EAFR-based DLNA proxy for high-quality video distribution in extended home space

We propose a DLNA proxy^* for home-to-home content distribution that enables a source DLNA-compliant device to multicast a high-quality video to target ones in different UPnP-enabled home networks by applying a large-scale media distribution scheme to the DLNA architecture. The proposed EAFR scheme helps the DLNA proxy efficiently distribute overall network traffic load for a massive content delivered to the DLNA devices placed on different home networks by utilizing unused forwarding bandwidth on delivery paths, among them based on a multiple multicast trees approach.
