Until video becomes personal
March 22, 2007
When you are at such an exciting technology conference as VON is, of course the desire is to see and hear every talk – and of course, it doesn’t work like this, especially considering RADVISION booth duties and IMTC promotion and networking. But I was very happy that I managed to attend Zohar Zisapel talk about video. Zohar is RADVISION Chairman of the Board, and a Video over IP industry veteran.
I really liked what I heard, probably because it resonated so much with my own perspective on the real-time Video. Just to reflect back, I had startling moment at IMTC Fall Forum 2001 in Seattle, where Rich Baker, one of the PictureTel founders, said the following: “in the enterprise, Video is not mission-critical application, and voice and e-mail are”. This was something I never realized before, and from that moment on, I kept repeating that sentiment almost as a mantra.
Enterprises don’t have compelling reason to put video on every desktop… until video becomes personal. Until people will be able to use video to connect to their families and friends, there will be no driving force behind video on every desktop. And this is what Zohar was talking about and vividly demonstrating with a number of excellent video clips. The ubiquitous video connectivity is becoming part of our daily life (well, not necessarily in US, yet).
With advent of 3G mobile telephony the ability to see your kids at any time, and to witness remote events, and to conduct business meetings from the beach is simply priceless. And as Zohar pointed out, video does worth a thousand words, as he clearly demonstrated with last clip in his presentation, showing a number of short silent video fragments, which were delivering very powerful emotions.
And then there was only one question coming from the audience (and that was the question I was expecting to hear) – when 3G will come to US. Well, nobody was able to answer that question, but with all the new phones, supporting Wi-Fi, 3G and EVDO, my hopes are really high that even US will come out from the stone cellular age. Now, we just need to ensure all those technologies are interoperable…
You’ve probably already heard about IMS (and no, I am not referring to the Institute of Mathematical Statistics), and if you haven’t it’s about time!
In a way, IMS is all we ever wanted out of a communication system but were always afraid to ask for. It can handle services – intelligent ones, which traverse through several, different application servers. It can do billing. It is flexible. But it is also complex. Very complex. And at the heart of it there’s SIP – the text-based VoIP signaling protocol.
In its present state, IMS requires a large set of protocols. For SIP alone you will need SigComp, and Offer-Answer model, and Preconditions and P-headers, and new authentication and authorization mechanisms. And that’s not all. Since this requires a huge amount of work, the industry has come up with a new term for “wannabe IMS” companies that are currently deploying SIP and want to migrate to IMS: “IMS-ready.” By calling their products “IMS-ready,” what are they really trying to tell us? “Well, I have SIP, and I really want to do IMS… and since SIP is part of IMS, I am ‘IMS-ready.’” This means that sometime in the future they will get around to developing all those nasty IMS components that are missing.
If you think that this is all there is to it, then you’re quite wrong! If you have an IMS-compliant (NOT “IMS-ready”) solution on a SIP IMS User Agent (that’s a client), you also have a lot of applications running there. These can be VoIP, Video over IP, PoC (Push-to-X), Presence, Instant Messaging and maybe more. Each one of these is a world of its own, with a set of rules that are specifically tied to large number of standards – some of which are not even finalized! So your world as a client developer is a rather challenging one indeed!
How can a frazzled client developer possibly stay on top of all this? You can join the IMTC IMS Activity Group – a new “home away from home” especially for IMS client developers.
For years, the IMTC has been working on interoperability of multimedia technologies. I have been a part of this myself, as a co-chairman of the 3G-324M AG (Activity Group) for several years – in the good old days when video on 3G handsets was only in its infancy. Our 3G-324M AG has done some great things, and we still are, making sure that new handsets can talk to one another with video over circuit switched connections.
Now the IMTC has decided to open a new Activity Group to deal specifically with IMS interoperability issues on the client side – to help all those mobile handsets, wireless PDAs and wireline phones that want to be IMS clients. Not “IMS-ready” – IMS-compliant.
The bottom line: If you are doing IMS, and you are developing clients, the IMS AG, is the place for you. I’m the co-chairman and I can tell you that companies like Ericsson, Nokia, Sony Ericsson and Samsung are already there. So come and join us!
