Examples of "naplps"
technology was deployed in Canada, both as a way for rural Canadians to get news and weather information and as the platform for touchscreen information kiosks. In Vancouver these were featured at Expo 86. The kiosks became ubiquitous in Toronto under the name "Teleguide," and were deployed in many shopping centres and at major tourist attractions. The latter city was the North American nexus of
and the home of Norpak, the most successful of
-oriented developers. Norpak created and sold hardware and software for
development and display. TVOntario also developed
content creation software.
(North American Presentation Level Protocol Syntax) is a graphics language for use originally with videotex and teletext services.
was developed from the Telidon system developed in Canada, with a small number of additions from AT&T Corporation. The basics of
were later used as the basis for several other microcomputer-based graphics systems.
London, Ontario - based Cableshare used
as the basis of touch-screen information kiosks for shopping malls, the flagship of which was deployed at Toronto's Eaton Centre. The system relied on an 8085-based microcomputer which drove several
terminals fitted with touch screens, all communicating via Datapac to a back end database. The system offered news, weather and sports information along with shopping mall guides and coupons. Cableshare also developed and sold a leading
page creation utility called the "Picture Painter."
was also part of the NABTS teletext standard, for the encoding and display of teletext pages.
-based services were developed by several other joint partnerships between 1983 and 1987. These included:
The resulting system emerged in early 1983 as
, while the transmission method that encoded information into the vertical blank interrupt of a TV signal became the NABTS standard. Major articles in "Byte Magazine" introduced the
system to a wider audience, spread over a four-month period in the February, March, April, and May 1983 issues. With the standard complete, the U.S. teletext plans started moving forward.
' ability to draw complex graphics was particularly interesting to U.S. information vendors such as Compuserve, as it allowed them to draw network or advertiser logos.
In 1981, two amateur radio operators (VE3FTT and VE3GQW) received special permission from the Canadian Department of Communications to carry out on-air experiments using
syntax which was technically not legal at the time because it was a "coded transmission". Following their report on the success of the tests, the DOC then permitted general use of
on amateur radioteletype. This was reported in the ARRL Radio Handbook for several years following.
lived on into the early 1990s as the graphical basis for the Prodigy online service. Some bulletin boards were able to serve
content to callers on their 1200 and 2400 bit/s modems. But the technology's chief advantage in an era of slow telecommunication - its ability to encode complex graphics in terse object commands - became moot as data communication speeds increased and raster graphics compression became popular.
Various two-way systems using
appeared in North America in the early 1980s. The biggest North American examples were Knight Ridder's Viewtron (based in Miami) and the Los Angeles Times' Gateway service (based in Orange County). Both used the Sceptre
terminal from AT&T. The Sceptre contained a slow modem that connected over the consumer's telephone line to host computers. The Sceptre was expensive whether purchased or rented. Despite huge investments by their parent companies, neither Viewtron nor Gateway lasted into the second half of the decade. Another system - Keycom - was developed by a joint venture of Honeywell, Centel (since acquired by Sprint) and the Chicago Sun Times newspaper. Keycom used a proprietary
In the late 1980s, Tribune Media Services (TMS) and the Associated Press operated a cable television channel called AP News Plus that provided
-based news screens to cable television subscribers in many U.S. cities. The news pages were created and edited by TMS staffers working on an Atex editing system in Orlando, Florida, and sent by satellite to
decoder devices located at the local cable television companies. Among the firms providing technology to TMS and the Associated Press for the AP News Plus channel was Minneapolis-based Electronic Publishers Inc. (1985–1988).
After most of the commercial efforts had ended,
received a fresh breath of life as the basis of the Prodigy online service. In the time between efforts like Viewtron and the launch of Prodigy in 1988, personal computers with the ability to view
graphics with ease had become common, and modem speeds had increased to the point where the data was no longer overwhelming. After a promising start, Prodigy management invoked a series of blunders that seriously upset their customer base, and the arrival of the World Wide Web in the mid-1990s killed it off.
Hosted on a fault-tolerant Tandem/16 minicomputer, Viewtron used the
graphics language to provide a user interface that was graphically sophisticated by the standards of the time. According to Chip Bok, screens were crafted so as they loaded, elements would be drawn in sequence, "the way you would tell a story." Unlike HTML,
allowed screen elements that remained unchanged through different pages of a story to remain static, an important concern with the low bandwidth 300-2400 baud modems then in use.
NABTS, the "North American Broadcast Teletext Specification", is a protocol used for encoding
-encoded teletext pages, as well as other types of digital data, within the vertical blanking interval (VBI) of an analog video signal. It is standardized under standard EIA-516, and has a rate of 15.6 kbit/s per line of video (with error correction).
Telidon saw limited use after that, in niches like informational displays in airports and similar environments.
did appear in several other products, notably the Prodigy online service and some bulletin boards. Telidon had a more lasting legacy on the hardware side; its NABTS communications system found re-use years later in WebTV for Windows.
-based systems (Teleguide) were also used for an interactive Mall directory system in various locations, including the world's largest indoor mall, West Edmonton Mall (1985) and the Toronto Eaton Center. It was also used for an interactive multipoint audio-graphic educational teleconferencing system (1987) that predated today's shared interactive whiteboard systems such as those used by Blackboard and Desire2Learn.
Sports Plus Network was a service run by SportsChannel in the late 1980s and early 1990s that filled the airtime when SportsChannel was not on the air. It was an "automated" service that featured sports news and scores displayed using
protocol was later re-used for the basis of the graphics of the Prodigy online service, which began in 1988. But this was wholly directed at microcomputer owners running special software. It made no attempt to seek users with dedicated terminals.
After college, Canter travelled to New York City to help his friends build a music studio called "Noise New York." During this time Canter learned about laserdiscs, laser light shows,
, pro audio and video equipment, and a then-new technology called videodiscs. Canter has also worked as a taxi driver in San Francisco, California.
In the late 1980s and early 1990s, SportsChannel ran a service called Sports Plus Network, which ran sports news and scores while SportsChannel was not otherwise on the air. The screens, which frequently featured team logos or likenesses of players in addition to text, were drawn entirely with
graphics and resembled the loading of Prodigy pages over a modem, though slightly faster.
Although there were numerous attempts to introduce
services in North America, none of these was successful and eventually shut down. A number of special-purpose systems lived on for some time, similar to Prestel's lingering death, but the widespread rollout of internet access in the 1990s ended these efforts.
