How to use the ADV202/212 with multiple-camera input
If video sources are switched while the ADV202/212 is processing a field/frame the present field/frame will be flushed out of memory and the ADV202/ADV212 will wait for the next available valid synchronisation signal.
This will be the next in-active Vsync edge if HVF are used, or the next valid EAV/SAV code.
The ADV202/212 will not be able to identify which source has been used although it will update the image index value in the ADV2x2 header for every consecutive field/frame received. The ADV2x2 header is a 16-byte header that is inserted at the start of every field/frame/image before the JPEG2000 headers.
