The document discusses a study on using Scalable Video Coding (SVC) tunneling for media-aware content delivery. SVC can save bandwidth for multicast content delivery but many devices do not support SVC natively. The study proposes using SVC tunneling only for delivery, with transcoding at ingress and egress points. The study tests transcoding MPEG-2 video to SVC and back to MPEG-2, finding a peak signal-to-noise ratio drop of 2.1 dB and 43% lower bandwidth requirements compared to MPEG-2 simulcast. Future work could analyze different video formats and implementations of SVC.
