Quad Video Mosaic example from Bitec

[Altera_Forum]

Hi there! I've been fiddling around with the Quad Video Mosaic (http://www.bitec.ltd.uk/hsmc_qvideo_mosaic_ref_design_vdk.pdf) example and comparing the latency of the video to the VIP Example Design. And I have some questions to the experts ;)  

 1. When using the Clocked Video Input and generating the code from SOPC the VHDL-file is empty, so I wonder if the "interface-code" is done in C?   2. In the user-guide of the Quad Video it clearly says the video-input is downscaled to QVGA size in the "Bitec Qvideo in IP core" / video_*.v, but can someone please tell me where in the code this is done? Because I want to keep the input resolution.   Thank you all in advance!
