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
