After years of publicity, Perth, Angus, Dundee and parts of Fife have finally joined the “digital revolution.”
Unprepared viewers faced blank screens as the analogue television signal was switched off.
Shortly after midnight, analogue BBC2 was turned off permanently at the Angus transmitter.
Engineers promptly started to switch on digital signals at 23 relay transmitters serving more than 75,000 homes.
The households were then able to receive Freeview for the first time.
The changes also affected existing Freeview viewers, some of whom found BBC channels missing.
These services have moved to new frequencies and can be restored by retuning Freeview TVs and boxes.
The second and final stage of switchover takes place on August 18, when the remaining analogue channels will be switched off permanently.
Meanwhile, the switchover help scheme is still welcoming applications from eligible older and disabled people, who may need help to convert their television.
Paul Hughes, Digital UK’s national manager for Scotland, said, “This is by far the largest switchover Scotland has seen, affecting more than 200,000 households with many people receiving Freeview channels for the first time.
“We are now encouraging any viewers who still don’t have the necessary equipment to get ready in time for August 18.
“Anyone who needs advice should contact 08456 505050 or sign up for the help scheme if they are eligible.”
