"Assuming that in 1953 or 1954, the TV and film images become interchangeable,
a very striking alteration of studio technique is possible.  There is no
technical reason why this development should be any longer delayed, since
the studio TV channels would not be bounded by the low-resolution limits
set by radio waveband restrictions.  Thousand-line channels could be designed
today, since amplification of 25 to 50 megacycle bandwidths is already
possible, and the signal would presumably be transmitted from camera to
floor by coaxial cable."
