What is HD-TV?

High Definition is a digital broadcast signal with more lines of resolution than analog Standard Definition (1080i compared to 480i). HD-TV is also broadcast in a different aspect ratio, giving you a wider image (16:9 compared to 4:3). HD-TV also sounds different, with audio in either Dolby Digital stereo or Dolby Digital 5.1.

What does this mean to you, and what about CTV Ottawa?

If you've already entered the world of HD-TV by acquiring an HD television, you'll now be able to get CTV network programming in HD here in Ottawa, provided you have an HD source. CTV Ottawa HD is available through Rogers on channel 518 and Vidéotron on channel 607, and we will continue to update you once other cable and satellite providers are carrying our HD signal.

If you're not yet into HD-TV, don't worry. CTV will continue to broadcast our Standard Definition signal here in Ottawa on Rogers Cable channel 7, OTA channels 6, 8, and 47 (depending on where you live), Bell TV 229 and Shaw TV 311, or simply check with the local cable provider in your area.

When will CTV News Ottawa be available in HD-TV?

Good question -we're working on it. The switch to carry HD programming required some major changes to our infrastructure here at CTV in Ottawa, and so will the switch to produce our News in High Definition. That means changing all of our cameras, edit suites, and studio equipment. It's a big investment, but we're committed to doing it. In the meantime, CTV News Ottawa will be seen on our HD service. Our Standard Definition signal will be "up-converted" for broadcast on CTV HD.
