But it wasn't. It was made by General Electric for a standard that differed from the one proposed by CBS. Read more here.

Ok, interesting! Have you some more informations about this set and this other field sequencial system? So the guy on the BBC film is not right?

Stated in the Technical pages, the V rate is 144 Hz and the H rate is 37,800 Hz.
this means the video produced an interlaced 525 line, 144 field image on the set. In today's parlance 525@72i.

For a single pure primary color (e.g., all green) it was 24i. Flicker on neutral colors would be reduced somewhat by the addition of the blue and red fields, but overall it would be similar to 24 fps movies with the usual double shuttering.
