Video Processing Subsystem Master/Slave clock rate
As Video Processing Subsystem replaces scaler, deinterlacer, chroma resampler, etc, VPS is recommended for new designs. But there is one concept that vanished from Scaler (Old stand alone version) --> to VPS. Different master and slave clk in Axi-Stream ports.
With VPS, I want to perform a simple live up-scaling (from 1024x768p@50 to 1280x720p@50) and I want to keep the same frame rate. Why do Master & Slave interfaces in VPS share the clk? Obviously, the pixel rate would change as the resolution has increased.
My source of video (1024x768p@50) is 40MHz pixel-rate and I want to transmit the scaled video (1280x720p@50) through an HD SDI at 74.25MHz. How I am supposed to manage the different clk rates?
