Cross-luminance

Cross luma dot crawl
An artifact that occurs when the brightness information from the luma channel is incorrectly interpreted and applied to the YUV color space.

In television technology, cross-luminance is an undesirable effect that occurs when the brightness information from the luma channel is incorrectly interpreted and applied to the YUV color space. It results in a crawling dot pattern seen on the edges of saturated colored objects. The cross-luminance artifact is most visible along the sharp or moving edges of objects with colored edges; it looks like parasitic dots.
