Showtime HD is a high definition simulcast feed of Showtime that broadcasts in the 1080i resolution format. In addition to its main channel, all of Showtime's multiplex channels also broadcast in the format, though availability of all of the HD feeds varies by provider. Showtime HD is available through virtually all providers which carry Showtime, along with Showtime's streaming services. Films shown on Showtime's HD simulcast feeds are broadcast in their native aspect ratio if that version is provided by the studios that maintain pay television distribution rights with the channel.
