Video and Image Processing Scaler II IP Question

[Smith222122]

Hi there,

I am wondering, when inputting a video stream with a resolution of 1920 x 1080p to the scaler II IP core and scaling this video down to 1280 x 800p, do I always need to then output this video stream from the scaler into a framebuffer before I input this video stream into a Clocked Video Output IP core? It seems like my CVO underflow continues to trigger no matter how large I make the input FIFO of the CVO.

My scaler runs at 100 MHz and my CVO outputs video at 65 MHz. 

Thank you!

Hi Smith,

Good Day.

May I clarify the actual video format first? Based on the EIA/CEA-861 standard.

Thank you.

Hi Smith,

We do not receive any response for a while from you on the previous reply.

I believe this is similar as "Scaler II IP Core Causing Underflow on Clocked Video Output IP"  case.

Hence I will close the case.

If you have a new question, feel free to open a new community forum case to get support.

Thank you.
