  Abstract

In recent years, various multimedia streaming services for mobile devices have been increasing. Also, the user demands for the higher quality of media services have been growing. In order to improve the quality of multimedia services, numerous researches on SVC (Scalable Video Coding) scheme, which supports heterogeneous mobile devices and various networks, and ARQ (Automatic Repeat reQuest) scheme, which recovers frame losses due to the unstable wireless channel conditions at MAC layer, have conducted. However, existing ARQ schemes do not guarantee the media qualities because these mechanisms do not consider the characteristics of scalable video coding techniques. In this paper, PA_ARQ (Priority-based Adaptive ARQ) scheme, a differentiated data transmission scheme to guarantee media quality, is proposed. PA_ARQ adaptively adjusts ARQ retransmission time based on the frame dependencies. PA_ARQ improves the quality of multimedia streaming services as it provides successful video decoding.
