Channel 4 HD, which will be available without additional subscription to viewers with a Sky HD box and a viewing card, will carry high definition versions of the channel's programming where available. The channel will be located on channel 140, adjacent to Channel 4+1, E4, E4+1, More4 and More4+1.
Initially the channel will launch on Sky, but Channel 4 told DS this morning that there is no exclusive arrangement with the satellite broadcaster and that Channel 4 HD is expected to rollout on other platforms "in the future".
"Channel 4's aim is to offer our viewers maximum flexibility in accessing our high quality programmes and content at a time and in the format of their choosing," said Channel 4 new media director Rod Henwood. "HD is a fast growing consumer technology and we believe our viewers will welcome the opportunity to watch their favourite Channel 4 shows in high definition."
Channel 4 will be the first terrestrial broadcaster to offer a full-time high definition simulcast of its main service on Sky.
"High definition is transforming the TV experience and customers are responding in record numbers to the fundamental improvement in quality and sound quality," said Brian Sullivan, Sky's customer group managing director. "We want our customers to enjoy access to the widest choice of HD programmes so we're extremely excited about the launch of Channel 4 HD. Be it sports, movies, documentaries or entertainment, Sky HD customers can now access the richest selection of content in HD."
