Sky is ready to revamp its EPG in what the satellite broadcaster is calling "one of the biggest updates to the channel line up for over a decade".

The move sees HD customers getting their 1080i (or 720p) fix on the original "high-profile" channels (i.e. the original ones) - which is a bummer really as we'd just about memorised the HD line-up. Oh well...

So, if you're a Sky+HD subscriber, 40 channels in your HD pack will switch positions in the line-up with the SD versions.

If you're not a HD subscriber, don't panic - you won't have to learn new numbers as your SD channels will stay where they are.

There's also a bit of shuffle down the pack as well (SD or HD versions, depending on you package):

Comedy Central moves to 112, Universal moves to 113, Syfy will be on 114, FX jumps to 124 and MTV moves away from the music bunch and will be found at 126.

Sky Atlantic will launch onto channel 108 and Living will re-brand as Sky Living and will move to channel 107.

Rob Webster, Sky’s commercial director, said: “We want our customers to be able to discover and enjoy the content they are most passionate about. That’s why we’ve worked with a range of partner channels to ensure that customers can find their favourite pay TV channels and programming as easily as possible. 

"And with high definition viewing now demanded as standard, this has also meant swapping HD channels into the EPG numbers that our customers know best.     

"The combination of high quality content, an intuitive, easy-to-use EPG, and innovative services like Sky+HD and Sky Anytime+, means our customers benefit from real choice, control and flexibility of viewing, whether linear or on-demand".

The changes take effect from 1 February.
