The Audio Visual Connection from the International Business Machines Corporation allows companies to actualize computer presentations that accommodate text, sound, voice, cartoon and video images – and at almost low cost.
Apple Computer Inc.’s Macintosh, a graphics-based computer that set the standards for affluence of use, already has a arch alpha in this field, which goes by the ambiguous appellation multimedia. The Commodore Amiga, from Commodore Business Machines Inc., is additionally able-bodied ill-fitted to multimedia production. But I.B.M. PC’s and accordant models accept never been accepted for acceptable complete or graphics. Until now.
Multimedia is a boiler these days, although the abstraction is hardly new. Television, for example, is a multimedia device. Some analysts accept appropriate that computers and television are destined to merge, consistent in ”smart TV’s” or ”video computers.” Although the affiliation of full-motion video on a computer awning is still some time off, articles like the Audio Visual Connection represent an antecedent footfall in that direction.
The abstraction is simple: a computer-based sales presentation or training affairs that includes photographs, video, activated diagrams, a agreeable soundtrack, a announced narration, argument and abstracts fatigued from the user’s abstracts base, all put calm with adult techniques adopted from able acoustic productions. Its designers accept it will authority a viewer’s absorption abundant bigger than the ”slide shows” that are accepted on computers today.
But multimedia is not yet simple or inexpensive, and those it charge be to bolt on in accumulated offices.
I.B.M.’s Audio Video Connection is a $3,310 aggregate of software and two constituent boards that is advised to assignment on high-end PS/2 computers. One lath captures and processes audio signals, the added video. The boards fit into Micro Channel amplification slots, a blazon of aperture acclimated by I.B.M. and a few added claimed computer makers.
One appliance that uses Audio Video is an alternate adviser to the burghal of Austin, Tex., area I.B.M. developed the constituent boards. The arrangement mixes blush accurate and still-frame video images of Austin with a soundtrack, and links it to a abstracts abject absolute text, complete and images. Appliance a mouse, the user can baddest accommodation of absorption – parks, for example, or high-technology companies – and a glossy presentation begins.
Such presentations, after the computer involvement, are annihilation new. Cities, companies and government agencies commonly accomplish promotional videotapes.
But computer multimedia has advantages. While television or video band is passive, computer multimedia can be interactive. The eyewitness can ascendancy the adjustment of the presentation through keyboard or abrasion commands (or by affecting the awning in some cases), exploring the actual about instead of linearly, as with a video tape. Laser video disks are additionally interactive, but they are added difficult to produce.
Computer multimedia applications are, in general, beneath big-ticket to accomplish than video productions, already the start-up accessories and training costs are absorbed. ”In abbreviate time, I was able to put calm a five-and-a-half-minute presentation that would accept amount the applicant $5,000 to $10,000 if it had been produced on video,” said Mark C. Sherman, admiral of Audio Visual Computer Applications Inc. of Austin. ”Using A.V.C., it was $1,500,” he said, apropos to the Audio Video Connection. Able acoustic productions generally amount added than $1,000 a minute, because they are acutely activity intensive, he said.
But the almost low amount of Audio Video may be misleading, Mr. Sherman cautioned. To aftermath his results, which analyze agreeably with those of a able acoustic studio, Mr. Sherman uses a able computer with high-resolution cartoon and a appropriate monitor, a agenda video camera, audio and video cassette decks, a accelerate digitizer, a flat video adviser and added equipment. That agency he is demography advantage of Audio Video appliance accouterments that amount added than $30,000. It ability be a adamantine advertise to actuate accumulated acoustic departments to accomplish that affectionate of investment.
Another abeyant hurdle is that Audio Video appears to be complex, akin its account to companies area at atomic some advisers accept a acceptable compassionate of both acoustic assembly and computers. As a result, the Audio Video Connection may acquisition its greatest use amid acoustic professionals and companies that advance multimedia applications.
One such aggregation is Creative Services Inc., of McLean, Va., which uses Audio Video to aftermath multimedia applications for audience including Disney World and the Pentagon. The aggregation additionally has ”a arrangement with Caterpillar to advance accomplishment training applications,” said Judith A. Mezzullo, carnality admiral of marketing, who said she expects training to be the best cogent appliance for Audio Video in the abutting decade. ”Data can be afflicted rapidly and modifications to accomplishment accessories can be adapted quickly,” she said. ”With a video disk, you accept to actualize a new deejay and accept it manufactured, mailed out and installed.” Audio Video can be adapted on a computer network, she said, adding, ”Where abstracts is alteration and you charge the best accepted data, this is bigger than video disks.”
Creative Services is additionally developing a multimedia arrangement adaptation of the assorted advertisement account acclimated by realtors. Such a arrangement would accredit audience to sit at a computer with a bounded absolute acreage agent, ample out a contour of their apartment requirements (four bedrooms, four baths, fireplace, copse and so on) and affairs (in the $200,000 range, with $50,000 bottomward and abstraction their choices in added cities. Within minutes, the arrangement would appearance them exterior, autogenous and adjacency angle of conceivably a dozen houses that appear abutting to affair their descriptions. The affairs could additionally analysis bounded mortgage and tax ante and appearance the audience graphically what it would cost, including closing costs and account payments, to move into anniversary house.
Such an appliance would crave far added abstracts accommodation than is accessible on best computer networks today. But long-distance carriers and bounded blast companies are planning to install fiber-optic agenda buzz networks in the mid-1990’s that accept far beyond accommodation and may be able to handle such applications.
Another important advantage of multimedia is that because the advice in the presentation was created by and fatigued from a computer, it can be afflicted or adapted in beneath time, and at beneath expense, than with video, which would accept to be refilmed, edited, bogus and mailed.
Neither I.B.M.’s Model 70, with its bound amplification slots, nor the Model 80, with its almost apathetic microprocessor, is an ideal Audio Visual Connection machine. Until I.B.M. comes up with a bigger computer, the best apparatus to run the Audio Visual Connection would assume to be a bigger, faster Micro Channel machine, like the Advanced Logic Research Microflex 3300, which is powered by a 33-megahertz Intel 80386 processor.
