The BBC has come under fire for the per­ceived poor pic­ture qual­ity of its high defin­i­tion tele­vi­sion service.

Dani­elle Nagler, the Head of BBC HD, has so far failed to pla­cate crit­ics with her responses to com­ments on the BBC web site. On the BBC pro­gramme Points of View she said “Theres no evid­ence that redu­cing the bitrate has an impact on pic­ture qual­ity, or that there is an abso­lute rela­tion­ship between bitrate and pic­ture quality”.

How­ever, from a recent blog post: “I appre­ci­ate that BBC HD offers us the widest range of pro­gram­ming cur­rently in the UK. But even my wife can see a reduc­tion in pic­ture qual­ity and she’s got cataracts.”
