Adaptive DirectShow Framework for Layered MPEG-4 Video Multicast

摘要

An extensible framework was proposed to implement the hierarchical and adaptive control andfeedback mechanism of layered MPEG-4 video multicast transmission in DirectShow architecture. In ourframework, layers of MPEG-4 video and FEC data are wrapped dynamically in RTP packets to pass through theheterogeneous network effectively. An adaptive control center is designed to control the actions of the
