Unicast and Broadcast:
Complementary for Unlimited
Mobile TV
Unicast is communication between
a single sender and a single receiver
over a network. An earlier term,
point-to-point communication,
is similar in meaning to unicast.
Typically, current 3G networks are
unicast, which means that there are
as many mobile TV signals as there
are number of viewers simultane -
ously watching a given program.
By contrast, broadcast is commu -
nication from one sender to all
potential receivers in a given
area/region.
