Don't be intimidated

"There is nothing I love as much as a good fight." Franklin D. Roosevelt.

At the recent NAB Convention, the FOR.A company announced they were being sued for infringing patents originally held by Consolidated Video Systems (CVS). The suit was brought against FOR.A by Video Patents Limited, a.k.a. Video Process- ing Technology, a California -based corporation formed in the late 1980s by Carl Coop- er, a former CVS employee, and his business partner, attorney Daniel Leckrone. A press release from FOR.A acknowledged the suit, and stated that threats also may have been made against other video equipment manufacturers. Great, this is just what we need -a few people trying to shut down the entire video production industry by claiming infringement on patents, some of which have either expired or are within a year or so of expiring. Those I talked with noted that for the most part, the patents were never enforced, most likely because there was widespread industry knowledge of prior art. Don't misunderstand me. Patent infringement is wrong. But so is the frivolous attempt to reap unearned profits from those who push forward the edge of technology. The companies that research and then develop new products should be rewarded from the sales of those products. We don't need people who try to unfairly claim a piece of the pie when they may not have had anything to do with bak- ing it in the first place. In today's litigious business climate, everyone sues everyone. The result is that no one wins. And in this case, the equipment users lose. It's time to say no. I urge the companies being challenged to stand firm and protect their own rights and their customers' rights. Don't allow those who may be trying to profit through the buying of old and obsolete patents prevent you from bringing new products to market. Protect your company's future and integrity by standing your ground. In the long run, your company, the industry and your customers will be far better off - even if it takes a good fight to gain victory.

3 -D growth Although many stations own a 2 -D or paint system for bread -and -butter graphics, most are just beginning to bring 3 -D in- house. Several reasons have delayed the onset of 3 -D at the local level: Earlier 3 -D modeling, scripting and rendering software required operators to have a technical programming background. This often shut out production artists and art directors who were not computer literate. Most stations' art departments have only a few hours to create graphics for each evening's newscast. This is particularly the case if any late- breaking stories occur. Unfortunately, 3 -D rendering - the process in which the computer calculates the color, position and lighting of each pixel - formerly took days, not hours.

Even before Panasonic developed D -3, video producers had their own vision of what they wanted in a digital videotape system. They'd seen D -1, but most couldn't justify the expense of component digital video recording. They saw D -2, but recognized that its applications and production features were severely limited. So, many let D -2 go by. Though D -1 and D -2 were digital, they weren't their kind of digital. Now they've seen D -3, and they're using D -3.

D -3 has the price and performance requirements they need to finally replace Type C and move into the digital world. In fact, almost every D -2 user we've invited to try D -3 has wound up buying D -3. The Panasonic D -3 format has a one -piece camera/recorder, plus a field -portable recorder, studio recorder and M.A.R.C. Automated Cassette Library System. And, it needs just a fraction of the maintenance and adjustment required by analog and earlier digital formats. Now, isn't it time for you to share in the vision of digital -the way you want it?

L Square Hood for Optimal Results - A square hood, that has more cut at the upper and lower edges, has been added to the lens. The square shade matches the aspect ratio and offers better protection from stray light, inclement weather, dust and the effects of the environment. It also reduces ghosts and flares.

Flexible Use of Filters - Because filters can be stationary at the front during focusing, the system allows better use of special effect filters like cross, snowcross, polarizer, multi - vision and half neutral density. Re- indexing is now a thing of the past.

Li Compactness and Ease of Use - The weight of the accessory does not affect the actual movement of the J 14ax8.5B IRS front element and does not harm the focusing operation. Response time is greatly improved.

www.americanradiohistory.com 4iiit If you've ever dealt with a 2" 24 -track whose synchronization was a design afterthought, you'll appreciate the speed and pinpoint accuracy of the TASCAM ATR -80. fts microprocessor-controlled transport is specifically designed for the repeatable locating you need for no- excuses, extra -fast lockup in synchronized operation. And the punch in/out precision you demand. Built with legendary TASCAM reliability, the ATR -80 will continue to get the job done -session after session, project after project. It is also plug compatible with Dolby SR racks. Available in a higher capacity 32 -track format. And, of course, accommodates 14" reels. But, you be the judge. To arrange for a personal demonstration of the rapid-response ATR -80, just call (213) 726-0303. Or write TASCAM, 7733 Telegraph Road, Montebello, CA 90640.

www.americanradiohistory.com BEE '92 dcast Equipment Exhibition

November 11 -13, 1992 Nippon Convention Center (Makuhari Messe)

BEE SURE TO ATTEND! Inter BEE is the place to be. It's the one forum that gathers the world's most dramatic developments in broadcast, video and professional audio technology. Industry participants agree: last year saw 27,000 visitors and 390 exhibitors from 20 countries ex- hibiting their newest technologies in 1900 booths.

The impact of technological ad- vancements is creating new opportunities, not only for hardware providers but also for operators who are looking at ways to develop new markets for news and entertainment media. So, in addition to exhibits of the latest video, broadcast and audio equipment, fo- rums, seminars and symposiums on the state of the art run concurrent with Inter BEE '92 over the three days of the exhibition.

Building on the dynamics of previous shows, Inter BEE '92 remains the Asian forum for industry leaders where ideas on the nature of the medium are debated alongside the very technologies that are helping realize the vision of a global community.

You can control all this with the "electronic tweaker "or the small remote control box. Because digital circuitry is constantly comparing and adjusting the camera's performance to the settings you established in memory, you can leave your vectorscope, tweaker tool and screwdriver home too. Drift is virtually a thing of the past. Digital circuitry gives you enhancement for chroma, dark, high and low band details; cross color suppression, highlight aperture, automatic shading correction, and much more. Digital camera technology like this should be available to everybody, so Panasonic priced the WV -F700 at just $10,000*, and designed it to dock with MII, S -VHS and Betacam SP VTRs without need of special adaptors. Even at this price, the camera's 750 -line resolution, super high sensitivity 2/3 -inch 3 -CCD image system (f8.0 at 2000 lux), and 62 dB signal -to -noise ratio are coupled with features like SMPTE color bars in the EVF, with time, date and camera ID. When it's time to choose your next camera, consider Panasonic's all- digital processing WV -F700. It's a decision that will require very little additional support.

New systems provide new opportunities.

s the digital revolution continues, new broadcast equipment has begun to reach an unprecedented level of maturity. Where- as earlier systems were directed at increasing the speed /capacity or otherwise lowering the cost of production, more recent devices have emphasized creative advantages. This is a subtle, yet welcome, change. It may assuage the oft -cited fear that broadcasting is becoming an increasingly robotic exercise. It also begins to close the circle of transition that broadcasting has traversed in moving from the analog to the digital age. As with any new development, a flexing of pure The Bottom Line technical abilities to their extremes comes first, followed by the development of a sensible aesthetic for the system's use.

It all adds up The role of new technology should therefore be considered in a broader context than how much paper, time and staff it can save at the broadcast facility. Some innovations can truly improve the broadcaster's product in a direct way, thereby providing the potential for demonstrable audience increase. On the other hand, even the systems that simply reduce a facility's operating costs can also provide a benefit in this regard. Money saved in administrative expenses can be applied to new program acquisition, for example, and help increase audience in an indirect fashion. What follows is a look at just two of the many possibilities available today. These approaches can provide immediate improvement to program quality in a technical and an aesthetic sense. The synergy resulting from these and other systems' enhancements supplies the perfect context for improving a broadcaster's position in the increasingly competitive marketplace.
