appropriate scan lines. For NTSC, color burst information is automatically disabled on scan line 1-9 and 264-
272. For PAL-M, color burst information is automatically disabled on scan line 1-11 and 264-273 for field 1, 2,
5, and 6. However, for field 3, 4, 7 and 8, burst is disabled at scan line 1-10, 264-272. For PAL-BDGHINc,
color burst information is automatically disabled on scan line 1-6 and 310-318 and 623-625 for field 1,2,5,6.
However, for field 3,4,7,8 burst is disabled at scan line 1-5,311-319,622-625. See the following Figure 5,
Figure 6 and Figure 7.
