BBC cuts HDTV bit-rate

Data rates on Freesat have been ramped down - now below ten megabits per sec for H.264 - this is likely to reflect what Freeview HD will look like when Mux-B gets fired up from Crystal Palace this December.
Danielle Nagler, the recently-appointed head of BBC HD, admitted that the BBC had reduced the HD channel’s bit rate. She claimed that there was no evidence that a reduction in bit-rate reduced the picture quality.

I have to say that if you're the head of HD for probably the most prestigious broadcaster in the world and you believe there is no correlation between bitrate and perceived picture quality then you got the job under false pretenses as you know nothing about the technicalities of DVB.
Why didn't they give me that job! I know pretty much everything about SD, HD, DVB-T, OFDM, QAM etc etc!

It reminds me of the facilities (oh, and Quantel!) that used to claim 8-bits was better than ten!

Reminds me of when they tried to claim no-one could tell the difference between 720 and 1080!
