-Also in VLC
How does WiSS work?
Server casts a media only to clients who desire
to watch the media
 Every client can be also a server at the same
time
 A client, who is not in a Multicast Group, can
join the Multicast Group at the middle of a
casting session

Future Extension

Java Media Framework (JMF) in RTP
based server-client communication

JMStudio, integrated with WiSS GUI, are used to
open media at the client.
Hardware/Software Requirements
VLC media player
 Java & Java Packages
-DatagramPacket
-DatagramSocket
-MulticastSocket
