TVP5150 Horizontal Offsetting Problem

Other Parts Discussed in Thread: TVP5150AM1, TVP5150, TVP7002

I'm currently working in a project with arm9 and the TVP5150AM1, and i having a very strange issue, when i connect and disconnect the video signal cable from TVP5150 CVBS input, occasionally the video offsets horizontally, i observed that some noise on input can cause the same issue.

I'm using NTSC video signal:

Registers:

0x03 - > 0x2F
0x04 -> 0xF8
0x0D -> 0x00
0x0F -> 0x0A

Any Thoughts on helping me with this issue?

Luiz,

No,the issue is not caused by TVP5150AM1,not the noise. It caused by your ARM9's sync module.

At last post,please reset your video input port to restart capture BT.656 when your ARM detects signal present from non-present.
