Description

Data sorting transmission device in video telephone system

The present invention relates to a data transmitting / receiving device when an old video conference function of a video telephone system configured using a television is used. The present invention relates to an apparatus for sorting and transmitting data in a video telephone system for delivering the contents only to attendees.

In general, a TV / video telephone system includes a component for performing a TV function and a component for performing a video phone function as shown in FIG.

That is, in addition to a tuner 34 for receiving a broadcast signal, a video IC 30 for processing a video signal, an audio IC 32 for processing an audio signal, a CRT 31, and an SP 33, a TV talker is imaged. An image pickup means (10) for encoding a video signal and converting an audio signal into a digital signal, a modulator (21) for modulating the output of the image pickup means (10) to a high-speed transmission network, and A communication network interface unit 22 for outputting an output to a high-speed public network, and transmitting a signal of the other party inputted from the high-speed public network to a receiving end; and a demodulation device 27 for demodulating the received signal of the other party to reproduce video and audio signals. And an IF signal converter 28 for converting the demodulated video and audio signals to an IF signal of the TV, a DTMF generator 26 for generating a DTMF signal for calling the other party, and a key input of the remote controller 23. To send a phone number Group control of the DTMF generator 26, and is composed of a microcomputer 25 which controls the switching IC (29) to select an IF signal received during video telephone mode.

In such a TV / video telephone system, the TV mode and the video telephone mode can be selected according to the key input of the remote controller 23. In the video telephone mode, the microcomputer 25 controls the switching IC 29 to capture the received counterpart caller. A video and audio function was outputted through the cathode ray tube (31) and the SP (speaker: 33).

When conducting a video conference using the TV / video telephone system as described above, all the conference attendees who attend the video conference share all the video input through the image pickup device provided in front of any participant. The problem arises that there was no way to deliver a message (such as a confidential document or bid or a specific document that no one else could openly know).

An object of the present invention for solving the above problems is to use a time-slicing technique to deliver the contents only to a specific conference attendees if you want to send a message or video only to a specific party during the video conference The present invention provides a data sorting transmission apparatus in a system.

A feature of the present invention for achieving the above object is, in a video telephone system connected to a trunk line via a communication means such as a modem, and transmitting and receiving the image and audio read through a specific data reading means through the trunk line, the user An external device such as a scanner for receiving an image to be transmitted to a specific conference attendee, a text input key board for clearing a text to be transmitted to a specific conference attendee, and the external device or A selection unit for selecting a trunk line connection state for transferring data output from a text input key board to a specific conference participant, a modem control for controlling a modem according to the selection of the connection state selection unit, and a control by the modem control Output from the external device or the character input key board By time-sharing data through the modem is to include time-division transmission unit for transmitting to a particular conference participant.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

2 is a block diagram of a data sorting and transmitting apparatus in a video telephone system according to the present invention, which detects an audio signal from a modem 100 for connecting to a trunk line and a public communication network, and a signal input through the modem 100. The audio detector 110 outputs the audio signal from the audio detector 110, the amplifier 130 amplifies the audio signal output from the audio detector 110, and outputs the audio signal to the speaker SPK. A format converter 120 for converting the excluded data into a video signal form, and a video processor 140 for processing and outputting the data output from the format converter 120 in a form for displaying on a monitor (CRT). And a microphone (MIC) and a camera 80 that reads the voice and video of the current user and delivers the same to the modem 100, and inputs a video that the user wants to transmit to a specific conference attendee. Receiving an external device 41 such as a scanner, a character input key board 42 for clearing a character that a user wants to transmit to a specific conference attendant, like the external device 41, and the external device 41 or A mixer 43 for mixing and outputting data output from the character input key board 42, a connection state selecting unit 40 for delivering the data output from the mixer 43 to a specific conference attendee, According to the selection of the connection state selector 40, the modem control 60 for controlling the modem 100, and the data controlled by the modem control 60 and mixed through the mixer 43 are time-divided. The modem 100 is composed of a time division transmitter 70 for transmitting to a specific conference attendee.

Looking at the preferred operation of the data sorting transmission apparatus in the video telephone system according to the present invention configured as described above are as follows.

First, when there is data to be delivered to a specific meeting participant during a meeting, the user inputs information to be transmitted through the external device 41 or the text input key board 42 for the corresponding data. At this time, the status of the video or text input is not known to other conference attendees.

Data output from the external device 41 or the character input key board 42 is mixed through the mixer 43, and then the user is mixed through the mixer 43 through the connection state selection unit 40. It determines whether to transmit the data to a specific person through a modem to control the connection state selection unit 40 when the transmission is desired.

The modem control 60 for controlling the modem 100 according to the selection of the connection state selection unit 40 controls the time division transmitter 70 to inform the attendees selected through the connection state selection unit 40. The data mixed through the mixer 43 is time-divided.

When providing a data sorting transmission apparatus in a video telephone system according to the present invention operating as described above, all conference attendees attending the conventional video conference are all the video input through the image pickup device provided in front of any participant By sharing, we can solve the problem that there was no way to deliver a specific message to a specific person (such as confidential documents or bids or certain documents that others don't know publicly).
