Digital UK London Countdown has been uploaded to the Alexandra Palace Television Society’s YouTube Channel.
TV presenter Christine Bleakley was in the pink as she marked the countdown to the digital TV switchover at the birthplace of television - Alexandra Palace.
The historic landmark was turned bright pink from 4-6th April to celebrate a year until the analogue television signal is officially turned off, leaving digital as the only option from April 4, 2012 onwards.
The Palace's bright pink TV tower, the venue from which the world's first regular, public, high-definition television broadcast began in 1936, could be seen for miles around.
Alexandra Palace managing director Rebecca Kane said: "This is where TV was born and so it's great that Ally Pally is where Digital UK chose to announce the next most significant advancement in TV - the digital switchover."
The switchover, which requires viewers to convert any old analogue TV sets before next year's deadline, will provide an extended freeview service in a range of widescreen and interactive options.
