Access HDTV channel guides by visiting sites such as TVGuide.com, TV.com and AntennasDirect.com, as of 2015. Some sites display programming on the channels as well as the specific channel numbers and network names. Many cable and satellite providers also offer HDTV channel guides on their websites.
In addition to general news coverage of television programming and events, TVGuide.com maintains a directory of channel programming for the U.S. time zones as well as a select set of international broadcasting stations. Access the guide by visiting the site and clicking on the What's On link in the main navigation bar. The site displays the current and upcoming programming on the various networks as well a brief description of certain programs. To filter results so that only HD channels and programming appear, click on the Preferences tab of the guide, and check the box that reads Only Show HD Channels under the Channel Filters section.
TV.com offers a similar tool that shows the names and times of shows along with a button for quickly filtering only HD content. The method for accessing the HDTV channel guide on a specific cable network varies between providers, with some requiring users to enter location information to view specific details. Many providers also only provide specific broadcast details through the interactive menus from the set-top box.
