Dish Network Corp.'s new commercial-skipping technology "Auto Hop" is an attack on the broadcasters' eco-system, NBC Broadcasting Chairman Ted Harbert said.

The Auto Hop automatically removes ads or commercials from recorded prime-time programs from the four big broadcast networks, viz. ABC, CBS, NBC and Fox. Broadcasters are concerned that such devices could hurt their advertisement revenues very hard.

Announcing NBC's prime-time schedule for 2012-13 at the company's conference call, Harbert said, "I think this is an attack on our eco-system. I'm not for it."

However, he declined to confirm whether NBC or its parent firm Comcast Corp. had any plans to take a legal action against Dish Network for its controversial technology.

He only said he would issue a detailed message to Dish Network and advertisers on Monday at Radio City Music Hall. The broadcaster will use the Monday event to share its fall advertisement schedule with advertisers.

Users of the Dish's PrimeTime Anytime feature can make use of the Auto Hop to delete commercials, provided the programs are watched a day after their original airing.
