Hello
I am developing a system using Video Image Processing from Altera
I need to convert a RGB 4:4:4 (24 bits) video to YCbCr 4:2:2 (20 bits)
To do that, I am using the following components:
Clocked Video Input
CSC (Color Space Converter) -> RGB to YCbCr
Chroma Resampler -> 4:4:4 to 4:2:2
Clocked Video Output
The CSC is the only component that don't need the image size as parameter
My problem is that the video source can be in both HD or SD so I would need to dinamically adjust the components
Is there anyway to do this dynamic reconfiguration?
Or will I need to instantiate two of each component and select which one to use based on the video input format?
Thank you!

As I understand from your description, you have two sources which have an effect of changing the image size. Some of the solutions can be:
1. Have two designs for two sources and configure FPGA with the relevant design on-the-fly based on the source that you have selected.
2. Keep the bigger design among the two and see if there is any way to slice the parameters and signals of the bigger design to yield the parameters/signals of the smaller one.
