In this paper, the structure of distributed remote video monitoring system (DRVMS) is introduced. When the compressed video is transmitted over error prone networks it can suffer severe interfering. So the error control strategies of resynchronization, data recovery and error concealment are discussed, and a novel temporal concealment method is adopted. This method improves the robustness of the DRVMS system. Simulation results, with an H.263+ codec and different video packet lost rate, show the satisfactory concealment performance of the adopted technique and suitable for real-time video monitoring system.
