EAST RUTHERFORD, N.J. — How do you keep football fans as regular visitors to stadiums when the television coverage of every play is so good?

For the Giants and the Jets, the answer, perhaps surprisingly, is more and better video than people can get at home. This season, the New Meadowlands Stadium will offer fans free smart-phone applications that they can glance at to see video replays, updated statistics and live video from other games — and that will work only inside a stadium.

Because the TV's better there.
