1146 Multicast Commands
• Applications used for datacasting: Since multimedia transmission has
become increasingly popular, multicast transmission use has increased.
Multicast transmission may be used to efficiently accommodate this type
of communication. For instance, the audio and video signals are captured,
compressed and transmitted to a group of receiving stations. Instead of
using a set of point-to-point connections between the participating nodes,
multicasting can be used for distribution of the multimedia data to the
receivers. The participating stations are free to join or leave an audio-cast
or a video-cast as needed. The variable membership maintenance is
managed efficiently through multicasting.
