DirecTV, the satellite TV provider owned by No. 2 U.S. wireless carrier AT&T Inc., said all channels have been restored after experiencing loss of audio and video for at least two hours on Tuesday.

"All channels have been restored. We apologize for the inconvenience," AT&T spokesman Eric Ryan said in a statement.

AT&T bought DirecTV for $48.5 billion last year, making it the world's No. 1 pay-TV operator with 45 million video subscribers, including Mexico and Latin America, at the end of 2015.
