## Title
Communication system

## Abstract

The present invention provides an easy-handling and highly-convenient communication system having sufficient adaptability even when a user does not want to transmit a live picture. In a user database for a service provider system, the user establishes beforehand information on designating image data to be transmitted to a communicated party according to each communication condition such as time, the communicated party or the like, and registers the image data to be used in an image database. When connections are established between a plurality of users via an access provider system, a server apparatus receives the live pictures from each user, determines data to be transmitted to each user by referring to the user database, reads out contents of the image database as required, and transmits to each user selectively the live picture or the read-out image data.

## Background
This application is a continuation of Ser. No. 09/817,599, filed Mar. 26, 2001 now U.S. Pat. No. 6,600,508.


BACKGROUND OF THE INVENTION
1. Technical Field of the Invention
The present invention relates to a highly convenient communication method in a communication network capable of transmitting arbitrary data including a motion picture, a communication service apparatus providing such communication, a communication terminal device for performing such communication and a communication system as such.
2. Description of the Related Art
With the progress of communication technology and various data processing technologies including coding technology or the like, a portable terminal device has been developed, which is capable of processing a great amount of data such as a motion picture. It may be considered that such communication terminal device as capable of processing a real-time motion picture (hereinafter called “live picture”, in some cases) will practically come into wide use when a shortly scheduled broadband communication network begins to be utilized. Additionally, as one of the devices which widely prevail among such communication terminal devices, there is considered the communication terminal device in the form of a videophone which is so far being put to practical use in various systems, namely, a portable communication terminal device capable of mutually transmitting live pictures.
However, as has been the case with the hitherto videophone, against such the communication terminal device, an attention has up to now been paid only to transmitting a live image, in other words, it has been positioned, in most cases, as a dedicated device for transmitting live image. For instance, Japanese Unexamined Patent Application Publication No. 2000-172611 discloses a technology that displays the image of WWW browser in a separate window within the videophone monitor, while calling with the videophones among multipoint. It also discloses the technology regarding the videophone system which includes a videophone device, a multipoint connecting device for controlling a videophone conference connected multipoint and a browser-coupled switching means which notifies as data the other videophone device via the above multipoint connecting device of the files as data which the videophone device downloads from a WWW server. However, this notifying data is notified to all the other connected videophones with the same content, and it is not such that data is notified after selected individually and separately.
As a consequence, a function as a communication means has not been sufficient and effective communication has not been performed. More specifically, there has been problems that adaptability when a user does not want to transmit, for instance, the live picture is insufficient, in addition to difficulty to use.
Moreover, data processing capability that permits real-time transmission of the moving image has not been utilized except for transmission of the live image. Therefore, there has been a demand to provide such a high value-added communication terminal device that more effectively utilizes such data processing capability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1 to FIG. 7 and FIGS. 8A to 8C, an embodiment of the present invention is described below. This embodiment refers to a communication system in the form of a videophone by which callers may transmit real-time moving images to each other. Particularly, the present invention is described by illustrating a communication system referred to as a party line, capable of communicating simultaneously among many callers.
First, there is described a configuration of the communication system by referring to FIGS. 1 to 6.
FIG. 1 is a view showing a fundamental configuration of the communication system 11.
As illustrated, the communication system 11 comprises, as its fundamental configuration, a plurality of user terminal devices 100, an access provider system 200, and a service provider system 300.
The user terminal device 100 is a communication terminal device with functions of voice communication, image displaying, capturing a picture of a user and the like, so that users may communicate with each other by way of voice and image.
The user terminal device 100 is described in detail with reference to FIGS. 2 and 3.
The user terminal device 100 comprises a camera 103, an image coding unit 104, an image decoding unit 106, a display 108, a microphone 110, a voice coding unit 112, a voice decoding unit 114, a speaker 116, a key input unit 118, a memory 120, a communication I/F (Interface) 122 and a CPU (Central Processing Unit) 124.
The camera 103 is a compact CCD (Charge-Coupled Device) camera provided at the position from where the user may photograph the portion of his face when the user applies the user terminal device 100 under normal condition. When the user terminal device 100 is used, the camera 103 captures the user, and outputs an acquired image signal to the image coding unit 104.
The image coding unit 104 encodes the picture signal inputted from the camera 103 by the predetermined mode, and outputs to the communication I/F 122.
The image decoding unit 106 decodes each of the encoded image data of each called party which is received and inputted at the communication I/F 122, and applies to the display 108 after converting to a signal which is displayable on the display 108.
The display 108 displays the image data of each called party to be inputted from the image decoding unit 106. For instance, when the user is simultaneously calling three individuals including himself, three frames 109-1 to 109-3 adapting to each caller are displayed on the display 108 as shown, for example in FIG. 3, and real-time moving images of each caller (hereafter called a “live pictures” in some cases) or specific image data or information or the like designated by each caller are displayed.
Additionally, the display 108, though not shown, also displays,. according to control of CPU 124, information on using conditions or operation of the user terminal device 100.
The microphone 110 captures exterior voice including utterance of the user on calling, generates a voice signal and outputs to the voice coding unit 112.
The voice coding unit 112 encodes the voice signal inputted from the microphone 110 by the predetermined mode and outputs to the communication I/F 122.
The voice decoding unit 114 decodes encoded voice data received and inputted at the communication I/F 122, converts to a signal capable of outputting from the speaker 116, and applies to the speaker 116.
The speaker 116 outputs in sound voice a voice signal inputted from the voice decoding unit 114.
The key input unit 118 is an operating unit where the user dials a party to be called, sets various functions of the user terminal device, sets and requests various services for the service provider system 300. The setting for the service provider system 300 is that of designating image data or the like displayed on the terminal device of the called party.
The memory 120 stores various data of not only a processing program for controlling the whole user terminal device conducted by the CPU 124 and data for setting function and operation of the user terminal device 100, but also intermediate data in process at the CPU 124, data transmitted among each component unit and intermediate data in process at each component unit.
As data particularly related to the present invention, information about a called party, communication conditions or specific image data to be displayed by operation on a display 108 of the user terminal device 100 which is being used by a called party, and also a specific image data to be displayed on the display 108 by instructions from a called party whom the user terminal device 100 is related to and has the possibility to communicate with, are stored in the memory 120.
The communication I/F 122 performs modulation, demodulation and protocol control, and actually communicates with an outside device. A voice data inputted to the microphone 110 and encoded by the voice coding unit 112, and an image data captured by the camera 103 and encoded by the image coding unit 104 are transmitted from the communication I/F 122 to the service provider system 300 via the access provider system 200. In addition, data transmitted from the service provider system 300 via the access provider system 200 is received by the communication I/F 122 and outputted to the image decoding unit 106, the voice decoding unit 114 or the CPU 124 or the like.
The CPU 124 operates according to a program stored in the memory 120 and controls each unit of the user terminal device 100 so that the user terminal device 100 may perform desired operation. Accordingly, it may be understood that the memory 120 is comprised of a read only memory (ROM) which stores this program and a random access memory (RAM) which stores and reads out the image data or the like.
In such configured user terminal device 100, the communication I/F 122 begins to communicate with the outside device according to control of the CPU 124 by operation, for example, of the key input unit 118 by the user.
When a channel is secured, a voice uttered by the user is captured by the microphone 110 and converted to a digital coding signal at the voice coding unit 112, and a picture of the user is captured by the camera 103 and converted to a digital coding signal at the image coding unit 104. Each of them is transmitted from the communication I/F 122. A voice signal of a communicated party received at the communication I/F 122 is decoded at the voice decoding unit 114 and outputted from the speaker 116, and a picture signal of a communicated party received at the communication I/F 122 is decoded at the image decoding unit 106 and displayed on the display 108.
With this procedure, a call in the form of Videophone with an arbitrary called party is available. Additionally, by utilizing a service provided by the service provider system 300 described later, a simultaneous communication with three or more users is available.
In making such basic calls, based on operation of the key input unit 118 of the user or by a service provided by the below-described service provider system 300, various forms of calls related to the present invention are available, which will be described bellow in detail.
The access provider system 200, according to requests from each a nodal device, effects a line connection between arbitrary nodes on a communication network provided by the access provider system 200 including the user terminal device 100 and the service provider system 300, whereby communication between each device may be available.
As a processing related to this embodiment, an arbitrary user terminal device 100 requests the service provider 300 for a primary connection, so that the access provider system 200 effects a line connection between this user terminal device 100 and the service provider system 300 in reply to the above request. In the case where the request of connection by this user terminal device 100 is that of a call to the other user terminal device 100, the access provider system 200, in reply to the request of the service provider system 300, effects a secondary line connection between the access provider system 300 and the user terminal device 100 used by a called party.
Thus, a communicable environment is provided between the user terminal device 100 originating request for connection and the user terminal device 100 of a called party via the service provider system 300.
Incidentally, the access provider system 200 connects each device through various formed channels, but ultimately connects each device through the channels having enough bandwidth capable of transmitting real-time moving images.
The service provider system 300 is a server apparatus providing various communication services to each of a plurality of the user terminal devices 100 via the access provider system 200.
Fundamentally, the service provider system 300 intermediates connections between a plurality of the user terminal devices 100 and provides those of the user terminal devices 100 with a communication service in the form of a videophone including mutual transmission of moving images. In that case, the communication services makes it possible to transmit not only a simply captured real-time picture but also other moving image data, static image data or arbitrary information as replaced data for display, according to the request from the user, specific condition or the like.
Referring to FIG. 1 and FIGS. 4 to 6, there is described such service provider system 300.
FIG. 4 is a block diagram showing a configuration of the service provider system 300.
As shown in FIGS. 1 and 4, the service provider system 300 comprises a server apparatus 310, a user database 320 and an image database 300, and, as shown in FIG. 4, the server apparatus 310 includes a communication I/F 311, a selection unit 313, a database I/F 315 and a control unit 317.
The communication I/F 311 of the server apparatus 310 is connected via the access provider system 200 to the user terminal device 100, and communicates with each of the user terminal device 100 to provide predetermined services.
Normally, the line connection between the user terminal device 100 of a caller originating a request for connection for call, and the user terminal device 100 of a called party to whom connection is requested, is done to the communication I/F 311 via the access provider system 200. The communication I/F 311, when receiving the voice signal and the image signal related to the call from each of these user terminal devices, outputs them to the selection unit 313, and also transmits the voice signal and the image signal related to the call inputted from the selection unit 313 to each of the user terminal devices 100. Also, when a control signal for setting conditions or the like against the service provider system 300 is transmitted from the user terminal device 100, the communication I/F 311 outputs it to the control unit 317.
Irrespective of a call, when the user terminal device 100 is connected to the communication I/F 311 for making the setting of the connecting conditions for receiving services or of the image data to be used, the communication I/F 311 outputs to the control unit 317 a control information or the like received from this user terminal device 100. When the control signal against such the user terminal device 100 is inputted from the control unit 317, the communication I/F 311 transmits this to the user terminal device 100.
The selection unit 313, based on the control by the control unit 317, selects and controls data to be mutually transmitted between each connected two or more user terminal devices 100 connected to the service provider system 300.
From the communication I/F 311 to the selection unit 313, the voice data and the picture data which are transmitted from each of the user terminal devices 100 are inputted for each connection consisting of a plurality of the user terminal devices 100 making mutual calls. Regarding the voice data, the selection unit 313, for the purpose of transmitting to all the connected user terminal devices 100, outputs to the communication I/F 311 the received voice data as transmitting data to each of the pertinent user terminal devices 100.
On the other hand, regarding the picture data, the selection unit 313, through each combination of the user terminal device 100 originating transmission of the picture data and the user terminal device 100 receiving the transmitted picture data, selects by a control of the control unit 317, either the received picture data or the other image data stored in the image database 330, and outputs to the communication I/F 311 for transmitting the selected image data to the user terminal device 100 of the transmitted party.
Though described later, the control unit 317 controls selection of such image data by referring to information on transmitting condition for image data of each user stored in the user database 320. Accordingly, by this processing, it becomes possible to transmit arbitrary static image or moving image to the specific party according to the desire of the user, and it becomes easy to make use of the communication system in the form of videophone of this kind permitting transmission of real-time picture, in comparison with the case of simply transmitting live pictures mutually between each of the user terminal devices 100.
The database I/F 315, based on control from control unit 317, reads out the desired image data from the image database 330 and outputs from the predetermined channel to the selection unit 313. From the database I/F 315 to the selection unit 313, there are a plurality of input-output channels through which the image data can be outputted simultaneously and in parallel, and the database I/F 315 reads out a plurality of the image data in practically simultaneous manner, and outputs to the selection unit 313 via the predetermined channel.
Based on the connecting condition inputted from the communication I/F 311, the control signal directly inputted from the user terminal device 100 via the communication I/F 311 and information on transmitting condition of the image data of each user recorded in the user database 320, the control unit 317 determines the image data to be transmitted to each of the user terminal devices 100 of each established connection, and controls the selection unit 313 so that the determined image data may adequately be transmitted to each of the user terminal device 100. In that case, the control unit 317 controls the database I/F 315 to read out the required image data from the image database 330 and output to the selection unit 313.
When information on transmitting condition of new image data is inputted from the user terminal device 100 via the communication I/F 311, the control unit 317 updates the user database 320 accordingly.
Additionally, when the new image data or data for display are inputted from the user terminal device 100 via the communication I/F 311, the control unit 317 stores them in the image database 330 via the database I/F 315.
The user database 320 is the database which records for each user the data for display to be used against the other user with whom communication is conducted.
Specific examples of the data to be recorded in the user database 320 are shown in FIG. 5.
In the example shown in FIG. 5, when a user A communicates with the a B, the setting is made such that, as the image data to be transmitted to the user B, namely as the image data displaying on the user terminal device 100-B of the user B, the live image is used, namely the data captured at the user terminal device 100-A of the user A at the time of calling and then transmitted.
When the user A calls the a C, the setting is made such that the user A selects a first registered image data registered beforehand in the image database 330 of the service provider system 300, and that when the user A calls users D and E, a second fixed format image data, which has beforehand been prepared by the service provider system 300 and stored therein, is selected.
For the other users who have not made the setting (default), the setting is made such that the user A selects a first fixed format image data which has beforehand been prepared by the service provider 300 and stored therein.
As for the user B, the setting is made such that when he calls the users A and C, the live picture is transmitted from the beginning, and when calling users F, G and H, a second registered image data registered beforehand in the image database 330 is used, and also as the default, a first registered image data registered beforehand in the image database 330 is used.
Further, as for the user C, the setting is made such that the live picture is transmitted to any of the users A, B and E, and, furthermore, the live picture is also transmitted as the default.
The image database 330 is the database recording the image data to be transmitted to each of the user terminal devices 100.
FIG. 6 shows a recording situation of data at the image database 330.
In the image database 330, fixed format image data, image data for controlling and registered image data are recorded in the arrangement, for example, as shown in FIG. 6.
The fixed format image data is the image data which has beforehand been prepared by the service provider system 300 and for which the user substitutes when, for example, the user does not want to transmit the live picture to a called party. In this embodiment, there are registered static image data of cartoon pictures depicting some facial expressions of a normal face, an angry face, a delighted face or the like, or image data of simple landscape.
In addition, data for controlling is the data to be transmitted as a substitute when the desired image data cannot be transmitted due to some influences caused by communication channels, processing capability of the service provider system 300 or the like, and in this embodiment, it refers to the image data of simple pattern with a little amount of data.
Still, registered image data is image data that each user registers to use in place of a live picture, and is an arbitrary image showing, for example, a static image of the user, a simple moving image of specific behavior including laughing, a cartoon picture depicting the user, an image showing the matter which the user has interest, or the like.
In such image database 330, by the database I/F 315, image data designated by the user terminal device 100 whose connection is established is read out at high speed In addition, newly registered image data from the user is recorded as appropriate via the database I/F 315.
Next, referring to FIG. 7 and FIGS. 8A to 8C, there is described an operation of such communication system 11.
FIG. 7 is a schematic view to describe the operation of the communication system 11 and FIGS. 8A to 8C are schematic views showing the situations of the displays 108 of the user terminal devices 100 of each user.
As shown in FIG. 7, description is made by adopting an example of the case where each user calls under such an environment that the three user terminal devices 100-A, 100-B and 100-C related to the three users A, B and C are connected capable of simultaneous calls.
To begin with, the user A operates the key input unit 118 to call the users B and C and, according to this operation, the access provider system 200 establishes a line connection between the user terminal device 100-A of the user A and the service provider system 300.
The request for connection to the users B and C from the user terminal device 100-A is inputted to the control unit 317 via the communication I/F 311 of the service provider system 300. Based on the control by the control unit 317, the service provider system 300 requests the access provider system 200 to establish line connections to each of the user terminal devices 100-B and 100-C of the users B and C.
In addition, in reply to this request, the access provider system 200 calls up each of the user terminal devices 100-B and 100-C, and the users B and C put the respective user terminal devices 100-B and 100-C in communicating condition, whereby line connections between the service provider 300 and each of the user terminal devices 100-B and 100-C are established.
Meanwhile, the control unit 317 of the service provider system 300 conducts a check of each setting of image data to be transmitted among each of the users A, B and C by referring to the user database 320. For instance, when the setting of the user database 320 is as per indicated in FIG. 5, each live image may be transmitted, from the user A to the user B, from the user B to the users A and C and from the user C to the users A and B, but only from the user A to the user C, a first image data which the user A has registered beforehand is arranged to be transmitted instead of the live image.
Accordingly, the control unit 317 instructs the database I/F 315 to read out a first registered image data of the user A from the image database 330, and the database I/F 315, based on the instructions, reads out a first registered image data of the user A from the image database 330 and outputs to the selection unit 313.
In the situation that connection is established between the service provider system 300 and each of the user terminal devices 100-A, 100-B and 100-C as described above, the voice signal and the image signal are transmitted to the selection unit 313 from each of the user terminal devices 100-A, 100-B and 100-C via the communication I/F 311.
With respect to the voice signal, the selection unit 313 selects the inputted signal from each of the user terminal devices 100-A, 100-B and 100-C so as to transmit to all the user terminal devices 100-A, 100-B and 100-C and outputs to the communication I/F 311.
With regard to the image signal, the selection unit 313 conducts the signal selection for the user terminal devices 100-A and 100-B of the users A and B so as to transmit the signals inputted from each of the user terminal devices 100-A, 100-B and 100-C as they are. In addition, for the user terminal device 100-C of the user C, the selection unit 313 transmits the image signals from the user terminal devices 100-B and 100-C of the users B and C as they are, but does not transmit the image signal from the user terminal device 100-A of the user A, and instead, transmits a first registered image data of the user A inputted from the database I/F 315 as the image signal related to the user A.
FIGS. 8A to 8C show images displayed on the displays 108 of each of the user terminal devices 100-A, 100-B and 100-C when each image signal is transmitted as described above.
FIG. 8A is a view showing the display 108-A of the user terminal device 100-A of the user A, FIG. 8B shows the display 108-B of the user terminal device 100-B of the user B and FIG. 8C shows the display 108-C of the user terminal device 100-C of the user C.
As shown in FIGS. 8A to 8C, on the displays 108-A, 108-B of the user terminal devices 100-A, 100-B of the users A and B, three live pictures of each three users are displayed on three frames of 109-1 to 109-3.
However, on the display 108-C of the user terminal device 100-C of the user C, only a static picture is displayed on the frame 109-1 where the live picture of the user A should be displayed, and the live picture of the user A is not displayed.
Still, under such situation, when any of the users wants to change the condition of the image to be transmitted, a predetermined operation from the key input unit 118 of the user terminal device 100 is performed. As a consequence, the control signal based on this operation is inputted to the control unit 317 via the access provider system 200 and the communication I/F 311, and by the control unit 317, the selection unit 313 and the database I/F 315 are controlled, whereby the condition of the image data to be transmitted is changed.
For instance, in such the case where the user A notices that there is no problem in transmitting the live picture to the user C, when the user A performs the predetermined operation in the user terminal device 100-A, the signal based on this operation is inputted to the control unit 317 of the service provider system 300, and the control unit 317 indicates the selection unit 313 to transmit the live picture from the user terminal device 100-A of the user A as it is to also the user terminal device 100-C of the user C. As a consequence, also on the display 108-C of the user terminal device 100-C of the user C, the live picture of the user A is displayed. At this time, the control unit 317 also instructs the database I/F 315 so as to suspend reading out the registered image data of the user A from the user database 330.
Conversely, for any of the users having already transmitted the live picture to the called party, when the situation has occurred that he does not want the live image to be viewed by the called party, by having the pertinent user instructing the terminal device 100 and performing an operation in order to designate an alternative image, the signal based on these instructions is inputted to the control unit 317 of the service provider system 300, and the control unit 317 instructs the selection unit 313 to transmit the designated image in place of the live picture from the pertinent user to each of the connected parties. As a consequence, on the displays 108 of the user terminal devices 100 of all the connected parties, the live pictures of the pertinent user are not displayed, and instead the alternative images are displayed.
In addition, in the situation of continuing calls in such condition, when the image data cannot be transmitted in real-time and adequately due to the state of the lines, for example, of the access provider system 200 becoming inferior, the communication I/F 311 of the service provider system 300 detects this situation and informs the control unit 317 accordingly.
The control unit 317, based on this information, instructs the database I/F 315 to read out the image data for controlling, as well as instructing the selection unit 313 to transmit this image data for controlling, for example, all the user terminal devices 100. As a consequence, though the live pictures cannot be seen, halfway fragmentation of the image or transmission of poor quality image can be prevented. As a matter of course, if the state of the line may be maintained in good condition by transmitting such image data for controlling to only a part of the user terminal devices 100, a function of transmitting the live image to the other user terminal devices 100 may be maintained by performing such operation.
As described above, according to the communication system 11 of this embodiment, simultaneous communications among three or more users can be performed under an environment in the form of videophones capable of mutually transmitting real-time pictures, and communication among a plurality of users can be performed effectively.
At this event, each user can control the image data to be transmitted to each of the called parties. Accordingly, each user can make use of the communication system 11 in such form of videophone, as his live picture is not necessarily transmitted constantly. By this communication system 11, various convenient forms of communication are available.
For instance, when communication is requested by an unknown party, the user may display on the screen of the unknown party an image such as a landscape image to prevent from disclosing his identity, thereby assuring privacy. Furthermore, the user may be able to transmit a static image such as photography or a cartoon registered beforehand to a party who is his acquaintance but not intimate.
Thus, the user may select the image to show to the called party in accordance with the degree of intimacy, thereby allowing a more diversified communication environment.
When communication under high anonymity is conducted, communication may be activated by intentionally transmitting a picture or image that is not a live picture. Still, an expression of feeling may be conducted effectively by properly switching between the registered picture, the live picture or the like for transmission.
Moreover, the present invention is not limited to the embodiment described above, so that various arbitrary changes and variations are possible.
For instance, the service providing system comprising the access provider system 200 and the service provider system 300 is not limited to such the form as presented in the preferred embodiments described herein, but arbitrary forms are accepted.
For instance, the form in which the access provider concurrently provides such service, namely, a service system integrating the access provider system 200 with the service provider system 300 is acceptable.
FIG. 9 shows an example of such form with a simpler system.
A communication system 12 shown in FIG. 9 comprises a plurality of the user terminal devices 100, an access provider system 400 and a user database 320.
The access provider system 400 is a kind of switching system that allows communication by voice and image between arbitrary user terminal devices 100 according to a request from the user terminal devices 100.
The user database 320 is a database in which only a setting of whether the communication is conducted with image or not is done between each user.
In such configured communication system 12, the access provider system 400, according to request of any of the user terminal devices 100, makes a line connection between the user terminal devices 100, whereby communication in the form of Videophone between the pertinent user terminal devices are available.
In addition, at the time of making the line connection, the access provider system 400 makes a check of the user database 320 and determines whether or not transmission and reception of the image between the pertinent user terminal devices 100 are to be conducted, thereby making it possible to communicate only by voice between the user terminal devices 100 having no setting for transmission and reception of image.
In other words, in such communication system 12, the user may arbitrarily set whether transmission and reception of image is conducted or not, and may obtain a similar effect to the communication system 11 of this embodiment.
Accordingly, the present invention can be effected in such form of the communication system 12.
In the embodiment of the present invention described above, a fundamental configuration is shown having the access provider system 200 and the service provider system 300 in a one-to-one correspondence. However, actually, as shown in FIG. 11, there is considered a form having a plurality of both the access provider systems 200 and the service provider systems 300, so it is also possible to adopt such configuration for the present invention.
In such case, the scope of the service target of each system may correspond with each other as shown in the access provider system 200-1, 200-2 and the service provider system 300-1, 300-2, and like the service provider system 300-3, configuration covering a plurality of the access provider system 200-3, 200-4 as the scope of the service target may be accepted. Conversely, like the access provider system 200-4, configuration of covering a plurality of the service provider system 300-3, 3004 as the scope of the service target may also be accepted.
Furthermore, in the configuration in which a plurality of such access provider system and service provider system exist, the connection made via a system other than the access provider system of the original service target, or the connection to the service provider system of the original service target or the like may be conducted in the same manner as the system of the original service target by setting beforehand a predetermined rule for connection.
Such system is also within the scope of the present invention.
The utilization form of the communication system 11, though the above-described forms in any case refer to the communication conducted between a plurality of users, is not limited to such forms, but may be carried out in another arbitrary forms.
For instance, by utilizing that the user may register an image in the image database 330 of the service provider system 300, even a single user can use the system as a system for temporary data storage.
Such system is described by referring to FIG. 10.
As an example, when a user A comes upon some scene when out of home, which he wants to keep to record, user A captures the scene by a portable terminal device 101 and keeps it recorded as the above-described registered image data in the image database 330 of the service provider system 300 via the access provider system 200.
Upon returning home, for example, user A makes access to the service provider system 300 from a terminal device 102 such as a personal computer, which is suitable for processing image data, and may read out the recorded image data in an audio-visual form of the registered image.
Accordingly, a communication system related to the present invention may be utilized in such manner as described above.
The condition that each user sets in the user database 320 of the service provider system is not limited to only the communicated party like this embodiment of the present invention, so an arbitrary condition can be established.
For example, as shown in FIG. 12, the user may make the settings according to the time of communicating. By doing so, there is no fear that a live picture to show during sleeping or just waking-up is transmitted as it is to the communicated party, which makes it all the more easy to utilize such the communication system.
As a matter of course, such settings by time, by the communicated party or by other various conditions may be allowed to exist in conjunction.
Still, in this embodiment, data to be transmitted to the communicated party in place of the live picture, and data for controlling to be used due to limitation of the channel is set to be, in either case, image data. However, the data concerning the present invention are not limited to image data, and text data indicating arbitrary characters may also be accepted. Furthermore, data in the form of adding voice data or some sort of accompanied data to such the visually recognizable data may also be accepted.
There is also no limitation in image data with respect to the contents, the type (static image or moving image, real image, picture, photograph, cartoon, characters or the like), the forms, and the recording forms.
In addition, the data displayed on the terminal device of the communicated party in place of the live picture is, according to this embodiment, to be recorded in the service provider system 300. However, such data may also be recorded in the user terminal device of the user of the transmitting side, or in the user terminal device of the reception side if communication with the same party is made frequently.
According to the present embodiment of this invention, the operation unit of the user terminal device 100 is a key input unit, but an arbitrary inputting means or operating means such as, for example, a touch panel, a jog dial, a pen input, or a voice input is accepted.
Furthermore, an arbitrary method, kind or form may be used with respect to the connecting method for the access provider, the kind of communication network, the form of transmitting data, the form of the user terminal device or the like, and may not be limited to this embodiment of the present invention.
Thus, the present invention may provide a communication method capable of effectively communicating with enhanced capability of expression by making effective use of processing real-time moving image, thus having an increased convenience and ease of use.
Further, the present invention may provide a communication service apparatus which provides a communication service capable of effectively communicating with enhanced capability of expression by making effective use of processing real-time moving image and with increased convenience and ease of use, as well as a communication terminal device making use of such communication service, and a communication system to provide such communication service.
While preferred embodiments of the invention have been described, such description is for illustrative purpose only, and it is to be understood that changes and variations may be made within the spirit and scope of the invention.
