" A Farewell to PAL" The analogue colour TV system
Talk by Roger Dealtry (He Him)
This is a talk on the PAL (System I) colour television standard. Something that was once used in every home in the UK, but now with the advent of digital broadcasting has quietly slipped into the pages of history. It deserves one final fanfare and who better to give it some love than the EMF community. We're going to marvel at the sheer engineering ingenuity of the PAL system at a fairly technical level, the remarkable way it makes use of aspects of the video signal spectrum, psychovisual phenomena and the prevailing analogue technology to cram a quart of functionality into a pint pot of spectrum. We see the engineering wisdom of considering a system holistically. We'll also look at the factors leading to its development, the way it addressed the shortcomings of earlier systems, and put PAL in its historical context with the existing black and white service, NTSC, SECAM and its eventual use in direct to home satellite broadcasting,
