What is "xhuaa-tdt"

XHUAA-TDT, virtual channel 57 ( UHF digital channel 22), is a television station located in Tijuana, Baja California, Mexico, whose over-the-air signal also covers the San Diego, California area across the international border in the United States. The station is owned by the Grupo Televisa; it is an affiliate of El Canal de las Estrellas. XHUAA began broadcasting in digital on UHF 22 in early 2006 making it the second station in Tijuana (and at the time one of very few in Mexico) to have a digital signal (sister station XETV was the first).

XHUAA signed on in 1990; its original concessionaire was Radiotelevisora de La Rumorosa, S.A. de C.V.
