The Scottish Channel 3 broadcaster confirmed the news on its Twitter account. The news follows confirmation last week from Northern Irish counterpart UTV that its HD service will launch this November.
The launch will allow satellite viewers in Central and Northern Scotland to watch shows including Coronation Street and X Factor in HD direct from the Sky or Freesat Electronic Programme Guide.
However, the April 2014 launch leaves STV viewers as the last in the UK to get an HD version of their Channel 3 service provider via Sky and Freesat. Viewers in the south of Scotland who fall within itv's Border TV region are currently already able to watch Channel 3 programmes in HD via itv HD Granada on satellite.
STV HD previously broadcast free-to-air on digital satellite, but did not appear on either Sky or Freesat channel guides, and had to be manually tuned in. No official reason has been provided as to why the service will not officially appear on Sky and Freesat for another seven months, but earlier this year STV pointed out that it had been "working with itv" to get their HD service officially launched on satellite.
STV HD is already available on Freeview HD and Virgin Media in Scotland.
- Meanwhile, itv Border has commenced running extended Lookaround bulletins for the Border region. Ofcom recently decreed that itv would have to increase programmes for the Border region, ending the previous arrangement, which saw Border and Tyne Tees viewers share part of their regional news programmes. itv Border will soon commence separate programming for the Border Scotland region, giving viewers in the Scottish part of the Border region further coverage of Scottish issues, including the forthcoming referendum.
updated 19/02/2014: STV HD's test service on satellite has closed ahead of the official launch in April.
