Twin Cities Public Television (TPT) is a non-profit organization based in Saint Paul, Minnesota, United States, that operates the Twin Cities' two Public Broadcasting Service (PBS) member Public television stations, KTCA-TV (digital channel 34, PSIP channel 2.1) and KTCI-TV (digital channel 23, PSIP channel 2.3). It produces programs for regional and national television broadcast, operates numerous Web sites, and produces rich media content for Web distribution.

History[edit]

Tcptv.jpg

Twin Cities Public Television was incorporated in 1955 as Twin City Area Educational Television.

KTCA (channel 2) began broadcasting as the first non-commercial Public television station in the state on September 16, 1957 from shabby, WWII wooden barracks-type structure on the University of Minnesota Agricultural Campus. The studios and offices were moved in the '60 to what was known as the Minnesota Statehood Centennial Memorial Building for Education Television, at 1640 Como Avenue in Saint Paul. (Incidentally, that building now houses another Twin Cities commercial television station-WUCW, channel 23.) KTCA's first program was "Exploring Science". A second station, KTCI (channel 17), was launched on May 4, 1965. Channel 17 was originally assigned to the Tedesco Brothers in the early 1950s to be a Commercial broadcasting station, WCOW-TV (see KDWB) affiliated with the DuMont network, but this station never made it to air. In 1967, KTCA became the first educational television station in the United States to broadcast in color, then in 1977, it changed its corporate name to the current Twin Cities Public Television.

On September 16, 1999, the stations began their first digital television broadcasts, 9 years after moving to their current building at 172 4th Street East in downtown Saint Paul in 1990. In 2000, KTCA and KTCI were rebranded tpt2 and tpt17, paving the way for the larger family of digital broadcast services to come. In August 2003, TPT became the first broadcaster in Minnesota to launch a channel, tptHD, fully devoted to high-definition programming, and on September 16, 2005 the organization launched a full-time digital channel, tptMN, devoted entirely to local and regional programs.

In December 2005, the organization began distributing many of its productions online, making programs available through iTunes, Google Video, and Yahoo! Podcasts among others. Its website, features streaming video as well as video podcasts. In 2007, TPT also plans to begin offering Video-On-Demand (VOD) thorough local cable providers.

KTCA's Nielsen ratings are among the highest of any PBS station in the country.[citation needed]

The Minnesota Channel[edit]

Main article: Minnesota Channel

The Minnesota Channel (tptMN) is a full-time statewide network originating at Twin Cities Public Television and carried on digital subchannels of nine stations. It features programming related to Minnesota and Wisconsin, including ethnic and public-affairs programming.

In early 2003, TPT began setting aside time on KTCI for the "Minnesota Channel", an evening dedicated to local and regional related programming, which expanded to a full-time digital channel on September 16, 2005. The Minnesota Channel was expanded region-wide in Minnesota and North Dakota in February 2008.

Digital television[edit]

Digital channels[edit]

The stations' digital channels are multiplexed:

Channel Video Aspect PSIP Short Name Programming[1][2]
KTCA-DT 2.1 1080i 16:9 tpt 2 Main KTCA-TV programming / PBS
KTCA-DT 2.2
KTCI-DT 23.7
480i 4:3 tpt MN Minnesota Channel
KTCI-DT 2.3 tptLife Main KTCI-TV programming / PBS
KTCA-DT 2.4 tpt Wx Weather radar and NWS audio KEC65

KTCA-DT and KTCI-DT began broadcasting on channels 16 and 34 on September 16, 1999.

Analog-to-digital conversion[edit]

TPT rearranged the on-air lineup on February 18, 2009.[3] TPT continued to use both KTCA-DT and KTCI-DT's transmitter, but shut down the separate tpt17 service and unified all over-the-air channels as virtual subchannels of 2. TPT's stations shut down their analog signals at 9 a.m. on June 12, 2009, the official date in which full-power television stations in the United States transitioned from analog to digital broadcasts under federal mandate. The station's digital channel allocations post-transition are as follows:[4]

  • KTCA-TV shut down its analog signal, over VHF channel 2; the station's digital signal remained on its pre-transition UHF channel 34. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 2.1.
  • KTCI-TV shut down its analog signal, over UHF channel 17; the station's digital signal remained on its pre-transition UHF channel 16. Through the use of PSIP, digital television receivers display the station's virtual channel as 2.3

Subchannels 2.1, 2.2 and 2.4 broadcast through KTCA-DT's transmitter while 2.3 and 23.7 broadcasts through KTCI-DT's transmitter. Some of the bandwidth on KTCI-DT is being reserved for future broadcast services or to lease to commercial interests. During severe weather, KTCA Channel 2.4 airs a live broadcast from NOAA Weather Radio station KEC65.

The then-new channel lineup was originally meant to coincide with the DTV transition. When the transition's mandatory cutoff was delayed, TPT announced the new lineup would still go forward and they would continue their analog service until the new cutoff. Until then KTCA-TV simulcasted tpt 2 and KTCI-TV simulcasted tptLife on their analog signals.

Transmission Technical Data[edit]

KTCA and KTCI are broadcast from the KMSP Tower in Shoreview, Minnesota. In addition, there are three digital translators in southern Minnesota relaying KTCA and one relaying KTCI.
