While announcing its new Fall schedule this week, Bell Media announced that Discovery Channel HD, a high definition version of the Discovery Channel, will go on-air this fall.

If you're scratching your head thinking, didn't Canada already have the Discovery Channel in HD then you are not alone.

Discovery HD first went on air on August 15, 2003 and continued until August 2, 2010 when it was replaced by Discovery World HD.

The original Discovery HD ran a unique schedule of primarily HD programming which overlapped but did not mimic the standard definition version of the Discovery Channel.

The new Discovery HD will simply be a simulcast of the standard definition (SD) version which suggests some of its programming will simply be upconverts of SD programming.

Bell says it will make a separate announcement of the Discovery HD simulcast channel at a later date.

In the meantime, you can discuss the new HD channel in Digital Home's Canadian Television Industry / Channels and Providers forum .
