Abstract(in English)	To improve media adaptiveness, we enhance a previously proposed network proxy, located at the junction of the wired network and wireless link, to provide timely feedbacks. The enhanced proxy is called Streaming Agent (SA). SA timely feedbacks provide partial path information for the server to track which packets have arrived correctly at SA. With this knowledge, the server can better adapt streaming content. We demonstrate SAs usefulness for the format-adaptation problem: two video streams with different I-frame frequencies are interchanged depending on SA and/or client feedbacks. We show that with SA feedbacks, visual quality improves up to 0.78dB at 230kbits/s.
