LAS VEGAS (AP) -- Postponing the turnoff of analog TV broadcasts beyond the scheduled date, Feb. 17, could confuse consumers, the chairman of the Federal Communications Commission warned Saturday.

President-elect Barack Obama's transition team on Thursday asked Congress to delay the shut-off. The main reason the team cited was that the Commerce Department earlier in the week ran out of money for the coupons that subsidize the cost of the converter boxes which allow older analog TVs to receive digital signals.

In an interview at the International Consumer Electronics Show here, FCC chairman Kevin Martin said it's important to make sure that the converter box subsidy program gets back on track, but that doesn't mean delaying the analog turnoff is necessary.

"There are options they can do without having to delay to get coupons flowing immediately," Martin said. Congress could give the program additional funding, or eliminate the 90-day expiration deadline on the coupons, he said.

"I'm concerned about a delay in the sense that if you can solve that issue other ways, a delay has actually the potential to confuse consumers," Martin said. "All of our messaging has been about Feb. 17 - not just ours - the industry's."

The Feb. 17 date has been widely advertised by local TV stations.

The date of the transition and the terms of the coupon program were set by Congress. The FCC, as the broadcast regulator, has an important role in administering the transition.
