Only for the "stay" alive signal.
The thing is that Sky makes money on selling EPG positions as the higher a channel is positioned on an EPG slot the more viewers it will attract = more advertising revenue.
So, this means that Sky doesn't want the consumer to be able to choose themselves how and where to position the channels as per the listings set by Sky. One way of doing this is to make sure that the card is "married" to the box that sky has sold (or given) to you and receives an updating signal once in a while. If you take out your sky card for a prolonged time you will see that none of the channels clears but leaving the card in the correct sky digibox/Sky+/Sky+HD box for up to 24 hours (usually 15 min) the signal will update your card and viewing is again possible.
One interesting thing is that if you use a DB (Dream Box) and stop paying for your subscription, you will be able to continue to watch most of the channels for a period after you ended your subscription as the "kill" signal can't be applied. Of course the update signal will be missed at some point and all is gone...
