DirecTV will expand its high-definition of local TV stations with the addition of 24 more markets this spring, the company announced.

Beginning in April, DirecTV will begin offering HD programming from the four primary broadcast networks — ABC, CBS, Fox and NBC. Customers with 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 expansion will bring the number of local HD markets offered by DirecTV to 36 markets across the United States.
