This paper proposes an adaptive mode switching for error resilient video coding. The error resilient video coding system dynamically replaces reference pictures in inter-frame coding according to backward channel signaling. This system prevents temporal error propagation by preventing the encoder from using the erroneous picture as the reference picture. This system has two modes ; the ACK mode is effective in more erroneous condition, and the NACK mode is effective in less erroneous condition. The mode switching mechanism and the error condition on the network is explained, and the performance of the system compared with the conventional H.263 system is shown by computer simulation.
