IBB
• Broadcaster distribution strategy must be hybrid!• Linear TV alone won’t captivate consumers• Seamless Linear TV + OTT is the mid-term future
Use Broadcast as portal to Broadband

DVB-I
• Delivery of DVB services over the Internet (OTT), with similar user experience to DVB terrestrial, cable, satellite and IPTV systems.
• The services will be discovered and consumed by devices with basic Internet connectivity, principally a non-managed broadband connection and HTTP access.
Ensure broadcasters prominence on broadband networks
