	Modeling and Optimization of PET-Redundancy Assignment
			  for MPEG Sequences
			  ICSI TR-95-018

	Priority Encoding  Transmission (PET) is an encoding scheme
	which provides multiple  levels of  redundancy in order  to
	protect the different contents  of a data set  according to
	their  importance.  The     task of   optimally   assigning
	redundancies for   the PET encoding scheme  is investigated
	for the special  case  of MPEG-1 encoded video   sequences.
	The prerequisites for this optimization problem and the way
	of proceeding  for its  solution are  outlined  and several
	suggestions for further improvements are given.
