摘要

In this paper, an adaptive framework to guarantee the application quality of service (APQoS) of World Wide Web Consortium (W3C) Synchronized Multimedia Integration Language (SMIL) presentation is proposed. This framework cooperates with underlying network protocol stacks and SMIL client/server applications to guarantee continuous playback without interruption for the streaming video and audio objects in the SMIL presentation. The framework at the SMIL client periodically monitors underlying network bandwidth to calculate if synchronization requirements of the SMIL presentation can be satisfied. If not, the framework will first try to dynamically adjust bandwidth allocations among concurrent SMIL objects, according to their Media Importance (MI) values, at the SMIL media servers. If this scheme fails, other strategies, such as discarding less important objects or sending lower bitrate objects instead, are provided. The ATM Available Bit Rate (ABR) service is used in this paper to provide adaptive QoS support of network transmission due to its inexpensive cost. From simulation results, this framework guarantees all media data in the SMIL presentation can be shown synchronously.
