Avalon-ST video conversion from 2-symbols per beat to 2-symbols per beat

Hi, I just wanted to write, that I managed to solve the problem. The QSYS solution described above does not work. The conversion using my Verilog code works.

I made one significant mistage though: I was using the wrong clock to read out the data from my HDMI input. I needed to use a PLL to create an exact double-frequency clock from the HDMI clock input. If I use that to drive the output from my symbol converter and input to the pipeline, things work ok.

Cheers,

Klaus
