WXXI-TV is a Public Broadcasting Service (PBS) member television station licensed to Rochester, New York, United States. It broadcasts a high definition digital signal on UHF channel 16 (or virtual channel 21 via PSIP) from a transmitter on Pinnacle Hill on the border between Rochester and Brighton. Owned by the WXXI Public Broadcasting Council, it is a sister station to National Public Radio (NPR) members WXXI (AM 1370) and WXXI-FM (91.5). The three outlets share studios on State Street near downtown Rochester.

Digital television[edit]

Digital channels[edit]

WXXI-TV entered the digital era in September 2003 when it signed on with Rochester's first full-power digital television signal.

The station's digital signal is multiplexed:

Channel Video Aspect PSIP Short Name Programming[1]
21.1 1080i 16:9 WXXI-HD Main WXXI-TV programming / PBS
21.2 480i 4:3 WXXI-W World
21.3 WXXI-C Create
21.4 WXXI-K PBS Kids
16.7 WXXI-FM Classical 91.5
(WXXI Readout Radio is on the subchannel's SAP)

Channel 21-4, now PBS Kids since February 1, 2016, was originally a digital standard definition simulcast of WXXI-TV's analog signal but is not currently transmitting, as 21-1 is identical.

Analog-to-digital conversion[edit]

WXXI-TV discontinued regular programming on its analog signal, over UHF channel 21, on June 12, 2009, the official date in 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.[2] 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,[3] WXXI-TV kept its analog signal on the air until July 10 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.[4]

Programming[edit]

National productions[edit]

WXXI-TV's national public television productions include A Warrior in Two Worlds, Echoes from the Ancients, Out of the Fire, Albert Paley: Man of Steel and Flight to Freedom. WXXI-TV also produced Assignment: The World, a weekly current-events program for schools, which aired on approximately 100 public television stations nationwide, and was the nation's longest-running instructional television program. Due to funding cuts, it was canceled and its last episode aired on May 23, 2013.
