Re: Was 819 HDTV?
The 819 line system in the 1950's was poor when compared with the British 405 line system. Our pictures were sharper and the French sets that I remember when on a school trip to France in 1960, appeared to have less contrast. I doubt if the scanning spot could be made small enough to exploit the system to the full with the tubes available at that time.
The 21" tube was very popular in France I believe but I doubt if the end result was much better than a 405 line set with 'spot wobble'. If the system had been retained, no doubt with modern equipment the results would probably have been outstanding. Regards John.
