            Abstract : 
We address the problem of robust video transmission over unreliable networks. Our approach employs the principle of multiple-descriptions, through pre- and post-processing of the video data, without modification to the source or channel codecs. We employ oversampling to add redundancy to the original video data followed by a decomposition of the oversampled video frames into "equal" sub-images which can be coded and transmitted over separate channels. Simulations using two descriptions show that this approach maintains excellent reconstructed video quality when only one description is received
