Digital　shadow　play　is　one　attempt　to　combine　the　traditional　shadowgraph　and　modern　computer　science　technology.　By　the　requirement　of　shadowgraph　in　the　real　world,　the　digital　shadow　play　is　required　to　be　highly　real-time,　easily　handle　and　strong　interaction.　Besides,　because　of　the　requirement　of　multi-personal　interaction,　the　design　and　implement　of　communication　model　also　should　be　considered　in　the　digital　shadow　play　system.　In　this　paper,　it　proposes　one　flash-based　digital　shadow　play　communication　module,　which　utilizes　socket　to　achieve　the　requirement　of　fluent　communication　between　multiple　digital　shadow　play　clients.　Then　the　communication　model　will　be　used　in　the　digital　shadow　play　system.　©　2010　IEEE.
