In this paper, we attempt to overcome the limitation of specific scalable video codec and apply FEC-MDC to a common video coder, such as the standard H.264. The proposed scheme is explained as follows. Firstly, according to motion vector changes, an original video sequence is divided into several sub-sequences as messages, so in each message better temporal correlation can be maintained for better estimation when information losses occur. Secondly, the standard H.264 encoder is used to encode the messages. Thirdly, based on priority encoding transmission, unequal protections are assigned in each message. Lastly, at the decoder, the segments whose priorities are not higher than the fraction of packets received can be recover totally.
