Hey lists, This is somewhat OT, but just a little. I want to capture live (5 fps?) 1024x768 VGA and make mpeg or something I can stream over the net. The application is this: Developer meetings and conferences. "all" speakers bring their laptops and hook up to the 1024x768 projector. I want to broadcast that over the net. (I may point a web cam at the presenter too and have that as a 2nd feed.) I do not want to load anything on their laptop. I 'know' it is easy, cheaper, and better in some ways, and it may even happen in some instances, but for the most part, I never want to even ask a speaker to do it. There just isn't enough time to to make sure it works, etc. A hardware based solution is much more ... good. The plan is to have a laptop or small PC sitting under the projector that somehow gets the same VGA as the projector. Some projectors have a VGA out, not sure how standard that is. I can deal with an external device that uses USB or Ethernet, or a pci/pcmica card in the box that will do the encoding. I found this: https://ssl.epiphan.com/order/order.php?pid=1 - that will do what I need, but $400 is a bit much (I need about 5 or 10 for conferences that have multiple sessions going at the same time.) I am kinda doing this on my own - the first step is to get one for the local user group meeting I attend. If that works out, then I may get some more and loan/rent them out. Thus the desire to find a cheaper solution. I found things relating to KVM over IP, can't figure out if these will allow me to capture/stream. http://www.zantech.com.au/peppercon/eric-express/ $100 aten CN-6000 http://www.aten.com/products/productItem.php?pcid=20050103163647001&psid=20050107105033001&pid=20050224141359008 $400 http://okvm.sourceforge.net/kvmoverip.html - pretty sure that requires a pci card in the box generating the video (so no good.) Thanks for taking the time to read this - any pointers welcome. Carl K
i am a bit confused to what you want...do you mean you want a scan converter? you can plug a vga out of the laptops to the scan converter, take another vga from the scan converter to a projector, and a svhs or composite out from the scan converter to the encoding machine you can buy them for about 200 USD or less or do i misunderstand your question? adam ..on Thu, Mar 16, 2006 at 03:44:44PM -0600, Carl Karsten wrote:> Hey lists, > > This is somewhat OT, but just a little. > > I want to capture live (5 fps?) 1024x768 VGA and make mpeg or something I > can stream over the net. > > The application is this: Developer meetings and conferences.

Adam, First the disclaimer: I am new at this, and so I may not have 100% understanding of terms like svhs or composite. That said, You are close, but svhs or composite isn't 1024x768 - it is 640x480 or whatever this chart says: http://www.geocities.com/cplarosa/video/vidres.htm I am not targeting any TV display - my target is other computers running win/mac/linux/whatever that can decompress streaming video and display it on a full blown monitor. (I haven't figured out how much bandwidth someone will need for this.) follow?
