of disability benefits did not lose their television services when analogue transmissions were switched off. Another issue was that the "98.5 per cent of the population" availability target could only be achieved "via rooftop aerials", while Section 134 of the Communications Act 2003 sets out the principle "that no person should unreasonably be denied access to an electronic communications network or to electronic communications services". This is taken to mean that everyone has the right to mount a television aerial on their roof. Ofcom allocated frequencies for groups of households to provide "self-help" relay transmitters at their own expense (for analogue broadcasts there were some 200 of these, serving around 13,000 households), but suggested that in such cases, terrestrial TV may no longer be the most cost-effective solution. The switchover process After several months of press publicity, leaflet drops, public meetings etc., captions started appearing on analogue broadcasts from the affected transmitters, warning viewers that the analogue service would shortly be switched off and that they would need to take action (for Whitehaven, the first large area to switch over, the captions started appearing some 5 months before the BBC Two analogue service was switched off). At about the same time, details of the Switchover Help Scheme were distributed. Although viewers who lived outside existing Freeview reception areas were unable to test any digital receiving equipment they had bought at this early stage, test-screens on Ceefax (BBC One & Two) and Teletext (ITV & C4/S4C) page 284 made it possible to determine whether they were likely to need a new aerial or a signal amplifier to receive digital transmissions. Next, detailed information booklets were delivered to all households in the area (including many on the fringe who may have been receiving their TV from other transmitters- hence the importance of the on-screen warning captions). Two or three months later, the first stage of the switchover began with the analogue BBC Two replaced with the new BBC A multiplex. At some locations, during the period between stage one and stage two, BBC One, ITV or Channel 4 moved to the analogue BBC Two frequency where that channel's frequency was required for the digital transmission of Multiplex 1. At the same time, captions appeared on the remaining analogue channels reminding viewers of the impending switchover. Finally, the second stage saw the remaining analogue transmissions switched off and the other high power multiplexes
