Re: Ofcom .. concluding that it would be unfair to make the UK’s then 4.6 million receivers obsolete
DAB has one inherent flaw that digital terrestrial TV didn't, the cost to consumers to upgrade.
Bad UI compared to Analogue Radio. (DTT has identical or better UI than Analogue TV)
Bad Coverage for portable
Much much poorer compression vs Analogue Audio compared to Video
DTT does WS and HD (not on Analogue Video)
No significant power difference on Analogue Vs Digital TV as screen backlight (or CRT or projector) is most of the power.
Little TV usage is portable. Much Radio usage is portable.
Radio is used with HiFi, (DAB isn't), transportable table sets, for Foreign Radio (DAB is local/National only), Mobile and Portable. DAB useless for Portable.
DAB isn't suitable for Local or Comunity, the MUX areas are far too large, yet are full of holes.
No gradual degradation when moving into poor reception, But DAB cuts out and can't restart till buffer active.
Massive x20 power consumption for Headphones, Only acceptable in car or mains.
DAB isn't an AM/FM replacement. Perhaps no Digital Radio can replace the unique properties of Analogue Radio easily.
