Channel 21.4, now PBS Kids since February 1, 2016, was originally a digital standard definition simulcast of WXXI-TV's analog signal.

Analog-to-digital conversion

WXXI-TV discontinued regular programming on its analog signal, over UHF channel 21, on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital signal remained on its pre-transition UHF channel 16. [3] Through the use of PSIP, digital television receivers display the station's virtual channel as its former UHF analog channel 21.

As part of the SAFER Act, [4] WXXI-TV kept its analog signal on the air until July 10, 2009, to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters. WXXI-TV had been awarded a $202,498 federal contract for an outreach initiative to help Rochester's over-the-air viewers prepare for the digital transition. [5]
