Abstract

There are increasing demands for the transmission of high speed and non-compressed video informations. The video data usually compressed before transmission for reducing the data. And the received data uncompressed at a receiver, consequently the processing delay is unavoided. In this paper, we implement a 60 GHz band wireless transmission system for real time multimedia contents transmission, and successfully transmit the full HD class uncompressed video information at 4 Gbps with 20 m apart. Hence the non-compressed video data from a remote camera or a smart phone can be transmitted and displayed in a large screen in real time via the developed transceiver system.

멀티미디어 시대에 들어서면서 고속의 무압축 영상 정보 전송의 요구가 증가하고 있다. 그동안 영상 정보는 전송하기 전에 데이터량을 줄이기 위해서 압축하여 전송하였고, 수신 후 다시 압축을 해제하는 과정에서 프로세싱 지연이 있었다. 그러나 본 논문에서는 실시간 멀티미디어 컨텐츠 전송용 60 GHz 대 무선 송수신 시스템을 제작하였고, 실내에서 20 m 떨어진 거리에서 4 Gbps의 전송속도로 Full HD급의 영상을 무압축하여 성공적으로 송수신하였다. 따라서 개발한 송수신 시스템으로 원격지의 카메라 영상 또는 스마트 폰 멀티미디어 콘텐츠를 무압축하여 실시간으로 대화면에 무선으로 전송할 수 있게 되었다.
