Abstract
Forward Error Correction (FEC) coding is performed on data packets to generate verifying packets; corresponding information independent of a packet sequence number (SN) and denoting a corresponding relation between the data packets and the verifying packets is carried in the data packets, or in the verifying packets, or in the data packets and the verifying packets; the data packets and the verifying packets are transmitted by using a protocol based on a User Datagram Protocol (UDP). A method for receiving data packets and devices for transmitting and receiving data packets are further described. Thus, a receiving terminal correctly can recover lost data packets after a relay device modifies the packet SN.
