Multimedia Messenger Function List 박성민

Multimedia Communication Funcs Sup port Call & Conference # of Simultaneous User supported  Voice, Video, Voice + video Dynamic change of encoding Joining to the multiple conference Multiple conversation (voice, video)  Simple on/off switch to send data (while receiving the peer’s data) Voice Mixing by host Playing Recorded AV Security Data Encryption Differential Profile exposure Encoding Fixed encoding by user preference or initial setup Dynamic change of encoding Silence Suppression ( no movement detection )

Contact List Management Funcs Sup port Contact list Buddy list, Grouping  Distinct status, ringing, reply Buddy Status Subscription / Notification

Proxy & Location server Funcs Sup port Proxy Server Differential Reaction  Distinctive Ringing – proxy  Distinctive contact reply – proxy or end Location server (Registar Server) user search based on the profile sharing Buddy Status Subscription / Notification

Etc Funcs. sup port BGM Playing local media and mix Contact list share/save Provide a certain format of contact list ( e.g xml as in MSN) Application sharing White board or music box Recording Voice only? Firewall using UPnP NAT NAT resolution with STUN Req

Cautions P2P overlay Network  Each SIP workhorses should be able to be operated in separate intranets independently Should a Super-node be a proxy, registar?
