Maryland Public Television
Maryland Public Television (MPT) is the Public Broadcasting Service (PBS) member state network for the U.S. state of Maryland. It operates under the auspices of the Maryland Public Broadcasting Commission, an agency of the Maryland state government that holds the licenses for all PBS member stations licensed in the state. Studios are located in the unincorporated community of Owings Mills in northwestern Baltimore County. MPT operates six full-power transmitters that cover nearly all of the state, plus Washington, D.C., and parts of Virginia, West Virginia, Delaware, and Pennsylvania. History
WMPB (licensed to Baltimore) first signed on in 1969 as the first station of the Maryland Center for Public Broadcasting; it gained satellite stations in Salisbury, Hagerstown, and Annapolis between 1971 and 1975, resulting in a formation of a statewide public television network. The network adopted its current name in 1984. Maryland Instructional Television (Maryland ITV), a division of the State Department of Education, was also housed at the network until 1991. On July 4, 1987, WFPT (licensed to Frederick) signed on to fill coverage gaps in the outer Washington market, while WGPT in Oakland began operations to cover the extreme west of the state, much of which previously had no local television service at all. About 1999, the network launched an afternoon Britcom programming block, Afternoon Tea, replacing children's programming. By 2009, MPT was airing kids' programming during the day on its MPT Select channel. In September 2015, as part of budget cuts, MPT outsourced its master control operations to Public Media Management—a joint venture of Boston PBS member WGBH and Sony Corporation. Productions

The MPT stations are:

WGPT is assigned to the Pittsburgh, Pennsylvania market and elects must-carry status on satellite providers there. For the purposes of pay-television carriage, WMPT and WMPB are assigned to the Baltimore market, while WFPT and WWPB are assigned to Washington–Hagerstown and WCPB to Salisbury. Notes:
1. Aside from their transmitters, the MPT stations (except WMPB) do not maintain any physical presence in their cities of license. 2. WMPB used the callsign WETM during its construction permit from 1967 to 1968. 3. WWPB used the -TV suffix in its callsign from its 1974 sign-on to October 15, 1976. 4. WMPT used the callsign WAPB (Annapolis) from its 1975 sign-on to July 4, 1984. 5. WGPT and WFPT were both first licensed in 1979 as translators W36AB and W62AY, respectively. They were later replaced by full-powered licenses from the same transmitter sites. Technical information
The stations' digital signals are multiplexed:

Analog-to-digital conversion 
MPT's stations shut down their analog signals on June 12, 2009, the official date on 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:
 WMPB shut down its analog signal, over UHF channel 67; the station's digital signal remained on its pre-transition UHF channel 29, using PSIP to display the station's virtual channel as its former UHF analog channel 67, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition. WMPT shut down its analog signal, over UHF channel 22; the station's digital signal remained on its pre-transition UHF channel 42, using PSIP to display the station's virtual channel as its former UHF analog channel 22. WCPB shut down its analog signal, over UHF channel 28; the station's digital signal relocated from its pre-transition UHF channel 56, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to its analog-era UHF channel 28. WWPB shut down its analog signal, over UHF channel 31; the station's digital signal remained on its pre-transition UHF channel 44, using PSIP to display the station's virtual channel as its former UHF analog channel 31. WGPT shut down its analog signal, over UHF channel 36; the station's digital signal relocated from its pre-transition UHF channel 54, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition, to its analog-era UHF channel 36. WFPT shut down its analog signal, over UHF channel 62; the station's digital signal remained on its pre-transition UHF channel 28, using PSIP to display the station's virtual channel as its former UHF analog channel 62, which was among the high band UHF channels (52–69) that were removed from broadcasting use as a result of the transition. Spectrum reallocation
As a part of the repacking process following the 2016–2017 FCC incentive auction, channels 38 through 51 were removed from television broadcasting. None of MPT's stations sold their allocations, but five of them moved channels within the UHF band: WMPT moved to channel 21, WMPB to channel 22, WWPB to channel 29, WGPT to channel 26, and WCPT to channel 16. ATSC 3.0
MPT joined the Baltimore market's ATSC 3.0 lighthouse station, hosted at WNUV, on June 24, 2021. In return, WMPT and WMPB hosts WNUV's main channel (54.1) to preserve coverage for existing ATSC 1.0 TV sets. Awards
For 2008, MPT received 14 Emmy Award nominations from the National Capital Chesapeake Bay Chapter of the National Academy of Television Arts and Sciences (NATAS). MPT received Emmys for Eatin' Crabs Chesapeake Style, two awards for Bob the Vid Tech: The Mystery of the Missing Pizza and one for ArtWorks: Manuel Barrueco Special. MPT received two 2008 CINE Golden Eagle Awards for The Transformation Age: Surviving a Technology Revolution with Robert X. Cringely, a coproduction of MPT/University of Maryland Robert H. Smith School of Business, and Lethal Landscapes: Canvases of the Combat Artist. For 2007, the station received 11 nominations and won 1 National Capitol Emmy including 3 nominations for their regional The War series and 5 nominations for Outdoors Maryland. Motorweek also received the Board of Governors Award. References
