Here comes an interesting article about something that we were nagging Microsoft employees at various trade shows and conference for many years already:

Is your article ignoring MS Portrait? I was able to video conference with this using a plug in camera and the XV6600 almost 2 years ago.

Why is it Microsoft has to provide all of the software for everyone? Are there no more entrepeneurs? Wouldn't MS be accused of monopoly practices if they tried to corner the market on every category of software for their systems?

MS Portrait uses SIP as the protocol of choice, which runs over IP and requires WiFi (or HSDPA in the near future) on the mobile phone. Although it is cool, it just doesn't work in real life scenarios.
3G video calling is done using 3G-324M, which is a circuit switched protocol running over UMTS network, available in most 3G phones today.
Doing 3G-324M is not easy, and this is what my article comes to elaborate. RADVISION provides this technology along with specific tailoring to customers for Windows Mobile when the customer needs it, but this is by far not an easy task.
As 3G-324M becomes almost mandatory for handset manufacturers that actually want to sell their handsets through operators in Europe and in Asia, the lack of it in Windows Mobile hinders this platform and its appeal to manufacturers.
Assuming Microsoft decides to implement it, it will make the life of many handset manufacturers a lot easier...

| I think the main reason there is no MS made video calling application is simple; nobody would use it. I mean, who here actually makes 3G video calls on a regular basis (and I don't mean drunken calls to your mates). |

Exactly! How many people did non-video calling in 2G using the speakerphone in public places? And how long can you keep your phone in your hand in front of you face? I don't know about others, but my hand gets tired. If you need some cradle and the phone must be on a table then it's no more a mobile phone.

No doubt - current solutions are cranky at best in terms of the user's experience. The fact that you raised this issue simply means that developers need to put more effort in making sure their handsets actually work good with video. The article comes to discuss exactly that from the technical point of view of software development.
Same question can be posed about mobile TV and MMS, but video seems to be an important enabler for new services in mobile networks.
I think the main question is not if video will catch in mobile handsets, and will people use it. The question seems to me more when will this happen, and for which kinds of initial services?
Is it going to be for watching TV series? video blogs? your family? friends in a trip? security cameras in your home? some other service we don't quite grasp at the moment?

Obviously, you (and others) haven't the need to teleconference on a mobile basis. Many businesses outfit their employees/consultants to do just that via 3G-enabled cells which incorporate a VGA camera. Video-enabled cells, clipped to notebooks, are used the same way. Why do you think webcams for notebooks are necessary for business? Mind you, I said 'necessary', not 'desired' or 'used'. A segment of the market which is large enough for manufacturers to respond to demands it. Just because you, personally, cannot relate to it doesn't mean a legitimate demand isn't there. |

I find the whole subject of video calling an interesting one....after all who actually uses it ?
I live in the centre of a busy city and if i walk down the street i see people young and old clutching mobiles to their ears, just about everyone from the age of 10 years upwards has a cellphone.
That said i've yet to witness anybody actually making a video call. Perhaps they do in the privacy of their own homes but outside i,ve never spotted anyone.
I don't know about the rest of the world but here in the UK generally it costs more to make a video call, although one network provider i know of includes such calls in their airtime at no extra charge.
It's not really very practical to take or make video calls when you're on the move, and inconvienient to stop whatever you're doing and hold a cellphone up to your face so you can be seen by the person you're communicating with.
I think the idea of being able to actually see the person you're in conversation with is great, it's Sci-Fi come true but do the masses really care ? |

Do you have an example of such a business?
I'd be interested in checking it out; would be cool to know more about the line of business that really uses or even needs video-calls on a regular basis. |

Not in my personal experience.
Would be a nice development in the future, but we're quite quite a way off from implementing something like this.
Only thing I've heard of so far is video-conferencing with specialists in a certain field who live too far away to just pop over for a consult.
I can see good use in telephone consults with a GP for something like skin problems in the future, though.
You can ask the GP whether you should come in just by showing him the problem. |

What you speak of is direct medical care. The Medical industry is much more diverse and complicated than that narrow, simplistic view. Never heard of telemedicine, eh? It's no longer innovative and considered old-school today. Cadaver labs who broadcast newly developed surgical techniques worldwide with direct/immediate input from those 'viewing' the case is a bit more current, but still not today's cutting-edge.  |

HTC has licensed all imaging applications like MMS editor from ArcSoft (and they suck). Both HTC and Palm can license 3G video calling as well. It's not too expensive for Palm. I wouldn't be surprised if Palm users don't need 3G video calling.
Usually companies do not develop this kind of applications themselves. They either license them or buy some company, which has the application. I'm sure there is a company who develops a 3G video calling application for Windows Mobile or one that is easily ported to WM.

Yes, and you're about to tell me where teleconferencing on a mobile basis figures into this, are you?
The applications you talk about are hardly implemented widely by landline, let alone based on teleconferencing on a mobile basis.
Why do you have to take an antagonistic tone again? |

Well, there are companies who develop it. My article was specifically after my company (RADVISION) did this exact kind of work for a customer (who is by the way in the article as well). It is not as easy as it seems, and it is not easy to copy to other platforms. The exact issue of which codecs exist on the platform, which kind of CPUs are used, does the platform has a hardware accelerator for the codecs, and other such questions make sure the work cannot be easily copied to other platforms.
