This side of the pond, some of the on-screen graphics you see on broadcasts is now being rendered in the set-top box/TV, not by the broadcaster (a bit like closed captions can be in the US)
So graphics like "Press Green to Remind me", "Press Green to Record this", "Press Red to singalong" etc. appear on-screen, but are not part of the broadcast video. Instead a data stream accompanying the video service is received and triggers the set-top box or TV to overlay a graphic (designed by the broadcaster) over the video stream. (The idea is that you press a coloured button - Red for interactive TV, Green for Record/Remind - to access optional services)
However you can chose, on some receivers, not to see these icons, and as they aren't part of the video stream, some PVRs/DVRs don't replay them on recordings.
Of course we still have some snipes, end credit promotions etc. - but some of the on-screen junk here is optional.
