On cable, the station is available in high definition on Rogers Cable digital channels 8 and 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
Channel 4 logo used by CBOT for several years in the early 1980s.

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".

News operation

CBOT-DT presently broadcasts 10 hours, 40 minutes of locally produced newscasts each week (with two hours each weekday, a half-hour on Saturdays and ten minutes on Sundays). CBOT airs local news programming in the form of a 90-minute newscast from 5 to 6:30 p.m. and a half-hour newscast at 11 p.m. on weekdays. On weekends, the station airs a half-hour 6 p.m. newscast on Saturdays and a ten-minute summary airs on Sundays at 11 p.m.

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.

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.
