Filtering, scanning and coding of HDTV-signals

A coding procedure is described by means of which the data rate of a HDTV-line interlace signal of about 1 Gbit/s can be reduced to less than 140 Mbit/s without visionally perceptible impairment of the picture quality and transmitted via a broadband digital channel of the future B-ISDN. Thereby the picture is dissected in a motion-controlled manner and subscanned three-dimensionally.
