Video Transmission for Mobile Wireless
... Paired with low delay and high capacity, 3G-LTE enables HDTV SVC video broadcasting in urban deployments. In general, we can conclude from our experiments, that in particular the nature of the fading channel matches well with the mechanism of H.264/Scalable Video Coding (SVC). Challenges Real-time ...
