The ADV7842 used in our design and the register 0x12 of SDP map is set to the value 0x05.So, the 3D comb filter is enabled.However, the video the ADV7842 decoded is no difference with the video when the 3D comb filter is disabled. What's the effection of 3D comb filter? Is it necessary to be enabled ? What's the situation when it should be enabled ?
Can you help me !
Thank you !
