ok- I keep hearing everyone say "ATT's network would collapse" and what not if iChat were enabled. But here is the thing- how much data bandwidth would it really take up? Right now, the 3g allows simultaneous data and voice. So we have the existing voice network handle the audio part of the ichat. Then we are just left with video: forget 30 fps- maybe 15 at most, probably more like 10- even if the network is perfect. So we have 10 fps on a screen with a resolution of 320 by 480- but the incoming video stream would not be that high- it would probably be displayed less than that- so lets say 200 wide by 150 high- ok so now we have 200 by 150 video at 15 fps. We are talking postage stamp video resolution of 1996 when real player first hit- but because its on a phone its way cool. Not to mention compression and hardware decoding will make the stream smaller. And- heck the resolution of the video being taken could be 2/3 that and interpolated up to that. Sure it would look like crap on a full screen chat on a mac desktop- but who cares? We would have working ichat video on a cell phone. Also- ichat for the mac would be updated to identify people on iphones and change the outgoing stream resolution and compression for them to accommodate their phones picking it up. thoughts anyone?
