Food Network HD is a 1080i high definition simulcast of Food Network. It originally aired a different lineup than the SD version, with only HD programs. On March 31, 2008 Food Network (along with HGTV) relaunched an HD simulcast of its standard definition feed. As a result, the programming is now identical on both channels, with upconverted and stretched versions of standard definition programs being shown when no high definition version is available.
Some cable companies broadcast the HD versions of programming on the east coast time slot (similar to satellite practices) with the SD version being broadcast in its normal timeslot. This only impacts cable networks and does not change local programming.
