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.
PoornimaSubramani Please reply.
what is specifications(resolution) of the camera ADZS-BF707 and also programme for video capturing
I'm not using ADZS-BF707 . I'm interfacing ADV7280A with FPGA and FPGA gives output to ADV7393. It is PAL 652i format. Is there any settings in ADV7280A to make sure it capture all incoming frames irrespective of video input signal voltage level (timing of video signal is verified and is matching with PAL 625i standard)?
ok,fne can we get that drive for ADV7280A?
drive for ADV7280A? ??
Could you also try recreating the issue on an ADV7280A evaluation board. If you do not have one you can contact your local Analog Device's sales office to have one shipped to you.
If you didn't observe the delay in our evaluation board, then crosscheck your schematic .
