It has AR foreground graphics and virtual screens which are keyed over Olympic ring physical set elements (so disappear when not in-use rather than remaining with a holding graphic in them as a physical screen would) However the year also using the jib tracking data for generating content for the large LED 'wraparound' screen behind the hosts and presenters. (This AR is very similar to the treatment that BBC Sport used in Rio.)
This LED screen has content that is tracked to the jib so it gives huge depth and parallax - as the jib cranes up and tilts down, or tracks the LED content changes perfectly locked to it (I think they are taking a 4K beauty shot a lot of the time). They then have overlaid 'frosted window' effects that are also in the LED screen overlaid over the tracking background. The result is incredibly effective. (This is a similar technique to that used on the projector graphics that the BBC used on the Scottish Referendum results.)
