University makes big video and data impressions.

When the University of Michigan's Center for Performing Arts and Technology decided to purchase a large-screen video projector, Mike Knight, video technology consultant for the center, knew it would have to be versatile enough to handle a variety of applications, screen sizes and throw distances. This flexibility was essential to accommodate such disparate uses as course instruction, concerts, sports and special events. * Chosen One

Knight says he and the center's director, David Gregory, made the decision to invest in the GE Talaria LV8000 MP data/video projector. "We looked at some cathode ray tube (CRT) projectors," Knight says, "but their images weren't big enough or bright enough." The university had rented Talaria projectors in the past, and he and Gregory agreed the Talaria MP projector was just what they needed.

The university has since used the projector in and around Ann Arbor, Mich., for presentations to groups ranging from 100 to 2,000 people in both front- and rear-projection configurations. Utilizing a series of interchangeable lenses, the MP is capable of projecting picture sizes from 6'to 30'wide and can be positioned up to 200'from the screen for large auditorium applications.

The MP, which stands for multiple personality, is designed to hold up to 16 different "personalities" (computer and video formats) in its memory. Plus, it can interface with virtually any computer operating between 15 and 36 KHz. "We've used it with NTSC and computer graphics," Knight says, adding that the projector has been interfaced with Macintosh 11 computers and IBM systems running VGA or EGA graphics. * Video Dance

The Performing Arts Center, part of the university's School of Music, uses the projector in its music and dance courses. Knight says it adds a whole new dimension. The center teaches courses in video dance, music technology and more in an ongoing effort to combine technology and the arts. "We try to integrate music and the arts with electronic instruments, video equipment and computers," Knight explains.

All of the video dance programs, as well as other shows, are presented in the Power Center, a large auditoirium on campus that can accommodate up to 1,400 people. The Talaria MP displays a variety of colorful video and computer-graphic images on a 23'wide screen positioned behind the dancers on the stage. The result, according to Knight, is a spectacular multimedia performance.

Because of the presence of the dancers, the stage lighting in the Power Center must be kept relatively high. But this does not present a problem for the MP. "The stage is fairly well-lit-with a range from about 50 to I 10 foot candles," Knight says. "But we shoot from the rear with the projector, and it works very well." The MP uses a xenon arc lamp-powered light valve that produces extraordinarily bright images. N Sharing its Wealth

The center also leases the MP projector out for other on-campus purposes. One occasion, for example, was at the Towsley Center for Continuing Medical Education, located at the University of Michigan's Medical Center. A large group of cardiologists gathered there to view a series of live cardiac catheterizations projected on a 10' x 14' screen. What they saw were some of the latest techniques in coronary intervention performed inside cardiac arteries. By using the Talaria MP projector every movement was easily visible in clear, realistic color. And the projector allows for relatively high ambient-light levels, making it easy for audience members to take notes. N Provides Special Treats

Fun applications are not overlooked either. Soon after the University of Michigan Wolverines won the 1989 NCAA basketball championship, the team held a fund-raising event at Chrysler Arena. With the players and coaches in attendance, the function attracted a large crowd. And everyone was treated to videotaped season highlights shown by the Talaria MP projector.

In addition, the projector was also used at The 16mm Film and Video Festival held in Ann Arbor.

"It's a good size, easily transportable," says Knight of the Talaria MP projector. "I was confident it would work well for us."
