Frequently Asked Question

How do I know when the ADV202/212 has finished compressing a field/frame/image?

In encode mode the LCODE signal on the SCOMM4 pin is used to indicate when the last word of the CODE FIFO is being read out.

SCOMM4/ LCODE is enabled by default and will assert [high] after the JPEG2000 EOC marker [0xFFD9]. For more detail on LCODE timing refer to:
