История

Wunc-TV в Чапел-Хилл государственной сети , флагманской станции , впервые подписанной в эфире 8 января 1955 года, в качестве второй некоммерческой образовательной телевизионной станции, расположенной к югу от Вашингтона, округ Колумбия, -через один день после Чеха , Алабама - wciq-- Телевидение ​В течение следующих двенадцати лет еще четыре спутниковые станции подписано . Wund-TV в Эдентоне (первоначально Wunb-TV, лицензированный в Колумбии ) был первым из этих спутников, которые дебютировали 10 сентября 1965 года, за которым последовали запуск Wune-TV в Линвилле , Wunf-TV в Эшвилле и Wend-TV В Конкорде -все 11 сентября 1967 года и Wunj-TV в Уилмингтоне 4 июня 1971 года. Это было дополнено сетью станций переводчиков в Аппалачских горах , которые также позволили программированию сети достичь всего штата.

Logo under the "UNC-TV" brand, used from 1995 to January 11, 2021; the circular "hurricane" emblem had been used in some capacity since 1978.

Five additional satellites debuted afterward: WUNK-TV in Greenville in May 1972, WUNL-TV in Winston-Salem in February 1973, WUNM-TV in Jacksonville in November 1982, WUNP-TV in Roanoke Rapids in October 1986, and WUNU-TV in Lumberton in September 1996. The state network's youngest station, WUNW in Canton, signed on in July 2010 to replace a translator that had served the area since the 1980s. The state network was branded on-air as North Carolina Public Television from 1979 to the mid-1990s, when it rebranded itself as University of North Carolina Television. It simplified the brand name to UNC-TV later in the 1990s; it had previously used that brand for most of the 1970s. On January 12, 2021, in recognition of PBS' growing online content delivery, the state network rebranded itself as "PBS North Carolina," while continuing to acknowledge its ties to the university system as being "Powered by the UNC System".

Programming

The state network produces many programs of local interest, including the weeknightly public affairs program North Carolina Now, Our State, Carolina Outdoor Journal, Exploring North Carolina, North Carolina Bookwatch with D. G. Martin, and special programs about the state's history and culture. It also produces The Woodwright's Shop, Growing a Greener World, The Zula Patrol, and Song of the Mountains for national distribution. In addition to PBS and American Public Television programs and local productions, the station also runs programming from the United Kingdom, including "Britcoms" on Saturday evenings and the soap opera EastEnders on Sunday evenings. In the 1990s, UNC-TV introduced "Read-A-Roo," a kangaroo used as the mascot for the network's children's programming. PBS North Carolina airs its own public affairs programming on Sunday mornings.

Stations

PBS NC operates twelve stations that relay its programming across the entire state as well as into portions of Virginia, Tennessee, Georgia, and South Carolina.

Each station's callsign consists of "UN" for the University of North Carolina, followed by a letter assigned sequentially in the order in which it was activated, except for the first station.

Subchannels

PBS NC's current over-the-air digital configuration, which is multiplexed among three subchannels, was introduced on September 25, 2008. On that date, UNC-TV revised its subchannel lineup on its stations, reducing the number of channels to three: UNC-TV (the main channel of each station, which now carries high definition programming), and the standard definition-only services UNC-KD and UNC-EX ("The Explorer Channel"). UNC-TV HD and UNC-EX are also available to DirecTV customers with MPEG4-compatible receivers. Prior to February 1, 2016, Time Warner Cable customers also received UNC-MX (described as "an eclectic mix of programming for adults") in standard definition; the North Carolina Channel has since replaced UNC-MX on Time Warner Cable systems. Prior to November 1, 2009, the third subchannel was named UNC-NC.

This configuration is used for WUND, WUNF, WUNG, WUNJ, WUNK, and WUNU:

PBS NC multiplex

Channel	Res.	Aspect	Short name	Programming
xx.1	1080i	16:9	PBS NC	PBS
xx.2	480i		ROOTLE	PBS Kids Channel
xx.3			UNC-EX	The Explorer Channel
xx.4			NCCHL	The North Carolina Channel

This configuration is used for WUNC and WUNL:

Subchannels of WUNC-TV/WUNL-TV and WRAY-TV/WLXI

License	Channel	Res.	Aspect	Short name	Programming
WUNC-TV/WUNL-TV	4.1/26.1	1080i	16:9	PBS NC	PBS
	4.2/26.2	480i		ROOTLE	PBS Kids Channel
	4.3/26.3			UNC-EX	The Explorer Channel
	4.4/26.4			NCCHL	The North Carolina Channel
WRAY-TV/WLXI	30.1/43.1	1080i		WRAY/WLXI	TCT

An alternate configuration is used for WUNE, WUNM, WUNP, and WUNW. The original purpose for this was to obtain must-carry status for UNC-KD since those are secondary stations in their respective markets. On June 15, 2010, UNC-KD switched subchannels with UNC-EX on the four stations previously mentioned, which transferred UNC-KD's must-carry status to UNC-EX.

Subscribers of Charter Spectrum, the major cable provider in the state, have direct-fiber optic versions of each of PBS North Carolina's networks rather than an antenna feed of their local station, as Spectrum forerunner company Time Warner Cable built out a direct connection to PBS NC's studios at the RTP, a connection inherited by Spectrum parent Charter Communications when it merged with Time Warner Cable in 2016.

Cable providers with a direct fiber optic link to UNC-TV (including Spectrum) formerly had exclusivity in carrying UNC-MX (formerly UNC-ED) on their digital tiers. UNC-MX featured a mix of how-to and public affairs programs, along with encore presentations of programs originally broadcast on main UNC-TV service. On February 1, 2016, UNC-MX was renamed UNC-NC "The North Carolina Channel" and was added over-the-air on DT-4, allowing full access to the service by over-the-air and non-Spectrum viewers. On July 2, 2016, UNC-KD was rebranded as ROOTLE.

Prior to September 25, 2008, UNC-TV formerly operated four digital channels: in addition to the main signal on the primary channel, the second digital subchannel of each station carried UNC-HD (which carried PBS and regional programming in high-definition), the third subchannel carried UNC-KD (which carried children's programs), the fourth subchannel carried UNC-ED (an educational television service) and the fifth subchannel carried UNC-NC (centering on North Carolina public affairs and original local productions). Due to bandwidth limitations at the time, the over-the-air feed of UNC-HD was only available between 8-11 p.m., during which UNC-ED and UNC-NC ceased transmission in the interim. Cable systems with a direct fiber link to UNC-TV facilities aired all five channels on a 24-hour schedule.

On April 16, 2018, WRAY-TV and WLXI were merged onto WUNC's spectrum, after parent company Tri-State Christian Television (TCT) sold the stations' individual bandwidth in the 2016 FCC incentive auction. WUNC is the only station in the 12-station network that has a channel sharing agreement.

Analog-to-digital conversion

UNC-TV's stations ended regular programming on their analog signals 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 channel allocations pre- and post-transition are as follows:

Call sign	Analog channel	Pre-transition digital channel	Post-transition digital channel	FCC Repack Plan (2017)
WUNC	4	59	25	20
WUND	2	20	20	29
WUNE	17	54	17	36
WUNF	33	25	25	20
WUNG	58	44	44	21
WUNJ	39	29	29	21
WUNK	25	23	23	25
WUNL	26	32	32	33
WUNM	19	18	19	28
WUNP	36	39	36	27
WUNU	31	25	31	30
WUNW	—	—	27	27

All channels retained their original numbering for display to viewers via PSIP.

UNC-TV opted not to join other broadcasters in the Wilmington market in an early switch to digital-only broadcasts on September 8, 2008, nine months ahead of the national transition deadline. Following that date, WUNJ-TV became only full-power station in Wilmington that continued to broadcast an analog signal until the national digital transition on June 12, 2009.

As part of the SAFER Act, WUND and WUNF kept its analog signal on the air until July 12 (for WUND) and June 26 (for WUNF) to inform viewers of the digital television transition through a loop of public service announcements from the National Association of Broadcasters.

ATSC 3.0

On March 22, 2021, WUNC-TV began broadcasting in ATSC 3.0, with a 1080p stream (virtual channel 4.11) on Capitol Broadcasting Company's host station WARZ-CD (now WNGT-CD). On June 29, 2021, WUNK-TV was converted to ATSC 3.0 with all sub-channels included. While a simulcast of WUNK-TV is shared on WUNM-TV, areas outside WUNM-TV are covered by other nearby network stations, thus the conversion did not result in any loss of over-the-air PBS service.

Translators

PBS NC operates 19 translators. Each translator is assigned to the license of a parent PBS NC full-power station, all of which simulcast the same network signal. Two directly repeat WUNC-TV, two directly repeat WUNE-TV, two directly repeat WUNG-TV, three directly repeat WUNL-TV, and 10 directly repeat WUNF-TV.

The 17 mountain-based translators serve as low-power, limited-area repeaters that bring the network's signal to towns in deep mountain valleys where the parent signal is blocked by the surrounding terrain. The translators of WUNC-TV act as digital replacement translators serving the few areas of the Triangle where WUNC-TV lost over-the-air coverage during the analog-digital conversion in 2009.

The following digital replacement translators rebroadcast WUNC-TV:

• Raleigh: WUNC-DRT
• Oxford: WUNC-DRT

The following translators rebroadcast WUNE-TV:

• Marion: W22FB-D
• Bat Cave: W29FE-D

The following translators rebroadcast WUNF-TV:

• Franklin (Wine Spring Bald): W19DB-D
• Andrews, etc.: W20EK-D
• Canton, etc.: W28EE-D
• Hayesville: W29DE-D
• Murphy: W31AN-D
• Franklin (Cowee Bald): W31DH-D
• Black Mountain: W33EH-D
• Highlands: W35CK-D
• Burnsville: W35CO-D

The following translators rebroadcast WUNG-TV:

• Tryon: W16DZ-D
• Jefferson: W30EF-D
• Spruce Pine: W31DI-D

The following translators rebroadcast WUNL-TV:

• Sparta: W15EF-D
• Boone: W27EK-D
• Zionville: W30CS-D

The licenses for translators in Bakersville (W42AX-D), Brevard (W19DD-D), Bryson City (W46AX-D), Cashiers (W42DF-D) and Cullowhee (W47DM-D) were surrendered to the Federal Communications Commission and cancelled on October 27, 2021. These were replaced with a distributed transmission system using the channel 27 frequency of WUNW.
