The function is shown in a table-1.
TV system auto detection is set via register [AUTODET] at sub address 00 hex.
00 : forced TV mode (color system is set via [TVM ] at sub address 00 hex.
mode.
01 : European mode (fsc detection : 4.43MHz / 3.58MHz)
10 : South American mode (fsc detection : 3.57954MHz /3.5756MHz /3.5820MHz)
11 : full multi mode
phase)
TC90A92AFG has a H/V sync separation circuit and regenerates HD/VD pulse.
TC90A92AFG has an adaptive comb filter and noise reduction circuit.
M-NTSC : Motion adaptive 3D comb (The sensitivity of motion detection for Y & C are set independently.)
Other color system (Not M-NTSC and not SECAM) : 3D YNR and CNR after 3line comb
SECAM : BPF+3D YNR. 3D CNR is simple motion (Not edge detection).
The phase of HD and VD signals are selectable. (Adapt to 656 format and synchronized with input signal
It is fixed to color system which is selected by [Select FSC], [Select FV], [Select PAL], [Select SECAM].
When there is difference between selected TV system and input TV system, it can’t detect fsc signal for read
There is no relation to setting [Select FV] and input signal gives priority.
Color system is determined by result of vertical frequency detection, fsc detection, SECAM detection.
The order of priority for distinction is 4.43PAL, NTSC, SECAM, ACK.
Note : Field noise reduction for 625 system
Color system is determined by result of fsc detection, vertical frequency detection.
The order of priority for distinction is 3.58PAL, 3.58NTSC, ACK.
The order of priority for distinction is PAL, NTSC, SECAM, ACK.
Color system is determined by result of vertical frequency detection, fsc detection, SECAM detection.
And the distinction of 50/60Hz are independently, there is no priority.
(In case of non signal, it keeps the value of last time.)
