Microsoft has confirmed the Xbox One's HDMI pass-through port can connect to Sony's PlayStation 4 and that "... if you wanted to be playing Ryse and Killzone at the same time, you could snap that."



From Neowin:

Earlier this week, Sony announced as part of its Tokyo Game Show presentation that the company would allow for capturing of game video with its HDMI port. This is an interesting move by Sony since it established HDCP copy protection over an HDMI connection in its current PS3 console.

Microsoft has put an HDMI pass-through port in the Xbox One, which allows it to output video from another hardware device. The port was put in primarily to allow Xbox One owners to connect it to a cable TV set top box so they could watch a TV show in snapped mode while also playing a game. Microsoft has also confirmed that the Xbox One will work with external video capture devices.
