I have been looking at it, but I can not find anything at all about this.
The only thing I can say is that DV in general uses 1 for reserved or not
available data in the headers or AAUX packets.
Also all-1 gives longer VLC code words, so padding with 1 might make it easier
to detect a damaged EOB marker, though that is quite questionable.
