Hello,
I'm using TI ADC TVP5146M2 and I discover some issues:
1- Some vertical bar color appear behind the videos with a frequency around 2.3 Mhz.
the picture of this issue:
2- In RGB mode, the original colors are not restitutes correctly and depend on the video source. For example a DVD player can be use correctly in CVBS mode but don't have good color in RGB. Déactivate the AGC in AFE control register solve the problem in RGB. Is it the good process to do this or modify another register can be a better idea?
