BBC 4 HD, & Cbeebies HD to move to PSB3

However MPEG 2 (which is used for most Freeview SD channels) is a coding system from the 1980s, and is not very bandwidth efficient,

Late 90's, surely? And MPEG2 encoders continue to improve even today, squeezing more channels into less bandwidth than ever before.

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.
