Abstract

The present invention provides a network-based real-time video transmission method, comprising: 1) caching, by a transmitting terminal, an already transmitted original data packet, and recording the transmission moment of the original data packet; 2) counting, by a receiving terminal, lost data packets and current real-time network condition information and feeding back these information to the transmitting terminal; 3) constructing, by the transmitting terminal, a retransmission data packet according to the cached lost data packet using a variable-code forward error correction technology, and transmitting the retransmission data packet to the receiving terminal, wherein the error correction rate of the retransmission data packet is determined according to the remaining lifetime of the lost data packet and the real-time network condition information; and, 4) receiving, by the receiving terminal, the retransmission data packet and recovering the lost data packet.
