ST_VCEN1
Input signal color encode format indicator
[ST_VCEN1 : ST_VCEN0]
[00]: NTSC
[01]: PAL
[10]: SECAM
[11]: Reserved
ST_VLF
Input signal line number indicator
[0]: 525-Line (NTSC-M,J , NTSC-4.43 , PAL-M,60)
[1]: 625-Line (PAL-B,D,G,H,I,N,Nc , SECAM)
ST_BW
Input signal monochrome indicator*
[0]: Not monochrome
[1]: Monochrome
UNDEF
Input signal detection indicator
[0]: Input signal detected
[1]: Input signal not detected
FIXED
Input signal detection process status
[0]: Detection process in progress
[1]: Detection process completed
Sub Address: 0x18 [7:0]
*Monochrome auto detection is enabled if the color killer setting is ON(COLKILL-bit = [1]).
If the user has deliberately entered the B/W-bit setting, input signal detection is limited to 525/625 line
detection only.
