Extension of SMIL with QoS Control and its Implementation

In this paper, we propose a language called QOS-SMIL where some QoS guarantee statements are added to a subclass of SMIL, and give its implementation technique. In QOS-SMIL, in addition to standard facilities of SMIL, (1) dynamic media-scaling of each multi-media object, and (2) explicit inter-media synchronization among objects, can be specified. In the proposed implementation technique, we use real-time LOTOS as an intermediate language so that we convert a given QOS-SMIL description to the corresponding real-time LOTOS specification, and implement it with our real-time LOTOS compiler. Through some experiments, we have confirmed that our approach has some advantages w.r.t. development cost of multimedia-systems with QoS control.
