25.0. "VIDEO over FDDI" by HERON::RUMEAU () Wed Jan 10 1990 08:33

	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 ?

25.1Stay away from FibronicsGRANMA::PDORNANPatrick Dornan, NWSS 8-339-7169Wed Jan 10 1990 10:238
    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.

25.2probably not....GRANPA::PKNIGHTPaul Knight@COL,MultiArea NetworksTue Feb 13 1990 11:2621
    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   
25.3VIDEO OVER FIBERSIOG::SMITHThu Feb 15 1990 13:3018
    	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.

25.5Fibronics is OK and can be managed.BLGVS3::STRATOSWed Mar 07 1990 06:0610
    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.
