Progressive Scanning: An EDTV Gateway to HDTV
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.
