Abstract :
In this paper the problem of transmitting embedded bitstreams over wireless packet networks is considered. In particular, the authors address the problem of joint usage of power control and forward error correction for optimizing video streams delivery, and analyze the performance in different scenarios. Experimental results, obtained for the transmission of MPEG-4 FGS bitstreams, show the impact of the proposed method in the case of different modulation schemes.
