Andy Quested is BBC HD's Principal Technologist and seems to be not just incredibly switched on but also remarkably candid when talking about the challenges facing the channel.
As regular readers of this blog are all too aware, there's been a lot of criticism both here and elsewhere of the picture quality on the channel since the bit-rate and encoder changes in August. Mr Quested has been mostly silent on the matter, but his long-promised blog posts are now to appear daily as he presents his Hitchhiker's Guide to Encoding that will hopefully answer a number of questions. Here's what he has on the menu - links will be added as the posts appear.
Friday: Opening and audio issues
Monday: HD encoder history
Tuesday: The EBU
Wednesday: PSNR and all that
Thursday: New encoder evaluation
Friday: Programme styles and closing thoughts
