No, it can't have been done with projectors because when the Canadian
anthem was playing and there was a great big Canadian flag covering the
entire ice surface, I didn't see the Tampa Bay Lightning logo that's
clearly visible in the middle of the arena ice when the flags weren't
So, I can see how a projector could produce a Canadian or American flag
onto the entire ice surface, but how does ADDING light remove the logo
and the 4 face off red dots and circles?
The only thing that makes sense to me is that the flag was put into the
TV signal so that the people in the arena couldn't see it, and the
people at home could see nothing but the flag.
If those flags were done by projecting light onto the ice, the Tampa Bay
Lightning logo would still be visible to everyone in the arena and
everyone watching at home. And, in the case of the Canadian flag, that
would muck up the appearance of the Canadian flag by messing up it's
central red maple leaf. And I recall clearly that it was a normal
Canadian flag, with no hockey team logo messing up the red maple leaf,
and no face off dots and circles messing up the red bands on either side
of the maple leaf.
