Paper 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. This paper describes the hardware realization of the data rate reduction codec. Algorithms utilized for data rate reduction are adaptive intraframe/intrafield discrete cosine transform (DCT), adaptive quantization and variable length encoding (VLC). Interframe editing, multiple copy and shuttle mode are supported by a special codec architecture.
