Our idea has been used in actual products
It is a 3-dimensional Y-C separation filter for NTSC television
signals. Conventional so-called 3-dimensional Y-C separation filters
are actually the combination of horizontal 1-dimensional filter and
adaptively switched temporal or vertical 1-dimensional filters,
depending on still and the other for moving scenes. The proposed
filter is a real 3-dimensional filter (composed of horizontal
1-dimensional filter and non-separable vertical-temporal 2-dimensional
filter), and as a result crosscolor is very much suppressed even for
slowly moving pictures.
Mitsubishi developed its IC and named Super Digital Y/C Separation.

The circuit is also used in Laser Disc Players
from Pioneer, where it is called High Resolution 3-D YC separation.
