IPTV (Internet Protocol Television)
Protocols Used for IPTV

In IPTV networks are used standard protocols SIP, SDP, RTP, RTCP, HTTP and DIAMETER for NGN and their combinations [14], [37], [38]. Their performance charts are listed in first section (NGN). Specific protocols IGMP, MLD and FLUTE are used too.

The Internet Group Management Protocol allows hosts or UE to participate in multicasting (by joining the stream) and describes the basic of multicasting IP traffic, including the format of multicast IP addresses, multicast Ethernet encapsulation, and the concept of a host group.

MLD and MLDv2 protocols are designed for use only in IPv6 network. This protocol is follower of IGMP in IPv4 networks used for joining some network node to multicast group. Multicast groups are separated by different IP addresses.

The File deLivery over Unidirectional Transport (FLUTE) protocol (RFC3926) is a protocol for the unidirectional multicast delivery of files over the Internet.
