Abstract
An extensible framework was proposed to implement the hierarchical and adaptive control and the feedback mechanism of layered MPEG-4 video multicast transmission in DirectShow architecture. In the framework, layers of MPEG-4 video and FEC data are wrapped dynamically in RTP packets to pass through the heterogeneous network. An adaptive control center is designed to control the actions of the related components dynamically according to varying resources availability on local host and network. This adaptive framework can be used to instruct the implementation of applications based on layered MPEG-4 video multicast transmission and other design of multimedia application frameworks.
