Abstract

Hierarchical video allows to send different qualities of flow to clients from a single video file located on a server. Light clients (such as PDA) can’t display this kind of video because of the lake of computing resources to decode (aggregate layers) the video in real-time. That’s why we propose to distribute this aggregation on active nodes located along the video flow path between the video server and the light client (each active router decides independently to process packets). To achieve this the best way, we make our protocol respectful of others traffics in guaranteeing them a minimum part of active node resources. In order to guarantee some QoS level, active nodes check their resources and their interface congestion. Thus, in case of overloaded active nodes, they contact the video server to decrease the quality of the video to ease the network. This allows a hierarchical video to be displayed on a PDA with the best quality without disturbing others traffics.
