The BBC has set a target date of April 2022 to complete the roll out of BBC One regions in high definition (HD).
Regional versions of BBC One are already available in HD on Sky’s Glass online platform, Virgin Media (cable and internet delivered Virgin Media Stream) and BT TV, albeit in some regions this upscaled to HD. The target confirms the in intention to roll out BBC One HD to all regions on satellite and terrestrial based platforms, including Sky, Freesat, Freeview, and Youview.
This work will involve splitting the terrestrial (Freeview/Youview) multiplex PSB3 (also known as BBC B) into further regions, to allow each version of BBC One to broadcast terrestrially. This will also allow ITV to show all of their local regions in HD on Freeview, and will end the need for the red screen on BBC One HD advising viewers to switch back to the standard definition version.
Another part of the work required will see additional BBC One HD streams added on satellite, as each version of the channel needs a separate stream to broadcast, with the Sky or Freesat receiver selecting the relevant version of the area the viewer is located in. HD versions of BBC Two Northern Ireland, BBC ALBA and BBC Parliament are also on their way.
Due to bandwidth restrictions, the BBC is understood to be planning to phase all satellite services from the DVB-S broadcast standard to DVB-S2. DVB-S2 is more efficient, but this will mean that users of older non-HD equipment will eventually lose access to BBC services, if they choose not to upgrade equipment. One benefit from this is that there will no longer be a need for standard and high definition duplicates on each channel. This will also affect BBC radio services broadcast on satellite, as these utilise leftover space not large enough for TV broadcasts.
More details will be published on this website as the plans develop.
