Dear Björn,

how does it work with a line camera? Can meta data be evaluated and stored in each line at each VA along the VA Chain?

Best regards, Stefan

Dear Björn,

assume an VA chain, going from Line Camera aquisition to VA1, follwed by VA2 , VA 3 and so on to VA n , then transfer from VA n to PC Memory.

Assume some of the VA produce meta information like Timestamp, ID, other generate Peak positions, other generate Minimum and Maximum Values and more and so on.

How can these meta information be handled in a way, that hey are treated as sideband information and not as picture information?

In the case meta information is treated as picture information, it will be affected by a VA and possibly not conserved and will not reach end of VA Chain.

So I understand that there is no concept in VA to handle sideband data.

As far as I understand is the timestamp not in the sideband but in the line of pixels itself. If i would apply an fft-VA on the line, the timestamp will be lost and I would get wrong fft output. Information is not in the sideband. Right?

We need to transfer meta informations ( like ID, Timestamp, Encoder values, etc. ) synchrounuous along the VA working chain. How to implement that?
