DirecTV Inc. said Wednesday that, this spring, it will begin broadcasting local channels in high definition in 24 additional cities, including Salt Lake City.

The company will offer HD programing from the primary broadcast networks — ABC, CBS, Fox and NBC.

Customers with the appropriate DirecTV HD receiving equipment who subscribe to a programming package that includes local channels will receive both the standard and HD signals at no extra monthly charge.

The move will bring DirecTV local HD program to 58 percent of the country's television homes. The company offers standard-definition local channels in 141 markets, covering nearly 94 percent of TV households.
