In the datasheet of the " TDA935X/6X/8X PS/N2 series TV signal processor-Teletext decoder with embedded µ-Controller " says:

• Source selection between ‘internal’ CVBS and external CVBS or Y/C signals

Datasheet: https://www.alldatasheet.com/datasheet-pdf/download/1770425/PHILIPS/TDA9381.html

Can anybody tell me how to proceed to chose between CVBS and Y/C signal?

 

Hi,
Just a thought, could it be done via the remote control unit?

 

I tried via remote with the chk1 options, nothing worked. I'm able to access the memory via remote, but Im too scared to alter any value.
