Digital Television
UNC-TV's current over-the-air digital configuration, which is multiplexed among 3 subchannels, was introduced on September 25, 2008. Prior to November 1, 2009, the third subchannel was named UNC-NC.
This configuration is used for WUNC, WUND, WUNF, WUNG, WUNJ, WUNK, WUNL, and WUNU:
| Channel | PSIP Short Name | Programming |
|---|---|---|
| xx.1 | UNC-TV | Main UNC-TV programming / PBS |
| xx.2 | UNC-KD | PBS Kids |
| xx.3 | UNC-EX | The Explorer Channel |
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 media 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.
| Channel | PSIP Short Name | Programming |
|---|---|---|
| xx.1 | UNC-EX | The Explorer Channel |
| xx.2 | UNC-TV | Main UNC-TV programming / PBS |
| xx.3 | UNC-KD | PBS Kids |
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 state network's multiplexed digital signals before September 25, 2008 were:
| Channel | PSIP Short Name | Programming |
|---|---|---|
| xx.1 | UNC-TV | Main UNC-TV programming / PBS |
| xx.2 | UNC-HD | Main UNC-TV programming / PBS HD |
| xx.3 | UNC-KD | PBS Kids |
| 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.

Famous quotes containing the word television:
“So by all means let’s have a television show quick and long, even if the commercial has to be delivered by a man in a white coat with a stethoscope hanging around his neck, selling ergot pills. After all the public is entitled to what it wants, isn’t it? The Romans knew that and even they lasted four hundred years after they started to putrefy.”
—Raymond Chandler (1888–1959)
