Generalized Multiple Description Coding Through Unequal Loss Protection

We use unequal amounts of explicit channel coding for generalized multiple description coding. Our solution can use any progressive source coder and it disperses information equally among the descriptions. Image quality improves gradually with the number of received descriptions. Our approach surpasses previously published results by a signi cant margin.
