Firewire splitter? |
|
|
We're looking for something that would serve effectively as a firewire
splitter. Currently, we have an AV deck that has one firewire output
signal. We are using that to capture video on a Mac. However, we now need
to capture on both the Mac and the PC simultaneously. Is there a product
that will split the firewire output into two signals that can be fed to both
a Mac and a PC simultaneously?
TIA!
Ryan

I may misunderstand, but from what I've read, a switch will only allow you
to use one firewire input in an either-or fashion, not simultaneously. We
need to be able to route one firewire signal to two different machines at
the same time. An A/B switch wouldn't suffice in our situation.

The very nature of firewire disallows more than one host.

If the AV deck has an SVHS output then put that into a DV camcorder( along
with sound)
and use the "Passthru" feature to get the other DV output.

That would be like spliting an ethernet cable into two machines with the
same address. It might be possible but I don't see how.

I am no expert on fire-wire. But it obviously supports two-way
communication, which would present most manufacturers a major
technical obstacle that couldn't be easily resolved.
However, when playing a DV stream, I get the impression that unlike
ethernet, the camera isn't waiting for acknowledgements, it just goes
on streaming the data. So from that perspective, it may be possible to
build a one-way splitter.
My recommendation here would be to also look for a software solution.
There should be no reason why someone couldn't write a 'Firewire
replicator / reflector' That stuffed everything coming into port A out
of port B to daisychain to the next piece of hardware that want's the
stream.
There may even be expensive PCI cards that can do this in hardware.

I was hoping that, because the traffic is essentially going in one
direction, you could send it in two identical streams. For example, I can
see that it would be entirely possible that the deck would offer two
firewire outputs. Why would it not be possible to have a device that takes
the firewire signal from the deck as input and then sends that signal as two
separate, identical data streams on two firewire outputs? Essentially,
that's what the deck would be doing internally, right?

Well you have to remember that this is digital and not analog. For my
satellite system which receives MPEG2, there is a switch that allows me
to take the input from two satellites and plug it into one receiver.
It's an inexpensive item. However to go the other way, one satellite to
multiple receivers, you need a multiplexor, that's an expensive item
that I would say is analogous to an internet gateway box. So it is
possible that it does exist for firewire but I don't know if anyone has
every built it. The client/server idea someone else mentioned might be
doable, if you could have firewire over ethernet then that would open up
a lot of possibilities.
