MCS 3.0 architecture :
Multimedia Conferencing SystemMultimedia Conferencing System
The entities of MCS are :
• The Client entity
•The Conference Server entity
•The MLIC entity
•The Compression entity
Multimedia Conferencing SystemMultimedia Conferencing System
The Client entity performs :
•Multimedia captures
•Multimedia playback
•Data packetization & reconstruction
•Communication to server to maintain the RSW control criteria.

Multimedia Conferencing System Multimedia Conferencing System
The MLIC entityMLIC in active site LAN will :
•Listen to specified ports for Audio/Video packets
•Change to Audio/Video UDP unicast and transmit out.
MLIC in the destination LAN does:
•Data packetization & reconstruction
•Communication to server to maintain the RSW control criteria.

The MLIC in MCS architecture :
Multimedia Conferencing SystemMultimedia Conferencing SystemThe Server entity•Control the conferencing using the RSW control
criteria chosen
•To allow users to login into the system
•To reflect the document conferencing TCP/IP packets to all participants.
•Establish inter-server links (during multi server conferences).

Multimedia Conferencing SystemMultimedia Conferencing SystemData Compression (DC) entity •Detect Audio/Video UDP unicast at the MLIC
interface.
•Compress Audio/Video data and transmit via router interface.
•Receive compressed Audio/Video UDP unicast from router interface.
•Uncompress Audio/Video data and transmit via LAN interface.
• All other miscellaneous network packets arriving at both interfaces are transparently forwarded to the opposite interface
Multimedia Conferencing SystemMultimedia Conferencing SystemThe DC provides :
Implementation of any types of compression algorithm :
• H.261• H.320• MJPEG• YUV411
