Description

Connection control method of video communication device and its device {PICTUREPHONE SYSTEM}

The present invention relates to a method and apparatus for controlling a communication connection in a video telephone apparatus using, for example, a PSTN as a video communication apparatus. Particularly, communication mode information (type of modem, transmission speed, etc.) corresponding to the ID together with the counterpart ID is provided. In the case of the same ID input, when the same ID is inputted, the process of exchanging modem information with the other party's video telephone is skipped and the communication mode can be set immediately by using the stored information. A connection control method and apparatus therefor.

In general, as the communication technology and image compression and restoration technology are rapidly improved, a video telephone that can transmit and receive not only a user's voice but also an image in a phone using a PSTN has emerged.

Such a video phone implements video communication in such a manner that two systems simultaneously connect a modem so that video communication can be performed together while making a call like a normal phone.

Therefore, when the modem is connected for video communication as described above, the information exchange (ITU-T V.8) process of informing whether the other party device is a general phone or a modem, and if it is a modem, what kind of modem, When the process is completed, the training (international standard; ITU-T V.34) is performed to determine the data transmission speed between both modems.

This training process is performed every time a video communication connection is made.

Fig. 1 is a block diagram showing the configuration of a video telephone, comprising a camera 1 made up of a CCD 1b for converting an image input through a lens 1a into an electric video signal, and a conversion by the camera 1; A video signal inputted to the camera signal processor 2 and a camera signal processor 2 for correcting the converted video signal to an analog signal having a predetermined level and outputting the digital signal to the digital signal processor (DSP) 3 A digital signal processor (3) for processing the video signal of the other party as a digital signal and outputting it to be displayed on the monitor (4), and outputting it in the format of a luminance signal (Y) and a color signal (Cr, Cb) for image compression. An image compression / recovery unit 5 which is responsible for compressing and restoring an image signal, a modem 6 for transmitting and receiving a compressed image and audio signal, and a modem 6 for receiving the image and audio signal. User interface for operating the machine A system control unit (CPU) 8 for controlling each unit for processing, compression, restoration, and transmission of an image signal in response to a key unit 7 and a key input of the user interface unit 7, It consists of a memory 9 in which information such as a telephone number required is stored.

The conventional communication control operation performed in the video telephone constructed as described above is as follows.

First, an image input through the lens 1a of the camera 1 is converted into an electric image signal through the CCD 1b and input to the camera signal processor 2.

The camera signal processing unit 2 controls the driving of the CCD 1b, corrects the input image signal as an analog signal of a predetermined level, and outputs it to the digital signal processing unit 3.

In addition, the digital signal processor 3 displays the input image through the monitor 4 after performing clamp, RGB color control, and brightness control on the input image signal, for image compression for transmission to the outside. The luminance signal Y and the color signals Cr and Cb are converted into a predetermined format and output to the image compression / restoration unit 5.

Then, the image compression / recovery unit 5 compresses the image signal input from the digital signal processing unit 3 so as to be transmitted, and displays the other party image signal input through the modem 6 on the monitor 4. Restore so that you can.

At this time, when the transmitting side makes a call to the other party using the user interface unit 7, the system control unit 8 recognizes this and enables an analog telephone through a handset (not shown) and a communication line.

Subsequently, when the modem 6 is connected to each other for video communication, when the user presses the modem connection button on the user interface 7, the other device attempts to connect with the other party through the communication line with the modem 6. If it is a modem, it will perform the information exchange process (ITU-T V.8) indicating what kind of modem it is.

When the information exchange process between modem devices with the other end is completed, a process (ITU-T V.34) for determining a data transmission rate by training is performed.

When the transmission speed between the video telephones is determined through the above process, the system controller 8 transmits the compressed video and audio data to the other party (receiving side) through the modem 6 and the communication line. By reconstructing the input compressed image data and displaying it on a monitor (LCD, etc.), and reproducing and outputting an audio signal, video communication is possible.

The signal flow as described above is controlled by the system control unit 8.

That is, in order to perform the video communication, the telephone line is connected to the receiver by the sender dial. Then, the modem waits for a modem connection and then transmits voice and data.

By the way, in the related art, the process of exchanging modem information must be preceded every time the video communication is performed. Therefore, the waiting time for the modem connection takes about 15 seconds to 25 seconds. In other words, it takes 1/2 ~ 1/3 of the total connection time for the information exchange which shows what kind of modem, i.e. international standard ITU-T V.8, and the rest is ITU-T V.34 Occupies.

As such, the process of exchanging modem information between the counterpart devices occupies 1/2 to 1/3 of the total connection time depending on the communication line situation, so that the preceding connection time is lengthened until the present communication (video communication start). The user has to wait for such a long time, which makes the connection insecure and time-consuming, as well as the inconvenience of having to pay for the phone (especially international calls) during that time.

According to the present invention, when performing video communication, the ID of the other party and the communication mode information (modem related information) corresponding to the ID are memorized. A video communication system which, when present, establishes a communication mode corresponding to the ID and establishes a video communication connection with the other party, thereby shortening the communication connection time by omitting the exchange of modem information, wherein the other party ID is a caller at the exchange. In case of providing an ID (sender information) or not, each process is adaptively updated to update the database of ID / communication mode information, and one-touch dialing is performed by matching the other party ID with an image representing the other party. Provided are a connection control method and apparatus for a video communication device.

[First Embodiment]

First, Fig. 2 is a diagram showing the procedure of the connection control method of the video telephone of the present invention when the caller information (Caller ID) is not provided.

When the sender dials the other party's telephone number using the user interface unit 7 for video communication, the telephone number inputted is compared with the telephone number stored in the memory 9 to search for a match. do.

If the telephone number entered as a result of the search is stored in the memory 9, the call indication and the call menu value of the modem of the transmitting and receiving side are set as the default value. Set call display and call menu by modem communication.

If the telephone number by the caller's dial is not stored in the memory, call display (process of recognizing whether each other is modem) and call menu (Modulation Mode, Protocol Mode) are set by communication between modems as before.

When the call display and the call menu of the modem are set in the above process, after setting the transmission rate by training, the process proceeds to data communication.

During the data communication, the other party's phone number is manually stored using the user interface unit 7 for the modem related information identified by the modem related information as the call. Will be stored in.

For example, a method of storing the other party's telephone number (ID) in the memory 9 when it is confirmed by a modem of the same model.

Here, the method of storing the other party's telephone number (the other party's ID) is to enter a specific key (*, #) promised in advance and look at the menu displayed on the monitor 4 as shown in FIG. An example of the same type telephone number list inputted in this way is stored in the memory 9 as shown in FIG.

On the other hand, the memory 9 applies a nonvolatile memory which has no information loss even when the power supply is turned off.

As described above, if the caller ID is not provided, the telephone number by the sender dial is recognized to skip the information exchange process between modems having the same model (ITU-T V.8) and immediately perform the training process. Afterwards, the video communication is possible, and the modem connection time of the video communication device can be shortened by checking the modem types of the other devices and storing the other party's telephone number during the video communication.

On the other hand, if there is no caller ID, the sender may store the receiver's ID together with modem information when the call is successful. In addition, a method of storing the information as a sender ID and modem-related information at the receiving end may correspond to the case where there is no counterpart information.

Second Embodiment

Fig. 3 shows a transmission side access control procedure when sender information (Caller ID) is provided, and Fig. 4 shows a reception side access control procedure when sender information is provided.

Referring to Figs. 3 and 4, the video telephone connection control method when the sender information is provided will be described.

First, a caller inputs a phone number by a caller dial, recognizes an input phone number by the system control unit 8, and then stores the input phone number in a memory 9. The phone number stored in the server is compared to search for a match.

In addition, when the caller ID is inputted by the sender dial, the receiver caller receives the caller phone number from the switch in the system controller 8 and recognizes the call. The number is searched for a match.

Here, since the caller information provided to the receiving end by the exchange of the PSTN communication line includes information such as the caller's telephone number, time, and date, the sender's telephone number can be recognized.

And, if the other party's telephone number is stored in the search result memory, the transmitting and receiving system control unit has communication mode setting information (for example, information using a modem of the same model) for the other party. The call display and call menu of the modem is set based on the communication mode setting information.

If the call display and call menu of the modem of the transmitting and receiving side is set as the basic as described above, the transmission rate is determined by the training and data communication is performed between the transmitting and receiving sides at the determined transmission rate.

In addition, when the other party's telephone number is not stored, since there is no call display and call menu information for the other party's modem, the call display and the call menu are set by modem communication between both parties.

At this time, when the process of setting the call display and call menu by the modem communication is completed, the communication mode setting information (for example, whether the same modem) is determined, and the communication mode corresponding to the call number (ID) of the other party is set. After the information is automatically stored, the transmission speed is determined by training and data communication is possible.

If the modem is not of the same model, the transmission speed is determined by training without storing the input recipient telephone number.

Therefore, according to the connection control method of Figs. 3 to 4, the transmission speed is immediately controlled by omitting the process of setting up the call display and call menu for modem connection by storing the phone number of the counterpart using the same type of modem. It is possible to perform the process of determining the, thereby reducing the preliminary connection time for the image main communication.

In the connection control method of Figs. 3 to 4 described above, there may be a case where the other party's video telephone (image communication system) is changed so that the modem related information does not match although the ID remains the same.

In this case, try to connect the ID with the communication mode setting information a predetermined number of times (n times). If the connection fails, the other party's system is regarded as changed and abandon the other party's ID and communication mode setting information. It is always possible to update the latest data by resetting the counterpart's ID and modem-related information in advance of the information exchange process and the training process.

Third Embodiment

7 to 12 show a third embodiment of a connection control method of a video communication apparatus according to the present invention, by using sender information, whether modem information for a telephone number of the other party is stored in a memory, and modem information of the other party. If there is, the sender / receiver side outputs a certain frequency to the other party, and if they check each other's frequency, they know each other's modem types and protocols. If the sender / receiver cannot confirm a certain frequency, it exchanges the modem information and saves the modem information of the other party together with the telephone number so that the modem connection time can be shortened during the next modem communication. It is.

First, Fig. 7 shows the main keyword procedure of the video communication connection control when the sender information (Caller ID) is provided from the exchange.

Search whether the modem information for the other party's phone number is stored in the memory.

If the other party's modem information is stored in the memory as a result of the search, a predetermined predetermined frequency signal is requested to the other party (Caller), and the other party's response (predetermined predetermined predetermined frequency signal) is detected ( Answer to Caller.

In this case, when a predetermined frequency signal is detected according to the other party's response, the communication speed is determined by training, and data communication is performed at the determined communication speed.If the frequency signal according to the other party's response is not detected, the modem information exchange process is performed. The modem information is stored in the memory along with the phone number, and the data rate is determined after the communication speed is determined by training.

The connection control method of the video telephone using the sender information according to the present invention proceeds as described above in more detail with reference to Figs.

First, since the communication line (exchange) provides the caller information (Caller ID) such as the caller's telephone number, date, and time to the receiver, the receiver can recognize the phone number of the sender.

When the caller makes a call to the receiver by dialing, the system controller (CPU) enables an analog call through the handset and the communication line, and retrieves modem information of the other party's telephone number from the memory.

Here, the memory stores the other party's telephone number and modem information, that is, a modulation mode and a protocol mode, and applies a nonvolatile memory that does not lose even when this information is turned off.

As shown in Fig. 8 and Fig. 9, the caller of the transmitter and receiver receives a caller by searching for the other party's (receiver) phone number input by the user using the phone number stored in the memory. It searches for the number and modem information about it.

If there is modem information for the receiver's telephone number in the memory of the caller, the modem is set to match the state of the modem information (Modulation Mode, Protocol Mode). ) Will be set.

The caller recognizes the caller's telephone number from the system controller using the sender information provided from the exchange, and then searches whether there is modem information for the caller's telephone number using the telephone number stored in the memory.

If there is the transmission side modem information as a result of the search, the modem is set to match the state of the modem information (Modulation Mode, Protocol Mode), and then the reception side information flag is set.

On the other hand, when the modem information of the other party's telephone number is not stored in the memory, the transmitter and receiver clear the transmitter and receiver information flags to perform modem information exchange process by training.

Then, if a modem connection for video communication is desired, when the modem connection button in the user interface is pressed, the system controller of the transmitting and receiving side attempts to connect to the modem and outputs a predetermined frequency (for example, DTMF tone) to the other party. It checks if they have mutual modem information.

That is, as shown in FIGS. 10 and 11, when the transmitter and the receiver have modem information on the other party's telephone number in the modem connection attempt state (Call Information Flag Set / Called Information Flag Set), In order to check and transmit a predetermined frequency (Call Frequency) through the communication line, the caller (Caller) is a state in which the sender information flag is set, that is, if there is a modem information on the receiver side predetermined predetermined request frequency (Request Frequency) Outputs to the caller within the set maximum set time (1Sec).

When the response frequency is detected by repeatedly detecting the answer frequency inputted from the receiver within the maximum set time (1 sec) and terminating the required frequency output, the training flag is cleared.

On the other hand, the receiver (Called) outputs a predetermined frequency (Called Frequency) to the transmitting side within the maximum set time (1Sec) in the state that the receiving information flag (Called Information Flag) is set, that is, the transmission modem information.

Then, the response frequency (Call Frequency) input from the transmitting side is repeatedly detected within the maximum set time (1Sec), and when the transmitting side response frequency is detected, the output of the required frequency is terminated and the training flag is cleared.

At this time, the predetermined request and response frequency signals output from the transmitter and receiver are selected from frequencies other than the frequencies used by the modem to output different frequencies, thereby preventing frequency malfunction caused by line echo. Do it.

On the other hand, if there is no modem information for the other party or if the other party's response frequency signal is not detected within the maximum set time (1Sec) even when the sending / receiving party outputs a predetermined request frequency signal, the transmitting / receiving party information flag is cleared. The modem information exchange process can be started.

Thereafter, as shown in FIG. 12, a training process for determining a communication speed is performed.

First, when it is confirmed at a certain frequency that the sending and receiving party has modem information about each other's telephone number, the modem speed is determined by training. When the speed is determined, data communication is started during the video communication period. .

In other words, if the training flag is cleared, the other party knows the mutual modem information. Therefore, training is performed to determine the transmission speed. After waiting for the connection at the proper transmission rate, communication is started in the video communication period. .

In addition, if there is no modem information for the other party's phone number and it is not confirmed with a certain frequency signal, the modem information for the other party's phone number is exchanged by exchanging the other party and the modem information, that is, Call Function, Modulation Mode, and Protocol Mode. It will be stored with the phone number in memory.

When the modem information of the other party is stored by modem communication, the modem transmission speed is determined by training, and when the modem transmission speed is determined, data communication is started in the video communication period.

That is, when the information flag is cleared and the training flag is set, the transmitting and receiving side performs a process of exchanging modem information between modems. After this process, the telephone number and modem information of the other party are stored together, and the next time the modem is accessed, The process of ITU-T.V8 is omitted and the training process (ITU-T.V34) can be performed immediately.

Therefore, during the video communication, the counterpart information stored in the memory may be checked within a maximum set time using a predetermined frequency signal, thereby omitting the modem information exchange process by the counterpart and the modem communication and immediately performing the training process.

Fourth Embodiment

13 to 16 show a name and a phone number in a video call, as a fourth dial of the present invention, when recording a phone number and a name as a speed dial of a video communication device, the video image is also recorded and editable. In addition, the user can easily search for the number to be dialed through the image.

In addition, by saving the image directly to the video communication device to save the memory of the video communication device itself by reinforcing the user interface when searching the phone book (phone book), and also supports a PC interface to store a lot of images Provides convenient phonebook management functions such as update or save playback, and provides convenience to users by using speed dials so that they can easily recognize and search the current contact person than when only the phone number and name are saved. It was.

Speed dial device using the image of the video communication device to be applied to the present invention; When the phone number and name are recorded so that the speed dial of the video communication device can be a video image, the data format including the video image is also stored in the memory 9 as a phone book image, and the system control section 8 And editing means (user interface) for modifying an image image of a data format stored in the memory 9 during the control operation of the controller.

In the data format stored in the memory 9, as shown in Fig. 13, a code value for recognizing the exchange of images is placed in a header, and the image information and the telephone number (Dial) having an image size, etc. Number) and an image image can be recorded simultaneously as compressed image data.

A PC may be connected to the control unit 8 via an RS232C interface to download a data format that is phonebooked and stored in the memory 9 and manage update, storage, and playback of an image image having a large capacity. have.

First, in order to match the image representing the other party with the ID (telephone number, communication mode setting information, etc.) of the corresponding party, as shown in Fig. 13, a code value for recognizing the exchange of the image is located in the header and Image information having information such as image size, telephone number (which may include communication mode setting information), and speed dial information of a format in which an image is recorded simultaneously as compressed image data are stored as a phone book image. ).

Herein, the information stored in the memory 9 is a portion in which an image image is stored (represented an image), a part having only a telephone number (represented by Dial Only), and a portion in which nothing is recorded, as shown in FIG. Display as separate).

Therefore, when the user displays the phone booked image stored in the memory 9 using the user interface 7 as shown in FIG. 14 and selects an image image to make a call, the user of the other party to make a call Even if a phone number or name is not found, video call with the other party is possible through a speed dial of the selected video image.

That is, when the user operates the speed dial key using the user interface unit 7 of the video communication device, the system control unit 8 displays the information stored in the memory 9 according to the operated speed dial key. Display the same image.

Then, when the user selects a desired image image from the displayed image image (indicated by a bold line in FIG. 14), the controller 8 stores the telephone number of the person to be dialed through the image image selected by the user. After performing the search in (9), the user accesses the searched phone number and executes the same connection control procedure as in the first, second, or third embodiment described above to enable a video call between the user and the other party. .

On the other hand, the information stored in the phone book and stored in the memory 9, in particular, the image image, can be edited.

For example, if an image image represented by a thick line is selected from the image images displayed as shown in FIG. 15 by using the user interface unit 7, the image selection as shown in FIG. 16 (a) will be made. When the user selects a mode for capturing an image of the counterpart displayed on the monitor 4 as a picture during video communication, the system controller 8 is currently displayed on the monitor 4 through the digital signal processing unit 3. The control operation of capturing the image of the image as shown in FIG. 16 (b) is executed.

In this case, when it is desired to store the photograph of the captured counterpart (b of FIG. 16), the controller 8 replaces the captured image of FIG. 16 (b) with the image of FIG. 16 (a). The memory 9 stores the memory 9 as shown in FIG.

On the other hand, the memory (9) for storing the image in the form of a phone book so that only a certain amount of images can be stored, it is possible to efficiently operate the memory of the video communication device itself.

That is, by connecting a PC to the controller 8 through an interface of RS232C for efficient operation of the memory 9, an image image desired by a user through the PC is not required even if the image of the person to be stored is not captured and recorded. Alternatively, a large amount of image images can be updated and stored or managed while playing.

That is, the controller 8 allows the user to download various types of image images in the PC through the interface of RS232C, thereby efficiently managing the memory capacity of the image communication device, and image images of the person that the user wants to store. Even if you do not record on the device, you can use the desired image as a speed dial.

According to the present invention, in executing the connection control of the video communication apparatus, the other party ID and the communication mode setting information corresponding to the ID are stored together in the memory, and the other party ID stored in the memory is the communication mode setting information corresponding to the ID. By omitting the modem information exchange process by using the and can immediately perform the training process to shorten the time to perform the video communication.
