BT has been pushing to become the destination for sports, fighting back against the BBC and Sky for rights and coverage of some of the biggest sporting competitions. 

One of the first steps was launching BT Sport 4K UHD in 2015, which BT Sport Ultimate replaces, along with the Dolby Atmos sound that it offers to BT TV customers. Added to the mix, BT Sport Ultimate now also offers HDR on multiple platforms and for certain events.

Here then is everything you need to know about the expanded service from BT Sport.

BT Sport Ultimate: Who gets what?

While BT Sport Ultimate is capable of offering 4K, HDR and Dolby Atmos, it's not as simple as everyone getting the same quality.

4K UHD: This is available through the BT Sport app for several devices: Apple TV, Xbox, PS4, Google Chromecast and Samsung TVs are supported. It is also available as part of the BT Sport Ultimate TV channel, formerly known as BT Sport 4K UHD. If you get that from BT TV or another provider, like Virgin Media.

Dolby Atmos: This is exclusive to BT TV customers watching BT Sport Ultimate.

HDR: HDR content is now available on the BT Sport big screen app for Xbox One (S and X), Samsung smart TVs and Google Chromecast Ultra. It is available with 4K on each of those platforms.

HDR is also available through the BT Sport small screen app for iOS and Android smartphones, as long as the hardware supports it. They are restricted to HD streams, however.

What will I need to watch BT Sport Ultimate?

The new channel aims to deliver content at the highest quality it can no matter the platform that you are watching it on (with the exceptions given above).

If you're a BT TV customer, you'll need the BT Ultra HD YouView box to deliver it and if you want the Dolby Atmos sound, you'll need an Atmos compatible TV, soundbar or receiver.

But BT Sport Ultimate also aims to deliver a boosted experience to those using smartphones and tablets, up to the capabilities of those devices and that's where HDR comes in. If you have an HDR compatible phone, for example, BT Sport Ultimate should be able to push that picture quality higher.

Ultimate is also available to those app users on Apple TV, Xbox, PlayStation, and Samsung smart TVs.

What will be on BT Sport Ultimate? 

The line-up of programming for BT Sport Ultimate includes a lot of Premier League football. BT Sport says that "the majority" of its live matches will be on BT Sport Ultimate. 

It has also been showing Champions League and Europa League matches on the channel - with future rounds to follow.

Most are in 4K but only a few are also presented in HDR. Check schedules to find out.

BT also has the rights to Moto GP, Rugby Aviva Premiership and the Ashes in 2020 - but it is less clear which of those will be showing on Ultimate.

How do I get BT Sport Ultimate? 

If you're a BT Sport customer with BT TV and have BT Sport 4K UHD then you already have it. Just head to channel 433 that used to host BT Sport 4K UHD and BT Ultimate is already there, ready to deliver the goods. 

If not, BT has a full range of BT TV packages and BT Sport Ultimate is included in the Max 4K TV package.

Those using the BT Sport app as part of an EE or BT mobile plan, or as part of a BT broadband bundle can upgrade to BT Sport Ultimate for an extra £5 per month.

Also, a new, no-contract BT Sport Monthly Pass, costing £25 for 30-days access to all channels through the BT Sport apps, includes Ultimate.

Virgin Media offers TV access to BT Sport Ultimate. For Virgin Media customers you'll find it on channel 531, but you'll need to subscribe to BT Sport as part of your package. 

For those on Sky, you can access BT Sport and you'll have to do this via the BT website. BT says that Ultimate is coming soon, but there's no precise details yet.
