"...

4 mbps to 14.4 mbps but this is updated every second, so
the range of individual frame bit rates would be even wider.

Czyli od 4 Mbps to 14.4 Mbps. BBC HD mialo nawet sredni
strumien bitowy "from 20mbps at launch to just 6.6mbps
(Oct 2010)", zaledwie 6,6 Mbps.

Oraz:
"... it's currently around 9mbps average, VBR ranging from 5
to 14 mbps (and occasionally peaking even higher on action
scenes) ..."

Czyli aktualnie 5 ... 14 Mbps, srednio ~9 Mbps.
