Video signal identification about TW9992
I'm currently testing TW9992.I'd like to know how to handle the STANDARD SELECTION of 0x1c.Is "current standard invoked" a value that always changes when the state changes?I thought that N/A would be selected when I stopped the video input, but it kept the ...

Does TW9992 give acitve video data as directly RGB565/YUV422 or within ITU-R.BT656 format
... our needs. However, as I mentioned above, because of the struggle for some time with ADV7280-m, I would like to be exact sure that TW9992 suits for us. Does TW9992 give video data output the same format as OVP5640 camera does over MIPI bus? OVP5640 can give it directly ...
