Hawk-Eye is already used in tennis and cricket. The English company was bought by Sony Corp., a World Cup sponsor, during the testing process.

GoalRef uses magnetic sensors in the goalposts to track an "intelligent" ball, made by Danish company Select. Both systems relay information within one second to the referee's wristwatch.

He changed his stance after seeing match officials miss Lampard's shot bounce off the crossbar and land fully over the goal line in Bloemfontein. England would have leveled at 2-2 before halftime but lost 4-1 in the second round. Blatter said two days later that FIFA should reopen the debate, although video replay remains off limits for judgment calls. (AP) AH AH 02201031 NNNN
