Abstract

본 발명은 개인용 컴퓨터의 엠피이지(MPEG:Motion Picture Experts Group) 카드장치에 관한 것으로, 특히 일반전화선을 이용하여 압축된 동화상신호를 수신하여 티브이를 통하여 방영할 수 있는 주문형 비디오(VOD)시스템이 개인용 컴퓨터를 이용하여서도 가능하도록 한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a MPEG (Motion Picture Experts Group) card device of a personal computer. In particular, a video on demand (VOD) system that receives a compressed video signal using a general telephone line and broadcasts it on a TV is used for personal It is also possible to use a computer.

종래 개인용 컴퓨터의 MPEG 카드장치는 씨디롬과 같은 MPEG 압축데이타를 읽어들여 원래의 신호로 복원시켜 모니터 및 티브이로 디스플레이할 수 있었으나, 사용자가 원하는 시기에 영상서비스 또는 각종 통신서비스를 받을 수 있도록 하는 주문형 비디오의 셋탑카드장치의 기능을 구현할 수는 없었다.Conventionally, the MPEG card device of a personal computer can read MPEG compressed data such as a CD-ROM, restore it to an original signal, and display it on a monitor or TV. However, video on demand or various communication services can be provided when a user desires. Could not implement the functionality of the set-top card device.

본 발명은 상기와 같은 문제점을 해결하기 위하여 주문형 비디오의 셋탑카드장치의 기능을 개인용 컴퓨터의 MPEG 카드장치를 이용하여 전화선을 통하여 수신된 압축된 동화상 신호를 원래의 신호로 복원하여 모니터 또는 티브이로 디스플레이될 수 있도록 하므로서, 개인용 컴퓨터를 이용하여서도 주문형 비디오와 같은 영상서비스 및 통신서비스를 제공받을 수 있도록 한 것이다.In order to solve the above problems, the present invention restores the function of the set-top card apparatus of video on demand to the original signal by restoring the compressed video signal received through a telephone line using the MPEG card apparatus of a personal computer. In order to be able to do so, it is possible to receive video and communication services such as video on demand using a personal computer.
