Multiple description motion compensation (MDMC) is a multiple description coding scheme which has shown good error resilience performance. This paper investigates the behavior of an MDMC video codec in a packet loss environment. A model for the decoder distortion induced by transmission errors is developed and their accuracy is validated by simulation studies. The model shows the necessity of coding mismatch signals in an MDMC codec. Also, a new mismatch signal coding method and the corresponding decoding strategy are presented which improves upon the original MDMC scheme in a packet lossy environment.
