CBLT-DT, virtual channel 5 (UHF digital channel 20), is the flagship station of the English language service of CBC Television located in Toronto, Ontario, Canada. The station is owned by the Canadian Broadcasting Corporation, as part of a twinstick with Ici Radio-Canada Télé owned-and-operated station CBLFT-DT (channel 25), which is operated through corporate subsidiary Société Radio-Canada. CBLT-DT maintains studio facilities based at the Canadian Broadcasting Centre on Front Street West in downtown Toronto, which it shares with national cable news channel CBC News Network and also houses the studios for most of CBC's news and entertainment programs; CBLT maintains transmitter facilities located atop the CN Tower in downtown Toronto. On cable, the station is available on Rogers Cable channels 6 and 127, and in high definition on digital channel 514. CBLT-DT serves as the default CBC affiliate for the Thunder Bay and Peterborough television markets, after CKPR-DT in Thunder Bay disaffiliated from the network September 1, 2014 and CHEX-DT in Peterborough and its sister station CHEX-TV-2 in Oshawa both followed August 31, 2015, in both cases to become affiliates of the CTV Television Network. ==History== The station first signed on the air on September 8, 1952, originally broadcasting on VHF channel 9. It is the oldest television station in the province of Ontario, and the second oldest in Canada after Ici Radio-Canada Télé flagship station CBFT-DT in Montreal. The station's first broadcast was prefaced by the inadvertent incorrect display of the CBC's national network logo; conflicting accounts say it was either displayed upside-down or backwards, due to the incorrect insertion of the slide. No such error was made two days earlier when CBFT signed on.〔(Canadian Communications Foundation - Fondation Des Communications Canadiennes )〕 CBLT originally broadcast from a series of smaller studios (which were torn down and replaced by a building that now houses the National Ballet School) on Jarvis Street, next to its old transmitter. On January 19, 1953, a microwave link between Buffalo, New York and Toronto was activated, allowing the live telecast of programs from the American television networks. A few months later, on May 14, 1953, CBC Television's stations in Montreal (CBMT-DT) and Ottawa (CBOT-DT) became the first connections within the Trans-Canada Microwave system. In 1956, CBLT moved to VHF channel 6 and increased its effective radiated power from 25 to 100 kW. The change in frequency was made to accommodate the eventual licensing of a second privately owned local station for Toronto, which eventually became CFTO (channel 9) when that station was licensed at the end of 1960. Then in 1972, CBLT relocated to channel 5 in order to allow two new stations – CKGN (now CIII-DT) in Paris and a repeater of Ottawa-based CJOH in Deseronto – to use channel 6. CBLT moved its transmitter facilities to the CN Tower when it opened in 1976; its signal was transmitted from the tower for the first time on May 31, 1976. It eventually moved its operations to the Canadian Broadcasting Centre on Front Street. 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「CBLT-DT」の詳細全文を読む スポンサード リンク
