EVAL-ADV7619-7511 Video Evaluation Board to grab a single frame

I am an electronic hobbiest  who works in a telecommunication holding company. I am a beginner in the microprocessors world and want to realize a single frame image grabing project with the help of your EVAL-ADV7619-7511 video evaluation board.

At the moment i am using a Pi 3 and i have a Spartan-3E Starter Board ( I do not have any experience with fpga's yet )

I will have 2 questions about EVAL-ADV7619-7511 video evaluation board and some underlying concept about HDMI receiving:

1.) As it is shown in the Block Diagram of the product it consist of 2 HDMI inputs. What procedure i should follow to grab a single frame from the J2 video jumper pins preferably with the help of Raspberry Pi 3 or Spartan3E gpio pins? 

2.) Let's assume that the HDMI input content is in 4K format. Is this means that the video output pixel clock will automatically synchronized with the input content pixel clock or is it possible to set any video output pixel clock to grab a desired resolution lets say 640x480@60 Hz Industry standard (pixel clock 25.175 MHz) for example.  
Briefly: Is 4K x 2K in --->  640x480@60 Hz (pixel clock 25.175 MHz) out possible?

Thank you!

  • 1) I'd configure the the ADV7612 for the format you want to capture

    2) With the FPGA I'd wait for a Vsync pulse

    3) DE will stay high for one line of active video, capture the line, when DE goes low get ready to capture the next line of video when DE goes high again.

    4) Continue capturing video lines when DE is high unti Vsync goes high.  That would complete one frame of video.

    For the jumpers the controls linles you would be interested in are DE and VS

    The CLK line is the pixel rate used to capture the data.

    Once you get a board, Configure the ADV7612 and scope probe the jumper pins.  It should all become clear then.
