Virgin then remultiplex the services into their own transport streams and finally add in the Nagra encryption.
When NDS updated Sky's encryption, ntl had to put new software on the 5020's, and on each of the CAM's within the 5020's. ntl also had to update the software on all the TT1220's and the 3000 series IRD's in the regional headends around the country which provide the analogue cable feeds of Sky channels.
Any of the Headend Techs working in 2003 should remember the upgrade of the IRD's and ringing Sky to get the new Sky cards enabled!

as i said a few pages back VM get the channels from Sky & rebroadcast them on their network.
