WPTD is a television station in Dayton, Ohio that is a member of the Public Broadcasting Service. It broadcasts in digital on channel 16, and is relayed by W17AA in Celina, Ohio and W63AH in Maplewood, Ohio.

WPTO, WPTD's sister station, is a member of PBS, licensed to Oxford, Ohio. It broadcasts digitally on channel 28 but is displayed on-screen as channel 14, its former analog and present virtual channel, via the PSIP protocol. Oxford is located in the Cincinnati market, and WPTO's digital transmitter is on the same tower as WXIX-TV, Cincinnati's Fox affiliate.

WPTD brands itself ThinkTV16, while WPTO brands itself ThinkTV14. Together, the two stations are known on-air as the ThinkTV Network and operate as a subsidiary of Public Media Connect, a regional non-profit company that also owns Cincinnati's PBS member station, WCET.

Neither WPTD nor WPTO is a satellite of the other: Master control operations for both stations are performed at ThinkTV facilities in Dayton.[1] Individual programs may be shared between the two stations. However, each station is separately programmed and scheduled; there is virtually no overlap, except during pledge drives.

Both stations' signals are multiplexed, each broadcasting one high-definition channel, and several standard definition channels.

WPTD's broadcast coverage includes much of southwestern Ohio, including Dayton and Cincinnati, as well as portions of eastern Indiana. WPTO's smaller coverage area largely overlaps that of WPTD, but is more concentrated in the extreme southwest corner of Ohio, providing a stronger signal to Cincinnati, weaker to the Dayton area. Both stations are available on Time Warner Cable throughout southwestern Ohio, though some systems may offer only WPTD's set of multiplexed channels or WPTO's, depending on their location.

History

WPTD began in 1972 as WOET-TV, operated by the Ohio Educational Broadcasting Network Commission (OEB). Prior to that, Channel 16 was occupied by a commercial independent and sometime ABC-affiliated station, WKTR-TV.[2] That station was owned by Kitty Hawk Television Corporation and licensed to Kettering when it began broadcasting in April 1967. It went dark in 1970, but returned to the air briefly in 1971 before giving up its license to the Federal Communications Commission, which reallocated the frequency as non-commercial.

WPTD's sister station, WPTO, began in 1959 as WMUB-TV, which was operated by Miami University.

The stations joined forces in 1975 under the banner of University Regional Broadcasting, a consortium of Miami, Wright State and Central State universities. WMUB-TV was the primary station for a year until 1976, when WOET-TV became the primary station. In 1977, the stations were transferred to a new community organization, Greater Dayton Public Television, and received their current callsigns.

From the creation of University Regional Broadcasting onward, the secondary station operated as a semi-satellite of the primary station, only rarely airing different, usually local public-affairs type, programs. This situation existed until cable television began to become widely available in the community. Both stations were carried on Dayton-area cable systems. As cable availability rose, the stations' programming was increasingly differentiated by Greater Dayton Public Television, and the stations eventually achieved separate programming and scheduling.

The stations rebranded themselves as the ThinkTV Network in 1998, though the legal name remained Greater Dayton Public Television.

On October 31, 2008, Greater Dayton Public Television and the Greater Cincinnati Television Educational Foundation, owner of WCET, announced plans to merge their resources into one non-profit organization serving all of Southwest Ohio, while maintaining separate identities.[3] The merger completed on May 8, 2009 with the formation of Public Media Connect, Inc. Both ThinkTV and CET operate as subsidiaries under the new organization.[4] The merger resulted in the July 2010 transfer of WCET's master control operations to ThinkTV facilities in Dayton.[1]

Digital television

On May 1, 2003, ThinkTV marked the beginning of its conversion to digital technology with the introduction of four new digital program services and a digital simulcast channel for ThinkTV16/WPTD. ThinkTV16's digital channel was UHF channel 58. One year later in May of 2004, ThinkTV entered phase two of its digital conversion with the installation of new digital Master Control equipment and the introduction of new digital channels for ThinkTV14/WPTO. ThinkTV14's digital channel was UHF channel 28.

During this period, the digital channels were 16.2 - ThinkTV 16 DT, 16.3 - ThinkTV 16 Again, 16.4 - ThinkTV 16 Create, 16.5 - ThinkTV 16 Ohio, 16.6 - ThinkTV HD; 14.2 - ThinkTV 14 DT, 14.3 - ThinkTV 14 Prime, 14.4 - ThinkTV 14 Learn, 14.5 - ThinkTV 14 World and 14.6 - ThinkTV HD. Note that neither WPTD nor WPTO had an X.1 subchannel; the X.2 subchannels matched their respective analog channels; also, 16.6 and 14.6 carried identical PBS HD programming, which was distinct from the separate analog programming on WPTD and on WPTO.

ThinkTV switched to an all digital service on May 1, 2009, as part of the DTV transition in the United States. On this date, ThinkTV16 ended its digital broadcast on channel 58 and switched channel 16 from an analog broadcast to a digital one. ThinkTV14 ended its analog broadcast on channel 14. It remained on its digital channel, 28, using the PSIP protocol to display its virtual channel as 14.

The subchannels were realigned as shown below. Note that 16.3 was changed from ThinkTV 16 Create to ThinkTV 16 Life later in 2009.

The digital signals of WPTD and WPTO are both multiplexed:

WPTD

Digital channels
Channel Name Programming
16.1 ThinkTV 16 HD Regular WPTD programming in high-definition
16.2 ThinkTV 16 Again Repeat broadcasts of WPTD primetime shows
16.3 ThinkTV 16 Life Lifestyle and how-to programming
16.4 ThinkTV 16 Ohio Ohio-specific programming, including The Ohio Channel
16.5 ThinkTV 16 DT Regular WPTD programming

WPTO

Digital channels
Channel Name Programming
14.1 ThinkTV 14 HD Regular WPTO programming in high-definition
14.2 ThinkTV 14 Prime Repeat broadcasts of WPTO primetime shows
14.3 ThinkTV 14 Learn PBS Kids programming and college telecourses
14.4 ThinkTV 14 World World news from PBS World; programming from The Ohio Channel
14.5 ThinkTV 14 DT Regular WPTO programming

Note that while the "DT" designation on 16.5 and 14.5 appears on the ThinkTV website and displays on-screen via PSIP, it is omitted from ThinkTV's advertising and on-screen "bugs".

Translators

Per FCC filings, translator station W17AA in Celina had authorization in 2009 to flash-cut to digital operations on channel 17, at a tower site near its existing analog tower. However, before this conversion could be completed, W17AA suspended operations on January 5, 2011 due to circumstances beyond Greater Dayton Public Television’s control, namely a loss of site. The tower owner, the State of Ohio, has plans to dismantle the tower utilized by W17AA, and in anticipation has disconnected power to the tower site location. As a result, GDPTV was forced to suspend operations over W17AA. On January 14, 2011, GDPTV requested a six month authorization to maintain silent (off-air) status. GDPTV is now beginning the process of considering its options for modification of the W17AA license to allow for its resumption of service.

Also per FCC filings, translator station W63AH in Maplewood had authorization in 2009 to switch to digital operations on channel 32. Before this conversion could be completed, W63AH suspended operations on March 30, 2010. GDPTV was forced to take the station off-air due to a loss of site, following a change in ownership for the translator station’s licensed tower location. On April 5, 2010, GDPTV requested a six month authorization to maintain silent status.
