  FIG. 9 is a block diagram illustrating a configuration example of a communication system described in Patent Document 1. In FIG. The communication terminal 910 is connected to the presence service providing server 920 via the network 930. The communication terminal 910 includes a communication unit 911 that enables connection to the network 930, an information storage unit 912 that can store programs and various information, a display unit 913 that can display information, and text input. Character input means 914 that enables voice input, voice input means 915 that enables voice input, voice output means 916 that enables voice output, and can capture images such as still images and moving images Imaging means 917 and processing means 918 for performing various information processing and operation control. The presence service providing server 920 includes a communication unit 921 that enables connection to the network 930, a server-side information storage unit 922 that stores user information related to a user who uses the presence service, and various information processing and operation control. The processing means 923 for performing the above is provided. The communication terminal 910 exchanges the presence of a still image, a character string, or a moving image via the presence service providing server 920.

  However, the method described in Patent Document 1 only controls whether or not to display telepresence depending on the other party. For this reason, the means and quality of telepresence cannot be changed depending on the status of the other party, his / her presence, and the device used by the other party. As shown in FIG. 9, the only way to grasp the situation of the other party is based on multimedia telepresence. Therefore, based on the normal presence, the quality of telepresence cannot be adjusted according to the other party, his / her work situation, or the other party's device situation. Originally, telepresence and normal presence are not competing, but can be linked. For example, when both of the set normal presences are in a call, whether or not to communicate the telepresence of a moving image depends on the relationship with the other party, but the method described in Patent Document 1 Fine control of telepresence linked with presence is not possible. In addition, depending on the partner device, it is necessary to change the type of telepresence. For example, in the case of access from outside the company, information may be leaked due to loss of in-house video due to moving images or sound reproduction by speakers, so the type of telepresence needs to be changed.

  Therefore, the conventional methods or means have the following problems.

  The first problem is that control linked to the normal presence of both the user and the partner cannot be performed. The reason is that only the type of telepresence for each transmission partner can be set, and there is no function for switching the telepresence based on the normal presence of both itself and the partner in detail.

  A second problem is that telepresence transmission control depending on the device used by the other party cannot be performed. The reason is that telepresence cannot be controlled depending on the situation of the other party.

  Therefore, the present invention can realize a multimedia telepresence that is efficient in accordance with the situation of the other party and itself by controlling the telepresence in detail based on the normal presence information of both the other party and the other party. An object of the present invention is to provide a presence exchange terminal, a presence exchange method, and a presence exchange program.

  Also, a presence exchange terminal, presence exchange method, and presence exchange that enable multimedia telepresence display to prevent information leakage by further controlling the means and quality of multimedia telepresence according to the device status of the other party The purpose is to provide a program.

The telepresence means determined by the telepresence quality requesting means based on the normal presence is further narrowed down by the telepresence means determined by (1).

  According to the present invention, there is an effect that it is possible to perform control linked to the normal presence of both the user and the partner. The reason is that the presence exchange terminal device according to the present invention includes a telepresence quality adjusting means based on the normal presence, and the normal presence of the telepresence transmission destination and the presence set by the terminal itself are indicated by the normal correspondence table indicated by the transmission partner correspondence table. This is because the telepresence means determined by the presence-corresponding pattern has a function of switching telepresence in detail based on the normal presence of both itself and the other party by exchanging telepresence.

  Further, according to the present invention, there is an effect that transmission control of telepresence can be performed depending on a device used by the other party. The reason is that the presence exchange terminal device has a telepresence quality adjustment means by the counterpart device, and is based on the normal presence of the telepresence destination and the telepresence means determined by the counterpart device correspondence pattern indicated by the counterpart correspondence table. This is because, by further narrowing down the telepresence means determined by the telepresence quality requesting means based on normal presence, the telepresence is controlled according to the situation of the other party.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a communication system including a presence exchange terminal device (terminal device) according to the present invention. The communication system shown in FIG. 1 includes a normal presence exchange server 1 and a plurality of terminal devices 10. Each terminal device 10 includes telepresence quality adjusting means 20.

  The terminal device 10 is connected to and communicates with another terminal device 10 and the normal presence exchange server 1 via a network.

  The normal presence exchange server 1 is an existing presence server, and manages the presence of character strings such as, for example, the presence / absence / separation of a user, during a call, during capture, and during a conference. “Presence” refers to the state of the user such as the user's presence, absence, absence, call, taking in, and meeting.

  The terminal device 10 registers its normal presence information in the normal presence exchange server 1. Further, the terminal device 10 acquires (receives) normal presence information of the terminal device 10 of another user from the normal presence exchange server 1 and displays it.

  The telepresence quality adjustment means 20 performs multimedia telepresence such as video, audio, still image, etc. in addition to normal presence, normal presence on both the transmission side and reception side, device information on the reception side, and call status on the transmission side Select and communicate according to Note that “telepresence” refers to media used in multimedia such as moving images, sounds, and still images.

  Next, the configuration of the presence exchange terminal device according to the present invention will be described with reference to the drawings. FIG. 2 is a block diagram showing a configuration example of a presence exchange terminal device (terminal device) according to the present invention. The terminal device shown in FIG. 2 includes a terminal input / output device 100, a terminal processing device 200, and a terminal storage device 300, which are combined to form one terminal device 10 (see FIG. 1). The terminal input / output device 100, the terminal processing device 200, and the terminal storage device 300 are connected to and communicate with other terminal devices and the normal presence exchange server 1 via networks.

  The terminal input device 100 includes a normal presence setting unit 101, a confidentiality setting unit 102, a telepresence input unit 103, and a telepresence output unit 104.

  The normal presence setting means 101 is a general presence setting means for setting the presence of a character string of its own terminal device. The normal presence setting means 101 sets character string information such as being present, absent, away from the telephone, busy, taking in, and meeting as the normal presence, and notifies (transmits) to the normal presence exchange server 1. At this time, as shown in FIG. 3, the IP address of the terminal itself and the audio output device information indicating whether the speaker or the headset is used are simultaneously sent (transmitted) to the normal presence exchange server 1.

  FIG. 3 is an explanatory diagram showing an example of normal presence information. As shown in FIG. 3, the presence information is information including information indicating normal presence, information indicating an IP address, and audio output device information.

  The normal presence setting unit 101 transmits normal presence information to the normal presence exchange server 1. At the same time, the normal presence setting unit 101 notifies (transmits) its normal presence information to a telepresence quality adjustment unit 202 based on normal presence, which will be described later, in the terminal processing device 200 of the normal presence.

  The confidentiality setting means 102 sets the confidentiality (confidential level) during a call. FIG. 4 is an explanatory diagram showing an example of the confidential level set by the confidentiality setting means 102. The confidentiality setting means 102 sets the numerical value shown in FIG. 4 as the confidential level. The security level is information for narrowing down usable media. For example, as shown in FIG. 4, it is possible to set the confidential level 2 so that still images and moving images can be transmitted by telepresence, but audio cannot be transmitted by telepresence. By setting the confidentiality level, it is possible to select the information that the telepresence recipient does not want to hear and the information that the telepresence recipient does not want to show according to the content of the call. The available media narrowing information (security level) set here is transmitted to the telepresence quality adjusting means 204 based on the telephone density described later in the terminal processing apparatus 200.

  The telepresence input unit 103 is a device such as a camera or a microphone that inputs multimedia information (telepresence information) such as moving images, still images, and sounds. The input multimedia information is sent to a telepresence transmission unit 205 for each transmission partner described later. The telepresence information is media data such as moving images, sounds, and still images.

  Telepresence output means 104 outputs telepresence information sent from another terminal device. The telepresence output unit 104 is realized by, for example, a display device such as a monitor that displays a screen, a headset, or a speaker, and outputs telepresence information.

  Next, the terminal processing apparatus 200 will be described. The terminal processing device 200 includes a normal presence acquisition unit 201, a telepresence quality adjustment unit 202 based on normal presence, a telepresence quality adjustment unit 203 based on a partner device, a telepresence quality adjustment unit 204 based on a telephone density, and a transmission partner. Telepresence transmission means 205, telepresence communication means 206, and telepresence reception / combination means 207. Telepresence quality adjusting means 202 based on normal presence, telepresence quality adjusting means 203 based on the partner device, and telepresence quality adjusting means 204 based on telephone density correspond to telepresence quality adjusting means 20 (see FIG. 1).

  The telepresence acquisition unit 201 acquires information indicating the other party's normal presence, information indicating the IP address, and voice output device information from the normal presence exchange server 1 as normal presence information of the telepresence transmission partner. It is stored as normal presence information 301 of a transmission destination described later in the terminal storage device 300.

  The telepresence quality adjusting means 202 based on the normal presence narrows down which medium transmits the telepresence information from its own normal presence and the normal presence of the telepresence transmission partner.

  The telepresence quality adjustment unit 202 based on normal presence receives the normal presence (see FIG. 3) of the telepresence transmission destination acquired (extracted) from the normal presence information 301 of the transmission destination described later, and the own presence received from the normal presence setting unit 101. Based on the normal presence (see FIG. 3), the number of the presence correspondence table is retrieved from the transmission partner correspondence table stored in the transmission partner correspondence table storage unit 304 described later based on the information indicating the transmission partner. Then, the telepresence quality adjusting means 202 based on the normal presence acquires (extracts) the normal presence corresponding pattern stored in the normal presence corresponding pattern storage means 303 described later from the corresponding corresponding number. Further, the telepresence quality adjusting means 202 based on normal presence determines the telepresence medium to be transmitted from the extracted normal presence corresponding pattern. FIG. 5 is an explanatory diagram illustrating an example of a transmission partner correspondence table. FIG. 6 is an explanatory diagram showing an example of a normal presence correspondence pattern.

  In the normal presence support pattern, for example, for each telepresence medium such as voice, video, and still image, a correspondence table between the normal presence of the terminal and the normal presence of the telepresence destination terminal is described. Yes. It is possible to indicate levels such as “x” that does not transmit the telepresence of the corresponding media, “○” that transmits telepresence, “◎” that transmits high-definition telepresence, etc. Not only × ○ ◎, but also the resolution and frame rate can be set in detail.

  The information indicating the telepresence medium for which “○”, “◎”, etc. are set in the normal presence corresponding pattern shown in FIG. 6 and transmission is permitted is then sent to the telepresence quality adjusting means 203 by the counterpart device. .

  The telepresence quality adjustment means 203 by the counterpart device is information indicating the telepresence medium sent from the telepresence quality adjustment means 202 by the normal presence based on the device information (voice output device information) used by the counterpart device. Narrow down again.

  The telepresence quality adjustment means 203 by the partner device is described later based on the telepresence destination IP address and voice output device information (see FIG. 3) acquired (extracted) from the normal presence information 301 of the destination described later. The number of the device correspondence table is searched from the transmission partner correspondence table (see FIG. 5) stored in the transmission partner correspondence table storage means 304 to be based on the information indicating the transmission partner. Then, the telepresence transmitting terminal acquires (extracts) the counterpart device correspondence pattern stored in the counterpart device correspondence pattern storage means 302 described later from the corresponding correspondence number.

  FIG. 7 is an explanatory diagram showing an example of a partner device correspondence pattern. As shown in FIG. 7, the partner device correspondence pattern is information indicating whether or not transmission of a predetermined telepresence medium associated with the reproduction medium and the personal computer of the transmission partner is possible. In the pattern corresponding to the partner device shown in FIG. 7, information (sound output device information) indicating a playback device indicating whether the speaker is a headset or a headset with respect to the sound, with respect to information indicating a telepresence medium such as a sound, a moving image, and a still image. In addition, it is a medium for playback. FIG. 7 illustrates a case where audio (speaker), audio (headset), moving image, and still image are used as a reproduction medium.

  A personal computer (for example, an external PC, an out-of-room PC, an in-room PC, or a home PC) as a transmission partner in the partner device corresponding pattern is determined from the IP address of the transmission partner. As illustrated in FIG. 7, the partner device corresponding pattern is a table (table data) that indicates by which personal computer each playback medium can be played back by ○ or ×.

  For example, a case where the information indicating the telepresence medium is information indicating that voice can be transmitted will be described. The telepresence quality adjusting means 203 by the partner device acquires (extracts) whether it is a speaker or a headset from the audio output device information, and specifies a reproduction medium. The telepresence quality adjustment means 203 by the partner device executes a predetermined look-up process (search for the partner device corresponding pattern) process based on the information indicating the specified reproduction medium and the information indicating the personal computer of the transmission partner. If the search result is x, the audio is excluded from the transmission media. When both the speaker and the headset are in a reproducible state, if either of the search results corresponding to “voice (speaker)” and “voice (headset)” is x, the voice is excluded.

  The telepresence quality adjustment means 203 by the partner device narrows down the telepresence media to be transmitted, so that fine transmission control is possible depending on the location of the partner personal computer, for example, and information to the outside by multimedia telepresence transmission Leakage can be prevented. Information indicating the narrowed telepresence media is sent to the telepresence quality adjusting means 204 based on the telephone density.

  The telepresence quality adjusting means 204 based on the telephone density is sent from the telepresence quality adjusting means 203 by the partner device based on the confidentiality specified by the user of the terminal that is transmitting the telepresence according to the content of the call. Narrow down the telepresence media again.

  The telepresence quality adjusting means 204 based on the telephone density is used to narrow down the telepresence media that can be transmitted based on the density specified by the density setting means 102 (see FIG. 4). The higher the sensitivity, the less media available. By narrowing down, it is possible to easily narrow down telepresence according to the contents of calls and work, and it is possible to reduce the psychological barrier caused by constantly transmitting information.

  In a series of processes performed by the telepresence quality adjusting means 202 based on normal presence, the telepresence quality adjusting means 203 based on the other party device, and the telepresence quality adjusting means 204 based on the telephone density, the telepresence that can be transmitted is determined for each transmission destination. The media is finalized. The telepresence quality adjusting unit 204 based on the telephone density transmits information indicating the confirmed telepresence medium to the telepresence transmitting unit 205 for each transmission partner.

  The telepresence transmission unit 205 for each transmission partner is information indicating the telepresence available media for each transmission partner sent from the telepresence quality adjustment unit 204 based on the telephone density regarding the telepresence sent from the telepresence input unit 103. The media data (telepresence information) to be transmitted is controlled based on. The telepresence transmission unit 205 for each transmission partner sends information indicating the transmission partner and telepresence information to the presence communication unit 206 if transmission is possible.

  The presence communication unit 206 transmits telepresence information to another terminal device used by the transmission partner in accordance with the information indicating the transmission partner sent from the telepresence transmission unit 205 for each transmission partner.

  Conversely, when telepresence information is received from another terminal, the presence communication unit 206 sends the received telepresence information to the telepresence reception / combination unit 207.

  The telepresence receiving / combining unit 207 combines the telepresence information received from the telepresence communication unit 206 for each transmission source terminal. The telepresence receiving / synthesizing unit 207 performs mixing if the telepresence is a voice, and if it is a moving image or a still image, the region is divided and converted into a format for output to the screen, and sent to the telepresence output unit 104 .

  The terminal storage device 300 stores the normal presence information 301 of the transmission destination, and includes counterpart device correspondence pattern storage means 302, normal presence correspondence pattern storage means 303, and transmission counterpart correspondence table storage means 304.

  The normal presence information 301 of the transmission destination is information including the normal presence, the IP address, and the voice output device information (see FIG. 3) sent from the normal presence acquisition unit 201. The normal presence information 301 of the transmission destination is written when the other party logs in to the normal presence exchange server 1 and registers the presence information, and is erased when logging out.

  The counterpart device correspondence pattern storage means 302 stores the counterpart device correspondence pattern. The partner device corresponding pattern stores information indicating in which location a personal computer permits or does not allow telepresence transmission for each reproduction medium.

  The counterpart device correspondence pattern storage means 302 stores, for example, a plurality of counterpart device correspondence patterns, each of which is assigned a unique number and managed. A plurality of counterpart device correspondence patterns are registered in advance by the setter or the user of the terminal device, and are statically determined when the terminal is activated.

  The normal presence corresponding pattern storage unit 303 stores a normal presence corresponding pattern. The normal presence corresponding pattern is a two-dimensional table of the normal presence of the telepresence transmission destination and the normal presence of the telepresence transmission partner for each telepresence medium such as voice, moving image, and still image.

  The normal presence corresponding pattern is, for example, information indicating whether each medium can transmit telepresence information associated with its own normal presence and the normal presence of the telepresence transmission partner. The normal presence corresponding pattern may be information indicating a medium that can transmit telepresence information in association with its normal presence and the normal presence of the telepresence transmission partner, for example.

  In the normal presence correspondence pattern, “◯” is set when a predetermined medium can transmit telepresence information, “X” is set when transmission is impossible, and “◎” is set when transmission is possible with high quality. Depending on the type of telepresence, quality can be specified numerically. For example, if you are ingestion and the other party is present, you can specify that you want to send a high-quality video, and if you are away and the other party is away, You can also specify that only still images are sent. In addition, a moving image is transmitted to a partner with a high degree of intimacy in any case, but only during a call can be specified to switch to a still image because it becomes heavy (slow processing) if the moving image is transmitted.

  For example, a unique number is assigned to the normal presence corresponding pattern. A plurality of normal presence corresponding patterns are registered in advance by the setter or the user of the terminal device, and are statically determined when the terminal is activated. A plurality of normal presence corresponding patterns are stored in the normal presence corresponding pattern storage means 303.

  The transmission partner correspondence table storage unit 304 stores a correspondence table (transmission partner correspondence table) for each transmission partner. As shown in FIG. 5, in the transmission partner correspondence table, a “presence correspondence table” in which a number indicating a normal presence correspondence pattern is set in association with the transmission partner, and a partner device correspondence pattern in association with the transmission partner in the same manner. A “device correspondence table” in which a number indicating “” is set is stored. That is, in the “presence correspondence table”, a number indicating which user uses which normal presence correspondence pattern is registered. In the “device correspondence table”, a number indicating which user uses which partner device correspondence pattern is registered.

  The transmission partner correspondence table is registered, for example, by a user or a setter of the terminal device. Since it is easy to set or change the normal presence correspondence pattern or the counterpart device correspondence pattern depending on the other party, fine telepresence control can be performed for each user.

  The terminal device can be realized by a computer, and each component constituting the terminal processing device 200 can be realized as a program for causing the processing device (CPU) of the computer to realize the functions described above.

  Next, the operation of the present embodiment will be described with reference to the drawings. FIG. 8 is a flowchart showing the operation of the present embodiment.

  A description will be given on the assumption that a telepresence transmitting terminal and a telepresence receiving terminal exist as terminal devices. The configuration of the telepresence transmitting terminal and the telepresence receiving terminal is the same as that of the terminal device 10. The processing in steps S101 to S110 is processing performed by the telepresence transmission terminal. Steps S201 to S205 are processes performed by the telepresence receiving terminal.

  In step S101, the telepresence transmitting terminal performs normal presence setting. In step S201, the telepresence receiving terminal sets the normal presence.

  Next, in step S202, the telepresence receiving terminal transmits the normal presence, its own IP address and voice output device information to the normal presence exchange server 1.

  The telepresence transmitting terminal receives the normal presence information transmitted by the telepresence receiving terminal in step S202 from the normal presence exchange server 1 (step S102). In step S103, the telepresence transmitting terminal extracts the IP address and the voice output device information from the received normal presence information, and stores them as the normal presence information 301 of the transmission destination.

  In step S104, the telepresence transmitting terminal narrows down telepresence by normal presence. The telepresence transmitting terminal narrows down which media transmits the telepresence information from its own normal presence and the normal presence of the telepresence information transmission partner.

  The telepresence transmission terminal obtains (extracts) the normal presence of the telepresence transmission destination (see FIG. 3) acquired from the normal presence information 301 of the transmission destination and the normal presence of the telepresence transmission terminal received from the normal presence setting means 101 (see FIG. 3). ), The number of the presence correspondence table is retrieved from the transmission partner correspondence table (see FIG. 5) stored in the transmission partner correspondence table storage unit 304 based on the information indicating the transmission partner. Then, the telepresence transmitting terminal acquires (extracts) the normal presence corresponding pattern (see FIG. 6) stored in the normal presence corresponding pattern storage means 303 from the corresponding corresponding number. Further, a medium that can transmit telepresence information is determined from the extracted normal presence corresponding pattern.

  In the normal presence support pattern, for example, for each telepresence medium such as voice, video, and still image, a correspondence table between the normal presence of the terminal and the normal presence of the telepresence destination terminal is described. Yes. It is possible to indicate levels such as “x” that does not transmit the telepresence of the corresponding media, “○” that transmits telepresence, “◎” that transmits high-definition telepresence, etc. Not only × ○ ◎, but also the resolution and frame rate can be set in detail.

  Next, in step S105, the telepresence transmitting terminal narrows down telepresence again based on the other playback device.

  The telepresence transmission terminal stores the transmission destination correspondence table storage unit 304 based on the telepresence transmission destination IP address and voice output device information (see FIG. 3) acquired (extracted) from the normal presence information 301 of the transmission destination. The number of the device correspondence table is searched from the stored transmission partner correspondence table (see FIG. 5) based on the information indicating the transmission partner. Then, the telepresence transmitting terminal acquires (extracts) the counterpart device correspondence pattern (see FIG. 7) stored in the counterpart device correspondence pattern storage means 302 from the corresponding correspondence number.

  In the pattern corresponding to the partner device shown in FIG. 7, information (sound output device information) indicating a playback device indicating whether the speaker is a headset or a headset with respect to the sound, with respect to information indicating a telepresence medium such as a sound, a moving image, and a still image. In addition, it is a medium for playback. FIG. 7 illustrates a case where audio (speaker), audio (headset), moving image, and still image are used as a reproduction medium.

  A personal computer (for example, an external PC, an out-of-room PC, an in-room PC, or a home PC) as a transmission partner in the partner device corresponding pattern is determined from the IP address of the transmission partner. As illustrated in FIG. 7, the partner device corresponding pattern is a table (table data) that indicates by which personal computer each playback medium can be played back by ○ or ×.

  For example, a case where the information indicating the telepresence media data is information indicating that voice can be transmitted will be described. The telepresence transmission terminal acquires (extracts) whether it is a speaker or a headset from the audio output device information, and specifies a reproduction medium. The telepresence transmitting terminal executes a predetermined look-up process (search for the partner device-corresponding pattern) process based on the information indicating the specified reproduction medium and the information indicating the personal computer of the transmission partner. If the search result is x, the audio is excluded from the transmission media. When both the speaker and the headset are in a reproducible state, if either of the search results corresponding to “voice (speaker)” and “voice (headset)” is x, the voice is excluded.

  When the telepresence transmission terminal narrows down the telepresence media to be transmitted, for example, fine transmission control according to the location of the partner personal computer can be performed.

  Next, in step S106, the telepresence transmission terminal narrows down the telepresence again by setting the confidentiality. The available media are narrowed down according to the sensitivity setting of the telepresence information transmission terminal. If the content of a call or work is a content that you want to suppress transmission beyond the settings of the normal presence-compatible pattern and the counterpart device-compatible pattern, increase the sensitivity so that detailed telepresence information is not transmitted. It becomes possible to do.

  Next, in step S107, the telepresence transmitting terminal acquires telepresence. In step S108, the telepresence transmitting terminal starts transmitting telepresence media data (telepresence information) designated for each transmission partner.

  At the same time, the telepresence receiving terminal starts receiving telepresence in step S203. In step S204, the telepresence receiving terminal starts outputting telepresence information by playing and displaying telepresence.

  In step S109, when the confidentiality is changed, the telepresence transmitting terminal shifts the control to step S106 and narrows down the telepresence by setting the confidentiality again.

  When the normal presence is changed in step S110 and step S205, control is transferred to step S101 and step S201, and the process is reproduced from the beginning. In step S110, when the normal presence of the telepresence transmitting terminal is changed, the process is started from step S101. If the normal presence of the telepresence receiving terminal is changed in step S205, the processing of the telepresence transmitting terminal is started from step S102 through step S201 and step S202.

  Next, the effect of this embodiment will be described. In the present embodiment, the terminal device includes a telepresence quality adjustment unit based on normal presence, and the normal presence corresponding to the presence of the telepresence information transmission destination and the presence set by the terminal itself is indicated by the transmission partner correspondence table. Telepresence information is exchanged by the telepresence means (media) determined by the pattern. Therefore, by having a function of switching in detail the telepresence based on the normal presence of both the self and the other party, it is possible to perform control linked to the normal presence of both the self and the other party.

  In the form of the present invention, the terminal device further includes a telepresence quality adjusting unit by the partner device, and the telepresence unit determined by the normal presence of the telepresence transmission destination and the partner device correspondence pattern indicated by the transmission partner correspondence table (Media) further narrows down the telepresence means determined by the telepresence quality adjustment means based on normal presence. Therefore, by controlling the telepresence according to the other party's situation, transmission control of telepresence information depending on the device used by the other party can be performed.

  INDUSTRIAL APPLICABILITY The present invention can be effectively applied in a communication system such as an IP telephone and a web conference by appropriately transmitting a presence without excess or deficiency to notify a partner's situation and grasp the situation. The presence of the other party can be confirmed in detail by multimedia telepresence, and the transmission range can be narrowed down by the presence of the normal character string of the other party and the other party's output device, and leakage of confidential information due to abundant presence information The multimedia can be automatically selected according to the other party, his / her situation and the other party's location.
