XHUAA-TDT, virtual channel 57 (UHF digital channel 22), is a Las Estrellas owned-and-operated 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. 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.

By then-current Mexican law, XHUAA was suggested to start broadcasting digital television by January 1, 2010, although this station was allowed at its discretion to start broadcasting DTV before law required it to, and XHUAA-TDT had signed on in 2006. The original assignment was channel 20, but the chosen channel caused issues to land mobile services in Los Angeles, prompting the FCC in the United States to request a channel change.
Due to the conversion mandate, XHUAA-TV shut down its analog signal on May 28, 2013 and again on July 18, 2013, due to issues relating to elections. Tijuana was the first Mexican city to start the analog to digital conversion in Mexico.
