Hello,
I am having some difficulties with the TVP5150AM1 and PAL-M input video. The resulting digital video output from TVP5150AM1 shows some serious anomalies on sharp transitions of the pictures. I am attaching some screenshots to help illustrate the problem. I am currently using the TVP5150A_v049002 patch (it was the only one that correctly recognized the PAL-M color setting).
Here is the input reference video:
And here are the waveforms for lines 142 and 143 of the input reference video (this is where the transition between colorbars and sweep occurs):
Everything looks good as it should. Now these are the resulting lines of the digital video encoded by the TVP5150AM1:
Line 142:
Line 143:
Line 144:
Line 145:
As you can see, there are some serious interference happening in this transition and only by line 145 the output is ok. This results in a low quality and distorted image.
I'm not sure why this is happening and what could be done to improve the results. I've already tried changing most of the register settings with no luck until now.
Can anyone help me?
Thank you!
Kind regards.
