Abstract

In this paper, we propose "cross layer" design, such as swift-OFDM, low-latency packet-awareness coder and adaptive noise filtering design for wireless multimedia delivery. Unlike the conventional error correction code, we take the bursty nature of wireless Internet into our coder design consideration. Furthermore, we adoptively filter out noise based on image content so that we can reduce noise for least visual distortion. The experiment results show that the proposed design results in better video quality.
