Abstract It is very common that the packets may be lost over IP networks during transmission. The scheme proposed in this paper involves a novel erasure correcting code, a packet sending order and error concealment method. The [9,5,3] erasure correcting code in this paper has excellent lost recovering capability, linear encoding and decoding time and is easily constructed. The packetization method increases the capability of error resilience against the burst packet loss. The error concealment tool FMO of H.264 is used to deal with the video information packet that can not be recovered.
