Abstract

본 발명은 시각정보와 함께 전송되는 음성정보나 단독 음성정보를 실시간으로 송수신할 수 있는 공중전화망을 이용한 컴퓨터 통신 시스템의 실시간 음성정보 송수신장치 및 방법에 관한 것으로서, 음성코덱과, 실시간 데이타 압축/복원장치와, 모뎀으로 구성된 것을 특징으로 한다.The present invention relates to a real-time voice information transmission and reception apparatus and method of a computer communication system using a public telephone network capable of transmitting and receiving voice information or single voice information transmitted together with visual information. And a device and a modem.

본 발명에 의한 컴퓨터 통신 시스템의 실시간 음성정보 송수신장치 및 방법은 종래의 아날로그 음성신호 전송방식과는 달리 음성정보를 디지탈 음성신호로 변환하여 실시간으로 전송할 수 있으므로 시각정보와 음성정보를 실시간으로 동시에 전송할 수 있고, 많은 용량의 메모리부가 필요없게 되어 통신 시스템의 단가가 하강하며, 고중전화망의 상태에 따른 음질의 열화가 일어나지 않아 고음질의 통신을 제공할 수 있는 효과가 있다.The real-time voice information transmission and reception apparatus and method of the computer communication system according to the present invention can transmit the visual information and the voice information simultaneously in real time because the voice information can be converted into a digital voice signal and transmitted in real time, unlike the conventional analog voice signal transmission method. It is possible to reduce the cost of the communication system because it does not need a large capacity of the memory unit, there is an effect that can provide high-quality communication because the degradation of the sound quality does not occur according to the state of the high-end telephone network.
