Video broadcasting utilizes network-friendly IP Multicast to send one stream of data per program to an unlimited number of simultaneous viewers and is appropriate for larger audiences. Video on demand (VOD) provides audiences the ability to access programs, which are pre-recorded and archived. A separate stream of data per program is required per viewer. Video conferencing is a scenario that allows individuals to actually view materials and collaborate in real time with one another at different locations with dedicated hardware over a bandwidth-intensive network. Streaming is an efficient form of video broadcasting that can reach a potentially unlimited audience size and is highly scalable. It is an “anytime and anywhere” scenario which can support all three models of video distribution described above.
