was the case in the S-3. There are only two actual operating adjustments, picture contrast and sound volume, although other controls for picture centering, size, focus, synchronization, linearity, etc., as well as input switching and monitor switching are provided. The equipment, which consists of three units, the projector, the control racks and the power supply, requires a space of approximately 14 square feet, and operates from a normal 120-volt, 60 cycle ac supply.

Essential Measurements

The long throw PT-lOOA equipment should be placed about 125 feet from the screen. At this distance it will give a very clear outdoor picture of 27 by 36 feet. The Rutherford drive-in used the equipment at a slightly greater distance.

Location of Equipment

The power supply should be placed in the generator room of the projection booth. The control racks should be placed in the projection booth. There are three possibilities for locating the projector.

(1) Construct a simple housing large enough to contain the projector unit, placing it on a permanent suitable base.

(2) Attach a steel collar and a connecting straight steel beam to the projector unit. The steel beam should be approximately 12 feet long. Imbed two steel members, placed several feet apart, in about four cubic yards of concrete. The distance from the bottom of the concrete to the ground surface should be approximately six feet. Drill holes in each of the steel members above the ground large enough to accommodate the rugged bolts. The purpose of this construction is to permit the steel beam attached to the projector barrel to be lowered between the two steel members imbedded in the ground and the steel member attached to the projector unit.

(3) In special situations the best solution may be to place the projection equipment in a trailer and project out of the back of the trailer. Whatever arrangement used, it is important to protect sight lines. The junction box for the television equipment should be placed near the projector barrel.

Layout of Drive-In

On the basis of the experience at the 3-3, the front ramps should be left open for temporary seats, also a portion immediately in front of the screen, as far as the screen may be visible. The in-car speakers can serve nicely to radiate enough energy to afford adequate hearing for the seated group. However, to accommodate the people immediately in front of the screen, and to augment the sound for seated persons, the audio of the television event should be placed through the (lrivo-inls regular loud< speaker system, plus one other standard speaker located at the top center of the screen.

Telephone Facilities

The event may be brought to the drive-in theatre by means of either microwave or coaxial cable. Quality of picture obtainable by either is virtually the same. Telephone facilities should


lead to the projection booth and then be dispersed to the TV projector housing. special events."


On the basis of what happened at the 8-3 Drive-In, and the reports that many other drive-in operators have shown a live interest in the subject, it is possible to make a number of guesses as to what will happen in the near future.

It is common knowledge that for the past few years the most active branch of theatre exhibition has been the drivein. It has seen a tremendous growth in a short span of time, and is still in the process of expanding, With the casing of the material situation a staggering number of outdoor theatres should be in operation by the end of this year. This not only indicates a high degree of Showmanship on the part of the drive-in operators, but also is positive proof that this is the type of theatre that appeals to a large segment of the movie-going public. Therefore, it seems reasonable to assume that drive-ins can offer a large enough audience group to be able to buy up top events in the world of sports and entertainment. As more and more outdoor and conventional theatres equip themselves for television, they can present a fight promoter, for example, with a guarantee of a gate that would run well into the millions of dollars. It is not completely out of order to suppose the some time in the future drive-ins will be able to arrange for programs especially designed for outdoor audiences, and use them to round out their regular programs, in the place of a second feature.

As better techniques and equipment are developed the quality of outdoor television productions will improve. Eventually screens especially designed for filmed and TV presentations will probably evolve. Although the instantaneous system was used in the 8-3, this by no means indicates that the intermediary system has no place. The fact that the latter makes use of film might indicate that it will give equally good, or even better, results, since it can make use of the driveeins regular projection equip ment, which is geared to the requirements of outdoor theatres as regards to lighting, sound, picture size, etc. This is a question that has not been answered by any means.


As of this moment no one can say just how far outdoor theatre television will go, and how much of a part it will play in the future of driveuin operation. However, every indication seems to point to its taking an important place in the scheme of things. One thing has already been proven. That is that the film industry still has the courage and inclination to try something new. The management of the 8-3 Drive-In were willing to take a chance that could have cost them quite a sum of money. Naturally, they waited until they had a strong attraction, but many things that have been "sure fire" in discussions and on paper, have fallen fiat when put into practice. The RCA engineering staff was faced with a challenge both to their equipment and their ingenuity. The huge success of the experiment is a tribute to their ability.

The first step has been taken. Once more the industry has demonstrated its ability to modify and turn to its advantage something which appeared to be capable of doing it great harm. Theatre television is still in the formative stage. It is faced with such problems as obtaining channel allocations, of solving the time delay situation that often makes it impractical to carry a program on a nation-wide basis. It is faced with the problem of getting materials, and having enough theatres equipped with theatre TV. There are many, many such hurdles which must be leaped before it can reach its full potential. However, there is every likelihood that when theatre television does reach its peak, driveins will be playing a major role.

It can hardly be denied that the drivein is a hardy and robust young branch of motion picture exhibition. And like a youngster, it has the strength and stamina to take full advantage of the new and modern things that come.
