Tvp5158 problems

The TVP5158 line-interleaved mode was specifically developed for use with the DM6446 and DM6467.

We've never tried to use any other mode with the DM6446 and DM6467.

To use the non-interleaved mode with the DM6446 and DM6467, bit 7 of I2C register B1h must be set to 1 (i.e. line-locked clock mode).  The line-locked clock mode is only supported on Port A.

Also, make sure you're using the latest patch.

Hi

          I have used the lastest patch “TVP5158_v020302” and set the bit7 of B1h register, but the problem still exist as usual.

          If you capture the video and look back it through the composite output, you can not see the phenomenon. We are capturing the video and transmitting the data to server which are  running in PC, so per frame can be seen very clearly. 

          How to solve the probleam, please help me!

  From the pictures,i only  see the lines in the moving video,so have you enable DM's smooth function? This is related with de-interlace.

If you can see the lines even in the static video,maybe is caused by line lost.

You are right, the lines only appear in the moving video.

 I'm not sure whether I have enable DM's smooth function, for I don't kown what it is. Can you tell me what is DM's smooth function and how to enable or disable it?

Thanks.

Please post the question in Davinc forum.
