KT-Tech Challenges Nancy and MPEG-4 for Wireless Video
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?"
Admittedly the Japanese are a very tech-gadgety type people, but here in Japan newer cellular phones have still cameras on them and people love them, they're pretty popular, so that kinda answer the poster's rhetorical question. I can only imagine that moving cameras will be even more popular. All modern cell phones here have beautiful color displays, and it's pretty sweet being able to take a picture of something with your cell phone and then send it to your friend's cell phone where it can be instantly viewed. Not necessarily super useful but pretty fun, especially among the younger set.
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.
J-Phone in Japan already has camera phones. Right now you can only take still pictures though. Here is the phone I got. I just wish I could use it in the US.
