A number of changes to BBC World Service channels and stations on the Hotbird satellite have come into effect.
The BBC Arabic TV channel is now HD-only on Hotbird 13°E after the standard definition channel was turned off last week. It ended an HD/SD simulcast lasting just over six months.
The change is part of a removal of BBC services from Hotbird transponder 94 and also affects BBC World Service radio, including feeds for both Europe, Middle East and Horn of Africa, plus BBC Arabic radio. Only the standard definition version of BBC World News television remains on the transponder.
All services are now on Hotbird transponder 50, 11727V, symbol rate 29900, FEC 3/4. The transponder uses the broadcast standard DVB-S2, which means older SD-only satellite receivers will no longer any of the affected television and radio services via Hotbird
