'''Multiple Description Coding''' is a coding technique which codes a single media stream into minimally two independent descriptions. Any, or an arbitrary combination, of these descriptions on the decoder side are used to reconstruct the media stream. Quality improves with the number of descriptions correctly received. Its main advantage, over real-time single description (SD) video coding, is its robustness to errors in an unreliable network.

A general example of a MD coding system with two descriptions is given in the figure.
