Abstract

Various streaming technologies are being studied to guarantee the QoE of viewers due to the development of realistic media. HTTP adaptive streaming is a typical example, and it is based on HTTP / 1.1 and TCP. These protocols have become one of the causes of delaying the image delay and increasing the waiting time of web pages. Therefore, in this paper, we propose a QUIC-DASH system applying the UDP-based transmission protocols QUIC and HTTP / 2 to the MPEG-DASH system after analyzing various transmission protocols and development process of HTTP. Through experiments, the QUIC-DASH system confirmed the possibility of providing optimal performance in terms of transmission speed of LTE environment than existing system. We also suggest various future studies for better performance.

실감 미디어의 발전에 의해 시청자의 QoE를 보장하기 위해 다양한 스트리밍 기술에 대한 연구가 진행되고 있다. HTTP 적응적 스트리밍은 그 대표적인 예이며 HTTP/1.1과 TCP 기반으로 이루어져 있다. 해당 프로토콜들은 웹 페이지 대기 시간을 증가시키고 영상의 지연을 불어일으키는 원인의 하나로 대두되고 있다. 따라서 본 논문에서는 다양한 전송 프로토콜과 HTTP의 발전과정에 대해 분석한 후 UDP 기반의 전송프로토콜인 QUIC과 HTTP/2를 MPEG-DASH 시스템에 적용한 QUIC-DASH 시스템을 제안한다. 실험을 통해 해당 QUIC-DASH 시스템은 LTE 환경의 전송 속도 측면에서 기존의 시스템보다 최적의 성능 제공 가능성을 확인하였다. 또한, 더 나은 성능을 위해 다양한 차후 연구에 대해 제안한다.
