LogiCORE IP Video On Screen Display (OSD) - Why are Operations Limited to Even Pixel Boundaries when using the OSD in 2 Channel Mode?

Description

Why are operations limited to even pixel boundaries when using the OSD in 2 channel mode?

Solution

When the Video On Screen Display (OSD) is used in 2 channel mode for YUV-4:2:2 systems, operations are limited to even horizontal pixel boundaries.

This is done in order to avoid color boundary artifacts.
