FAR THOSEIN KNOW Intricate Machinery, Cost Of Installation And Prob lem Of Finding Programs And Customers Obstacles By Slilncv B. Whipple United Press Staff Correspondent (Copyright, 1935. by United Press) NEW YORK (UP) Sound broad casting, the system that brings you the tones of symphony orchestras and publtc speakers. Is simple compared to the intricacies and complexities of television. Even those who know the most about it. men such as Dr. Alfred Norton Goldsmith or Charles Horn, hesitate to describe the process to a layman. Briefly, however, the system Is this. At the transmitting station a scene Is scanned by an electric "eye." which translates the lights and shadows of the "picture" into electronic waves and shoots them Into the ether. The eye travels at unbelievable speed from the left to the rlpht of the picture, one "line" at a time, and at the com pletion of one line, drops down a fraction of an Inch, to the next line. When it has completed one picture, it returns and does the Job all over again. And this, If you please. In a fraction of a second. At the receiving end, there must be a machine to turn the electrical Impulses back Into light. This Is done by a process too technical for description here, by "cathode tubes." MrchaitJral Urn Mi A strong light, operating In the re verse of the original system by which the scene was picked up. Is used "like a paint brush," and "paints" the pic ture. In black and white, all over again on your screen. The screen la coated with oxides and other metals which become bril liant when bombarded with the stream of electrons that pour from this "electronic machine gun." "And when I say a bombardment, I mean just that," said Dr. Goldsmith enthusiastically. "These tiny projec tiles bang against the screen at a velocity of thousands of miles a sec ond. As they strike the screen they Illuminate It. from left to right and up and down, with the . same high lights and shadows of the original scene, but so rapidly that the eye Is completely fooled and sees the pic ture as a whole." Problems Sttll Left That sounds simple, and the pro cess actually Is accomplished In 1 a bora t ory work . B ut t h ere a re a thousand unanswered problems that must be solved before the process can be made commercially t thinkable. Some of the problems are In radio engineering. Some of them are pure ly psychological. Many of them are actually economic, for television, to meet the same standards and enter tain the same number of people who now enjoy radio, would require bil lions not millions, but billions of dollars. A coaxial cable, an Inch or so In diameter, must be built for transmit ting pictures across the country, in order to provide the 1,500.000-cycle band required, and such a cable Is now only in the process of experimen tal construction. Or. alternately, hundreds of repeating stations must be made to dot the country at 35- mile Intervals. Both are costly. j The first receiving sets will neces sarily be expensive, how expensive the radio engineers hesitate to say. But they are actually five receivers In one. One receiver Is for sound, another for the picture, a third for "line reflec tion" (which swings your electronic machlnegun or paint brush back and forth over the screen), a fourth for "vertical deflection." (which swings the paint brush downward from line to line), and a fifth for "background control," wblch takes care of regulat ing the dark greys, the light greys, the high lights and the shadows of your picture. Big Investment Let us suppose, for Instance, that thCBe first sets, two, three or four years hence, will cost 6500 apiece. Ten million of them would mean that the public would hae to dig up (5. 000.000.000 to buy them. "And that, together with the mil lions that would have to be put Into construction of the sending appara tus." said Dr. oldsmlth. "would be a major economic operation that would stagger even Washington I" The sets would have to be serviced by a newly trained army or radio ex perts, who would be "engineers" rath er than repair men. The layman couldn't throw a wire out of his win dow and proceed to pick up televis ion. Nor could he fumble around with the insldes of a machine carrying a tremendously high voltage. The ma chines will be safe, of course, and fool proof. But the handy-man-around-the-house won't be able to fix them If they go wrong. $30 Tubes Tubes will cost as high as 950 apiece, and that Is no Inconsiderable sum when the possibility of seeing the whole system Junked in a year is brought to mind. Then there are other perplexing questions. Where wljl the material hjbjb Vim a OA Cffc fiii EAST MAIN ST. PHONE 429 The Home of FINE WINES H V. V.

Hollywood today spends $1,500,000. 000 annually to put out 500 hours of entertainment one-tenth of the ma terial necessary If television is to be come half as successful as radio. There will have to be a new tech nique In television writing and acting. There will have to be new stages and new stage-lighting engineering. There will have to be new costume tech nique. "And if the attitude of the aver age 'looker' is that of the average radio listener, the engineers say, the criticism of programs will be terrif ic." Program Perplexities What kind of programs, then, will be offered? Will the public be able to concentrate Its attention and fo cus its eyes on the screen for any considerable period of time? When you look at a television picture, you won't be able to play bridge, as you do when tho sound-radio Is going. In the first place, the room will be in semi-darkness. In the second place, the ear. which Is not directional, can pick up sounds even if you're In the kitchen mixing a highball. The eye I can t pick up anything at which It is not directly focused. There's a big Job ahead for every- notiy, inereioro, and that Includes rndlo engineers, electronic experts, psychologists, and craftsmen In the field of public entertainment. By 1937 or 1938 perhaps!
