`
` Prestel is viewdata. The British based
`
`electronic information utility now
`as Prestel was originally named
`Viewdata
`(with
`a capital V). But
`-'ttierata quickly became a generic term
`used to refer to any interactive videotex
`service, and the premier viewdata service
`was renamed Prestel.
`Prestel is run by the British post of-
`fice, known as British Telecom. which
`also runs the telephone system in the
`UK. Over 900 organizations contribute
`information to the 230,000opage Preste]
`database. Subscribing to Prestel
`is like

`I even sent an eiectronic greeting card
`to Prince Charles and Princess Diana
`congratulating them on the birth of their
`son. I received a reply. too. Through sev-
`eral newsletters published on Prestel
`I
`keep track of new developments in the
`videotex industry. Since I am planning a
`trip to Australia, I used the Prestel ad-
`vertiser reply service to request
`travel
`brochures. The Australian Tourist
`Commission sent me a packet an inch
`
`thick. There is such a wide range of
`information on Prestel. you might find it
`hard to think of a topic about which
`some information provider has not put
`up pages. Looking for a ferret? You can
`find information about
`these unusual
`pets on Prestei.
`I have been a Preste] subscriber for
`over six months now, but I am still Stir--
`prised at
`the volume and variety of
`information available. That's the excite-
`ment. Nearly every time I sign on, 1 dis-
`cover a gem of information I did not
`expect. And some of the information
`would be hard to obtain elsewhere.

`Menu Driven Access Structure
`The model for Prestel information

`trieval is print. It is a library of regu ‘-
`updated periodical information. Inde .31

`ing of menu choices allows Prestel to i.‘
`accessed with a simple numeric key'
`This speeds up menu selection and :’
`lows one to sit back in an easy chair ‘ :i'
`a keypad smaller than most TV rem_
`controls.
`If menus seem like a slow way to =-
`trieve information, remember th
`Prestel is designed to be received at 1
`bits per second (bps) and that an a
`tremer efficient operating system
`sures a consistent reSponse time of 1

`
`information utilities like The Source and
`Compuserve, Prestel differs markedly
`from these services in display format.
`indexing structure, and database
`content.
`
`Standardized Page Display
`All information on Prestel is designed
`to be read in pages. or screens, cOnsisting
`of 24 lines of 40 characters. Both upper-
`and lowercase alphanumeric characters
`are supported, as well as two special
`graphics sets of 64 characters each. All
`characters can be displayed in any one of
`seven colors against any one of seven
`background colors. and can also be dis-
`played in double height or
`flashing
`mode.
`To use Prestel, you must purchase a
`special terminal that supports the dis-
`play protocols, or buy hardware or soft-
`ware products
`to adapt
`a personal
`computer to Prestel. Currently, the Ap-
`ple II and TRS—SO Model III can be
`adapted for black and white display sim-
`ply by running special software.
`Combination software/hardware pack-
`ages exist for color adaptation of Apple
`II,
`IBM,
`and
`S-lOO bus personal
`computers.
`Use of a standard diSplay means that
`there are never awkward line wrap-
`‘around problems, and important
`information never scrolls oil“ the t0p of
`the screen. All information on Prestel is
`transmitted as one or more complete
`pages that are written on the screen from
`top to bottorn.
`Although color may not Seem im-
`portant for textual
`information, many
`Prestel information providers make ex-
`cellent use of contrasting colors
`for
`emphasis or to lead the eye. And the
`combination of color, lowercase charac-
`ters, interesting page layouts, and graph-
`ics makes Prestel a true communications
`medium, not simply a database.

`
`As a former advertising agency cre-
`ative director. I may be especially sen-
`sitive to the visual design capabilities of
`Prestel, but when I give demonstrations
`of both The Source and Prestel to my
`
`university classes, the students
`
`Many Prestel
`information providers
`make excellent use of
`
`contrasting colors for
`emphasis.
`
`
`
`overwhelmingly favor the visually more
`exciting Prestel display. To a generation
`brought up on mass media and video
`games, it is not enough that computers

`as a new arcade fad, a slick publication,

`Users with full alphanumeric keybo u:
`can also send electronic mail

`this benefit should not be underrated.
`
`A Publisher’s Clearinghouse
`An information service is no bette'
`than the information it provides. The ul-
`timate benefit of Prestel is its range an
`quantity of information. This is the re
`sult ofa two-tiered information provider
`([1?) structure that makes it attractive
`for publishers both large and small to
`use Prestel. Major publishing organiza-
`tions—either electronic publishing en-
`trepreneurs or
`traditional publishers
`seeking new channels—can become full-
`fledged IPs by paying a yearly $10,000-
`membership fee and agreeing to rent at
`least 100 pages. But many of these larger
`providers broker their pages in smaller
`lots to Sub-1P5 who may only put up '
`dozen or so pages.
`As of this writing there are 169 major
`IPs and 801 Sub-IPs—a total of 970
`publishing organizations in all. Wh-
`you consider
`that each of the 970'
`databases consists of information do

`pared on the basis of a real time analysis
`of your answers. In fact. each question
`with its numbered answers is simply a
`menu that helps guide you to one of a se-
`ries of prepared "answer"sheets.

`information stored in computers outside
`the Prestel network to be formatted, in
`real time, for Prestel display. This will
`permit bank-at-home services (now be-
`ing tested) and other utilities requiring
`processing beyond ordinary page
`retrieval.
`Prestel supports no bulletin boards or
`user~entered classified ads. This may be
`
`plays subsets of character strings start-
`ing with G (e.g., Gab-Gain. Gar-Ger,
`etc.). Keying the number adjacent to Go
`produces a new menu page showing a se-

`for Gold accesses a
`menu listing all of

`gold. Another keystroke takes you di-
`rectly
`to

`Pages-
`‘
`Although this process usually takes a
`little over a minute, the number of menu
`layers can be cut almost in half by using
`the more specialized Business Informa-
`tion Index to find gold prices. An even
`more direct Commodities
`Index can
`ShOrten the search time to under 30 sec-
`onds. And Prestel has 17 Specialist in-
`dexes covering such diverse categories as
`agriculture. auto industry, medicine,
`microcomputing,
`shipping,
`travel
`in-
`dustry, and viewdata industry. Since
`each electronic "publication" on Prestel
`has its own mini-index of current stories
`or data; once you have located these in—
`dividual publications you can go directly
`to those pages without having to use any
`of the general indexes.
`Up through January 1982. an exten-
`sive printed directory of the Prestel
`database was available on a quarterly ba-
`sis from the Financial Times (London).
`They recently discontinued this service.
`but there are indications from Logica,
`the US. sales representatives for Prestel.
`that another such publication may soon
`become available.
`The paged structure of Prestel points
`up its primary mission to be a mass
`information medium rather than a com-
`puter timesharing utility. Prestel is not
`designed for word processing, managing
`home finances, or calculating mortgage
`payments. Some of
`the information
`providers have skillfully indexed their
`material to simulate a timesharing util-

`Prestel , continued...
`signed specifically for videotex display
`using color and graphics, the uniqueness
`of Prestel becomes apparent.
`U.S. computer
`information utilities
`(The Source, Compuserve, and Dow
`Jones) lack the range of publishers and
`topics. not
`to mention the display
`capabilities, of Prestel. Competing
`viewdata systems having even greater
`graphics capability—Canada‘s Telidon
`and France's Antiope,
`for example—
`have yet to put up any kind of substan-
`tial database, much less offer their ser-
`vices in the U.S. Lest
`the Prestel user
`fear the low-resolution character graph-
`ics of Prestel are too limiting for sophis-
`ticated
`“office
`of
`the
`future"
`applications,
`it should be noted that
`Presto! plans to offer a series of tiered
`graphics enhancements in the future,
`including full photographic image
`transmission.

`My enthusiasm for the

`
`
`Priced for Business
`My enthusiasm for the Prestel service
`is tempered by one grim reality: the cost.
`Prestel is being marketed as a business
`information service. It was not always
`so. When Prestel was field tested in the
`UK. (starting in 1977), it was intended
`to be an electronic newspaper for the
`masses. The 24 x 40 display was selected
`because it was the maximum resolution
`that could be displayed on a home TV
`receiver using a modulated RF output
`from the terminal. But when Prestel was
`offered to the British public, at a price
`much lower than that now charged in
`the U.S., most citizens still deemed it too
`expensive to replace (or augment) the
`family newspaper.
`find some
`Although one can still
`games and recreational
`information on
`Prestel, 87 percent of the present Prestel
`users are businesses. All U.S. marketing
`efforts, which began in January 1932.
`have positioned the service as a business
`utility carrying a business price tag.
`There are three types of charges on
`Prestel. The first
`is a $50 per month
`membership fee. This is not a minimum
`use charge, but a flat
`fee added to all
`time and page charges. Second, there is a
`charge for connect
`time: 30 cents a
`minute if you don‘t use Telenet
`(you
`must call a Boston area number) or 45
`cents a minute if you access Prestel
`through Telenet. This rate applies any

`Still a third charge is the frame charge.
`Some information providers charge you
`to read their pages. If you access these
`pages from a menu page, you will be told
`the charges before you call up a page.
`These charges can run from 1/,;p. to 50p.
`per page British currency (about one
`cent to one dollar, U.S.). The average
`charge is usually in the Sp. to 10p. (10-

`pages on Prestel are free, however, and
`in my own experience I find that frame
`charges are a negligible part of my other-
`wise substantial quarterly bill.
`
`Pratel Terminals
`Prestel can be accessed in the U.S. us-
`ing any one of three data modem stan-
`dards: Bell 212 (or equivalent), Bell 103,
`and CCITT v.23.
`The Bell 212 standard is the most
`common U.S. 1200 bps standard. but
`128
`
`modems for it are expensive. Also,
`systems for adapting Prestel to la
`computers at 1200 bps require ham“.
`additions (beside the modem), and,
`therefore quite expensive.

`Currently,
