Abstract

In this paper, we propose a protocol structure of a portable 4K Ultra High Definition (UHD) broadcast relay device that utilizes a 5G mobile communication network as a transport channel, and construct a prototype to conduct a broadcast relay performance test through a 5G mobile communication network. The test shows that the encoding time of the 4K UHD encoder is from a minimum of 86.28ms to a maximum of 88.41ms, the relay delay time in the 5G mobile communication network is 13.645ms on average, the delay variation is 17.49ms, and the glass-to-glass delay time is 289.90 on average, the delay variation is 27.63ms. Using the developed prototype, a relay test between Seoul and Anseong is conducted, and the possibility of 4K UHD broadcasting through a 5G mobile communication network is confirmed.

본 논문에서는 5G 이동통신망을 전송채널로 활용하는 휴대형 4K UHD(Ultra High Definition) 방송중계 장치의 프로토콜 구조를 제안하고 시제품을 구성하여 5G 이동통신망을 통한 방송중계 시험을 실시한다. 방송중계 시험을 통하여 4K UHD 인코더의 인코딩 시간은 최소 86.28ms 부터 최대 88.41ms 이며, 5G 이동통신망에서의 중계지연 시간은 평균 13.645ms, 지연변이는 17.49ms 이고 Glass-to-Glass 지연시간은 평균 289.90ms, 지연변이는 27.63ms로 측정됨을 확인한다. 개발된 시제품을 활용한 서을과 안성간의 중계 시험을 통해 5G 이동통신망을 통한 4K UHD 방송중계의 가능성을 확인한다.
