Frage von StephanG:
Hello!
The issue is here is already posted more often, but unfortunately not really solved.
I have the following setup:
- 3x DV Cam via firewire s.Videomischer Datavideo SE-800
- DV Out of the mixer s.einen Firewire Hub
- The Hub 2 notebooks for streaming
- At the Stroke 1 additional notebook for recording
Unfortunately, with the stroke is not entirely successful. I already have the big 20 port Kramer tested synonymous and the 5 Port of video data itself.
From three devices on the hub, the volatile matter and the calculator will lose the connection to the mixer and times depends probably synonymous throughout the Firewire bus.
Can the s.unterschiedlichen operating system is? I have Vista, XP and Linux
Or is it a problem with Firewire?
How would you do that, the DV signal several devices available to?
Thanks a lot!
Stephan
Antwort von robbie:
Firewire, you can not simply distribute.
With a firewire hub, you can multiple devices s.einen Calculator attach, but not a device s.mehrere Calculator. This is technically impossible.
An alternative would be out of your analog mixers go, and via an A / D converter to digital in the streaming computer. Since you will have no problems, and the slight reduction in quality is not noticeable in streaming!

Hm, exactly that I've almost thought. Unfortunately, applying the manufacturer but as ....
My fallback is now, firewire out of the mixer just for the recording to use, then I need the high quality streaming and on the Y / C, S-video or composite to make. We have already noted a difference vsin of sharpness but that is to live with.
Thank you!

times so that I would confront the Manufacturer. Maybe yes, the experience with their products? * fg *

Have I understood correctly, the Kramer VM-20FW is unstable compounds S.3? How long are the routes? Are Aufholverstärker between running? The Kramer should ansich can afford.
Antwort von StephanG:
The kramer port 20 has two input ports A + B, s.die device you can attach that to deal with them that 20 clients behind the tap. Apparently neither can nor DV Cams SE-800 bypass.
It is the 20 ports synonymous in 5 groups together as a hub switch and it works, unfortunately, not synonymous.
Have meanwhile the Datavideo 5 Port Firewire Hub get it because even the manufacturer recommends, but that does not synonymous, s.dem third device kracht it together ....
The lines are short, about 1.5m with the cables in the SE-800 were there.
Antwort von robbie:
It can with DV devices not working, schaut euch doch mal to the protocol. As a bidirectional connection is working. The devices come immediately somehow confused when they no longer know who is now of who gets what. The DV Firewire connection is not a stinknormale digital signal transfer, but subject to a protocol used for 2! Device is intended.

How will this be used in professional environments be solved?
Antwort von fourCCrider:
hallo, StephanG!
Would it be possible, with the mixer into the computer and of everything
via Gigabit LAN network - is certainly less problematic.
(with us in the TV studio, the recording, editing suites and video server as synonymous PC network connected, if still synonymous over thicker lines)

Antwort von StephanG:
4CC Hi!
Good idea, but how come then the DV signal from the first calculator, s.dem the console depends s.die another calculator?
Stephan
Antwort von fourCCrider:
hi stephan!
exactly what I said - between all calculators Gigabit Ethernet use tversity to stream with VLC or or .... as streaming software ..
.. yes, there still synonymous with the standard ieee1394 network connection of windows, perhaps it is with multiple firewire ports on the first machine which trick - but I think simple, reliable and vsbilliger is a GB-lan - with reasonably fast computer (via pci-express or affiliated onboard-) lan interfaces are likely deal with more traffic than 1 dv-stream needs.

Antwort von StephanG:
hm, there is the problem that it is transcoded by VLC, for example, and then later by WME ....
Antwort von robbie:
How will this be used in professional environments be solved? not with firewire, this is actually a transfer of consumer interface, and for live applications synonymous unsuitable because of the 12 frames delay.
professionals use sdi / hd-sdi, which has no offset and can be freely distributed.
why everything is so complicated and pointless?
the solution to the problem was already written above, namely the internet stream of the analog signal of the mixer used. the unschärfe which one wants to see because, I do not know, except perhaps you use a cheap digitizer.
With this solution you have the fewest problems, it is 1000 and tried out the different notes you not even if it is white.
