In our framework, layers of MPEG-4 video and FEC data are wrapped dynamically in RTP packets to pass through the heterogeneous network effectively. 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 effective and adaptive framework can be used to instruct the implementation of applications based on layered MPEG-4 video multicast transmission and other designs of multimedia application frameworks.展开更多

文摘An extensible framework was proposed to implement the hierarchical and adaptive control and feedback mechanism of layered MPEG-4 video multicast transmission in DirectShow architecture. In our framework, layers of MPEG-4 video and FEC data are wrapped dynamically in RTP packets to pass through the heterogeneous network effectively. 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 effective and adaptive framework can be used to instruct the implementation of applications based on layered MPEG-4 video multicast transmission and other designs of multimedia application frameworks.
