CBBC HD has been added to channel 73 and BBC Three HD to channel 105. Both channels will timeshare the bandwidth currently used by BBC Red Button HD, which is expected to go off air after providing 3D coverage of the Doctor Who 50th anniversary special in November.
Both CBBC and BBC Three HD will be universally available on Freeview HD, with 98.5% population coverage. The official launch date for these services is yet to be confirmed, but both services are expected to be on air by mid-December.
BBC Four HD, CBeebies HD and BBC News HD are also scheduled to launch soon, but due to capacity restraints, will launch on one of the two new Freeview HD extra multiplexes. These extra multiplexes will cover 70% of UK households by the end of June 2014.
In London, multiplex operator Arqiva is testing one of the extra multiplexes that will cater for the expanded Freeview HD service from London's Crystal Palace transmitter. Al Jazeera English HD has commenced testing on channel 108 for viewers with Freeview HD receivers in and around the Capital. A rescan may be required to see the test service.
