I wrote as I was able to do (!) ...
so when read what You asks 'bout "system of banners" I tried to translate an uderstandible one using google ...
... and that @sshol@ returned to me the same sentence !!!!
So ...I'll try :
with "system of banners" I intended to indicate the ones You've posted above,
but I think the mistake is with the syntax of the sentence and the meaning of "system", which perhaps, in the two languages has many different meanings !!
You 'll see that google translator will probably cause some damned diplomatic incident !!!!! !)
