SUBCARRIER PHASE is sometimes inac-
curately called BURST PHASE, because
the adjustment involves rotating the
phase of burst. However, the
primary effect is to adjust the phase
of modulated chroma.
FIFO: First in, first out.
subcarrier be synchronous with O H at line 1 of the
frame, within about +10 ~ In NTSC, if this requirement is
met at line 1, then the zerocrossing of subcarrier will be
coincident with the analog sync reference point (O H)
within the stated tolerance on
every
line. In PAL, the
requirement is stated at line 1, because the phase rela-
tionship changes throughout the frame.
