University of North Carolina Television, known on-air as UNC-TV, is a statewide public television network in the U.S. state of North Carolina. It is operated by the University of North Carolina, with studios located at the UNC Center for Public Television at Research Triangle Park. The network includes all PBS member stations licensed within North Carolina except for WTVI in Charlotte, which is a community licensee.

It also formerly operated four digital channels: UNC-KD (children's programs), UNC-HD (high-definition programming), UNC-NC (North Carolina public affairs and original local productions) and UNC-ED (educational television). Consumers with Time Warner Cable, the largest cable provider in the state, are the only ones capable of receiving all of these digital subchannels. Time Warner has a direct-fiber optic connection to the broadcast facilities of UNC-TV.

On September 25th, 2008, UNC-TV commenced a revised lineup of three digital subchannels via over-the-air broadcast television: UNC-TV (the main channel now operating as a full-time HD service), UNC-KD in SD, and UNC-NC in SD. [1]

Directv added UNC-TV HD and UNC-KD SD to its local broadcast packages on June 30, 2009. (mpeg4 equipment required)

Overview

WUNC-TV in Chapel Hill, the network's flagship station, signed on January 8, 1955 as the first educational television station south of Washington, D.C.. In the next 12 years, three more stations signed on and a system of translators in the mountains allowed the network to reach across the entire state. The network's youngest station, WUNU in Lumberton, signed on in 1996. The network was known on-air as North Carolina Public Television (identified in North Carolina editions of TV Guide as CPT, an abbreviated form of "University of North Carolina Center for Public Television") from the 1970s through the mid-1990s, when it began calling itself University of North Carolina Television. It adopted the shorter name of UNC-TV later in the 1990s.

The network creates many programs of local interest, including the newsmagazine North Carolina Now, the interview series North Carolina People (hosted by former UNC president William Friday), Carolina Outdoor Journal, Exploring North Carolina, North Carolina Bookwatch with D.G. Martin, and special programs about the state's history and culture (often seen during the network's annual pledge drive). It also creates two programs for national distribution (The Woodwright's Shop and Lap Quilting with Georgia Bonesteel). In addition to PBS programs, the station also runs British comedies on Saturday nights and EastEnders on Sunday nights.

Stations

UNC-TV operates eleven transmitters that broadcast across the entire state as well as into parts of Virginia, Tennessee and South Carolina.

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

Notes:

  • 1. WUND-TV used the callsign WUNB-TV from its 1965 sign-on to 1967.
  • 2. WUND-TV was originally licensed to Columbia; the license was moved to Edenton in 2005. ([1])
  • 3. Five stations in the Wilmington DMA began transmitting solely in digital starting September 8, 2008. WUNJ-TV opted to continue analog broadcasts until the national switchover on June 12, 2009.
  • 4. WUNW will operate as a digital-only station with a target date for commencement of operations tenatively scheduled for February 2010. [2][3]

Digital television

UNC-TV's current over-the-air digital configuration, which is multiplexed among 3 subchannels, was introduced on September 25th, 2008.

Sub-channel Programming
xx.1 main UNC-TV/PBS programming in HD
xx.2 UNC-KD (children's programming)
xx.3 UNC-EX (The Explorer Channel: travel, culture, science,
and outoor adventure (as of 11-1-09))[4]

Cable providers with a direct fiber optic link to UNC-TV also carry UNC-MX (formerly UNC-ED) as part of their digital tiers. UNC-MX is a mix of how-to and public affairs programs, together with encores of programs from the primary UNC-TV channel. Cable systems which rely on off-air reception for broadcast stations are limited to the three-channel lineup.

The network's multiplexed digital signals before September 25, 2008 were:

Sub-channel Programming
xx.1 main UNC-TV/PBS programming
xx.2 UNC-HD (PBS programs in HD)
xx.3 UNC-KD (children's programming)
xx.4 UNC-ED (educational programming)
xx.5 UNC-NC (North Carolina-centric programming)

Due to bandwidth limitations, the over-the-air version of UNC-HD was only available between 8-11pm, during which UNC-ED and UNC-NC were off the air. Cable systems with a direct digital link to UNC-TV facilities broadcast all five channels on a 24 hour schedule.

Analog-to-digital conversion

After the analog television shutdown and digital conversion on June 12, 2009:[5]

  • WUNC-TV moved its digital broadcasts from channel 59 to channel 25;[6]
  • WUNE-TV, WUNM-TV, WUNP-TV, and WUNU moved their digital broadcasts back to their respective analog channel numbers (they were at 54, 18, 39, and 25, respectively);[7][8][9][10]
  • WUND-TV, WUNF-TV, WUNG-TV, WUNJ-TV, WUNK-TV, and WUNL-TV remained on their respective, pre-transition channel numbers (20, 25, 44, 29, 23, and 32).[11][12][13][14][15][16]

UNC-TV opted not to join other broadcasters in the Wilmington market in the decision to switch to digital-only broadcasts on September 8, 2008, nine months ahead of the national deadline.[17] Following that date, WUNJ-TV became Wilmington's only full-power analog signal until the national digital switchover in June 2009.

Through the use of PSIP, digital television receivers are displaying virtual channels for each UNC-TV station corresponding to their previous analog channel numbers.

Translators

UNC-TV operates a number of translators across the mountains of western North Carolina. These translators serve as low-power, limited-area repeaters for WUNF and WUNE, mainly targeting towns in deep mountain valleys where the parent signal is blocked by the surrounding terrain.

Cable and satellite

UNC TV is available on cable television services throughout the state. It is also available in the South Hampton Roads area of Virginia (Norfolk and Virginia Beach) through Cox Communications and in the Greenville, South Carolina area through Charter Communications.

On DirecTV and Dish Network, WUNC-TV, WUND-TV, WUNF-TV, WUNG-TV, WUNJ-TV, WUNL-TV and WUNK-TV are available on the Triangle, Hampton Roads, Greenville/Spartanburg/Asheville, Charlotte, Triad, Wilmington and New Bern/Greenville/Washington local feeds, respectively.

The station carried on cable systems is not always the closest station. For example, Time Warner Cable (formerly Adelphia) in Laurinburg carries WUNJ of Wilmington, despite WUNU being closer in Lumberton.
