HD49801FB
• Odd/even determination signal
This is determined by latching CHD on the falling edge of FV.

• IDO for PAL/SECAM
The change point agrees with the falling edge of C.SYNC.

IDO
In PAL mode:
ID = high: Modulates at R-Y + polarity
ID = low: Modulates at R-Y – polarity
In SECAM mode:
ID = high: B-Y output
ID = low: R-Y output
The (R-Y) polarity inversion in PAL mode is performed in the encoder that follows the digital interface.
