Bit
Name
Description
bit 7 MSB ED2FSC
0 when checking the 3.58MHz amplitude during EDTV-II ID
decoding; 1 when not checking the amplitude.
bit 6
ED2RES EDTV-II ID decoding function reset. 1 = reset.
bit 5
bit 4
EDDEC1
EDTV-II ID decoding function detection switching.
Standard values: bit 5 = 0, bit 4 = 1.
bit 3
bit 2
EDDEC2
EDTV-II ID decoding function detection switching.
Standard values: bit 3 = 0, bit 2 = 1.
bit 1
VBLNJ1
Decoding not only of line 20 but also of the 1 line before and after line
20 by the ID-1 decoding function. 0 = yes, 1 = line 20 only.
bit 0 LSB VBRES ID-1 decoding function reset. 1 = reset.
WR
bit 7 MSB AWRES Auto wide function reset. 1 = reset to 4:3.
bit 6
INST
Auto wide switching is performed without the wait time by changing
INST from 0 to 1.
bit 5
bit 4
bit 3
No Use
and TEST
Not used and LSI test bits. Be sure to set all bits to 0.
bit 2
bit 1
UPAREA
Normally. Set the same value as that of PAL bit below.
When PAL = 0, UPAREA = 0, etc.
bit 0 LSB PAL
Auto wide function switching.
525/60 when PAL = 0 and 625/50 when PAL = 1.
bit 7 MSB
ED2ID
bit 6
EDTV-II ID decoding results. 3rd bit of the EDTV-II ID.
EDTV-II ID decoding results. 5th bit of the EDTV-II ID.
EDTV-II ID decoding results judgment. Becomes 1 when a valid
bit 5
EDVLD EDTV-II ID exists. The above noted ED2ID is output and held
regardless of this judgment.
bit 4
ID-1 decoding results. 1st bit: full mode bit.
VBID
RD
bit 3
ID-1 decoding results. 2nd bit: letter-box bit.
VB-ID decoding results judgment. Becomes 1 when a valid VB-ID
bit 2
VBVLD exists. The above noted VB-ID is output and held regardless of this
judgment.
bit 1
AWS
bit 0 LSB
Auto wide identification results.
For 4:3 video, bit 1 = 0 and bit 0 = 0.
For 16:9 wide video, bit 1 = 0 and bit 0 = 1.
For subtitle video, bit 1 = 1 and bit 0 = 0.
