Abstract
For the purpose of digital recording of HDTV signals (EUREKA standard, 1250/50/2:1) a codec has been realized (HDI-codec) which can reduce the initial data rate from 1.152 GBit/s down to one fifth. According to the desired reduction, the playtime of a digital VCR (video cassette recorder) can be increased from about 40-60 minutes up to at least the length of a feature film. In this paper one main component of the data rate reduction procedure is described. A variable length coding and decoding chip, based on a 0.8 mu m CMOS gate array.
