MULTIMEDIA COMMUNICATIONS

• THE FIELD REFFERING TO THE
• REPRESENTATION ,
• STORAGE / RETRIEVAL
• DISSEMINATION
• OF MACHINE-PROCESSABLE INFORMATION EXPRESSED IN
  MULTIPLE MEDIA, SUCH AS
• TEXT
• VOICE
• GRAPHICS / 3D
• IMAGES
• ANIMATIONS
• AUDIO
• VIDEO

MM Research Issues

• User Interface Design and AI
• Signal Processing and Coding
• Database issues
• Operating Systems
• Networking
• Protocols
• Synchronization
• Security and authentication
• Collaborative applications

Stringent QoS Constraints Network
End-to-End-Delay

• Tele-haptics
• 50-100 msec (dependent on refresh rates)
• Collaborative Virtual Environments
• 100-200 msec.
• Good Predictors are needed here (Dead Reckoning
  not good enough)

.We still have a lot of problems still to solve
here.

MM Sensor Networks Research

• Exciting field for MM research
• Wireless, small OS footprint, limited power,
  bring new constraints
• Ad Hoc Networking
• Source-to-sensor sink data download but with
  possible sensor-to-sensor messaging
• Redundant coverage and reliability essential
• New Protocols needed.

The future looks exciting but scary!
