When　transmitted　over　error-prone　environments,　the　stereoscopic　video　data　may　undergo　transmission　errors　and　loss.　In　order　to　improve　the　quality　of　the　reconstructed　video,　a　Joint　Multi-view　Coding　(JMVC)　based　error　concealment　method　for　stereoscopic　video　is　proposed　in　this　paper.　In　this　method,　the　errors　in　the　independent　view　are　concealed　by　traditional　two-dimensional　(2-D)　video　error　concealment　algorithm.　For　the　lost　macroblock　(MB)　in　the　dependent　view,　intra　and　inter-view　correlation　are　utilized　to　conceal　the　errors　based　on　the　characteristics　and　its　coding　mode　of　the　stereoscopic　videos.　Combined　with　related　reference　MBs＇　partition　mode,　the　lost　MBs　are　divided　into　two　types:　smooth　block　and　texture　block.　Smooth　block　is　to　be　processed　by　improved　Boundary　Smooth　Degree　(BSD),　while　reconstruction　of　texture　block　is　done　by　unit　of　8×8　block　with　related　pixel　Sum　of　the　Absolute　Differences　(SAD).　Experimental　results　show　that,　compared　with　the　conventional　error　concealment　methods　for　stereoscopic　video　coding,　the　proposed　method　can　achieve　better　subjective　and　objective　performances.
