local 'drop in' adverts run on top of (in place of) the
national feed; additionally one can buy differnt drop in's for
different customers, as is a commonly pitched 'advanage' of
placing adverts through a Cable operator.
Obviously clock synchronization down to the sub second is not
attained as to 'cuts' between content feeds; when this
happens, the 'blips' appear
You can see this kind of 'missed switching timing' a lot on
CNBC and so forth
