The Work of the E.B.U. Ad-Hoc Group on Colour Television: Reprint
The E.B.U. Ad-hoc Group on Colour Television was formed towards the end of 1962, with terms of reference requiring it to undertake an objective comparison of the several systems of color television and to make proposals for the discussions of a unique standard for color television in Europe. — After a preliminary examination, the Ad-hoc Group took three systems into consideration, namely the NTSC, SECAM and PAL systems. The functional principles that these three systems have in common, and also the different manners in which the color signals are processed at the transmitting and receiving ends, are described in this article. All three systems give satisfactory results under correct conditions, differences mostly became apparent only with critical pictures and abnormal transmission conditions, therefore very detailed comparison trials are at present being undertaken. As the task of the Ad-hoc Group has not yet been finished, it is still too early to publish any conclusions.
