If you use our service on a Sky box you may notice that every now and then you come across a large "Please Wait" screen.
We put one of these up every time a user selects some content that can't be loaded in a few seconds.
In an ideal world, we wouldn't need them at all - we don't want you to have to wait ten seconds or so just to get to the News Multiscreen. However due to the way our service has to be structured, it's an unfortunate necessity.
The reason for that is all to do with bandwidth and positioning.
Satellite space is broken up into chunks called transponders - the ³ÉÈËÂÛ̳ has seven of these. The main ³ÉÈËÂÛ̳ TV channels are split over six of them, and each contain a series of TV and radio channels - including 18 regional versions of ³ÉÈËÂÛ̳ One and 4 national versions of ³ÉÈËÂÛ̳ Two.
³ÉÈËÂÛ̳ Red Button has a chunk of space on each of those transponders which enables us to have a service alongside the TV channel - so that when you press red you don't need to leave the channel you're watching.
However that chunk of space isn't big enough to contain all our content, so some of our text content sits in a shared area on another transponder. Our video services too also sit in another transponder to the TV channel. When you select some content - like Flight Arrivals, the News Multiscreen or Sport Multiscreen - the set top box needs to retune to the other transponder and load up the content. This can't be done quickly, hence the "Please Wait" screen - which we call an interstitial internally.
As well as promoting various parts of the service, we also use the interstitials for information purposes, like reminding people that the clocks will be going back or forward. And at Christmas, we like to have a little fun, in the form of our advent calendar - running from the first of December through to Christmas Eve.
The follow up on Christmas Day is my personal favourite, however I suspect many people won't actually get to see it - people are generally too busy cooking turkey and opening presents to be pressing their red button. However if you have a spare moment amongst the chaos and mayhem, why not press red and see what you find!
