Description

How to check incoming call response and received voice during data communication

The present invention relates to a method for confirming an incoming call and receiving a voice during data communication, which enables to selectively receive an external telephone call during communication. More specifically, another telephone call is received from a telephone exchange during communication. It detects and displays it, and selectively responds to incoming call during communication according to user's request or communication status, saves caller's voice message, and returns to communication status, and when communication is terminated, automatically receives voice signal received during communication. The present invention relates to a method of confirming incoming calls and receiving voice during data communication.

As Internet communication is becoming more common and information retrieval is actively used, development of TVs with Internet functions has begun. Recently, development has been completed and it has started to appear as a product. As such, the TV with built-in Internet function adds a set-top box-type internet terminal to the existing TV and connects it to the telephone line, so that anyone can experience the world of information through the Internet comfortably through the TV screen. I could do it.

However, since the Internet communication provided through the set top box shares the telephone line through the switch with the telephone, when the caller from the outside tries to connect with the communication user through the telephone during the communication using the set top box. However, since the communication user's channel is already used as a data communication channel, the subscriber receives a signal to inform the user that the call is busy or the subscriber who has been applied for the call waiting service. It will be sent out from the exchange.

However, even if a waiting sound is received during communication, the set-top box during communication is recognized as a data signal out of the protocol, which causes an unexpected data error, and does not recognize that a separate call is held by such waiting sound. Since it was unable to answer another call during communication using a set-top box sharing a single telephone line, the caller requesting the call only gave a frustration, and the communication user could not answer an urgent call. .

Therefore, the present invention was created to solve the above problems, and during the communication using the set-top box, the incoming call response during data communication to recognize the incoming call from the outside and to selectively respond to the call state to process the incoming call. The purpose is to provide a method.

In addition, another object of the present invention is to provide a voice confirmation method received during data communication that can automatically confirm the caller voice signal received and stored by the incoming call recognized during communication at the end of the communication connection using the set-top box will be.

In the method of receiving incoming call response and receiving voice during data communication according to the present invention as described above, when receiving an incoming signal indicating that there is a waiting call from the outside during communication using an exchange line, it detects this and is currently waiting. Generates an on-screen signal indicating that there is a call and outputs it to an external video device connected to it, and performs a voice call with the caller in response to a standby call when there is no influence of data transmission and reception according to the current communication state, or The voice signal of the received caller is stored, and when the call or storage is completed, the caller returns to the standby communication channel.

In addition, when the communication is terminated after returning to the communication channel as described above, it detects this and confirms the presence or absence of the stored telephone voice signal during communication, and when the existence of the received telephone voice signal is confirmed, the stored caller's voice signal By reading the and transmitting the read audio signal to the audio input terminal of the external video device, the user can automatically listen to the audio signal that the voice was not confirmed during communication.

Hereinafter, preferred embodiments of an incoming call response and a received voice confirmation method during data communication according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a preferred embodiment of a set-top box in which an incoming call response and a received voice confirmation method are implemented during data communication according to the present invention, wherein a voice support modem 101 is connected to a telephone line to perform communication; An amplifier 301 for selectively amplifying the input signal through the microphone Mic; A standby sound detection unit 100 for detecting a standby sound during communication during communication; An A / D converter 201 for converting a received caller voice signal into digital data; A memory 210 for storing voice data and visual data; D / A converters 202a and 202b for converting the stored voice data into voice signals; An OSD (On Screen Display) unit 240 for converting input data into on-screen signals; A video signal converter 241 for converting input data into video signals; A timer 250 for tracking and keeping a current time; And a controller 200 for controlling the operation and data movement of the component according to the standby detection of the standby sound detector 100 during a call.

2 is a flowchart of a method for confirming an incoming call response and a received voice during data communication according to the present invention. Hereinafter, the flowchart of FIG. 2 will be described in detail with reference to the configuration diagram of FIG. 1.

While the user is communicating while watching the TV receiver using the Internet set-top box having the configuration as shown in FIG. 1 connected to the exchange (S10), an external caller requests a call and the call waiting signal through the exchange. When the 350Hz + 440Hz signal of the 4-second period is transmitted, the standby sound detection unit 100 extracts the standby sound signal band and compares the level of the extracted signal with a reference value to transmit the comparison result value to the control unit 200. In operation S20, the controller 200 recognizes that there is another call request during communication based on the comparison result, and transmits data indicating that there is a call waiting to the OSD unit 240. The OSD unit 240 converts the input data into an on-screen signal and transmits the data to an external TV video input terminal, thereby additionally indicating that a call from the outside is received on the TV receiver displaying the current communication state. The user is informed (S21).

On the other hand, the controller 200 checks the current communication state, that is, the data transmission and reception state (S30), and if there is no data reception after data is received for a predetermined time, the user searches by scrolling the screen of the received and stored data. It determines that it is being performed to control the modem 101 to generate a hook-on signal instantaneously to switch the connection state (S31), as described above to notify the communication user through the OSD unit 240.

In the mode that does not automatically switch the connection state as described above, whether the user who checks the standby of the displayed call switches the communication state currently performed according to the current communication mode (file transmission / reception, chat, intermittent search, etc.). After determining that, when requesting the modem 101 to switch the communication standby state (S30), as described above, by sending a hook-on signal of the moment, the exchange switches the current communication channel to the standby state (S31), Allows you to connect a call on hold.

When the user requests a direct call with the caller through the connected telephone channel in response to the waiting call as described above (S40), the controller 200 enables the operation of the amplifier 301 to enable the microphone (Mic). The amplified voice is transmitted to the other party, and the caller's voice is digitally converted by the A / D converter 201 and stored in the memory 210, and the D / A converter 202a is again By reconverting to an analog audio signal through the voice input terminal of the external video device, a direct call with the caller is performed (S41), and when the user only wants to store the audio signal received through the call channel to which the user responds, The controller 200 transmits an auto-response message previously stored in the memory 210 (S44). When the caller transmits a voice signal in response thereto, the controller 200 transmits the A / D converter 201. To At the same time, the digital voice data is stored in the memory 210 and the current time of the timer 250 is read and stored together (S45).

In addition, when the communication user requests only the voice storage without a direct call, the control unit 200 not only updates the number of voice stored calls by updating the number of voice stored calls during communication (S46), but also the user's search request. At the time, the communication data contents previously received and stored in the memory 210 are selected according to the request and transmitted to the video signal converter 241 so that communication data can be searched through the TV screen during a call. )

After this process, the control unit 200 causes the modem 101 to instantaneously generate a hook-on signal to return the communication channel, which has been switched to the standby state, to its original state (S43), thereby allowing the user to terminate communication. Communication is continued using the set top box until desired (S50).

When the user terminates the communication after the waiting call response process as described above (S50), the control unit 200 checks the number of the updated response waiting call (S51) and at least once (S52) automatically. The OSD unit 240 and the TV video input terminal outputs a message indicating whether to check the stored call waiting time and the contents of the call received during communication, and asks whether the user listens (S53). When the request is made, the voice message stored in the controller 200, i.e., the reception time is displayed on the TV receiver through the OSD unit 240 and the TV image input terminal (S61) and the memory 210. By transmitting the voice message of the caller corresponding to the displayed time stored in the voice signal to the TV audio signal input terminal through the D / A converter 202a (S62), the user through the TV speaker Is stored to listen to the voice of the process is stored waiting call number until the end, or until the user termination request is presented proceeds to (S70) sequentially (S71, S61, S62, ...).

In the data communication according to the present invention, the incoming call response and the received voice confirmation method according to the present invention, during the communication using the Internet set-top box, detects the waiting call during the call and selectively responds to the waiting call according to the communication state, By recording only the voice of the other party as well as the voice call with the other party without ending the call, the caller who answered the call is no longer frustrated or unnecessary unnecessary waiting time is eliminated even during the long time communication. By automatically confirming the voice signal, it is a very convenient and useful invention to further improve the efficiency of the communication line to respond quickly to the urgent caller voice signal received during communication.
