When I joined the BBC in 1963, I asked how the pictures on the colour monitors were done and was told that they were matted in!<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"simon-vaughan-a7ab7575-dab2-44e5-b76f-774b0f60db14\">Simon Vaughan<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  Sylvia Peters had many a story to tell about the late-night colour test from Studio A at AP.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The attached video is of the first live studio colour transmissions (on closed-circuit) on 3rd April 1956:<a id=\"post-20136-Dave_Buckley\"><\/a><\/p>\n\n\n\n&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a name=\"_videoupload3\" href=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2025\/11\/Colour-Television-first-time-from-AP-3-4-1956.mp4\"><img loading=\"lazy\" decoding=\"async\" width=\"231\" height=\"37\" src=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2024\/02\/play_video.png\" alt=\"play video\" class=\"wp-image-11862\" style=\"width:auto;height:25px\"\/><\/a>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>[ed: this video is in black and white (film recording)]<\/em><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To return to this page, please click the &#8220;back&#8221; arrow in your browser.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<br><br>\n<h1>&nbsp;<\/h1>\n\n<br><br>\n<p class=\"western\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter size-medium wp-image-1061\" src=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall-300x104.jpg\" alt=\"ianfootersmall\" width=\"300\" height=\"104\" srcset=\"http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall-300x104.jpg 300w, http:\/\/tech-ops.co.uk\/next\/wp-content\/uploads\/2012\/07\/ianfootersmall.jpg 348w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n\n<br><br>\n<!-- END Footer -->\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Rob Miles In case you missed the item on R4 this morning, the attached item may be of interest.
