In this paper, we propose a novel proxy-based hierarchical gateway scheme to optimize receiver adaptation layered video transmission in multicast scenarios. The proxies within networks are defined as transport layer gateways to coordinate senders and receivers. By using the proxies, the receiver adaptation for diverse bandwidth networks is synchronized. Additionally, we also incorporate embedded codecs into the structure of layers to perform hybrid scalable video coding. From cooperation between transport layer proxies and application layer hybrid codecs, the proxy scheme improves the scalability of the network and provides a solution to heterogeneous video requirements among receivers
