APPENDIX 3—COPY GENERATION MANAGEMENT SYSTEM (CGMS)
The ADV7174/ADV7179 supports the CGMS, conforming to
the standard. CGMS data is transmitted on Line 20 of the odd
fields and on Line 283 of the even fields. Bits C/W05 and
C/W06 control whether or not CGMS data is output on odd
and even fields. CGMS data can only be transmitted when the
ADV7174/ ADV7179 is configured in NTSC mode. The CGMS
data is 20 bits long, the function of each of these bits is as shown
below. The CGMS data is preceded by a reference pulse of the
same amplitude and duration as a CGMS bit (see Figure 57).
The bits are output from the configuration registers in the
following order: C/W00 = C16, C/W01 = C17, C/W02 = C18,
C/W03 = C19, C/W10 = C8, C/ W11 = C9, C/W12 = C10,
C/W13 = C11, C/W14 = C12, C/ W15 = C13, C/W16 = C14,
C/W17 = C15, C/W20 = C0, C/W21 = C1, C/W22 = C2,
C/W23 = C3, C/W24 = C4, C/W25 = C5, C/W26 = C6, C/W27
= C7. If Bit C/W04 is set to a Logic 1, the last six bits, C19–C14,
which comprise the 6-bit CRC check sequence, are calculated
automatically on the ADV7174/ADV7179 based on the lower
14 bits (C0–C13) of the data in the data registers and output
with the remaining 14 bits to form the complete 20 bits of the
CGMS data. The calculation of the CRC sequence is based on
the polynomial X6 + X + 1 with a preset value of 111111. If
C/W04 is set to a Logic 0, all 20 bits (C0–C19) are directly
output from the CGMS registers (no CRC is calculated; it must
be calculated by the user).
