Abstract

Adaptive modulation and coding (AMC), which is a technology used when channel condition changes, is adapted in mobile Worldwide Interoperability for Microwave Access (WiMAX). Scalable video coding (SVC) is a video coding scheme used for different users with bandwidth level. SVC encodes a video into a number of layers. Users receive different number of encoded layers based on their channel condition. In this paper, both AMC and SVC are employed to enhance the user perceived video quality in the system. Intermediate Control Server (ICS) is proposed to deal with the signaling between multimedia server and BS.
