H.263+ and wavelet encoding are providing better video as well as better error tolerance.

Lucent AVP III is one of several high performance codec chips that relieve the host computer of these computationally intensive tasks.

HP PA-RISC 8200, Pentium II, etc., with their higher computation capabilities are able to run software codecs at useful speeds.

100baseT, Gigabit Ethernet all provide the network pipeline head room necessary for the addition of video conferencing payloads.

CCD, CMOS, USB, Firewire - all of these technologies are enabling vendors to come up with better, smaller and cheaper cameras.
