lie service of stupendous proportions,
medium with new engineering tech
niqueS, new program ideas, new tai
ent and new commercial application :"
Here are a few of the things
which must be kept in mind The
structural strength of the iconoscope,
or eye" of the television transmitter,
and the lens system of the camera
are two determinants of studio length.
Studios must be high enough to raise
the lighting equipment clear of the
lconoscope'S range and yet permit
clear view of the entire set by engi-
neers and production men in the
elevated control booth N. B. C.'s
Radio City experimental studio is so
feet long, 80 feet wide and l8 feet
nigh. 1t accommodates one large
scene and an additional smaller one,
permitting shifts without restaging
Mr.. Hansen again: The micro
phone technique employed in televi-
sion differs from that in radio mainly
with regard to the respective loca-
tlons Of the microphone and the per-
formers. In radio. the performers
may change their location to suit the
one chosen for the microphone, while
in televlsion, the microphone must be
moved to the location of the per-
former. 1t is desirable further to
correlate the acoustical pickup with
the visual. That is, Closeup"
should sound like Closeup and
distant shot" should sound distant.
A majority Of the pick-ups have been
made with the velocity microphone,
equipped with wind shield and sus-
pended from boom which traverses
the scene of action"
The lighting system, with total
power consumption of more than So
900 watts, has created a serious prob
lem in air conditioning Lighting
units, some suspended from the CELL
ing and others operated on the studio
floor, generate so much heat that
means have been sought to diffuse
heat radiation for the comfort of
performers and technicians. Heat
filters, placed in front of the various
units, have alleviated the problem, in
part. They are made of glass, cut
in strips to relieve strain within the
glass, caused by high temperatures.
Heat is absorbed without causing un-
due reduction in the amount Of light.
TeleviSion is destined to become a
stupendouS industry and, when it
finally is commercialized, the enter
tainment purveyed is almost certain
to be aWe-lnspiring, but trading in
that radio for television receiver has
no place on the must list of things
to do for several years at least, prob
ably closer to five.
