Progressive Scanning: An EDTV Gateway to HDTV

Bernard Tichit, Gary Tonge, Jean Pierre Lacotte

This article describes joint experiments by Thomson Video Equipement and the U.K. Independent Broadcasting Authority (IBA) that have demonstrated some of the capabilities of an extended-definition television (EDTV) system using 625/50/1 (progressive) scanning at source and display and 625/50/2 (interlaced) scanning for intermediate studio processing and transmission. Also described is the first application of this EDTV system. A large outside-broadcast (OB) production van has been built by Thomson, using the principles defined by this experiment.
