BBC 4 HD, & Cbeebies HD to move to PSB3

[Keith]

Would be very difficult to explain to the public which boxes and TV would stop working and what ones won’t.

Not really, in my opinion. Simply "Do you have Freeview and are you able to watch BBC One HD on channel 101?". If yes to the first part and no to the second, then you'll be affected.

In short we need to ditch DVB-T and MPEG 2 ASAP

That's millions of set top boxes and televisions you're consigning to the scrap heap though... on top of the millions more already scrapped at DSO. Not very environmentally efficient.

I suspect the number of devices aren't affected aren't as high as five years ago. Also they could do it one multiplex at a time, and leave PSB1 and PSB2 unconverted using DVB-T to allow those with older devices some channels.
