Takahiko Fukinuki and the Fukinuki Hole named for him.

Fukinuki is a Hitachi researcher who proposed filling an apparently unused portion of the NTSC spatio-temporal spectrum with additional information that might be used for ATV. The signal that fills a Fukinuki hole is sometimes referred to as a Fukinuki subcarrier. It is extremely similar to the colour subcarrier and can cause an effect like cross-luminance under certain conditions.
