This question might be primitive and common among HDMI Rx, but could you please explain the foudamental function/behaviour of the "avcode_insert_en" bit?


Back end processor received diffrent color bar data depending on the bit control.

Processor received data                  ADV748x setting

0xFEFEFE,0x010101        { 0xE0, 0x03, 0x86 }

0xFFFFFF,0x000000        { 0xE0, 0x03, 0x06 }  


I've checked this thread.

AVCODE_INSERT_EN will cause code 0x00 to change to 0x01 and 0xFF code to change to 0xFE.


Lastly just confirmation, is this bit control not affected on video deta transmission utself(i.e mipi)?
