Discovery Channel HD, a high definition version of the Discovery Channel, launched today on Bell Satellite and Bell Fibe TV.

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 is a high definition simulcast of the standard definition (SD) version which airs today that also includes Dolby Digital 5.1 sound. The station is available on Fibe TV on channel 1520 and on Bell Satellite TV (BSTV) on channel 1602.
