BT TV multicast network Currently 18 D plus 4 HD channels 150 Mbps to each fibre cabinet to deliver channels Enhancing the proposition later this year upgrading to 500 Mbps to each fibre cabinet to deliver additional channels 11
BT TV multicast network Multicast on YouView requires a different encryption than delivery on legacy Vision platform imulcrypt allows BT to transmit channels once but encrypt with two keys avoids cost of retransmitting channels twice 12
IT Platforms summary Matrix portfolio architecture used applications aligned into functional platforms functionality grouped into stacks for each customer-facing unit Mixed use of off-the-shelf products (e.g. Oracle) and inhouse Opportunity for further improvements simplify application estate reduce number of UK data centres significant virtualisation opportunity 13
