ADV7280A adding delay to decoded video signals


I'm using ADV7280A for decoding PAL video . When i'm connecting camera (camera A) output directly to monitor it gives no delay but at the same time when it is connected to ADV7280A i'm observing delay (decoded output connected to ADV7393 and then to same monitor). But at the same time a different camera (camera B) when connected to same ADV7280A gives no delay. Please clarify.

Here are few things i observed. The frame rate given by ADV7280A (decoded output) when connected with camera A was less compared with camera B. But both cameras don't had delay when connected with external monitor directly.

Please reply.
