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 -

I have started this IPTV series with a rant that current IPTV features are not enough. It is time I outline the list of applications for my future TV. Some of them are going to be related with connectivity while others with hard-core technology requirements. I will be skipping the usual suspects of VOD and EPG and assume they simply exist. Here’s the list of the application I’d really like to see in my future TV. 1. Video Telephony

There’s no presence in TelePresence. And you know what? There’s also no “unified” or “communication” in UC (Unified Communication). These are just new buzzwords in VoIP town. They are there to replace “video conferencing” and “convergence.” Besides the fact that they are more of the same (maybe better), there’s nothing new under the sun. TelePresence TelePresence is simply better video conferencing. It has higher resolutions (1080p instead of 720p, or CIF if you refer to legacy systems), higher bitrates and

Two weeks ago, RADVISION hosted the IMTC SuperOp! 2008 event. The most obvious conclusion from this event is that multimedia conferencing (or should I say Unified Communications) is getting better – at least in terms of interoperability. Without exceptions, all companies successfully connected video sessions with one another. The IMTC SuperOp! event is the main interoperability event of the IMTC. In this event multiple activity groups, each dealing with a different multimedia communications technology, gather in a single room to
