DESCRIPTION
00: Automatic Sync Selection logic could not find good sync on
H, V, or SOG (Automatic Sync mode only)
01: SYNC on HSYNC/VSYNC
10: CSYNC on HSYNC
11: CSYNC on Green Channel (SOG)
0: HSYNC Active High
1: HSYNC Active Low
0: VSYNC Active High
1: VSYNC Active Low
0: Bi-level SOG (if SOG is active)
1: Tri-level SOG
0: Non-interlaced or progressive signal
1: Interlaced signal
0: No Macrovision detected
1: Macrovision encoding detected
0: PLL unlocked
1: PLL locked to incoming HSYNC
0: HSYNC0 Inactive
1: HSYNC0 Active – There is a periodic signal with frequency
>1kHz and consistent low/high times on this input
0: VSYNC0 Inactive
1: VSYNC0 Active – There is a periodic signal with frequency
>20Hz and consistent low/high times on this input
00: SOG0 Inactive – No transitions detected at the SOG Slicer
output.
01: SOG0 Active – Non-periodic transitions detected at the
SOG Slicer output – possibly valid SOG with a bad slicer
threshold, or simply video with no valid SOG.
10: SOG0 Periodic – There is a periodic signal with frequency
>1kHz and consistent low/high times on this input. This is
most likely a valid SOG signal.
