Electric Camera, Improved Images

ering laboratory curiosity to a
process beginning to show definite
entertainment possibilities.
But generally, it is not yetready
for public introduction; neither is
there any indication when this
stage will be reached.
Included in recent advance
ments have been the development
of an electrical camera as flexible
as microphone, the use of a
greater number of lines per pic
ture and an increase in the num-
Der of frames, or pictures, per
second to provide motion picture
effect, both resulting in enhanced
detail.
Great Progress Reported
Such are the reactions obtained
in a discussion of the present
status of television with w. r. G.
Baker, vice president in charge of
manufacturing and engineering
for RCA Victor, and DIR. Vladimir
X. Zworykin, who has been re-
spensible for much of TIA develop
ment work in the laboratories here.
From the viewpoint of the re-
search engineer or physicist, great
progress has been made in the So
luton of the fundamental prob
lens Of television," Mr.. Baker
said, "but from the engineering
standpoint there is still plenty OF
work.
Two Serious Problems
There are two serious problems
that must reach a definite solution
before we can even begin to think
of. starting television. We must
determine the system to be used
in advance, for once we get into
television we cannot shift around.
If we make receiver capable of
operating on 240 lines, we must
stick to that within reasonable
limits.
Another thing is programs. If
we have 16 hours a day from
where all of the material will
come is something / can't answer.
Research Work Completed
"There have been two types of
definite advancement. First, the
research workers have completed,
at least for the present, their
work on certain of the basic tools
necessary and have turned them
over to the design and develop
ment engineers.
Second, the research engineers,
having completed tie first step in
their work, have been able to
turn their attention to the fur
Their improvement of the ideas
they have developed and also to
the study of new tools. By tools,
l mean all the apparatus used in
television.
THUS, you can see that u date
for the introduction of television
is something that can't be fore
cast yeti
But DIR. Zworykin, VINO has
done so much in the development
of the kinescope and the icono-
scope, both based on the cathode
ray tube, looks at the situation
with the eyes of the research man
who also has many problems. The
kinescope Is the receiving ele-
ment, while the iconoscope is the
transmitting tube that takes pic
lures of moving objects electric
ally.
AT present we are pretty well
satisfied that television will find
a place in the channels AROUND
five meters" DIR. Zworykin says,
where from 90 to 40 wave bands
should be available.
"0n these waves, the area COW
cred by a single transmitter.
when it is located on high build
ing like the Empire State in New
York City, is not greater than so
miles at this time. The limitation.
however. makes it possible to dup
licate stations 100 miles apart on
so on the same wave band with
out interference.
Received Image Green
While we are working on a
means Of projecting picture
from the kinescope upon a screen.
we can obtain an image six and
one-half by seven and one half
inches directly on the flat end Of
the larger tubes. This appears IN
a light shade Of green. We also
have inrreased the number al
frames per second from "a To IS.
enabling US to improve tho over.
