CBOT-DT, virtual channel 4.1 (UHF digital channel 25), is a CBC Television owned-and-operated station licensed to Ottawa, Ontario, Canada. The station is owned by the Canadian Broadcasting Corporation, as part of a twinstick with Ici Radio-Canada Télé station CBOFT-DT (channel 9). The two stations share studios at the CBC Ottawa Broadcast Centre on Queen Street (across from the Confederation Line light rail station) in Downtown Ottawa, alongside the main corporate offices of the CBC; CBOT-DT's transmitter is located on the Ryan Tower at Camp Fortune in Chelsea, Quebec, north of Gatineau.
On cable, the station is available in high definition on Rogers Cable digital channel 514 in the Ottawa area.[1] On satellite, it is carried on Shaw Direct channel 144[2] and Bell Satellite TV channel 1040.[3]
CBOT-DT serves as the default feed on CBC's live streaming internet video service, CBC Gem, and the only one available in Canada without registering an account with the CBC.[4]
History
![[icon]](/wiki/File:Wiki_letter_w_cropped.svg){kind=small} | This section needs expansion with: information on the history of CBOT. You can help by adding to it. (June 2013) |
CBOT went on the air for the first time on June 2, 1953, becoming the third television station in Canada. Before the launch of Télévision de Radio-Canada station CBOFT, CBOT aired both English and French-language programs.
During the late 1970s into the early 1980s, CBOT was known as "CBC 4 Ottawa", and its newscasts were known as CBC 4 News. In 1980, CBOT's 6 p.m. newscast was anchored by Ab Douglas, and by Joe Spence at 11:27, following The National. During the mid-1980s, the station was known as "CBOT 4", now "CBC Ottawa".

Transmitters
CBOT operated six analog television rebroadcasters in Eastern Ontario and included communities such as Pembroke. Due to federal funding reductions to the CBC, in April 2012, the CBC responded with substantial budget cuts, which included shutting down CBC's and Radio-Canada's remaining analog transmitters on July 31, 2012.[5] None of CBC's or Radio-Canada's television rebroadcasters were converted to digital.
Digital television
Digital channel
| Channel | Video | Aspect | PSIP short name | Programming[6] | Carrier frequency | Modulation | Symbol rate |
|---|---|---|---|---|---|---|---|
| 4.1 | 720p | 16:9 | CBOT-DT | Main CBOT-DT programming / CBC Television | 537250 kHz | 8VSB | 6000000 |
Analogue-to-digital conversion
On August 31, 2011, when Canadian television stations in CRTC-designated mandatory markets transitioned from analogue to digital broadcasts,[7] the station's digital signal remained on UHF channel 25. However, through the use of PSIP, digital television receivers display CBOT-DT's virtual channel as 4.1.
