A check for BBC News
Use the local edition label and one current scheduled programme. If a cable or internet guide abbreviates the name, identify the service using the broadcaster reference and the visible region before replacing its station ID.
Check the station edition
Record one programme and its scheduled local time on the broadcaster page. Compare it with the channel label and time displayed in your player.
Check the guide if the live feed works
If the programme matches the live edition but the guide is wrong, confirm the channel mapping before changing the device clock.
