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:

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.

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:

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.
