Sky has a new trick for cutting the delay on live sport, and the timing is not subtle. With the World Cup about to kick off, Sky is rolling out Real Time, a feature for Sky Glass and Sky Stream that finally shrinks the gap between what is happening on the pitch and what you see on screen.
The World Cup is being shown on the BBC and ITV, both free to air. Real Time works on those channels through Sky’s platform, which means that if you are watching on a Sky Glass TV or a Sky Stream box, the BBC and ITV feeds could reach you faster than they would if you opened BBC iPlayer or ITVX directly.
It’s not all perfect, though, and there are a few caveats.
What Real Time actually does
Streaming has a built-in disadvantage when it comes to live telly: it is slower than a traditional aerial or satellite signal.
Where someone watching through Sky Q sees a goal within about 8-10 seconds of it happening, a stream can lag 30 to 40 seconds behind. That is plenty of time for a neighbour’s cheer, or a phone notification, to spoil the moment before you have even seen it.
Sky first tackled this back in 2024 with a feature called Live Sync, which cut the delay on Sky Sports Main Event. Real Time is the same idea, now under a new name and pushed further.
It covers select live sports, and for the tournament, it is switched on for the World Cup coverage on BBC and ITV.
When you are watching a supported channel, a Real Time option appears on screen, and selecting it switches you to the lower-latency version.
Sky says it delivers its lowest-latency streaming yet, though it has not actually put a number on how many seconds you will save.
Faster on Sky than on iPlayer?
The World Cup is free on the BBC and ITV, so you do not need Sky to watch it. But if you do have a Sky Glass or Sky Stream, watching those same BBC and ITV channels through Sky, with Real Time on, looks set to give you less lag than opening BBC iPlayer or ITVX on another device.
That is a slightly odd situation: the free broadcasters’ own apps potentially being beaten on speed by a third party carrying their channels.
It also points to why Sky can do this at all. Because it controls both the software and the hardware, the Glass TV or the Stream box, it can fine-tune the whole chain.
The BBC has been working on the same problem for iPlayer, but it has to cope with hundreds of different TVs and devices it has no control over.
When the BBC published the results of its own low-latency trial this year, the gist was that it works well on the best equipment but is not yet reliable enough to turn on for everyone. Sky, dealing only with its own boxes, does not run into that.
The catch
A couple of things to be aware of before you switch it on, neither of them too serious.
First, Real Time asks more of your broadband. Sky recommends 40Mbps for it, against 25Mbps for standard HD and 30Mbps for UHD. If your connection is patchy, the lower-latency stream is more likely to stutter, because there is less of a buffer to fall back on.
Second, and this is the one most people will actually notice: you cannot rewind live TV while Real Time is on.
So if you want to jump back and rewatch a goal, you will need to come out of Real Time first. For a feature built around live sport, that is a slightly awkward limitation, if an understandable one.
For most people on decent broadband who just want the match closer to live, though, it is a simple win.
How to turn it on
There are two things to understand here. The first is that Real Time is not simply baked into the normal BBC and ITV channels you already watch on Sky.
You either tap the Real Time option when it pops up on screen during a supported match, or you tune to a separate, dedicated version of the channel in the guide.
Those dedicated channels sit higher up the EPG and are marked “RT” for Real Time.
ITV1 is on channel 945 and ITV4 on 946.
BBC One and BBC Two also have Real Time versions, though the BBC One numbers run across a block from 926 to 944 depending on your region, since each regional variant gets its own.
So it is worth finding the right one for your area before kick-off rather than hunting for it mid-match.
The second thing is that this is not switched on for everything. Real Time is currently limited to select live sports, and for now that means the World Cup coverage on the BBC and ITV.
It is not an option across every sport on those broadcasters, and it is not on every Sky Sports channel either. If you tune to a random fixture expecting the lower-latency feed, you may not find it.
That will almost certainly broaden over time. Sky has been steadily deepening its commitment to live sport, including a recent deal that keeps Formula 1 on Sky Sports until 2034, so it makes sense for the company to extend a feature like this across more of its sports coverage as the technology proves itself.
For this summer, though, treat it as a World Cup feature first and foremost.
Sky is also running 20% off Sky Glass Gen 2 and Sky Glass Air until June 17, aimed at people upgrading before the tournament, though as always, any Sky hardware deal is worth weighing against the two-year contract that comes with it.
