We propose a simple multiple description (MD) video coding technique motivated by human visual perception. This method employs two simple parameters to characterize the smoothness and edge features of DCT blocks and measure their perceptual tolerance against visual distortion. We duplicate the key components of compressed video and split the remaining according to the calculated perceptual tolerance parameter. Simulation results reveal that our simple MD video coding method achieves superior performance compared to other similar techniques which lack to consider the perceptual distortion in the design problem.
