Reducing pipeline delay

[Steve_Bz]

Hi guys,

I have a data capture card which I wish to be real-time.  However it has a delay of about .5 sec, which is too much.  0.1 secs would be better.  It needs to be imperceptible.  I'm not sure which delays come from the card, which from the computer and which come from programmed buffer delays in the pipeline.

Is there a command or value I can set (like buffering = '0')  or something which would allow me to minimise any delay in the pipeline?

Or any other ideas of sources of delays and things I could do to minimise them?

Thanks

Steve

You haven't told us anything about how you capture from the card, not even wheter it is audio or video or both.
