice information), and after the end of the conference, the characters accumulated during the conference are stored. Edit the minutes or voice minutes by integrating them. For voice information, information for identifying the speaker is set with or without applying the digital watermark technology.

In the present invention, it is possible to appropriately select or combine the above-described minutes editing methods. The present invention is not limited to the above embodiments, and various modifications and applications are possible within the scope of the claims.

[0055]

As described above, according to the multimedia minutes creating method and system of the present invention, a speaker is specified, and unique information such as the speaker's name is added to the content of the speech (voice information or character information). ) By using a digital watermark technology (the unique information may be directly embedded), it becomes impossible to deny the content of what the speaker himself said.

Further, according to the present invention, various methods and combinations can be selected at the time of creating the minutes. Therefore, if the user wants to leave it as a document, the minutes represented by character information can be printed. Good. Further, when it is desired to display it on the screen, the character information can be arranged and displayed at a position on the screen. Further, when it is desired to output the minutes by voice, the minutes represented by the voice information can be output from a speaker or the like.

Further, by the digital watermark technique, the contents of the utterance can be seen, but the unique information cannot be seen at the speaker's video conference terminal.
When the minutes are generated by voice information and the digital watermark technology is not applied to the voice information, the speaker's name is directly embedded in the voice information so that the speaker can speak Therefore, the content of the statement cannot be denied based on the name.
