Xbox One owners across the UK are reporting a “juddering” picture when using the Xbox One’s TV integration. The problem occurs when a feed from a set-top box, such as a Sky or Virgin Media box, is input via the HDMI-in port.
The source of the problem seems to be that the UK and Europe use a 50Hz broadcasting system whilst the Xbox One runs at 60Hz – the system favoured in the US and Canada.
“Assuming the reports are true, this represents a significant issue Microsoft has to address”, said Digital Foundry’s Richard Leadbetter. “Displaying 50Hz video at 60Hz means that every sixth frame will be a duplicate, resulting in noticeable judder on a lot of material – scrolling text on news channels, fast pans in TV and movies, and the left to right sweep of the camera in football matches.”
“We haven’t been able to figure out why different people on different Sky+HD boxes with the same settings get different experiences though,” posts Studbucket, “We’ve even dispatched devs to home and couldn’t figure out what was going on. We’re definitely aware of the issues though and working on them.”
“There are no easy solutions in this scenario – the kind of frame-rate upscaling required to eliminate the judder at 60Hz would probably compromise image quality,” explained Leadbetter.
“The simpler solution would be to lock the user interface to 50Hz when TV elements are on-screen, switching back to 60Hz for gameplay – though this wouldn’t be quite as seamless an experience as Microsoft originally envisaged.”
