  1. I am gonna start a project with the following setup (attached the overview). I am doing a scaling function on the FPGA. I was thinking about the Nexys Video Development Board. This board got an DP output. But it only has HDMI as input/output. I know that HDMI is almost DVI. I don't think I can use an adapter. I need the DVI-connector and not HDMI-connection. Prioritized is the DVI--> FPGA--> DP connection. Next comes DP--> FPGA--> DP. I need the DVI input according to the picture. I have been reading about a FMC DVI I/O on Avnet but I can not find it. Any help to solve this hardware/component setup would be much appreciated! (Which FPGAs and FMC to use) Regards
  2. Hi, I'm using the dvi2rgb/rgb2dvi cores (latest repository version) to make a simple passthrough in the FPGA and have huge issues with the EDID memory. Has it been confirmed at some point that the default 720p edid settings work properly with a GoPro Hero5 camera? I tried loading the default EDID, a properly cooperating monitor's EDID, prepared numerous EDIDs myself - every single one seems to fail so the camera is setting itself to the lowest supported resolution. Had a go with a Panasonic DMC-G3 camera too but it behaves the same way. Both sources work properly when connected directly to the monitor. The EDID values are being read properly, this has been verified on an oscilloscope (the camera seems to be reading the 128 edid bytes twice though).
  3. The dvi2rgb IP core seems to take anywhere from 5 seconds to 20 seconds to acquire synchronization and display incoming HDMI data. The datasheet says the process could take up to 1 minute. The pixel clock achieves lock quickly, it's just the data/syncs that takes some time to appear. I hate to complain, because the core is provided free of charge with the Nexys Video card, and seems to work quite well otherwise, but Is there any way to speed up the acquisition time, or perhaps in a future update?
  4. The HDMI2USB project aims develops affordable open hardware options to record and stream HD videos (from HDMI & DisplayPort sources) for conferences, meetings and user groups. Our current focus is on around custom gateware running on FPGA hardware, our gateware if fully open and can be found on github. The gateware allows for both full matrix functionality and capture via either USB or Ethernet. A control terminal is also available giving the computer complete management of all functionality. We have been using the Digilent Atlys as a prototyping platform and are investigating also supporting the Digilent Nexys Video. We are also developing our own hardware the Numato Opsis. As an open source project, we'd love help continuing to develop new features and functionality. We are actively seeking assistance: For video recording individuals+teams: Be an early adopter; get a board, start using it, report back to us with feedbackFor software/FPGA developers: Get involved in contributing code both to the capture software + FPGA stackOur aim is this becomes the defacto, incredibly affordable and easy to use video recording hardware for conferences, meetings and user groups worldwide.

  6. Hello, The older Atlys boards had a Spartan-6 FPGA which meant the highest progressive resolution supported by the HDMI input and output was 720p (which was always frustrating). I was wondering if that had changed with the newer Series 7 devices like the Zybo or Nexys Video boards? I noticed that hamster was able to get 1080i working. Are SERDES even able to do 1080p theoretically? Thanks for your help! Tim 'mithro' Ansell
