Digital switchover involves the switch-off of the analogue terrestrial transmissions network that has been in place for more than 65 years - and its replacement with an all-digital terrestrial network.
At the moment digital and analogue signals are broadcast simultaneously. But whilst the analogue signal is maintained, the digital signal can’t be broadcast in full and at full power across the UK.
Switchover will affect all viewers who have any televisions through which they can only receive analogue services BBC1, BBC2, ITV, C4/S4C and (where available) Five services through the TV aerial.
Beginning in late 2007 it will take around four to five years to complete the switchover process and it will take place region by region. To view a map outlining each regions planned switch off date, click here.
How does Digital work?
With digital TV, sound and pictures from the broadcaster are converted into ‘bits’ of information and sent through an aerial, satellite, telephone line or cable. This digital signal is then turned back into pictures and sound by a digital box or a digital TV set.
Business and Digital
Much of the focus around digital switchover understandably focuses on its impact on the domestic environment. But the UK’s business community also needs to prepare for the change - in the Government’s own words:
"All existing TVs planned to be used to receive broadcasts after digital switchover will need to be converted to digital."
"This applies equally to TVs in non-domestic settings such as schools, universities (including halls of residence), libraries, places of work, hospitals, day care centres, residential care and nursing homes, pubs and bars, railway and airport waiting lounges, hotels, bed and breakfast accommodation, youth hostels, central government departments, prisons, leisure centres, armed forces establishments and local government offices, provided they are used to receive broadcast services and not only pre-recorded material or closed circuit TV."
"Organisations that provide television to customers or purchasing televisions will need to consider the impact of the Government's plans for switchover on their budgeting and purchasing decisions and in future contract negotiations with service providers. Local Authorities and Housing Associations may also want to consider making a similar assessment."
