The craft of making Being Human and Later With Jools Holland in High Definition TV

As any of you who has bought a High Definition (HD) television - or just read the claims about them - will know, HD can give you five times more detail in your television picture.

Most of us don't watch standard definition TV and notice the absence of all that detail, but it is true that watching HD pictures can show you things on television you have never seen before (and may not want to).

When HD television first started, ripples of terror ran through the communities of people who help make the television illusion real for us - the make up artists, set designers, costume designers, props people, and so on.

But they are, of course, highly skilled craftspeople, and have learnt to understand HD and to adapt the ways they work to suit.

We wanted to show you a little more of what HD involves and to share with you the talents of some of those who make it all possible. So we've made a series of short films to give you some insight into how programmes are made in high definition.

They'll be shown on TV in some of the gaps between programmes on BBC HD - and available on the BBC website - but I wanted to share the first two with you here.

They take you to visit the model makers at Aardman in Bristol who care for CBBC'sShaun The Sheep (I'll update this post with a link to this video when it becomes available) and the make-up artists who spend hours creating werewolf wounds on BBC Three'sBeing Human, as well as the sound engineers responsible for the full (5.1) musical experience on Later with Jools.

I hope they help you to appreciate the often unsung heroes who make HD TV work for the BBC, and for you.
