HA
Horizontal Acquisition: horizontal
sync pulse coming out of the HIP
HFB
Horizontal Flyback Pulse: horizontal
sync pulse from large signal
deflection
HP

Hue
Colour phase control for NTSC (not
the same as ‘Tint’)
I
Monochrome TV system. Sound
carrier distance is 6.0 MHz

Interlaced
Scan mode where two fields are
used to form one frame. Each field
contains half the number of the total
amount of lines. The fields are
written in “pairs”, causing line flicker.
