Freeview viewers receiving a signal from the Sheffield transmitter will need to retune their equipment on Wednesday 17 March to continue watching BBC services. The retune is required to prepare local transmitters for the future rollout of HD (high definition) channels on Freeview. Freeview will launch an information campaign in Sheffield ahead of the change, reminding viewers to get ready. The campaign will include newspaper and radio ads, and on-screen messages. Most viewers find retuning their Freeview equipment straightforward and many do so regularly to ensure they are up to date with the latest channel line-up. If people do need further help they can visit an information website at www.tvretune.co.uk to download easy-to-follow retuning guides for the most popular Freeview equipment, or call the automated TV Retune advice line on 08456 05 11 22. A video showing people how to retune is also available here . The technical changes will take place in the early hours of the morning of 17 March and are expected to be complete by 6am. All Freeview boxes, Freeview+ digital TV recorders, BT Vision or Top Up TV boxes, and digital TVs can be retuned at any point after this. Any Sheffield viewers who find they are missing channels are advised to retune equipment as soon as practicable on 17 March*. Satellite and cable viewers are not affected. Sarah-Jane Gray, Retune Campaign Coordinator for Freeview, said: “Most Freeview viewers are used to retuning every now and again. This retune is needed as part of the technical upgrade to roll out Freeview HD across Yorkshire. We’ll be working with the community to make sure Sheffield viewers are ready for 17 March.” ____________ * Viewers not able to retune on 17 March can do so anytime afterwards. Notes 1. Freeview HD is being rolled out in stages across the UK. The service will launch in spring 2010 for viewers in Leeds and Bradford, served by the Emley Moor transmitter. Other areas of Yorkshire will be able to receive Freeview HD following switchover in 2011 and 2012. 2. Approximately 64,000 homes are estimated to be receiving Freeview services from the Sheffield transmitter.
