COST 206 was the first European project in the field of high-definition TV signals in Europe. The topics to be studied were motion adaptive pre- and post-filtering with various subsampling and re-interpolation strategies and source coding. The target bit-rates for digital transmission were 560 Mbit/s and 140 Mbit/s. Results from investigations into motion adaptive pre- and post-filtering led to the development of a wideband MAC system which was practically tested over the 90 MHz transponder of the German satellite KOPERNIKUS. The research in source coding resulted in a 648 Mbit/s HDTV codec based on DPCM techniques for multi-gigabit networks (RACE 1051) and in several sub-band codec proposals for 140 Mbit/s, one of which has been implemented and will be used for wideband satellite channels and the switchable German fibre optical network VBN. The advantages of progressive versus interlace and quincunx scanning with respect to coding gain were also investigated.
