TDA3MV: The PAL vedio is not right which had half dotted line

Hi,

As explained in the above thread, can you try slightly increasing start position the register? It should go away with this change.

Thank you for reply.

I tried increasing it little by little, but there was no change.

Hi David,

Are you sure that these artifacts are not coming from input image?

Hi,

Can you try changing value of value of variable aVidStrStpY in the file.

vision_sdk\ti_components\drivers\pdk_xx_xx_xx_x\packages\ti\drv\vps\src\vpslib\hal\src\vpshal_dssSdVenc.c, in such a way that total number of lines remain 576?

For example if you increase start-Y by 2 lines, ie instead of 0x2E, set it to 0x30, then end_y should also be changed to 0x270.

can you try it?

#1 Are you sure that these artifacts are not coming from input image? 

-> yes, because HDMI output is normal.

#2 Can you try changing value of value of variable aVidStrStpY in the file.

-> I tried the solution, but the problem was not solved.  The dotted line remains the same, only the image descends from the first line.

Is any other solution?
