Problems of Wireless Multi-media

multi-media applications require real-time continuous transmission of huge quantities of data

smaller and dynamic bandwidth offers only limited and time-varying data rates

bursty errors with higher error rates are difficult to correct

errors translated to packet loss, which are not acceptable

packets out of sequence also creating problems

time-varying transmission quality even varies across different wireless technologies

Transport Level Issues in Wireless Multi-media
proposed approach for wireless multi media
Improved Link Level Technologies

better link quality

Enhanced Transport Level Protocols

to accommodate multi-media traffic and link unreliability

Developing “Convergence Functionalities” in the Application Level

wireless link level problems and transport level variations become transparent to “core technologies”

“core technologies” shielded from and equally applicable to all different link/transport environments

examples: scalability, error concealment,etc.

Robust “Core Technologies” including Intelligent User Interfaces

Combatting with residual errors

Examples: signal verification,error resilience, etc.
