US makes slow progress to all-digital

Chris Forrester

June 12 saw the USA switch off its analogue TV signals for its major broadcasters. Audience measurement specialists Nielsen says some 400,000 homes have since bought either new TVs or converter boxes. But this still leaves a huge number of u unserved homes.

Nielsen says that despite the advertising blitz they estimate that 2.1m TV homes (or 1.8% of the nation's TV households) are without digital TV.

Added to this already high number are a number of homes that have signal problems, with aerials, signal propagation or power interference issues because of VHF stations (some of which remain on air).

The FCC is working to resolve the VHF problems, in what they describe as "mop up" tasks following the analogue switch-off process.
