MPEG-21 Based Adaptation for Scalable Video Streaming
Yuanting Yang · Journal of Xiamen University · 2010
In this article,we describe a ubiquitous MPEG-21 based scalable video streaming system.Its main feature is to support seamless communication.The system enables wireless devices to roam among different wireless networks without breaking the ongoing connections.The method of video coding can adaptively adjust to match the significant change of wireless link characteristics due to vertical handoff.A proof-of-concept solution distributed DIA is proposed,for more complex adaptation scenarios through cooperations among the server and proxies.The system designed in the paper is illustrated successfully to achieved the implementation of the vertical handoff without disconnecting the ongoing connections.
