variable-sized vectors can't be processed

Hi,

two frame based vectors of different lengths are connected to a multiport selector, after which an Integer to Bit Converter block shall do the conversion.

The problem is, the Integer to Bit Converter block doesn't accept variable-sized data. Are there any workaround to deal with it?

I think maybe one method helps: convert these two vectors into separate scalars and the variable-sized structure is destroyed, but I really need this structure.

Thank you Senmeis
