In Video-on-Demand (V0D) services, the playback continuity is one of the most crucial factors for end-user to judge service quality. It is even more significant than the actual video image quality since new generation V0D users commonly have heterogeneous requirements on service according to their context. Moreover, managing dynamic situations in V0D service is always a challenge, especially in the unpredictable user preferences and network conditions. In this paper, i) Autonomous Decentralized V0D System (ADVODS) has been proposed to satisfy different service quality demands of users and, ii) the Autonomous Node Allocation Technology (ANAT) is proposed for assuring service continuity. With the help of autonomous nodes and mobile agents, ANAT can applies different backup policies to users with different Service Level Agreements (SLA), and dynamically update the backup schema to adapt the changing situations such as various service time or congestion events. Drawing on the evaluation results this paper shows that proposed system architecture has a better performance on streaming service provision and continuity.
