Abstract
A method for protecting video transmission based on H.264 is disclosed, In the invention, a receiving end performs statistical analysis on the communication quality and the result is fed back to a transmitting end, the transmitting end adjusts the protection strategy self adaptively; the receiving end performs statistical analysis on the accumulated lost slice rate and position information about lost data based on the discontinuous situation of NALU sequence numbers; the receiving end feeds the statistical information back to the transmitting end with extended SEI message; the transmitting end configures two sets of protection strategy systems to separately protect critical data and non critical data, and selects the protection strategy of appropriate level according to the accumulated lost slice rate that is fed back; the receiving end transmits position information about lost data back to the transmitting end; the transmitting end resends the lost data.
