Abstract-- Multiple description coding addresses the problem
of encoding a source signal into two or more sub-streams. Each
sub-stream is assumed to be transmitted over an independent
path. However, multiple independent paths may not be available,
and for most cases only a single path can be used. The scheduling
of these descriptions over a single path is still problematic because
of the bursty packet loss behavior. In this paper, we propose a
novel packet scheduling method for multiple description coded
video transmission over a single path. The proposed method
adaptively schedules the descriptions according to channel condi-
tions by jointly considering the bursty packet loss behavior and
the transmission delay of the network. The simulation results
show that the proposed method can improve the video quality
by 1.5 dB on average as compared to the method of sending
