Abstract

PURPOSE: An image telephone terminal having an image message processing and transmitting/receiving function is provided to process character data and a short message which is inputted to a digital image telephone terminal and store them in a memory. CONSTITUTION: A data converter converts an analog video/audio signal from a camera or a microphone into a digital signal. A key input section inputs a user key. A compressing/restoring section compresses a digital video/audio signal from the data converter and restores a compressed video/audio signal from a controller. The controller outputs the compressed video/audio signal from the compressing/restoring section. A memory stores short message data from the controller. A modem encodes and transmits data from the controller to a network and decodes and outputs data inputted to the network.

Description

Digital videophone that has a text message processing and transmission and reception function {Digital videophone that has the function for processing character message}

The present invention relates to a video telephony terminal device having a text message processing and transmission / reception function, and to converting video / audio / short message data (digital / analog conversion, coding / decoding, etc.) processing, compression, restoration, and controlling the same through a modem. It is a new video telephony terminal device that implements various text message transmission and reception functions as well as video calls by applying a technology of transmitting or receiving to a remote place. The ITU-T standard (H.324, H.320) for the conventional video telephony terminal device is a limited video communication standard that defines only the transmission and reception of video / audio data, and is emerging as a new communication method besides video and audio calls. Real-time text message transmission / reception in the OFF HOOK state using an existing analog phone has limitations of data storage, display, and various text expressions using DTMF analog signals. Therefore, the data utilization in various methods such as short message service is inferior, and it is a technology that can be implemented only in an analog connection state and thus cannot be used in a digital video telephone terminal device.

The present invention processes text data or short messages input to a digital-based video telephone terminal device by a user, stores them in a memory unit or transmits them through a modem, and separates text message data or short messages from data received through the modem. In order to perform the function of processing and storing it or outputting it to the display unit through data conversion, the character key input unit, the SMS processing unit, and the memory unit are separated from the data received from the modem for text transmission / reception and short message service. By implementing the data control function of the control unit to perform the operation such as output to the SMS processing unit to decode and store or display through the data conversion unit, various text communication such as digital data processing and transmission, short message service function, etc. Usability It provides a video telephone terminal device having.

The data converter converts analog video / audio signals received from cameras and microphones into digital signals and outputs them to the compression / restoration unit, or converts restored remotely received digital signals from the compression / restoration unit into analog and outputs them to the speaker and display unit. The compression / restore unit compresses the input digital data and outputs it to the control unit, and restores the compressed remotely received data received from the control unit and outputs it to the data conversion unit. The control unit adds the protocol for remote transmission of the compressed data received from the compression / recovery unit and outputs the compressed video / audio signal to the compression / restore unit by separating the remote reception data received by the modem unit. Outputs the data from the key input unit to the SMS processing unit for message transmission, receives the processed data, stores it in the memory unit or outputs it to the modem unit, separates the text signal from the remotely received data input through the modem unit, and outputs it to the SMS processing unit. It receives the processed data and stores it in the memory or outputs it to the data converter to display on the display.

The present invention provides a key input unit for inputting text for inputting a text message and a short message, a memory unit for storing text message data, coding key input text data for transmission, and received by a modem unit and separated by a control unit. SMS processing unit that performs the function of decoding outputted text message data, control unit for receiving and separating data signals and distributing and controlling them according to each flow and procedure, received and processed text data and memory It consists of a data conversion unit and a display unit that display the stored short message, etc. Each of these modules is a modem unit that is responsible for transmitting and receiving data signals for digital video / voice communication, and the control and conversion of data It works in conjunction with a configuration module of a video telephone terminal such as a control unit and a data conversion unit.

According to the present invention, the video phone terminal device can implement various text communication functions such as message communication and short message service using text in addition to the existing video / audio using only the function of the terminal device itself without any external service, and based on digital data communication. Utilizing the advantages of video terminal devices, it is possible to send and receive various text messages, digital video calls, and real-time text chat functions and text data, ranging from Korean, English, numbers, and various special symbols, which cannot be implemented in existing analog phones. The storage and implementation of a short message service using the same can be immediately implemented by connecting only terminal devices of the present invention in an existing telephone network, and technically, a short message service (SMS) of the terminal device of the present invention connected to a general telephone line and a digital mobile phone. ) Or PC Instant Mesh Services such as messaging, data exchange, etc. can be a variety of additional applications.
