NTSC/PAL Encoder MM1394

* Note 4 : 4 Chroma signal measurement (NTSC mode)

Chroma level ratio is the ratio between each color signal level and burst signal level.

Each color phase is 180° from burst signal phase (given B-Y axis as 0°).

* Note 5 : 5 Chroma signal measurement (PAL mode)

Assume burst 135° side signal as color-1, and burst 225° side signal as color-2.

Phase measurement is done assuming the middle of burst-1 and burst-2 phase as 180° (given B-

Y axis as 0°).
