Disclosed are an anti-packet-loss real-time communication method, system and related device based on hierarchical coding. A transmitting end initially sets a coding parameter and a packetization parameter according to a network condition difference, and generates a load containing coded data and protected data simultaneously according to the coding parameter and the packetization parameter and transmits same to a receiving end; the receiving end calculates a network status parameter according to the received load and transmits same to the transmitting end; and the transmitting end adjusts the coding parameter and the packetization parameter in real time according to the network status parameter, and generates a load of the coded data and protected data simultaneously according to the adjusted coding parameter and packetization parameter. The present invention performs self-adaptive processing on packet loss or congestion occurring in a network during real-time communication, i.e., adjusts the code rate and transmission position of protected data in real time according to network conditions, so as to effectively prevent a discontinuous sound, image mess or pause phenomenon occurring at a client, thereby improving the user experience. |
