Abstract

In this paper, we designed and implemented a mobile video transmission device with 1080i resolution and 30fps frame rate using wireless multi-access technologies. The video acquisition delay time of 16us and jitter of 21ms for this equipment were obtained, respectively. The device is designed to access various communication networks. In order to evaluate the performance of its video transmission capability, a server and monitoring viewer are implemented. In the performance test using LTE network, 211ms delay time was obtained at 3Mbps transmission. Rendering of 1fps frame rate at the 265kbps transmission was confirmed for the transmission test using Inmarsat network.

본 논문에서는 무선 다중 접속 기술을 이용하여 1080i 해상도와 최대 30fps 프레임레이트를 갖는 휴대용 동영상 전송 장치를 설계 및 제작하였다. 이 장치의 영상획득 지연시간은 16us이며 지터는 평균 21ms이다. 이 장치는 다양한 통신망에 선택적으로 접속이 가능하도록 설계하였으며 전송 시험을 위하여 서버와 관제를 위한 뷰어를 구현하였다. LTE망을 이용한 전송실험의 경우, 3Mbps 전송 시 211ms 지연시간을 타나냈으며 인말새트 위성망을 이용한 실험에서는 265kbps 전송 시 1fps 프레임레이트로 렌더링되는 것을 확인하였다.
