You won’t believe the paint job on these 1947 French cameras! The build is pretty interesting too! Notice that the viewfinder is built into the pedestal column. Thanks to Brock Whaley in Ireland for sending this.
Friday, September 7th, 2022 was the 95th anniversary of the invention of electronic television. In 1927, 21 year old Philo T. Farnsworth and his 18 year old bride, Pem, demonstrated their invention to two Crocker Bank investors in the second floor lab of a rented garage at 202 Green Street in San Francisco. That day, […]
Answer To An Interesting Question… A while back, someone asked me how the signals from NBC’s many studios around NYC got back to 30 Rockefeller Plaza. Microwave or coaxial cable? Turns out it was usually coaxial cable. The one exception was NBC’s Uptown Studio at 106th Street. Most of the other theaters, like the Hudson […]
The Original GE Color Prototype Camera This looks a lot like the early RCA color prototypes, but it came later and was crafted from photos and demonstration broadcasts the GE engineers had seen. Although RCA was leading the way in Dot Sequential color, GE began to edge into the color field after the FCC chose […]
THIS IS A HUGE DISCOVERY!!! Over the years, I have seen the occasional reference to Saturday rehearsals of ‘The Ed Sullivan Show’ and have wondered if that was correct and here’s why…Jackie Gleason. Since signing with CBS in 1952, his live shows always came from Studio 50 and always aired on Saturday nights. Only after […]
definitely the strangest cameras I’ve ever seen!
France decided to go with 819 lines a year later.
Exactly Brock. 819 lines at a rate of 25 fps. ( 220 volts 50 hertz )
Work on SECAM began in 1956. The technology was ready by the end of the fifties, but this was too soon for a wide introduction. Initially, a version of SECAM for the French 819-line television standard was devised and tested, but not introduced. Following a pan-European agreement to introduce color TV only in 625 lines, France had to start the conversion by switching over to a 625-line television standard, which happened at the beginning of the 1960s with the introduction of a second network.
Obviously, not an RCA turnkey operation.
The 819 line channels took up 14 MHz of bandwidth. And that with AM sound. Their VHF channels were not adjacent, but overlapped in frequency. 14 MHz of I.F. bandwidth made a home receiver very expensive. Six or seven stages of I.F. amps were not uncommon. The audio from the former French channel 2 (41-55 MHz) was often heard by me in Florida during the sunspot maximum of the 1970’s, along with sound from 405 line BBC-1.
