TV companies are considering taking action after the transmission went down during a storm in the Euro 2008 semi-final between Germany and Turkey.
The transmission of live pictures to countries around the world failed three times during Germany's 3-2 victory.
Alexandre Fourtoy of Uefa said several events, including the extreme weather, had coincided to produce the blackout.
The BBC, one of many broadcasters to lose pictures during the match, is yet to decide whether to take action.
Uefa has switched to a different system for Thursday's semi-final.
The freak storm in Vienna on Wednesday saw lightning, heavy rain and winds of up to 87 mph, causing three power cuts.
Fourtoy, chief executive officer of Uefa Media Technologies, said: "It's a purely technical issue that we deeply regret, which (was due to) the coincidence of a lot of events including the weather which was pretty exceptional.
