2011 JUN 1 - (VerticalNews.com) -- According to recent research from Chungnam,rnSouth Korea, "The conventional hybrid method of block truncation coding (BTC) andrndifferential pulse code modulation (DPCM), namely the DPCM-BTC method, offers better ratedistortionrnperformance than the standard BTC. However, the quantization error in the hybridrnmethod is easily increased for large block sizes due to the use of two representative levels inrnBTC."
