KERA-TV, virtual channel 13 (UHF digital channel 14), is a PBS member television station serving the Dallas–Fort Worth Metroplex that is licensed to Dallas, Texas, United States. The station is owned by North Texas Public Broadcasting Inc. KERA maintains offices located on Harry Hines Boulevard (east-northeast of I-35E) in downtown Dallas, and its transmitter is located south of Belt Line Road in Cedar Hill. The station's signal is relayed on low-power translator station K44GS-D in Wichita Falls, which provides PBS programming to the Texas side of the Wichita Falls–Lawton market.〔()〕 KERA-TV also serves as the default PBS station for the Abilene, San Angelo and Tyler/Longview/Lufkin/Nacogdoches markets, as well as the Texas side of the Sherman/Ada market; none of these areas have PBS members of their own. It is also available on cable in Hillsboro, Waco and Texarkana. KERA was formerly carried on cable in Amarillo, until PBS station KACV-TV signed on in that market in 1988. The station's call letters, which are said to represent a "new ''era'' in broadcasting", are shared with NPR member station KERA (90.1 FM); while there is cross-promotion between the two stations, each operates their own pledge drives. ==History== KERA-TV began its life as a broadcasting arm of the Dallas Independent School District and was developed by local nonprofit Area Education Television Foundation, Inc. (which later evolved into North Texas Public Broadcasting), in cooperation with the district.〔(No author.) "White sets plans for TV school", ''The Dallas Morning News'', Oct. 15, 1958, page 8A.〕 The district paid the station to carry instructional telecourses that it would produce for broadcast on channel 13. Southern Methodist University originally applied for the channel 13 allocation in the late 1950s, but had trouble raising enough funds for its start up costs. DISD superintendent W. T. White announced in October 1958 that the station was expected to sign on the air by the beginning of the 1959-60 school year, with programming to include Spanish language instructional programming for area elementary school students.〔 The foundation had difficulty in meeting its fundraising goals to start broadcasting; by May 1959, the foundation was said to be $265,000 short of its $890,000 target to cover the proposed station's first two years of broadcasting.〔"Weather Vane" (news briefs column), ''The Dallas Morning News'', May 3, 1959, page 29.〕 KERA's early operation benefited frequently through help from the commercial broadcasters in the Metroplex. The station's original license application had received permission by the Federal Communications Commission to broadcast from Fair Park (on land donated to the station by the Dallas city government), but in 1960 the station applied to be permitted to broadcast from studios on Harry Hines Boulevard〔(No author.) "Approval by FCC asked by station", ''The Dallas Morning News'', Jan. 16, 1960, page 2.〕 that were set to be vacated by ABC affiliate WFAA-TV (channel 8), which was building new studio facilities at Young and Houston Streets to accommodate the operations of WFAA-AM-FM-TV as well as those of local newspaper ''The Dallas Morning News'' (ironically, WFAA-FM once held the KERA-FM calls now used by channel 13's radio sister);〔(No author.) "Contracts OK'd for building of WFAA studios", ''The Dallas Morning News'', Dec. 31, 1959, page 1A.〕 the building on Harry Hines, which the Dallas Independent School District purchased for $400,000, had been used by WFAA from its sign-on (as KBTV) in 1949. KERA-TV signed on the air on September 14, 1960. It temporarily operated from studios at the Davis Building in downtown Dallas, behind the original WFAA building, in two portable buildings that were made to resemble a schoolhouse; KERA migrated its operations to the Harry Hines Boulevard facility in April 1961. It used the original WFAA-TV transmitting facility until it moved its transmitter to a tower at Cedar Hill that is shared with KTVT (channel 11); the station's transmitter only covered Dallas and surrounding suburbs, until a new transmitter was installed on August 31, 1970 that expanded KERA's signal coverage into Fort Worth. In 1974, KERA became the first television station in the United States to broadcast episodes of ''Monty Python's Flying Circus'', and is often credited with introducing the program to American audiences. KERA parent North Texas Public Broadcasting signed on a secondary PBS member station in the market, KDTN (channel 2), on September 1, 1988. KERA used the station primarily to run educational and instructional programming that had previously filled much of the station's daytime schedule. KERA then shifted to offering primarily entertainment programming from PBS and other public television distributors. KERA sold KDTN to religious broadcaster Daystar – which bought the station in order to get a better signal in the market, selling its original flagship KMPX (channel 29, now an Estrella TV owned-and-operated station) in turn – in 2004. However, through a special arrangement, KERA announced plans to continue its digital programming on KDTN's digital signal, in order to free up bandwidth on KERA's main digital signal to allow the station to upgrade to high definition broadcasts. However, KERA has not needed additional subchannel bandwidth from KDTN as it operates only one additional subchannel service outside of its main signal. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「KERA-TV」の詳細全文を読む スポンサード リンク
