Sky is rumoured to launch a 4K set-top box this spring. According to the Telegraph, the broadcaster is bringing the launch forward to counter the threat from BT Sport.
BT will have a monopoly on live rights to Champions League matches from next season. Sky wants to parry that with the incentive of a new box for new customers, industry sources claim.
As well as 4K, which has four times as many pixels as standard high definition, the box will have new multiscreen options that let you watch on your phone and tablet (presumably this will differ from Sky Go.) You'll also be able to access your recorded programmes wherever you are.
It's thought the box was originally slated to launch next year.
BT is also rumoured to be readying 4K for BT Sport. It's tipped to launch alongside the company's new set-top box also in the spring.
Expect the telly wars to heat up along with the weather.
4K TVs are still more expensive that standard high definition models, though prices are coming down.
