Starz HD is a high-definition simulcast feed of Starz that broadcasts in the 1080i resolution format. In addition to its main channel, Starz also operates high-definition simulcast feeds of its five multiplex channels. When it was launched in December 2003, the simulcast covered only the east and west coast feeds of the main Starz channel. An enhanced-definition simulcast feed and a separate HD channel called Sharper Movies HD, that would have broadcast in the 1080i format and be structured similarly to the original format of sister channel Encore's MoviePlex (in which Sharper Movies would broadcast programming from each Starz channel in daily sampler blocks), were also planned. Plans for the latter service were dropped because of a lack of interest from providers to charge a premium fee for the network. HD feeds of Starz Kids and Family, Starz Comedy and Starz Edge, followed in 2007.
