  Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing an IP telephone system according to an embodiment.
As shown in FIG. 1, the IP telephone system includes a plurality of IP telephone apparatuses 100 to 300. IP telephone apparatuses 100 to 300 are set so as to be able to make a call between IP telephone apparatuses via an IP network.

  A call method between IP telephone devices may be any method, a call may be set directly, a session may be set using SIP, or another method may be used. In addition, a system capable of making a group call is preferable. In the following description, description of call setting and voice communication is omitted.

IP telephone devices 100 to 300 have telephone means for making an IP phone call, reproduction means for reproducing stored contents, transmission means for sending the contents to the telephone counterpart, and contents sent from the telephone counterpart And storing means for causing the reproducing means to reproduce the transmitted content. For example, content, which is an image, music, a web page, or the like obtained from the web server 400, is played back by a display unit or a speaker of each IP telephone apparatus, and the file format and output format are not limited.
The IP telephone devices 100 to 300 use the above-mentioned means to reproduce the content received and stored from the Web server 400 during a telephone call via the IP network and to play the content with the IP telephone device of the other party. Send the content, or accept and store the content from the other party and play the content. In this way, the reproduction of content is synchronized with the telephone partner. That is, when synchronizing the playback of content between IP telephone devices, the content acquired from the server by a specific IP telephone device is sent directly to the IP telephone device of the telephone destination along with the playback, and becomes the receiver side The IP telephone device plays it immediately.

  As for the reproduction of the content that requires the user's operation, the content may be sent to the other party's IP telephone device during the call together with the reproduction operation, or the other party's IP telephone device during the call without waiting for the reproduction instruction. It may be sent and notified as operation instruction information that a reproduction instruction has been received.

  Web server 400 is a general server and provides content to the IP telephone apparatus. Examples of the content to be provided include a web page, a moving image file, and a music file. The Web server 400 may be an internal server or an external server (Internet server), and may be in any location.

  The exchange 500 relays calls between extension lines and outside lines. The exchange 500 manages IP addresses of individual IP telephone devices and peripheral devices and responds to inquiries as necessary, and provides various functions such as group calls, transfer calls, and answering machine services.

  In the above IP telephone system, content to be reproduced on the IP telephone is shared and reproduced by a plurality of units. The operation will be described below.

  FIG. 2 is a sequence diagram for explaining the operation of the IP telephone system. As shown in FIG. 2, a call is made between IP telephone apparatuses 100 and 200. At that time, the content acquired by the IP telephone apparatus 100 from the Web server 400 is shared between the IP telephone apparatus 100 and the IP telephone apparatus 200 and reproduced.

  IP telephone apparatus 100 sets up a call with IP telephone apparatus 200 via the IP network (step S1). For example, a session may be established between devices using the SIP method. Further, each IP telephone device may exchange necessary information such as an IP address with the exchange 500, SIP server, or the like as necessary.

  Next, the IP telephone apparatus 100 and the IP telephone apparatus 200 exchange the event notification for setting to share and reproduce the content during a call, and perform synchronization setting (step S2). This processing may be started, for example, by the user operating the content synchronization setting previously assigned to the function button from one IP telephone apparatus, or may be performed simultaneously with the call setting. . In addition, an acoustic identification unit may be provided to identify a predetermined DTMF signal sequence input and the transmission side reception side may perform the setting process. By this negotiation processing, it is identified that the mutual IP telephone devices perform content exchange and synchronization.

  Next, the IP telephone device 100 acquires the content to be reproduced from the Web server 400 and stores and holds it (step S3). This process may be performed using a Get command or the like for a Web page, and may be performed using a general command.

  Next, IP telephone apparatus 100 reproduces the acquired content and sends the content to IP telephone apparatus 200 that is the other party (step S4).

  Next, IP telephone apparatus 200 reproduces the sent content (step S5). At this time, it is desirable to send a response to the content being sent to IP telephone apparatus 100.

  Further, at this time, IP telephone apparatus 100 and IP telephone apparatus 200 may perform processing for improving the synchronization with respect to the reproduction of content. In order to improve the synchronization, the reproduction start timing in IP telephone apparatus 100 and IP telephone apparatus 200 is adjusted.

  The adjustment of the reproduction start timing is performed by adjusting the reproduction start timing of the content on the IP telephone device 100 by transmitting the content to the partner IP telephone device 200 and starting reception, completion of reception, intermediate specific points from start to completion, etc. The adjustment processing may be performed at the timing when any or a plurality of responses shown are received. The waiting time may be adjusted in accordance with the content type, transfer amount, communication speed, and the like. In other words, the transmission side IP telephone apparatus receives a signal that can measure the reproduction start timing on the reception side as a response, measures the reproduction start based on the signal, and achieves synchronization. In this way, it is possible to reproduce the transmission content as desired by adjusting the time difference between the reproduction start timing of the other party IP telephone apparatus and the reproduction start timing of the transmission side IP telephone apparatus.

  Further, the IP telephone device 100 on the content sending side generates operation instruction information so that the operation related to the content received from the user is expressed in the same manner as the operation, and transmits it to the IP telephone device 200 during the call. Alternatively, it may be transmitted.

  Similarly, when the content-side IP telephone device 100 receives an operation related to the content and appropriately communicates with the server, the other side also performs the same operation as that operation, that is, the operation is performed. In order to be reflected, content transmission and operation instruction information may be transmitted to the IP telephone device 200 during a call.

  Further, the IP telephone apparatus 100 accepts the operation instruction information generated by the IP telephone apparatus 200 so that the IP telephone apparatus 200 which is the other party of the call can operate the content reproduced on the transmitting side IP telephone apparatus 100. May be.

  By performing such processing, information can be updated in real time in the same manner, for example, when referring to Web content including a script or on the screen of the IP telephone device of the other party. As a result, for example, it is possible to follow a change in a Web page that is changed by a user's operation on an IP telephone device employing a touch panel.

  Further, the content transmission side IP telephone apparatus 100 notifies the information about the performance, resolution, software version, etc. of the own apparatus as environment information related to reproduction together with the content, and the content reception side IP telephone apparatus is based on the information. The content received by the user 200 may be adjusted and reproduced. By providing this processing, the content can be reproduced more like the counterpart device. That is, reproducibility can be improved.

  By repeating the processes in steps S3 to S5, the content reproduction is synchronized with the telephone partner. That is, the screen, sound, and the like based on the content data acquired from the server by the IP telephone device can be satisfactorily shared among the IP telephone devices on the phone. Similarly, content playback can be shared and synchronized in a group call.

According to this method, many beneficial effects can be obtained.
For example, it is possible to reduce the load on the server from which the content is acquired. For example, it becomes more prominent in a server that cannot process a relatively large number of requests, such as an HDD server on a LAN provided in a local IP telephone system. In addition, the content obtained from the server as the acquisition source can be surely the same.
For this reason, for example, even if there is something that is not clear on the display screen or usage method, the inquired side can recognize the content of the inquiry while confirming the content along with the telephone inquiry. In addition, the explanation side can select and provide the content. In this example, it is possible to shorten the time for explanation and improve accuracy.

Next, embodiments will be described using examples.
In this embodiment, a description will be given using the configuration of two IP telephone devices connected to a local area LAN and a Web server. Further, Web pages are individually displayed as contents in synchronism with the calling party between the IP telephone devices.

FIG. 3 is a functional block diagram showing a configuration example of the IP telephone apparatus.
The IP telephone apparatus includes a control unit that has a handset, a display screen, a numeric keypad, a speaker, various control buttons, and the like, and manages the overall operation, and a ROM and a RAM as storage units. A touch panel is used for the display screen. Further, as shown in FIG. 3, the IP telephone apparatus includes a telephone function unit 110 as telephone means for making an IP telephone call by controlling the entire apparatus and detecting an input from a numeric keypad, and a browser 120 as reproduction means for reproducing contents. The storage unit is provided with a content temporary storage unit 130 that holds and manages content acquired from a server or a call partner. In addition, a Post request transmission unit 140 is provided as a transmission unit for sending content to be played back to the other party, and a Post request processing unit 150 is provided as a unit for reproducing the content sent from the other party.

  The telephone function unit 110 comprehensively manages the telephone function of the IP telephone apparatus. It is also responsible for linking the various parts related to content sharing.

  The browser 120 transmits a Web page data acquisition request to the Web server by a user operation and receives a response from the Web server. The response includes Web page data, and a screen is formed using the data and displayed on the display unit.

  The content temporary storage unit 130 may be realized by a sharing function of the storage unit or a server function. The content temporary storage unit 130 temporarily stores the content acquired from the Web server or the partner device, and synchronizes the display in cooperation with the Post request transmission unit 140 and the Post request processing unit 150.

  In response to the request from the temporary content storage unit 130, the Post request transmission unit 140 transmits a Post request to the other party's IP telephone device (Post request processing unit 150).

  In the other party IP telephone device, along with the response to the received Post request, the actual data (Web page data) included in the Post request is acquired and stored in the content temporary storage unit 130, and the screen is displayed using the browser 120. .

  Next, the operation in the above-described configuration of the processing operations in steps S3 to S5 shown in the flowchart of FIG. 2 will be described in detail.

  The telephone function units 110 of the IP telephone apparatus negotiate to perform call setting and content synchronization processing in response to an input to the caller's numeric keypad, an input to a function button, an input to a touch panel, and the like. Complete.

  The browser 120 of the IP telephone device transmits a required request to the Web server in order to perform a screen transition to be displayed based on a change with time or a user operation. In response to this request, the Web server that has received the request returns content (Web page data) corresponding to the request (step S3 in FIG. 2).

  The browser 120 that has received the response causes the temporary content storage unit 130 to store the content and displays the received Web page in order to temporarily store the received content. At the same time, the Post request transmission unit 140 places the received Web page data in the POST request and transmits it to the IP telephone device of the other party (step S4). It should be noted that it may be configured such that processing other than the browser performs processing for storing in the content temporary storage unit 130. Moreover, you may utilize the cache data of a web page.

  The receiving side IP telephone apparatus acquires the Web page data included in the received POST request. Thereafter, the Web page data stored in the content temporary storage unit 130 is displayed on the screen by the browser 120 (step S5).

  By performing the processing operation in this manner, the Web page received by the IP telephone device is transmitted to the IP telephone device that is on the telephone, so that the same display screen can be displayed in real time between the IP telephone devices.

Next, an embodiment will be described using another example.
In the present embodiment, description will be made using the configuration of the two IP telephone apparatuses 100 and 200 connected to the private LAN shown in FIG. 1, the IP telephone apparatus 300 and the Web server 400 connected to the Internet. In addition, the display screen is synchronized while a three-party call is made between the three IP telephone apparatuses as a Web page as content.

  FIG. 4 is a functional block diagram showing a configuration example of the IP telephone apparatus. In addition to the configuration of the IP telephone apparatus shown in FIG. 3, a timing adjusting unit 160, an operation notifying unit 170, and a communication partner location determining unit 180 are added. Other configurations work in the same way as in the previous embodiment.

  The timing adjustment unit 160 adjusts the timing of presenting content on the content transmission side and reception side to the user. This adjustment is such that the reception of the content and the completion of reception from the IP telephone device that is the content receiving side, respectively, so that all of the receiving IP telephone devices that are in a call can play back simultaneously while maintaining a predetermined delay time. Is used to exchange signals so that the transmission side IP telephone apparatus can measure the reproduction start timing on the reception side. The timing adjustment unit 160 waits for playback on the browser until a response is received.

  The operation notifying unit 170 notifies the operation performed on the content transmitting IP telephone apparatus to the receiving IP telephone apparatus as operation instruction information. In addition, the IP telephone device on the receiving side performs an operation on the content being reproduced based on the received operation instruction information. The operation instruction information may include a content acquisition request. At this time, content that is newly required in accordance with the operation may be newly exchanged between the POST request transmission unit 140 and the POST request reception unit 150, or may be directly acquired from the Web server depending on the type of content. You may do it.

  The communication partner location determination unit 180 identifies the location of the partner IP telephone apparatus during a call, and if the content is within a predetermined communication environment (for example, within a LAN, a dedicated line, or a wired environment), the content directly If it is out of the environment, the content is acquired by the other party IP telephone terminal by notifying the URI. Further, both of these processes may be identified for each content to be reproduced simultaneously. In this way, for example, in the IP telephone apparatus on the receiving side, files that are reproduced in the same manner on any IP telephone apparatus, such as individual image files, one video file, and music file, can be obtained from the Internet. On the other hand, it is possible to directly send a file that is likely to change for each device, such as a style sheet, and a method can be selected that causes the side to acquire content according to the characteristics of the file. In addition, the operator of the IP telephone apparatus on the receiving side may be able to switch or select during the call which system or the combination of the contents is to be acquired. This selection may be notified to the IP telephone apparatus on the transmission side by putting it on a general command or method. If it is possible to switch during a call, the synchronization and reproducibility can be improved according to the user's intention.

  Next, the operation in the above-described configuration of the processing operations in steps S3 to S5 shown in the flowchart of FIG. 2 will be described in detail with reference to FIG.

  The telephone function units 110 of the three IP telephone apparatuses complete the negotiation regarding call setting and content synchronization processing. At this time, the connection form and performance of each IP telephone apparatus may be confirmed.

  The browser 120 of the IP telephone apparatus 100 that is the caller sends a required request to the Web server in order to change the screen to be displayed based on changes over time or user operations. In response to this request, the Web server 400 that has received the request returns content (Web page data) corresponding to the request (step S3).

  The browser 120 of the IP telephone apparatus 100 that has received the response causes the content temporary storage unit 130 to store the content. At this time, the IP telephone apparatus 100 uses the timing adjustment unit 160, the operation notification unit 170, and the communication partner location determination unit 180 to wait for the reproduction of the content, and for each partner as illustrated in FIG. Depending on the type of received content and the position of the other party, it is determined whether the individual content data is sent by the POST command or the URI is notified and is acquired on the other device side, and the content sent by the POST request based on the determination result , Operation instruction information, environment information related to reproduction by the own apparatus, and the like are appropriately included and sent to the receiving side (step S4). At this time, the file acquisition processing method can be changed between the IP telephone apparatus 300 connected to the Internet and the IP telephone apparatus 200 connected to the LAN. In addition, data that may change for each device such as a display style is directly sent after file conversion as necessary, thereby eliminating display differences for each device and improving reproducibility.

  The IP telephone devices 200 and 300 on the receiving side perform a response in response to the sent POST request and operate based on the sent information to reproduce the content (step S5).

  The IP telephone apparatus 100 that has transmitted the POST request waits for the responses to the transmitted POST request to be complete, and starts reproducing the content (step S4).

  Thereafter, when the user performs an operation on the content or the like, the same display screen can be displayed in real time among the three IP telephone devices by sequentially repeating the above processing operation. It should be noted that the telephone function unit may be provided with means for appropriately transferring the subject (operating right) to operate the content with a function button, a predetermined DTMF signal string, or the like so that another person or all of the users can operate the synchronized content. Good.

  As described above, according to the present IP telephone system, the same screen as the browser displayed on the specific IP telephone apparatus can be displayed on all the IP telephone apparatuses that are making a call, and in addition to the screen transition. It is automatically synchronized and can be displayed on another IP telephone apparatus in the same manner as the original display.

  In this way, it is possible to confirm with the user's own IP telephone apparatus what screen the call partner is viewing including the screen transition. Therefore, for example, when answering a question in the case of a hospitality business such as a hotel, it is possible to serve customers while looking at the same screen as the customer, reducing the occurrence of misalignment and misunderstanding, and giving appropriate instructions And can give advice.

  In the above description, the IP telephone apparatus has been described. However, the present invention can also be applied to an IP telephone terminal using a personal computer. That is, the same effect can be obtained even when an IP telephone application capable of displaying content is used instead of the IP telephone apparatus. In this case, the content temporary storage unit 130, the POST request transmission unit 140, the POST request processing unit 150, and the like may be constructed on a personal computer that operates the IP phone application and operate as an IP phone terminal. This form using a personal computer is suitable for a use form for explaining to a customer such as a call center.

  Alternatively, XML data may be converted into HTML data and sent from an IP telephone terminal apparatus (IP telephone terminal and IP telephone apparatus using a personal computer) on the content transmission side.

  If the form by the personal computer is described in another expression, an information processing apparatus (IP telephone terminal apparatus) that operates as an IP telephone terminal is based on an IP telephone application developed in a RAM, a temporary content storage unit, a POST request transmission unit The control unit may be operated as a POST request processing unit, a timing adjustment unit, an operation notification unit, and a communication partner location determination unit, and an IP telephone function may be realized in cooperation with a browser or an existing configuration.

  The program may be recorded on a storage medium and distributed. The program recorded on the recording medium is read into a memory via a wired, wireless, or recording medium itself, and operates a control unit or the like. Examples of the recording medium include an optical disk, a magnetic disk, a semiconductor memory device, and a hard disk.

  The IP network may use any form, and may be wired, wireless, or a network in which they are mixed.

  As described above, the IP telephone apparatus to which the present invention is applied can synchronize the content to be reproduced with the other party on a plurality of units.

  In addition, it is possible to improve the synchronization speed when content is synchronized in the IP telephone system, improve reproducibility, and reduce addition to the server and communication environment.

  That is, according to the present invention, it is possible to provide an IP telephone system, an IP telephone apparatus, and a content synchronization method that can share and reproduce content reproduced by an excellent IP telephone with a plurality of devices.
