A novel approach named priority encoding transmission (PET) was proposed to guarantee delivery of the highest-priority data and/or the timely recovery of real-time data in the transmission of multimedia information over lossy networks. We propose a methodology to determine the fractions of the packets sent that are needed at the receiver to meet the QoS loss requirements specified by the user. It allows the mapping of the required segment loss probabilities on the corresponding parameters of the PET system. As a relevant case study, the proposed methodology has been applied to the transmission of MPEG video signals over an ATM network using PET
