LogiCORE IP Video On Screen Display (OSD) v1.0 - Why do I see artifacts around my Text and Boxes, when using the OSD graphics controller in 3 Channel Mode?

Description

Why do I see artifacts around my Text and Boxes, when using the OSD graphics controller in 3 Channel Mode?

Solution

This is due to the third channel asserting 1 cycle earlier than the first two channels.

This problem only affects the 3 channel interface, and is addressed in the next release of the Video On Screen Display IP.

This problem has also been fixed in the Video On Screen Display 1.0 rev patch.

See (Xilinx Answer 35635) to obtain the patch.
