On 3 April 2008, Ofcom published its final decision for the HDTV transmission format: DVB-T2 and MPEG-4. Initially there were to be three HD services available: BBC HD, ITV HD/STV HD and Channel 4 HD/S4C Clirlun. Channel 5 HD was due to launch during 2010 but was unable to reach 'key criteria' to keep its slot. Spare allocation on multiplex B was handed over to the BBC, two years to the date when it was anticipated that further capacity on multiplex B would revert to the control of the BBC Trust. On 3 November 2010, BBC One HD launched on Freeview HD. It is available in addition to the existing BBC HD channel. During 2011, Ofcom gave the Commercial Public Service Broadcasters another opportunity to apply to provide an additional HD service from 2012.
