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.”
