Integration of QoS guarantees into SMIL and its flexible implementation

Abstract

In this paper, we propose a flexible implementation technique for QoS control mechanisms where they are implemented as separate modules using the constraint oriented style of real time LOTOS. For an application, we define and implement QOS-SMIL with: (1) dynamic switching, and (2) explicit inter-media synchronization facilities. Experimental results show that the proposed technique has some advantages with respect to development cost for QoS control mechanisms.
