Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
(First embodiment)
FIG. 1 is a diagram showing an outline for explaining a network system (IP telephone system) according to an embodiment of the present invention. The network system (IP telephone system 10) shown in FIG. 1 includes a network (IP network 12), a plurality of devices (computer 40, door phone 50, IP telephone 60) connected to the network, and commands between the plurality of devices. And a control means (conversion table server 100) for controlling the transmission / reception, and the control means replaces a function (operation) in each device with a function (operation) in another device.

  In the IP telephone system 10 of the present embodiment, a plurality of IP networks 12 and 13 are connected via the IP-VPN 11. In the first IP network 12, a switching hub 22 is connected to the router 21, and the switching hub 22 includes a plurality of devices (computer 40, door phone 50, IP telephone 60, IP-PBX 80, voice recognition server 90, A conversion table server 100) is connected. The router 21, the switching hub 22, and each device (computer 40, door phone 50, IP telephone 60, IP-PBX 80, voice recognition server 90, conversion table server 100) constitute a LAN.

  The computer 40 processes information received from the IP network 12 and information input via the keyboard 41 and other interfaces and displays the processed information on the display unit 42 and outputs various processed information to the IP network 12. To do. When the call button 51 provided on the housing is pressed, the door phone 50 reads, for example, a reception group of a predetermined extension number (for example, extension number 100) from a table stored in the door phone 50, Place a call with the reception group as the destination. The reception group may be stored in a server on the network instead of being stored in the door phone 50, and the server may be referred to. As a result, the act of pressing the push button 51 of the door phone 50 is an operation of calling a predefined extension (for example, No. 100) group. In the conversion table server 100 to be described later, this call signal is replaced with a function (operation) corresponding to the transmission source (door phone 50) and transmission destination (IP telephone 60). Note that the replacement of the function (operation) is not limited to simply replacing the command, but is a concept including replacement of the function or operation of a device (computer 40, door phone 50, IP telephone 60) connected to the IP network 12. is there. The function replacement in the conversion table server 100 will be described later. Each IP telephone 60 is connected to the IP network 12 via the access point 70, and sends the voice input via the microphone 61 provided in the IP telephone 60 to the IP network as voice data. At the same time, the audio data received from the IP network is output as audio from the speaker 62.

  The IP-PBX 80 is connected to each device (computer 40, door phone 50, IP phone 60, voice recognition server 90, conversion table server 100) in the IP network, and the connection between the IP phones 60 or the IP phone 60 and other devices. Connection with the computer 40, the door phone 50, etc. is performed via the voice recognition server 90 and the conversion table server 100. That is, the IP-PBX 80 transmits information (including commands) transmitted from devices such as the computer 40, the door phone 50, and the IP telephone 60 to the conversion table server 100 once regardless of the destination. A command in which a command change described later is performed is received and transmitted to the destination device.

  The voice recognition server 90 receives voice data input from the microphone 52 provided in the door phone 50 or voice input means of the computer 40 (for example, an external microphone (not shown) connected to a USB terminal) via the IP network 12. And the meaning of the voice is recognized based on the voice data.

  The conversion table server (IP telephone conversion device) 100 performs conversion for associating the function (operation) of the IP telephone 60 with the functions (operations) of other devices (computer 40, door phone 50, IP telephone 60). It has a table and has a function of converting various commands output from each device (computer 40, door phone 50, IP telephone 60) according to the transmission source device and the destination device. Here, the command conversion is not limited to simply converting one command into another command, but it means that the function (operation) is converted, such as conversion into a plurality of commands. Thus, for example, when a call is made from the door phone 50, the call button 51 functions as a button for making a call to a preset extension reception group. When an incoming call is made to the door phone 50, a ringing sound is generated in the door phone 50, and the call button 51 is pressed, so that an operation corresponding to an off-hook operation in the telephone can be defined. Thereby, even for the same call button 51, different meanings can be defined for outgoing calls and incoming calls. Furthermore, by defining the meaning of the call button 51 during a call (during conversation) in addition to the definition based on the transmission source and the destination, further different meanings can be defined. In the present embodiment, a case will be described in which the conversion table server 100 is provided on the IP network 12 independently of each device (computer 40, door phone 50, IP telephone 60). However, the present invention is not limited to this, and each apparatus computer 40, door phone 50, IP telephone 60) may be provided.

  In the IP telephone system 10, a second IP network 13 having the same configuration as that of the first IP network 12 is connected to the IP-VPN 11. The devices of the second IP network 13 are of the same type as the devices of the first IP network 12 (computer 40, door phone 50, IP telephone 60, IP-PBX 80, voice recognition server 90, conversion table server 100). The same reference numerals are assigned to the respective devices, and duplicate descriptions thereof are omitted.

  As described above, since the plurality of IP networks 12 and 13 are connected via the IP-VPN 11, information can be exchanged not only within one IP network but also with other IP network devices. It is possible to do.

  The CPU 53 is activated by an activation program stored in the ROM 54, and executes various programs while using the RAM 55 as a work memory. In the program execution process, the CPU 53 processes signals supplied from the call button 51, the camera 58, and the microphone 52 and outputs various audio signals by outputting audio signals to the speaker 53. Audio input via the microphone 52 is stored in the RAM 45 as audio data. The camera 58 is an image pickup unit having a CCD image pickup device or the like, for example, and the picked up image signal is stored in the RAM 45. The communication interface 59 is an interface for transmitting / receiving various data to / from the IP network 12. Audio data received from the IP network 12 is output from the speaker 53 as audio. The door phone 50 is configured to establish a connection with another device (computer 40, IP telephone 60, etc.) by the IP-PBX 80.

  As shown in FIG. 4, the IP telephone 60 includes a bus B3, a CPU 63, a ROM 64, a RAM 65, an input key 66, an LCD configuration display unit 67, a microphone 61, a speaker 62, a camera 68 connected to the bus B3. And a communication interface 69.

  The CPU 63 is activated by the activation program stored in the ROM 64, and executes various programs while using the RAM 65 as a work memory. In the program execution process, the CPU 63 processes signals supplied from the input key 66, the camera 68, and the microphone 61. The CPU 63 outputs an audio signal to the speaker 62 and outputs an image signal to the display unit 67, thereby outputting various sounds from the speaker 62 and displaying an image on the display unit 67. The sound input via the microphone 61 is stored in the RAM 65 as sound data. The camera 68 is an imaging unit having, for example, a CCD imaging device, and the captured image signal is stored in the RAM 65. The input key 66 includes a plurality of operation keys such as numeric keys, off-hook keys, and on-hook keys. The communication interface 69 is an interface for transmitting / receiving various data to / from the IP network 12 via the access point 70 by wireless communication. Audio data received from the IP network 12 is output as audio from the speaker 62. The IP telephone 60 is configured to establish a connection with another device (computer 40, door phone 50, etc.) by the IP-PBX 80.

  On the other hand, the voice recognition server 90 includes a storage unit and a communication interface for performing communication with the IP network 12, and a voice recognition program is stored in the storage unit. The voice recognition server 90 recognizes the meaning of voice data transmitted from the IP network by executing a voice recognition program stored in the storage unit.

  The conversion table server 100 includes a storage unit and a communication interface for performing communication with the IP network 12, and the storage unit includes each device (computer 40, door phone) connected to the IP network 12. 50, IP telephone 60, etc.), a conversion table for associating commands (functions), an address (IP address) assigned to each device and the type of device to which the address is assigned (eg, IP phone, door phone) , A type of computer or the like) and a program for associating commands (functions).

  The conversion table server 100 is sent from each device (computer 40, door phone 50, IP telephone 60, etc.) connected to the IP network 12 by executing a conversion program stored in the storage unit. The command is converted into a command for executing a function according to the destination device and transmitted to the destination device. Here, the command represents a command output in response to a user operation or the like in each device. For example, when the call button 51 is pressed on the door phone 50, the “call button press operation” is output from the door phone 50. A command representing a “processing instruction corresponding to” is transmitted to the IP network 12. In the IP network 12, the command is received by the conversion table server 100, and the conversion table server 100 converts the command according to the destination address.

  In the case of the present embodiment, the destination address in the IP network 12 is specified by the description of the IP address derived by the DHCP server (not shown). Here, based on the correspondence table, when it is found that the device of the destination address is, for example, the IP phone 60, the conversion table server 100 outputs from the door phone 50 by referring to the conversion table stored in the storage unit. The command representing the “processing instruction corresponding to the pressing operation of the call button” is converted into a command indicating the “processing instruction corresponding to the pressing operation of the off-hook key” in the IP telephone 60. The command converted in accordance with the destination device is transmitted to the IP telephone 60 that is the destination, so that the IP telephone 60 that has received the converted command uses the door phone 50 that is the message transmission source. Thus, it can be determined that the “off-hook key has been pressed” by comparing the operation result of the IP telephone 60.

  That is, although it is difficult for IP phone 60 to originally determine a command according to the operation result of door phone 50, door table 50 is converted to a command replaced with an operation on IP phone 60 by conversion table 101. The operation result can be determined. In this case, in the conversion table, among the user operations on each device, operations having the same meaning (purpose) are associated with each other. That is, the operation result of the user on the door phone 50 is converted into the operation result for the same purpose of the user on the IP phone 60. For example, in the door phone 50, the operation of “pressing the call button 51” represents the purpose of transmitting the presence of the person to the person inside the door through the door phone 50 and transmitting some message. If replaced with an operation, it can be replaced with an operation of “pressing the off-hook key of the IP telephone 60 to make a call”. That is, by using the conversion table, command conversion is performed between different devices so that the user's operation purpose is the same. That is, by such conversion, the call button 51 of the door phone 50 functions as a call button. On the other hand, as shown in FIG. 5B described later, when the transmission source is the IP telephone 60 and the destination is the door phone 50, a telephone number is input to the door phone 50 in the IP telephone 60. (When registered in advance, only a specific key is operated) When a call is made, this operation is converted into a function of outputting a ringing tone in the doorphone 50 in the conversion table 101, and the doorphone 50 is called in this state. The pressing operation of the button 51 is replaced with an operation result of off-hook similar to the operation of the IP telephone 60. By defining such replacement of functions in accordance with the transmission source, destination, and operation state in the conversion table 101, for example, the call button 51 of the door phone 50 not only functions as a call button but also an off-hook button when a call is received Will function as. Thus, the conversion table server 100 not only converts one command but also replaces a function (operation) including a plurality of commands.

  FIG. 5A is a diagram illustrating an example of a conversion table stored in the storage unit of the conversion table server 100. As shown in FIG. 5, in this conversion table 101, a command representing “a processing instruction corresponding to a pressing operation of the numeric key“ 1 ”” as a command in the IP telephone 60 is sent via the keyboard 41 of the computer 40. A command representing “a processing command corresponding to the pressing operation of the numeric key“ 1 ”” as an input command, and a “processing command corresponding to a speech recognition result“ 1 ”of the input speech as an input command via the voice interface 47 in the computer 40 Is associated with a command representing “a processing command corresponding to the speech recognition result“ 1 ”of the input speech” as an input command via the microphone 52 in the door phone 50. As a result, when the numeric key “1” on the keyboard 41 of the computer 40 is pressed, a command representing a processing instruction corresponding to the operation result is pressed by the “numeric key“ 1 ”of the IP telephone 60 by the conversion table 101. When the voice “1” is input through the microphone connected to the voice interface 47 of the computer 40, the processing command corresponding to the input result is converted into a command representing the “processing command when operated”. The command to be converted is converted into a command indicating “a processing instruction when the numeric key“ 1 ”is pressed” of the IP telephone set 60 by the conversion table 101, and the voice “1” is output via the microphone 52 of the door phone 50. When input, a command representing a processing instruction corresponding to the input result is displayed by the conversion table 101 as I The telephone 60 is converted to a command representing a "numeric key" 1 "is processing instructions when it is pressed."

  In addition, in this conversion table 101, “function key press” is input as an input command via the keyboard 41 of the computer 40 with respect to a command representing “processing instruction corresponding to an off-hook key press operation” as a command in the IP telephone 60. A command representing a “processing command according to operation”, a command representing a “processing command according to a person image photographing result” as an input command via the camera 48 in the computer 40, and an input via the call button 51 in the door phone 50. The command is associated with a command representing “a processing command corresponding to the pressing operation of the call button”. As a result, when it is determined that the image captured by the camera 48 of the computer 40 is a person image by the image processing of the computer 40, a command representing a processing command corresponding to the imaging result is transmitted to the IP by the conversion table 101. When the telephone 60 is converted into a command indicating “a processing instruction when the off-hook key is pressed” and the call button 51 of the door phone 50 is pressed, a command indicating a processing command corresponding to the operation result is The conversion table 101 converts the IP telephone 60 into a command representing the “processing instruction when the off-hook key is pressed”.

  FIG. 6 is a flowchart showing a command conversion processing procedure in the conversion table server 100. In FIG. 6, the case of simply replacing a command will be described. However, the present invention is not limited to this, and the present invention replaces (converts) a function (operation) including assignment of a plurality of commands. It also includes things. As shown in FIG. 6, the conversion table server 100 waits for input of a command from a device connected to the IP network 12 in step ST11. When a command is input from any of the devices, the conversion table server 100 obtains an affirmative result in step ST12, thereby moving from step ST12 to step ST13 to determine the source and destination of the input command. Judgment is made from the source address and the destination address (IP address). Incidentally, in each device, when a command is generated according to an input operation or the like by the user, a destination address is determined in the transmission source device according to the input mode. For example, in an input mode in which the call button 51 is pressed on the door phone 50, a destination address of a command generated according to the input mode is determined in advance in the device. The destination address may be set in the IP-BPX 80 or the conversion table server 100.

  Further, the destination address can be determined by the input when the user inputs a telephone number or performs key input for designating the destination as an input mode of the device. In step ST14, the conversion table server 100 determines the command transmission source device and the destination device from the correspondence table between the IP address and the device type stored in the storage unit, and the subsequent step. In ST15, by referring to the conversion table 101 (FIG. 5), the command input in the above-described step ST11 is changed to a command corresponding to the destination model based on the correspondence between the transmission source device and the destination device. Convert to Then, the conversion table server 100 moves to step ST16 and transmits the command converted in step ST15 to the destination address.

  In this way, in the conversion table server 100, by converting the input command into a command that can be recognized by the destination device and has the same meaning (purpose), different types of devices (for example, door phones) 50 and the IP telephone 60) can also exchange commands to perform desired processing. Note that commands that can be recognized and have the same meaning (purpose) are, for example, the purpose of operating an off-hook key for the purpose of calling the other party on the IP telephone 40 and the purpose of calling a person inside the room on the door phone 50. The operation of the call button 51 is associated with the same purpose with respect to the purpose of “calling a partner”. Such association is set in advance in the conversion table server 100, and by updating the conversion table 101 as necessary, it is possible to cope with addition of devices and addition of new functions.

  After converting the command, the conversion table server 100 transmits the converted command to the IP-PBX 80 together with the transmission destination address. The IP-PBX 80 transmits the command to the destination device based on the destination address. The destination device that has received this command can understand the command because the command has been converted by the conversion table 101 of the conversion table server 100, and executes processing according to the command.

  According to the IP telephone system 10 described above, by using the conversion table 101 of the conversion table server 100 to exchange commands between different devices, the command transmission source device and the command transmission destination Even if the types of devices are different, the command transmitted from the transmission source can be converted into a command having the same meaning (purpose) that can be recognized by the transmission destination device. Thus, it is possible to execute the intended processing of the command transmitted from the transmission source in the transmission destination device.

  In the first embodiment described above, the conversion table server 100 having the conversion table 101 has been described as performing command (function) conversion. However, the scope of the present invention is not limited to this. For example, the conversion table 101 and the correspondence table between the IP address and the device type are stored in each device (computer 40, door phone 50, IP telephone 60), and the command is referred to the conversion table 101 and the correspondence table in each device. (Function) may be converted. In this case, in the transmission source device, the determination is made based on the model correspondence table of the transmission destination device, and after the command (function) is converted according to the model, the converted command (the converted function is executed). Command), or when receiving a command from the transmission source at the destination device, determine the model corresponding to the IP address of the transmission source with reference to the correspondence table, and It is possible to apply a configuration in which the command is converted into a command for executing a function that can be executed by the own model based on the correspondence with the received command. In addition, when each device stores the conversion table, when each device starts up (or when connected to the IP network 12), a method of downloading the conversion table 101 from the conversion table server 100, or in each device, the conversion table 101 Can be used.

  In the first embodiment, the case where the present invention is applied in the range of one IP network 12 has been described. However, the scope of the present invention is not limited to this, and other networks (for example, The present invention can also be applied to the case where communication is performed with each device connected to the IP network 13) (when a command is exchanged).

  In the first embodiment described above, when the source model and the destination model are the same model, conversion to the same command (function) is performed in the conversion table. The command (function) is not converted, but if the destination model is the same as the source model, a processing procedure that does not perform the conversion process may be executed.

  In the first embodiment described above, the case where the present invention is applied to the IP network 12 has been described. However, the scope of the present invention is not limited to this, and the present invention is also applicable to a network system using other protocols. Can be applied.

  In the first embodiment described above, the case where the computer 40, the door phone 50, and the IP telephone 60 are used as devices connected to the IP network 12 has been described. However, the scope of the present invention is limited to this. Instead, the present invention can be applied when other various devices such as an authentication device provided in an entrance / exit area are used. In addition, when the call button 51 is pressed on the door phone 50, the function is not limited to making a call to the IP phone, and when a person is photographed by the camera 58 provided on the door phone 50, the predetermined IP phone 60 or the computer 40 is used. The present invention can be applied to various processes such as sending a notification to the user.

  The present invention is not limited to the first embodiment described above, and can be implemented with various modifications.

(Second Embodiment)
In the first embodiment described above, a case has been described in which one process (function, operation) is executed in the transmission destination device for one command transmitted from the transmission source device. However, the present invention is not limited to this, and a plurality of processes (functions and operations) may be executed in the transmission destination device for one command transmitted from the transmission source device. In addition, according to one command transmitted from the transmission source device, processing is performed in a plurality of transmission destination devices in order, so that a plurality of commands (functions and operations) are associated with one command. You may make it perform.

  That is, in conversion table server 100 of IP telephone system 10 according to the present embodiment, in addition to conversion table 101 shown in FIG. 5, conversion table 201 shown in FIG. 7 is stored in the storage unit. In this conversion table 201, in each device connected to the IP network 12, one sequence is assigned in advance depending on the relationship between the transmission source device and the command generated in the device. For example, in response to the pressing operation of the call button 51 on the door phone 50, a command representing “a processing instruction when the door phone call button is pressed” is transmitted from the door phone 50 to the IP network 12. Then, the conversion table server 100 receives this command. The IP address of the transmission source is added to this command, and the conversion table server 100 determines the transmission source device by referring to the correspondence table between the IP address and the device. Then, “sequence 1” is executed from the conversion table 201 based on the fact that the transmission source device is the door phone 50 and the generated command is “a processing instruction when the call button of the door phone is pressed”. Judge that it should be.

  FIG. 8 is a flowchart showing a conversion processing procedure in the conversion table server 100. As shown in FIG. 8, the conversion table server 100 waits for input of a command from a device connected to the IP network 12 in step ST21. When a command is input from any of the devices, the conversion table server 100 obtains an affirmative result in step ST22, so that the process proceeds from step ST22 to step ST23, where the transmission source of the input command is the transmission source. Judging from the address (IP address).

  Then, in step ST24, the conversion table server 100 refers to the conversion table 201 (FIG. 7) to select a sequence corresponding to the correspondence between the transmission source device and the content of the command, and in subsequent step ST25, The sequence is executed.

  In this way, the conversion table server 100 executes the sequence assigned in advance to the correspondence relationship according to the correspondence relationship between the content of the command and the type of the device that is the source of the command. With regard to devices connected to the network 12, it is possible to perform a cooperative operation by converting commands even between devices of different types.

  As an example of the sequence selected and executed in step ST24 of FIG. 8, FIG. 9 shows that the transmission source is the door phone 50, and the command transmitted from the transmission source is “processing when the door phone call button is pressed. It is a flowchart which shows the sequence 1 selected when it is an instruction | indication. As shown in FIG. 9, in step ST31, conversion table server 100 first sets variable N = 1, and then moves to step ST32 to determine the Nth IP telephone as a transmission destination. In this case, the conversion table server 100 stores the connection order of the plurality of IP telephones 60 connected to the IP network 12 in the storage unit corresponding to the sequence 1, and executes the sequence 1. If the stored IP phone 60 is N = 1, the first IP phone 60 is selected as the destination, and if N = 2, the second IP phone 60 is selected. In the following, the PI telephone 60 corresponding to N = 3, N = 4,... Is selected as a command transmission destination.

  Therefore, in the conversion table server 100, when the Nth IP telephone set 60 is selected and determined as the command transmission destination in step ST32, the process proceeds to step ST33, and the command is converted according to the transmission destination (IP telephone set 60). In this case, the conversion table server 100 stores the conversion table 101 described above with reference to FIG. 5 in the storage unit in advance, and transmits the transmission source (door phone 50), command (processing instruction when the call button is pressed), transmission Based on the correspondence relationship of the destination (IP telephone 60), a command representing a processing command when the call button is pressed is converted into a command (see FIG. 5) representing a processing command for operating the off-hook key. Thereby, the command transmitted from the door phone 50 in response to the pressing operation of the call button 51 of the door phone 50 is converted into a processing command in response to the pressing operation of the off-hook key in the IP telephone 60.

  In step ST34, the conversion table server 100 transmits the command converted in step ST33 described above to the transmission destination (IP telephone 60). In step ST35, the conversion table server 100 determines whether or not the sequence 1 has ended. to decide. Here, when the call button 51 of the door phone 50 is pressed, the notification to all the IP telephones 60 set in advance as the other party's IP telephones 60 for notifying the fact is not completed. 1 has not ended, and the conversion table server 100 moves from step ST35 to step ST36, updates N by the calculation of N = N + 1, and then returns to the above-described step ST32 to update the new information. The converted command is transmitted to the IP telephone 60 corresponding to N.

  When the transmission of commands to all the IP telephones 60 set in advance is completed, the conversion table server 100 obtains a positive result in step ST35, thereby ending the processing procedure according to the sequence 1.

  Thus, in the conversion table server 100, the sequence corresponding to the type of the transmission source device and the command generated in the device is executed, so that the door phone 50 and the IP telephone are executed by executing the processing set as a sequence in advance. The process based on the command corresponding to the operation by the user is also executed between the different models of 60. In this embodiment, as a sequence, a process of a plurality of steps (for example, sequentially transmitting commands to a plurality of transmission destinations) is executed therein (processing step). Thereby, for example, for one operation performed by the user on the door phone 50, processing for a plurality of other devices is executed, and the user is absent in one IP telephone 60. In addition, by sequentially sending commands to the other IP telephones 60, a response to one of the IP telephones 60 will eventually be avoided and a response to the user who operates the door phone 50 will not be made. be able to. Incidentally, when there is a response in any of the IP telephones 60, the fact is notified to the conversion table server 100, whereby the conversion table server 100 stops the subsequent sequence processing. To do.

  According to the IP telephone system 10 described above, by using the conversion table 201 of the conversion table server 100 to exchange commands between different devices, the command transmission source device and the command transmission destination Even if the types of devices are different, the command transmitted from the transmission source can be converted into a command having the same meaning (purpose) that can be recognized by the transmission destination device. Furthermore, by performing conversion from a command to a sequence that executes a plurality of processes for one command, a more flexible process using a plurality of types of devices connected to the IP network 12 is performed. Can be executed. Thus, it is possible to cause a plurality of devices to execute a process intended by a command transmitted from the transmission source.

  In the second embodiment described above, a case is described in which the conversion table server 100 executes a plurality of processes such as sequentially transmitting converted commands to a plurality of devices (a plurality of IP telephones 60). However, the scope of the present invention is not limited to this. For example, in the conversion table server 100, a plurality of IP telephones 60 from the second to the Nth are sent together with a command to the first IP telephone 60. Commands converted according to the specified information and these models (in this case, all commands are the same because they are all the same model, but if there are different models, different commands converted to match that model) Are collectively transmitted to the first IP telephone 60 and sequentially received from the first IP telephone 60 to the next model (IP telephone, etc.). It may be going to pass.

  Further, in the above-described second embodiment, a case has been described in which another device is operated in response to an operation when the call button 51 of the door phone 50 is pressed. However, the scope of the present invention is not limited to this. However, other various processes can be applied. For example, when an IP telephone 60 is used to simultaneously start a video conference with a plurality of other computers 40, first, the IP telephone 60 is used to simultaneously perform a calling process on the other computers 40. . In this calling process, communication is sequentially transmitted to the other computers 40 by communicating with the other computers 40 via the IP network 12. In this case, since the transmission source device (IP telephone 60) and the transmission destination device (computer 40) are different devices, the conversion table 101 (FIG. 5) of the conversion table server 100 is used. Conversion is performed.

  In response to the call command, the other computer 40 that has received the call command starts up the imaging operation of the camera 48 to photograph a person who operates the computer 40 with the camera 48 and analyzes the captured image. At this time, if a person is reflected in the photographed image, this means that the person participating in the video conference (the user of the computer 40) is present. A reply is sent to the IP telephone 60 that is the source of the command. The source IP telephone 60 establishes a session with the partner computer 40 by this reply. In the IP telephone 60 of the transmission source, the computer 40 in which the participant is present is executed by executing the process related to the calling command on the computers 40 of all the subjects who are scheduled to participate in the video conference. A video conference can be started by establishing a session only with the. As described above, the IP phone 60 that is the transmission source of the general call performs transmission to a plurality of computers 40 and uses the camera 48 in each computer 40 only by performing a key operation for performing a conference once. The session can be established by determining the presence or absence of each user. Note that a program for executing these processes is stored in advance in each device.

  In the second embodiment described above, the conversion table server 100 having the conversion tables 101 and 201 has been described as performing command conversion. However, the scope of the present invention is not limited to this. For example, conversion tables 101 and 201 and a correspondence table between IP addresses and device types are stored in each device (computer 40, door phone 50, IP telephone 60), and the conversion tables 101 and 201 and the correspondence table are referred to in each device. Then, the command may be converted. In this case, in the transmission source device, it is determined by the correspondence table of the model of the transmission destination device, and after the command conversion corresponding to the model is performed, the converted command is transmitted, or in the transmission destination device When a command is received from the sender, the model corresponding to the IP address of the sender is identified with reference to the correspondence table, and the model can be recognized from the correspondence between the sender model and the received command. It is possible to apply a configuration for converting to a simple command. In addition, when each device stores a conversion table, when each device starts up (or when connected to the IP network 12), a method of downloading the conversion tables 101 and 201 from the conversion table server 100, or a conversion in each device A method of always storing the tables 101 and 201 can be used.

  In the second embodiment, the case where the present invention is applied in the range of one IP network 12 has been described. However, the scope of the present invention is not limited to this, and other networks (for example, The present invention can also be applied to the case where communication is performed with each device connected to the IP network 13) (when a command is exchanged).

  In the second embodiment described above, when the transmission source model and the transmission destination model are the same model, conversion to the same command is performed in the conversion table. Although conversion is not performed, if the transmission destination model is the same as the transmission source model, a processing procedure that does not perform the conversion process may be executed.

  In the second embodiment, the case where the present invention is applied to the IP network 12 has been described. However, the scope of the present invention is not limited to this, and the present invention can be applied to a network system using another protocol. Can be applied.

  In the second embodiment, the case where the computer 40, the door phone 50, and the IP telephone 60 are used as devices connected to the network 12 has been described. However, the scope of the present invention is not limited to this. For example, the present invention can be applied when other various devices such as an authentication device provided in the entrance / exit area are used. In addition, when the call button 51 is pressed on the door phone 50, the function is not limited to making a call to the IP phone, and when a person is photographed by the camera 58 provided on the door phone 50, the predetermined IP phone 60 or the computer 40 is used. The present invention can be applied to various processes such as sending a notification to the user.

  The present invention is not limited to the second embodiment described above, and can be implemented with various modifications. As long as it does not deviate from the scope of the present invention, it is possible to appropriately change and implement the processing unit and the processing procedure. Other modifications can be made without departing from the scope of the present invention.
