Recalling two FEC schemes for internet phone described. Suppose the first scheme generates a redundant chunk for every four original chunks. Suppose the second scheme uses a low-rate encoding whose transmission rate is 25 percent of the transmission rate of the nominal stream.
a) How much additional bandwidth does each scheme require? How much playback delay does each scheme add?b) How doe the two schemes perform if the first packet is lost in every group of five packets? Which scheme will have better audio quality?c) How doe the two schemes perform if the first packet is lost in every group of two packets? Which scheme will have better audio quality?
