| Summary: | 碩士 === 國立成功大學 === 資訊工程學系 === 86 === The Internet explosion is driving the need for group multimedia
applications,which provide multiple users with contented
multimedia services, e.g., videodistribution and distance
learning. The provision of group applications ismostly based on
multicastcommunications, which can reduce the consumption of
network resources. However, the characteristics of multicast and
the delivery of multiple media streams induce many new problems
in the design of networking architecture and system, and media
synchronization controls. Thus, a communication engine, which is
called Mcast, that can achievesmooth multimedia presentations
with the temporal relation preservation amongmultiple media
streams is proposed and developed. In this thesis, major issues
involved in the design andimplementation of Mcast, such as
multicast communication architecture andsynchronization control
schemes for multiple-streams presentations, are discussedand
resolved. According to the proposed communication architecture
and synchronization control schemes, Mcast can be the middleware
of multicast multimedia applications to smoothly present
continuous and static media.
