We're still missing our Sunday dose of NFL action, but as the offseason continues the league is once again looking into using high definition footage for instant replay. League meetings start tomorrow, and one of the changes being considered by the rules committee is a proposal to make instant replay a permanent part of the game, as it is currently a temporary rule, due to expire in two years. The leagues owners will only consider switching the instant replay equipment to HDTV if they are sure its here to stay, otherwise the ref could be stuck with a poor 480i feed for at least another year. Last year, the league looked at how NASCAR handles its HD, and that sport even has high def in-car cameras now. That instant replay should feature the highest quality available goes without saying, now we're looking forward to HD helmet cams.
