There is often confusion between webcast and videoconference terminology as they appear to use similar technologies to communicate/work at a distance. The principle difference is that video conferencing is designed to allow two-way communication between distant locations (many-to-many), where as webcasting is a primarily broadcast medium, (in one direction, one-to-many). Videoconference work requires low latency and is technically challenging to scale beyond a few participants. Webcasting with it’s one to many design can more readily scale limited only by available bandwidth.

Video conferencing best serves remote meetings with a small number of active participants, and where bi-directional communication is essential. Webcasting is ideally for events such as presentations, lecturers, or anything that might be on TV or radio, and can leverage similar methods as TV and radio use for getting a small element of remote audience participation.
