KT-Tech Challenges Nancy and MPEG-4 for Wireless Video 134
Robert Gallagher writes: "Last week, at http://www.kttech.com/comp.html, KT-Tech released a demo of their video codec running at 32 Kbps. According to the web page and discussion on comp.compression, this codec is 'symmetric,' meaning encoding is just as fast as decoding, and that both can be done in software and in real-time. While Nancy is getting good press for its light decoding cost, KT-Tech is apparently trying to get into the two-way wireless communication market. One question to ponder: Would we really want cameras on our cell-phones?"

For example, I take a trip to Seattle. Back home my girlfriend "calls" me, and I let her share my senses. The advanced technology allows her an immersive experience... she sees the skyscrapers, hears cars below, smells the funnel cakes, feels the wind blowing while I'm looking out from the observation deck of the Space Needle. And she doesn't have to be there.
Obviously it's all vaporware today. But each step takes us closer to the goal. Even if it is a commercial failure, we still need to take these steps.
Or are my expecations of the future too great?

On the other hand, this could actually reduce some of the problems of cell-phone use while driving. Cell-phones are disorienting because they are a disembodied voice, and if your mind tries to compensate by generating a mental picture, you become less aware of your surroundings. If you have a picture to tie to the voice, then your mind might not have to separate from where your body is as much.

No problem with licensing as far as the hardware is concerned - it's just part of the cost of the phone. But now if you want to integrate it in, say, a universal instant messaging framework, the licensing fees become crippling, and for most of the world, the technology is withheld from them for an additional 17 years! Now, weren't patents supposed to benefit the public?

And NTT DoCoMo's quasi-3G service (FOMA) has full bidirectional motion video, so that addresses the original post more directly. Quality could be better, but they are those video phones you always see in sci-fi, and mobile to boot......main thing that's keeping adoption low is that at the moment their service is only available in the Tokyo region last time I checked. Maybe since then they've added a few more regions, but service is pretty limited still. But I recall reading an article about how DoCoMo was surprised by how large demand was still, with it surpassing their initial estimates, so I guess adoption on those is going just fine too. Right now it's mainly geared at businesses, with the hype surrounding applications like using the camera to show progress at the work site to be people back at the office and things like that, but as price comes down, obviously it will become more mainstream.
