You can’t discuss communication protocols nowadays without bringing up IMS. Although IMS started as a mobile-centric protocol, it is now all encompassing and also includes IPTV. Since both Packet Cable and TISPAN make use of IMS, IPTV also has an IMS architecture connected to it. IMS for IPTV starts simply from the fact that operators today are mostly triple-play or quad-play players: their services include telephony, television, internet browsing and mobile phones. Quad-play doesn’t mean convergence in any way –

The lines between communication services are getting blurrier every day thanks to the internet.

Developing a videophone or any other telecommunication client? You should start thinking seriously about IMS. Today, there are two main standards used for multimedia communications over IP: SIP and H.323, where SIP is the standard which is being adopted by most vendors today – especially in the consumer market. As 3GPP, 3GPP2, TISPAN, Packet Cable and WiMAX have all selected IMS for their next generation networks, it goes without saying that a lot of vendors will start working on IMS
