While Vistium and Picasso require some heavy duty hardware the video
phone only requires compatible phones at both ends of the call. The
phone transmits a 15 fps colour picture along with regular telephone
voice. The phone was not an initial hot item - people complained
about the slow picture updating, but it sure puts CU-SeeMe to shame.
I hadn't thought to compare it to this software, but the comparison is
quite logical. While not being an expert on either system I would
imagine the faster (and colour) picture is due, in part, to hardware
based compression.
