Query: Source Coding with Fixed Lag Side Information   We consider source coding with fixed lag side information at the decoder. We
focus on the special case of perfect side information with unit lag
corresponding to source coding with feedforward (the dual of channel coding
with feedback) introduced by Pradhan. We use this duality to develop a linear
complexity algorithm which achieves the rate-distortion bound for any
memoryless finite alphabet source and distortion measure.
