Brough Turner notes that the most common usage of video phones is “see-what-I-see”:
Note that “see-what-I-see” uses full-duplex voice, but usually only requires half-duplex video.
A common scenario for the business market is showing someone back at base info so they can add value to it and send directions for action out into the field.
Unfortunately, all the 3G networks are back-to-front because they make the downlink faster than the uplink (for technical as well as marketing reasons; the uplink is powered by a weeny battery and teeny DSP in a wobbly mobile box facing a number of difficult coding and timing problems I barely understand, whereas the downlink isn’t).
Apparently you’re supposed to be watching expensive football clips and not making your own videos.
