Channel 4 - Channel 4 HD

Channel 4 HD

On 10 December 2007, Channel 4 launched a high definition television simulcast of Channel 4 on Sky+ HD, after British Sky Broadcasting agreed to contribute toward the channel’s satellite distribution costs. On 31 July 2009, Virgin Media added Channel 4 HD on channel 146 as a part of the M pack. On 25 March 2010 Channel 4 HD appeared on Freeview channel 52 with a placeholding caption, ahead of a commercial launch on 30 March 2010, coinciding with the commercial launch of Freeview HD. On 19 April 2011, Channel 4 HD was added to Freesat on channel 126. As a consequence, the channel moved from being free-to-view to free-to-air on satellite during March 2011. With the closure of S4C Clirlun in Wales on 30 November 2012, on Freeview, Channel 4 HD will launch in the Wales on 1 December 2012.

The channel carries the same schedule as Channel 4, broadcasting programmes in HD when available. Initially this has been mostly American imports (such as Ugly Betty for example) and movies, however, original programming such as Hollyoaks and Skins have been broadcast in HD. Although the intention is to increase the amount of "home grown" material being broadcast in HD. It has been announced as the UK's first full-time high definition channel from a terrestrial broadcaster.

Previously, in the summer of 2006, Channel 4 ran a six month closed trial of HDTV, as part of the wider Freeview HD experiment via the Crystal Palace transmitter to London and parts of the home counties, including the use of Lost and Desperate Housewives as part of the experiment, as US broadcasters such as ABC already have an HDTV back catalogue.
