Unequal Erasure Protection (UEP) is an attractive approach to protect data flows that contain information of different priority levels. The various solutions that have been proposed can be classified into three families. The first one consists of specific, UEP-aware FEC codes, that map the information dependency within the code structure. It enables to design a specific solution, valid for a specific data flow. However, because this is a specific solution, its practical interest is also narrowed.
