Abstract

As demand for the application in multimedia networks is increasing rapidly, it is important to provide these services in Mobile Environments (ME). Obtaining to multimedia services which satisfy synchronization constraints in ME and improving the delay time and Quality of Service(QoS) between media streams to be presented, new specification model has to be proposed. In this paper we propose Mobile Synchronization Model(MSM) as a new specification model for describing efficiently the QoS and the delay time. Also, we propose the multimedia synchronization algorithm where is a dynamic synchronization method that minimizes the effects of adaptive transmission delay time. The proposed model has higher the guarantee of QoS such as the loss rate and the playout rate than it of the previous work.

멀티미디어 네트워크상의 응용의 요구가 빠르게 증가함으로써 모바일 환경의 서비스를 제공하는 것이 중요하다. 모바일 환경에서 동기화의 제약조건을 만족하는 멀티미디어 서비스를 얻고 미디어 스트림 사이에서 지연시간과 서비스 품질을 개선시키기 위해서는 새로운 규격 모델이 제안되어져야 한다. 본 논문에서는 효율적인 서비스 품질과 지연시간을 서술할 수 있는 새로운 규격 모델로써 모바일 동기화 모델을 제안한다. 또한 적응적인 전송지연 시간의 효과를 최소화할 수 있는 동적인 동기화 방법인 멀티미디어 동기화 알고리즘을 제안한다. 제안된 모델은 기존의 연구보다 손실율과 재생률과 같은 서비스 품질을 향상시켰다.
