This paper describes cross-layer optimization strategies and simulation results for H.264 videomulticast over wireless LAN. The proposed scheme takes into account the varying channe conditions of multiple users, and dynamically allocates available bandwidth between source coding and channel coding. In particular, source coding parameters (intra update and quantization) and application-layer FEC code rate are chosen jointly to optimize a multicast performance criterion, based on feedbacks from all multicast receivers. Two performance criteria for video multicast are investigated and compared.
