I'd like to use my camcorder for video conferencing.
On the one end, the camcorder outputs HDMI. On the other end, the PC takes USB input. How do I convert the HDMI video feed to a "webcam" USB connection in real-time*?
* Where "real-time" is defined as latency of 300ms or less.
UPDATE:
- The recorded video must be at least 1080p, 30fps.
- The target PC is a low-end laptop so assume I can't use a built-in capture card and the built-in CPU is weak.
- I am more interested in finding a solution that works than one that is cheap.
- I must use a camcorder (instead of a webcam) because the camera-man is expected to use manual controls (e.g. lighting, zoom, focus, view-finder) to shoot a broadcast-grade video. Imagine I am shooting a TV show consisting of individuals in remote offices chatting with one another. The video conferencing nature means low latency is vital. The TV show means the camera must be broadcast-grade.
What ports does the laptop have? USB is going to be too slow (unless it's 3.0). Does it have an ExpressCard port?

Also, are you recording each end separately? You're not assuming 1080p delivery to the remote end are you? – LilCodger – 2013-03-12T17:30:04.063
@DavidSchwartz, you can assume the existence of USB 3.0 ports but no ExpressCard. I'm using the Lenovo Yoga as a reference. – Gili – 2013-03-12T23:36:35.107
@LilCodger,
Can you record in the camera and use the output video to feed the webchat?
. That's precisely what I'm trying to do but can't figure out how. Yes, I will be sending 1080p over the network using a very big pipe. – Gili – 2013-03-12T23:37:43.220So broadcast grade camera + 20+Mbps pipe but "low-end laptop"? Okay then. I have used BlackMagic products for streaming before via Skype,Adobe Flash streaming, and other methods. I have not used the Intensity personally, but if you have USB 3.0 available I would expect it to work, depending on your software. Latency on BM hardware tends to be pretty low. Latency on your software I can't speak to, but streaming latency is usually pretty horrible (20+ seconds on QuickTime and WMP solutions). – LilCodger – 2013-03-13T00:09:31.167
Also, if your camera supports DV (IEEE 1394, firewire) output, I have also used DVDriver with DirectShow compatible software (like Skype). Never at 1080 though. http://www.trackercam.com/TCamWeb/dvdriver.htm
