I am working on a project which requires video networking and I would like some informations about companies which will able to propose some kind of materials allowing me integrate video paths in FDDI. I have already found one called FIBRONICS which propose an FDDI Network system "FINEX" using video digitizers and compressors but I would like to find other companies (the best would be that they have anchors in Europe) which propose other solutions. Can anyone help me my quest ? Frederic

Fibronics is a competitor. I wouldn't deal with them at all. If
you must, keep your customer a secret, because they will go after
your business themselves.
I don't know of video over FDDI companies, but will pass info along
if I get it.

| 25.2 | probably not.... | GRANPA::PKNIGHT | Paul Knight@COL,MultiArea Networks | Tue Feb 13 1990 11:26 | 21 |
From the information I have seen (limited, I admit), reasonable video
over FDDI is not going to be available for quite a while. Sure, you
can digitize, compress, and transmit video, but there are serious
problems of synchronization, not to mention the loss of quality with
the levels of compression you need. For example, the studio standard
for uncompressed NTSC (standard US TV) digitization requires 143
megabits per second.
You could probably manage to get one of the video-conference type
codecs (PictureTel, Compression Labs, etc.) to feed through FDDI, but
that's not an answer to most people's expectations of "video." If you
really need good quality video over fiber, you don't want to squeeze it
through FDDI. You will need a dedicated video fiber optic system.
You will almost certainly have to end up talking to
Grass Valley, which is a subsidiary of Tektronix. They appear to have
about 75% of the market for high-quality video transmission over fiber
optic links. Again, don't mention the customer name to them too early;
but they will be happy to provide consulting or proposal assistance.
Good luck! Paul

| 25.3 | VIDEO OVER FIBER | SIOG::SMITH | Thu Feb 15 1990 13:30 | 18 | |
I would agree with 2. you should consider a dedicated fiber
for video. DECsite in Ireland are in the process of installing a
campus lan for a large university. The caple plant installed for
the backbone is FDDI compliant. As part of the solution a multi
channel tv distribution system was proposed and accepted. We will
be using STC MULTIVIEW which will support 8 video and 16 audio channels
over 62.5/125 cable.

| 25.5 | Fibronics is OK and can be managed. | BLGVS3::STRATOS | Wed Mar 07 1990 06:06 | 10 | |
I believe Fibronics is the only company that have a working prototype
that will soon become a product. You have to be careful though, because
they are competitors in a number of areas in the networking space.
Their prototype is currently tested in a large FDDI project in Italy
and, I believe Valbonne has a working (business) relationship with
Fibronics with a video aplication.
