In theory if you had a fast enough computer the device could do both (it's all software based anyway), but that would require a lot more work and money, as in addition to developing the software, the device would have to be HDCP compliant. In addition, because it is limited to 720p, it would be even less appealing. Basically it's a $150 turd. I would suggest contacting the manufacturer to verify it will fulfill your requirements before purchasing.
It doesn't have to be HDCP compliant, it's using the exact same methods that i use my K7 for to plug into my HDMI in on my 50" Plasma. Of course i can copy my own Videocameras output, there is no need for copy protection.
I plan to use my 10" tablet, or 15" laptop, both of which have USB, and HDMI output, but no input.. The USB to HDMI adapter does exactly that, it plugs the HDMI cable from my K7 into the USB port, than any Video editing application will treat it as a Camera in. At the moment, if i used a analogue USB TV tuner with AV IN i could use that, but i want HDMI connection, which is what those converter boxes do.
Anyway just thought someone else may already be using a particular one, I will give it a go myself. There are plenty of device that already do what you say, like Blackmagic devices.
Blackmagic Design: Intensity
But they are not bus powered, and thus not portable, for which i'm after, but they work fine with the K-7 to record directly from LiveView.
So i think you may be confused, BTW manufacturer obviously assures me it will work, every YouTube video makes me think it will too, and why does the BlackMagic work fine for me then? Sorry but perhaps only comment on things you have actual working knowledge of, but i do appreciate the warning and thoughts.
What do you think these adapters are for then?
I also only want to do 720p, because I'm using a K-7! Anyone else ever done anything like this?
