In a thin client system which provides a high-quality picture reproduction method and which makes it possible to use a thin client terminal as a TeleVision (TV) phone terminal and a TV conference terminal, a video reproducing module is disposed in a thin client server device and a graphics module is disposed in a thin client terminal. The thin client server device sets a transmission color to a video display area of screen data and sends the screen data via a remote control communication path and simultaneously sends video data via a second route. The thin client terminal receives the screen data and the video data and displays the screen and video data as an overlay image in one same screen using the screen overlay scheme.
