According to Digital, the following products will also be forthcoming soon: Future versions of VAX VTX that will support NAPLPS and Prestel graphics; support for Prestel graphics on the Professional series of computers; support for NAPLPS graphics on the Rainbow personal computer, and educational programs and workshops to support the product offerings and explain how videotex can be used as a business information tool.
Wang Labs of Lowell, Massachusetts also made its videotex debut at the show with a Prestel software terminal emulator for its Professional Computer, promising versions of the software for NAPLPS, the French Teletel and European CEPT protocols in the coming months.
Honeywell's research led it to choose the French Teletel approach based on the Antiope protocol over the North American Presentation Level Protocol Syntax (NAPLPS).
another advantage of Telected is that it can use the Minitel terminal, which is much less expensive than NAPLPS terminals, notes Cleary.
One of the advantages of NAPLPS is that it is terminal independent.
An advocate of NAPLPS, David Hughes, believes that NAPLPS will only catch on as a viable standard when it becomes interactive.
Norpak, a Canadian videotex and teletext equipment manufacturer and one of the developers of the NAPLPS
standard, is working with Samsung on Korean terminal design.
It was the Telidon software, transferred for commercialization to Canadian private sector companies and combined with features developed when AT&T entered the business in the early 80's that eventually became the North American Presentation Level Protocol System (NAPLPS
), the primary industry standard.
We are slowly succeeding in getting people interested in using real videotex protocols like Teletel and NAPLPS
." Trainer is looking forward to tri-standard gateways, such as NYNEX will be announcing in Boston.
A: Well, NAPLPS
is a pretty good object-oriented compression kind of alogithm that was and is misunderstood and in many cases misused.
CitiNet President Richard Koch believes NAPLPS
is the direction in which the industry must move.
The group has developed common specifications for a Minitel-type terminal (including Teletel, but not NAPLPS
) that would suit all their needs.
