I would like to get information regarding the arraignment of NDI decompressed data in the memory.

I am an FPGA design engineer.I have the NDI reference design provided by the platform.I want to change the display interface from HDMI to SDI .
In order to do that i might need to know about the memory address space and the way in which the decompressed video is stored in the memory.
So that i can retrieve the data and plug it in to the SDI interface properly.Where can i find such interface.
Whether the Software side have any information.

The in memory layout depends on the video format. 4:2:2 is standard UYVY, but 4:2:0 is a non-standard format with the chroma interleaved with luma at the macroblock level (eg: 16 pixels of Y followed by 8 pixels of C (r or b). The best source for details is the source code in PixelPack.vhd and PixelPlay.vhd, which are responsible for recording and playing back the raw video images in the example designs.
