Digital subchannels

The station's digital channel is multiplexed:

Channel	Video	Aspect	Callsign	Programming
21.1	1080i	16:9	XHTIT	Main XHTIT-TDT programming / Azteca 7 HD
21.2			XHTIT-2	a+ HD

Analog to digital conversion

Due to the Mexican analog-to-digital conversion mandate, XHTIT-TV shut down its analog signal on May 28, 2013, and then again on July 18, 2013. Tijuana was the first Mexican city where the analog to digital conversion took place.

XHTIT retained its virtual channel of 21 after October 2016 because channel 7 would create a channel conflict with KABC-TV over portions of San Diego County.
