TELEWS|ON CENTER
Of RADIO EXHIBIT.
Opening of Fair Marked by
Discussion of When Public
May Expect Sets.
BY MARTIN CODEL.

NEW YORK, September 17.-Much
ballyhoo about television marks the
opening of the Radio Worlds Fair here
In Madison Square Garden. 1t is the
most discussed subject in radio circles
and the one occasioning most disagree
ment among persons in position 10
know
None but a few overoptinistic gentle
men will say that the simultaneous
transmission of moving images by radio
is perfectly accomplished fact. Wnere
various authorities disagree is IN their
predictions regarding when the pubic
NAV expect reliable televislon receiving
sets on the market.
Bona-fide experimenters with tele-
vision will be explaining their apparatus
and methods during the show here
this week. They range from extreme
conservatives to those who sincerely pe-
lieve that sets for the reception OF
action images will be perfected and
offered by this time next year.
Radios foremost authorities, eSpe-
cially those who have actually been do
ing research into radio vision, have
repeatedly cautioned the public not to
expect too much too soon from tele-
vision.
Front-page descriptions of the latest
DEVELOPMENTS in the art of seeing by
radio have led to a current conviction
that all that remains to be done Is to
put the televiSor, as the device will
probably come to be known, into pro-
duction. Nothing could be further from
the actual state of things.
Produce One-Act Play.
Moving images in silhouette can be

dividuals have been broadcast and
quite clearly delineated in tiny aper-
lures on highly complicated reccivers.
Two figures fencing and boxing have
been brought within focus and repro
duced Most recently, voices and
images synchroniZed to produce one
act play have been demonstrated.
But all this was done in the labora-
tory. The technical men, each time
they have demonstrated something new,
have made it clear that they have
advanced merely one stage.
The most insiStent caution against
the immediate expectation OF market
able television apparatus has come
from scientists and experimenters.
Visual devices being sold today are
mostly designed for use by amateurs
and informed technical men, who are
making valuable reports on reception
results to the broadcasting laboratories.
Many amateurs throughout the coun-
try are being employed by c. Francis
jenkins, the Washington inventor, in
his experiments with what he prefers
TO call ''radio-vision." They are, IN
his words, the pioneers" of new art.
M Jenkins is one of the best known
and most highly respected men in this
field He furnishes data gratis on the
building of experimental sets for the
reception of visual moving images
broadcast from his laboratory in Wash
ington.
u, Is Far Away.
A number anticipate that the first
successful home adaptation of tele-
vision will be a set for the reception
Of motion pictures transmitted from
strips of film, since light can be con-
centrated upon films most intensely.
Sound movies may be concomitant
stage for audio reproduction sinful
taneously with the visual will be
relatively simple matter. The time for
receiving actual scenes from theater
or a base ball game is perhaps further
away.
Still picture transmission by radio is
well developed. TeleviSion, however, is
in an inceptive stage. 1t is in about
the same state as the automobile of Is
years ago. One authority declares that
it is at the same stage of development
as radio-telephony before the begin
ming of radio broadcasting. The latter
took only a few years to jump into its
present high degree of perfection and
use; some think that television will
develop even faster, since the basic
principles of photoradio are well
understood.
Figures more clearly delineated and
magnified to larger proportions than
at present possible, confinement Of the
signals to narrower bands of fire.
Quencies and the construction of
simple and foolproof receiver, are a
few of the present lacks in the field
of television. Certainly no televisor
will be marketed on substantial scale
until it is at least as trustworthy and
foolproof as the radio receiving set of
O nalf dozen years ago.
There was struggle before the tele-
vision people obtained admission to the
exhibition floor for the Radio Worlds
Fair The Radio Manufacturers As
ISOLATION at first opposed their appear
ance on the scene That organization
has constantly been hammering away
at the proposition that television hopes
should not deter the public from radio
buying for fear of immediate obso-
lescence of receiving sets. Such is the
view generally held in the radio in
duStry.
