Videotext for your ST computer ?
Meanwhile we have got two different lines of deoders . The first
one by the firm 'Print Technik' for about 298 marks and the
second one produced by 'H & T' , from Berlin ,for 249 marks.
We decided to take the second version because this system is also
able to work with the latest VT-technics called 'TOP Decoder' !
The installation is very easy: you'll have to put the decoderbox
into the centronics-printer-port and conect it with the contained
power-supply plug ( already fixed to the right values ).Then we
need the videosignal ! Therefore we've got some different ways:
we can get it from a videorecorder with video-output or SCART-
output ( also called EURONORM-plug ) or from a TV-tuner by
Phillips or Vobis.At the moment we're not able to get a video-
signal from a normal TV.
Afterwards one has got to start the included software from disk
or harddisk.Their's no protection though you won't have any
problems ! Then the computer wants to if he should load the three
top-pages and after answering 'yes' he tries to load them into
the avaible memory.Only ARD (german TV) and ZDF ( also german )
videotext allow this.Then we get the mainmenue on page 100 and
see the typical videotext page with the number of the actual
page,the sign of the TV-station,the date and the time.Under these
things we've got the videotext-page and another menueline with
several systemfunctions:'well done' !
The monochrome user is able to choose two different ways to show
the picture:first in the rasterplotting or in a simple white
plotting.The colour users can't choose,they see the picture as
watching with a colour TV.
I think it is very well done that the program is able to load the
main pages after starting it and also loaded pages after watching
are safed into the memory which means a faster and more
comfortable working with this system.While searching a page the
user can press 'H' to stop the searching.At this point we've got
a very interesting function: the possibility to safe or print a
page or a text.We can safe the text using ASCII format and then
work on them with each other system.The pictures can be safed in
Degas format in all different resolutions.And we've also the
function to print the text or grafics.Therefore we can use some
different refiners for different printers ! One has got the
chance to print by using the centronics-port or the seriall-port.
We can't print with directly with the Atari laserprinter,
therefore we have to use the Laserbrain-FX-emulator,but this has
got no negativ effects !
But their will be problems if you've got an instable videosignal
or if their is a rustle or some other disturbances.Then we have a
multilated page and you must wait some seconds to get a correct
output.It's also possible that the decoder is hacing,this means
that you're not able to make any inputs or if you want to
make, you have to make them as slow as possible.
I think it is disturbing that the pages needs some passages to be
installed right and not as used by the original that the user
will see the page after the getting the last information-bit.
Another possibility is to load all pages after starting the
program and the user is then able to get the pages very fast. The
ST might have enough memory to safe all pages !!!!!!!!!!
Another error:if you want to change the time by using the
function clock,then you'll get a system crash.After reading the
manual ( diskfile ! ) we get to know that this function is
another expansion.They should change this part and tell the
reader that he's not allowed to use it.
The programers should try to produce an update and avoid such
simple errors.The TOP-decoder does his work without any mistake.
The user is able to work with his mouse and he needs no start-
page or index.But at the moment you can use this TOP-decoder only
with the VT-signal by ARD and ZDF !
Now we wanted to test if we're able to get other VT-signals by
some other TV-stations and then to work with them.First we tried
all the third channel stations ( HR 3,WDR 3,SWF 3,BR 3) and then
the SAT 1 and last but not least the videotext by sky and
superchannel.The system was able to work with all different kinds
but you should clean the memory before switching to another
station because if not it is possible that you'll first get the
old page.
After all I think we can say that this decoder is made well. The
hardware was well done and only the power-plug could be better .
Instead of the die-plug I would take a normal plug.Positiv is the
little LED which shows if the decoder is activ or not.The
software has got only some little mistakes and the VT-decoder is
a cheap possibility to get a VT-decoder who hasn't got the chance
to get a new TV or to change his old TV station.Also a cheap
chance for all people which have got only a clolourmonitor
because they can conect the decoder with a videorecorder !!!!
