Hi, Everybody.
I faced problems using a TVP5150AM1.
I am developing a car AVN with PLDS Loader + TCC8900 CPU(Telechips).
In NTSC mode, there is a little bit flicker noise also. But in PAL mode, there are lots of flicker and 'Rainbow' effect(Please, forgive me. i don't know the exact term instead of Rainbow effect.)
DVD Title what i tested is PAL format.
I took photos in NTSC and PAL mode as belows.
1'st Picture is one In NTSC and 2'nd is in PAL Mode Setting. Since above pictures are pause images, it is difficult to see flicker noise.
Same problem is occurred even i use a TVP5146 + DVD CVBS configuration.
For reference, TVP5150AM1 PAL Setting Values are;
Register Value
03h 29h // enable Auto switch signal for SECAM
04h DCh // enable Auto switch signal for SECAM
07h 40h // insert 656 ancillary header for raw data
11h 01h // AVID start pixel MSB, (01h in NTSC)
12h 04h // AVID start pixel LSB, (00h in NTSC)
13h 01h // AVID stop pixel MSB, (01h in NTSC)
14h 00h // AVID stop pixel LSB, (00h in NTSC)
I have tried to figure out what makes different between NTSC and PAL Setting during but failed.
If you have any suggestion or advice, please don't hesitate to reply me!
Regards,
Sam
