TV and Video Broadcasting Framework for Mobile Networks

Video Multicasting

The work on multimedia over wireless mesh networks has inspired us to explore other wireless transmission standards. For this reasons, we have chosen IEEE 802.16 (WiMax). In this work a test bed experiment is designed to demonstrate the framework on the Cross-Layer Superposition Coded Multicast for Robust IPTV Services over WiMAX. The Goal of this experiment is to transmit scalable video by Super Position Coding (SPC) to demonstrate different video quality will be received under different wireless channel quality. If the channel quality is good enough, enhanced quality video can be received. If the receiver signal is not strong enough, at least the base quality video can be played. The Scalable Video is encoded by JSVM 9.18 developed by Heinrich Hertz Institute. The generated video is extracted into 2 layers, Base and Enhancement by BitStreamExtractor developed by us. The testbed consists of two emulators. Two PCs are connected to the emulators by LAN cable. The emulators are connected by RF cables through a variableattenuator from up converter on transmitter to down converter on receiver. We are also working on extending this work to tackle experimenting transmitting scalable video over different channel widths. Below is a screenshots of our testbed results, where the left image shows GM at 10dB (Average PSNR: 42.3dB), middle image shows SCM (= 0:7153) at 10dB (Average PSNR: 58.8dB), and the right image shows SCM (= 0:7153) at 14dB (Average PSNR: 48.7dB).
