IP TV definitions and businees models
BT: Safe delivery of streamed visual content to users via a managed network and itspresentation on a TV set or a similar device
NTT: Digital TV service delivered to users via broadband IP network
TVP: IPTV – any audio/wideo transmission, which even partially is based on the IP protocol (prof. Marek Hołyński)
EIMS 2017 7
What is IPTV ?
• TV in the IP network
• Bidirectional channel between a user and a service provider
