we use the ADV7391 with BT656 input to standard PAL CVBS output 625i, SD mode 0.
For special purpose we need to put data into the input stream during VBI in video line 12 + 13 and 324 + 325. The input stream comes out of a fpga, so it ist possible to manipulate the stream.
My question is, is the video encoder able to output this data in the CVBS signal and how are the correct settings for the register?
Thank you for any suggestions
