I'm using an ADV212 in JDATA mode to compress PAL video and transfer it in a 8Mbps link.
Delay is the most important limitation in my design. I know ADV212 has 1.5 field delay and I buffer one field in transmitter(20 ms delay) an a frame in receiver(40 ms delay), therefor maximum delay should be 2*30+20+40=120 ms, but I'm experiencing 400ms delay which is not acceptable.
It gets worse when I decrease "Target Size". For a 4KB Field Packet Size, delay is three seconds!!
I have read from How to use ADV202 there is a 500KB internal Storage. Is there some sort of que in there that affects delay?
Is CODE FIFO threshold affects?
