GPB Television broadcasts PBS programming and statewide programs produced specifically for the GPB network 24 hours a day on a network of nine full-power stations as well as numerous
low-power translator stations (especially in the state's mountainous northeastern counties). Certain programs broadcast by GPB Television (mainly those provided by PBS) feature a
Descriptive Video Service track that is audible over the
second audio program (SAP) channel of each station; GPB Radio feeds could previously be heard during times when DVS-transcribed programs were not airing, prior to the 2009
digital television transition. All stations within the GPB Television network act as
rebroadcasters,
simulcasting the network's programming at all times. GPB-produced programs include
Gardening in Georgia,
Georgia Backroads, ''Georgia's Business
, Georgia Outdoors
and Georgia Traveler'', as well as annual coverage of the
Georgia General Assembly when it is in
legislative session early in the year. Live coverage of the
football and
basketball championship games from the
Georgia High School Association is broadcast at the end of their respective seasons. GPB Television also operates four
digital subchannels that are carried on most of its stations:
GPB Knowledge debuted in September 2008, but officially launched on October 1 of that year. GPB Knowledge carries programming from the
World network during
prime time hours, and GPB
documentary and news programming (including
BBC World News) at other times. It replaced GPB Education, which is still available to schools statewide
on demand over the
Internet.
GPB Kids, launched in January 2009 as the second
digital subchannel of the GPBTV stations, replacing the
standard-definition feed (which mirrored each station's analog feed) of GPB's main channel. GPB Kids aired 24/7 with content from
PBS Kids. During December 2008, the subchannel carried only a static
station identification for all nine stations (including the GPB/
PBS Kids logo), and the
electronic program guide for the channel continued to show main channel information for the GPBTV stations. In March 2015, GPB Kids was replaced with
Create. In January 2017,
PBS Kids 24/7 was launched, being the fourth digital subchannel of the GPB TV stations.
Television stations Each of GPB's television stations identify themselves with two locations—usually, the smaller
community where the station is licensed by the
Federal Communications Commission (almost always the station's transmitter location) and the larger city that it serves. The exceptions are WVAN-TV and WJSP-TV, which are actually licensed in major Georgia cities: WVAN-TV is licensed to Savannah, while WJSP-TV is licensed to Columbus. However, in order to conform to the pattern, GPB lists the locations for the stations' transmitters as the second city. This rule only applies to the television stations, not to those on radio, which, except for two, bear only the city of license. The GPB television stations are:
Footnotes Broadcast translators GPB Television operates several low-power translator stations located in the hilly terrain of the
north Georgia mountains. These include:
Former translators The following translators were abandoned by GPB, which had their licenses (and in some cases, digital applications and permits) cancelled by the FCC, apparently at GPB's request, possibly due to the expense of running and upgrading them.
WUGA-TV On December 23, 2010, the
University of Georgia announced that it would enter into a programming partnership with GPB, which would provide all programming for the university-owned WNEG-TV (channel 32) in
Toccoa, with most of the content coming from its GPB Knowledge subchannel. The station filed with the FCC to convert WNEG's station license to
non-commercial status. The partnership between UGA and GPB was due to a reduction of advertising dollars, resulting from an economic downturn and the loss of WNEG's
CBS affiliation (the station had been with CBS since August 1995, receiving affiliation as a by-product of the CBS programming moving in the adjacent Atlanta market from
WAGA-TV [channel 5] to
WGCL-TV [channel 46] in December 1994). At 5:30 am on May 1, 2011, the station began carrying GPB Knowledge programming; the following day, its call letters were changed to WUGA-TV. UGA sold WUGA-TV to Marquee Broadcasting in 2015; at 12:01 am on July 1, 2015, the new owners dropped all GPB Knowledge programming, changed the station's call letters to
WGTA, and returned the station to commercial operation with programming from the
MeTV,
Heroes & Icons,
Decades, and
Movies! networks.
Digital television WGTV, WXGA-TV, and WVAN-TV were the first GPB stations to begin operating their own
digital television signals. The other six stations signed on their digital signals in July 2008. The ERP/HAAT figures listed within the table for those stations are based on those listed in the stations' individual FCC queries, though some of the stations were operating at low power, and only upgraded to full-power when the digital transition occurred.
Subchannels The digital signals of GPB's TV stations are
multiplexed: All nine stations carry the same programming from each of the four channels, but channel labels differ somewhat between the stations.
Analog-to-digital conversion The GPB Television stations shut down their analog signals on February 17, 2009, as part of the
federally mandated transition from analog to digital television (which Congress had moved the previous month to June 12). Each stations' post-transition digital allocations are as follows: • WABW-TV shut down its analog signal, over
UHF channel 14; the station's digital signal moved from its pre-transition
VHF channel 5 to channel 6, using
virtual channel 14. • WACS-TV shut down its analog signal, over UHF channel 25; the station's digital signal remained on its pre-transition VHF channel 8, using virtual channel 25. • WCES-TV shut down its analog signal, over UHF channel 20; the station's digital signal moved from its pre-transition VHF channel 2 to channel 6, using virtual channel 20. • WGTV shut down its analog signal, over VHF channel 8; the station's digital signal relocated from its pre-transition VHF channel 12 to channel 8. • WJSP-TV shut down its analog signal, over UHF channel 28; the station's digital signal remained on its pre-transition UHF channel 23, using virtual channel 28. The station was licensed to move its digital signal to VHF channel 5 effective April 5, 2019. • WMUM-TV shut down its analog signal, over UHF channel 29; the station's digital signal remained on its pre-transition VHF channel 7, using virtual channel 29. • WNGH-TV shut down its analog signal, over UHF channel 18; the station's digital signal remained on its pre-transition UHF channel 33, using virtual channel 18. • WVAN-TV shut down its analog signal, over VHF channel 9; the station's digital signal relocated from its pre-transition VHF channel 13 to channel 9. • WXGA-TV shut down its analog signal, over VHF channel 8; the station's digital signal relocated from its pre-transition VHF channel 9 to channel 8. GPB has placed most of its stations on VHF due to the lower
effective radiated power requirements (20 or 32 kW instead of 1000 kW), which in turn reduces the cost of purchasing the
transmitter and using the
electrical power for it. For WABW and WCES, this makes them one of the few television stations in the country to operate on low-band VHF channels (2 to 6), which require larger receiving antennas, are prone to
tropospheric ducting (
weather) and
impulse noise, make
mobile TV (
ATSC-M/H) difficult, and for 5 and 6 are also an obstacle to expanding the
FM broadcast band. The high-band VHF channels also have these problems, but not to a major extent. ==Cable and satellite availability==
