Question:I do the live broadcasting for our church. I use UStream for broadcasting through our website. What I’m looking for is a converter/switch to turn the VGA signal from the Power Point computer into a firewire or USB output to my broadcasting computer. It’s easy to find a USB to VGA for dual monitors, but not a VGA to USB or firewire. Any help or suggestions will be appreciated, thanks.
Answer: If I’m understanding you, and correct me if I’m wrong, You would like to have two sends to your stream video feed that you would like control “switch”. Either way, one or two sends, I understand what your trying to do with the VGA to USB. USB does not have any kind of “converted signal” it’s just raw data. So any type of VGA to USB would have to have some kind of software program that would interpret VGA signals to raw data.
What I would recommend is to use a capture card and split the VGA signal to your program out and Stream Feed? You can find VGA capture cards pretty cheap. You would want to make sure they have fast sample rates so the cheapest ones my not be the best way to go.
If your looking to have a different mix then whats on your Church screens, you would use a separate switcher for broadcast.
I hope this helped and not added additional confusion. If you need more info feel free to leave a comment below….
I am curious as to why there are 2 seperate machines for 2 things that can be done on one machine? If you have dual video out puts you feed one for projector and one for braodcast admin panel on ustream.tv. If the projector cable isnt long enough get a usb to cat5e adapter and run it via eathernet run and the adapters……..or put a wifi nic to a router and run the projector computer online via a router for your ustream panel too……hmmm just curious is all…
Typically you would use one CPU to run Power Point / EZ Worship that would output to a multi-format switcher and monitors. Any other video sources would also tie into that switcher. The output of the switcher would then split to the Live feed & “Capture” computer. You could use one computer but most times you run into hardware incompatibility with EZ Worship & Propresenter and you have no way to monitor it during service.
What we recommend for long cable lengths over 50′ is either, HD-SDI, SDI, VGA/DVI Cat5 Baluns. If you use HDMI to cat5 baluns you man need a EDID sync. Any method other then that would introduce latency and diminished picture.
Awsome!!! Thats why your da man
