Abstract

본 논문은 이종 무선망 환경에서 효과적인 영상 스트리밍 시스템에 대해 다룬다. 제안하는 영상 스트리밍 시스템은 파운틴 코드를 영상 스트리밍 서비스에 적합하도록 변형하고, 파운틴 코드의 지연 및 블록 복구 실패율 제약 조건들을 만족시키면서 다중 경로를 통해 영상 스트림의 비트율을 최대화한다. 마지막으로, 제안하는 시스템이 이종 무선망 환경에서 각 경로의 상태 정보를 기반으로 제어 변수를 동적으로 설정함으로써 고화질의 안정적인 영상 스트리밍 서비스를 사용자에게 제공할 수 있음을 보인다. In this paper, we propose an efficient video streaming system over heterogeneous wireless networks. The proposed system modifies fountain code for the video streaming service and maximizes the target video encoding rate using multiple paths while satisfying delay and block recovery failure rate constraints of fountain code. Finally, the proposed system provides the seamless video streaming service of high quality to subscribers by dynamic adaptation of control parameters based on the states of each path over heterogeneous wireless networks.
