I recently tried researching how to mix/record not so cheap cameras on a PC/Laptop/RasPi analogue. Remarkably tricky, because of the data rates involved. So far I have not seen a single affordable, open source compatible solution for "just" taking hdmi signals in. At least not for 1080p. I have modest hopes that such controllers might show up in the next years, maybe using USB 3 technology. There is also a Raspberry Pi module "in the works", which may be capable of at least streaming compressed 1080p from HDMI, but I'm not holding my breath.

Was this the module you were looking at? http://www.auvidea.com/index.php/theme-styles/2013-06-22-21-23-34/raspberry-pi-hdmi-in http://www.auvidea.com/index.php/theme-styles/2013-06-22-21-... I'd heard the GPU was getting better docs, and I wondered if it would help handle this.

  According to the site the board is already in production, but there is no further indication on when or where to buy. I don't think GPU docs will help enough. And then there's the issue of a completely new RPi2 SoC to consider...

    Gpu docs wont, but videocore docs would, sadly Broadcom is hostile and will most likely never release low level stuff, same goes for mipi dsi LCD interface. Pee2 uses same videocore, only difference is CPU IP.

  From the writup on this page it seems Pee camera module works in RAW mode. This is weird and uncommon.

define cheap? Those guys are working on hdmi-to-parallel CSI input converter for Olimex A10/A20 Linux SBCs https://videobrick.wordpress.com/ https://videobrick.wordpress.com/ Then there is this guy cooking hdmi-to-mipi CSI for the Pee http://theiopage.blogspot.com/ http://theiopage.blogspot.com/ then you have chinese HDMI over Ethernet extenders (~$75 free shipping), they compress 1080 to mjpeg, you can throw away receiver and just slurp that data into your computer https://hdmiextender.codeplex.com/ https://hdmiextender.codeplex.com/ 1080i hdmi pcie capture cards start at $40, $50 for 1080p with borders (not 1:1), $65 Trident chipset proper 1080p grabbers
