JET AIRCRAFT technician peers

Ainto the bowels of a malfunctioning engine searching for the source of the problem.

5 Finally, he spots it. Buried deep within the engine is the troublesome part. He will have to replace it. A complicated procedure, to say the least.

10 The technician goes to his high-

powered workstation attached to a network and calls up the information on the part and the replacement procedure. An image

15 of the part seated in the engine appears. In another window, an instructor demonstrates the repair procedure in full-motion video while the technician listens through

20 the audio channel as the instructor explains the process. Diagrams pop up to further clarify key points. In a text window, he reviews lists of

necessary parts and tools he will

25 need to complete the repair.

Still confused about an irregularity in this situation, the technician presses the help key and a real-time image of a live

30 supervisor pops up in another window. Using the attached microphone, the technician discusses the particular problem with the supervisor, who directs

35 more information onto the technician's screen. The technician points a video camera at the part in question to show the supervisor the specific situation.

40 Welcome to the world of high-

end multimedia. The situation described above is not quite here yet, but most of the pieces already

exist to make this scenario

45 become a reality using a

networked RS/6000 or other high-powered workstation.

Or take this example of a

scenario that is more likely

50 today. A manager creates a detailed business presentation involving text, graphics, digitized photographic still images, and tables of spreadsheet data all

55 combined in a single compound document. Before sending the document across the network to a colleague, the manager picks up the microphone and attaches

60 an audio note to one of the tables, reminding the colleague about something unusual or potentially confusing in the accompanying figures.

65 Using a networked RS/6000

equipped with the necessary audio boards and Bolt Baranek & Newman's (Cambridge, Mass.) BBN/Slate, a compound

70 document/office automation application, this scenario is

possible today. High-end multimedia is only in its infancy, but it is here. And over the next

75 few years, industry observers expect multimedia development to accelerate as current barriers are overcome.

Multimedia is not a new

80 phenomenon, although it is new to business computing. We live in a multimedia world. At home, we experience a variety of media through our television: full-

85 motion video, still images,

graphics, sound, and animation. ►

⁴¹¹ At school, we learn through systematic exposure to different media: the instructor's words, text,

90 audio tapes, graphics, and a variety of visuals and video.

Computers, however, have tended to be uni-medium. Traditionally, computers were text-

95 based, and this continues to be the

primary format for business information. A few systems have provided sound or graphics, but until recently, the efforts were

100 rudimentary compared to the

seamlessly integrated, high-quality visuals, video and audio we experience every evening at home. ■
