3DTV streaming over Peer-to-Peer networks using FEC-based noncooperative multiple description

Recent works have shown how Multiple Description Coding (MDC) and Peer-to-Peer transmission protocols prove to be extremely helpful in streaming video sequences. The quality of the reconstructed sequence can be significantly improved by differentiating the Quality-of-Service levels via distributed packet classifications performed by each peer independently. The packet labelling can be modelled via noncooperative games where the different uploading nodes are players/descriptions competing for the available network resources. The paper shows how this framework can be effectively employed for the transmission of 3D video sequences adopting an FEC-based multiple description scheme that encapsulates different kinds of data streams (color information, geometry) into a set of equally-important packets. Experimental results show that the classification strategy based on game theory improves the quality of the reconstructed sequence with respect to standard classification strategies.
