    VGA over ethernet or similar

    I've been asked to investigate a solution to a problem we will soon have.

    We have 2 buildings, all networked just fine - with fibre between the 2.

    We will be getting some form of Nettopbox to run our foyer screen and will be putting a second screen in the second building.

    How can I go about displaying the video from the one NTB on 2 screens? There is roughly 100m between the 2 locations.

    A standard VGA-ethernet adapter doesn't seem like it would be much use, as I can't run CAT5 between the 2 buildings.

    So, suggestions?

    Could you set up a VLAN that just the two ports the screens are connected to? I dont know if this is posible as i have never played with VLAN's just an idea!

    VGA cable will cover 100M with a booster (I looked into this a while back), coax will not.
    Other options are to have two PCS and use real VNC to set them running. I have one in the foyer of my school, joined to the domain, no kbd or mouse and with just a network connection. Its an old 600mhz celeron that runs powerpoint all day long, with photo stories and video embeded along with normal slides. Cheap as chips.

    There are other options depending on what you want to display.

    We've got a OneLan system here. It has a feature where NetTopBoxes can be set up as slaves that just dupplicate what another NTB is doing.

    EDIT: It's explained better here.

    I think I may need to explain better.

    We don't wish to buy an extra box, as this would cost us 1300.

    A capture card -> stream -> display would require some form of driver computer at the other end, ie. another few hundred quid.

    VNC would not be suitable due to the possibility of a) lag and b) video being played on the main box, with sound.

    Cable itself can't simply be ran between the buildings as this would mean either having it above ground, and therefore being a lightning risk, or below ground, meaning having to digg up the ground.

    What I want is a system which works via IP to transmit to a receiver - like VGA over Cat5 but via IP instead.

    This is what we do - the machine we use is an old average workstation that we no longer used across the school. Do you not have any old PC's lieing about?

    No, as we have a policy of not keeping old computers.

    I know it's not cheap, but how about an IP enabled KMV.

    1300 for a box?
    A super fast over spec PC would cost no more than 150 to build inc XP licence.

    You can even build a super small form factor one for that price.

    That is the price for the OneLan system, per box.

    We're in an almost identical situation with cabling - 2 buildings with a catenary carrying fibre between them and a requirement for a single digital signage setup managed from reception.

    I was looking at using the Samsung PX400N/PXN400 (i forget the exact part number) screens. They have a built-in XP embedded pc which can run web/flash/java/divx/blah and you can push data out to them rather than stream it continually and it will store on flash memory. The whole thing can be scheduled from an idiot-friendly interface (MagicNet i think it's called) on a standard PC.

    Insight were selling them at the time if you want to get a rough idea of pricing.
