TVP5146 has 2 vertical line in the frame

Hello All,

The mode setting is square sampling, PAL-B,D,G,H,I, (768*576). 

The registers setting as follow:

reg address: 00, val: 0C
reg address: 01, val: 0F
reg address: 02, val: 02
reg address: 03, val: 00
reg address: 04, val: 02
reg address: 05, val: 10
reg address: 06, val: 00
reg address: 07, val: 00
reg address: 08, val: 02
reg address: 16, val: 67
reg address: 17, val: 00
reg address: 18, val: B8
reg address: 19, val: 02
reg address: 32, val: 00
reg address: 33, val: C0
reg address: 34, val: 11
reg address: 35, val: EE
reg address: 36, val: AF
reg address: 37, val: FF
reg address: 38, val: FF
reg address: 39, val: 01
reg address: 74, val: 00

I got frames of size 768x576(it should be), but there are two verticle lines at the right part, how to fix it?

I change the AVID setting ,and found the vitical line also change the position, or maybe the vertical line disappear, but it has a duplicate part at the right.

  • Are you using embedded syncs or discrete syncs.

    I checked the YUV data file and it looks like embedded syncs are being included in the data (0xff, 0x00, 0x00).

    Make sure you are using the correct format for your target processor (embedded syncs or discrete syncs).

    BR,
