Media Adaptation
What is Media Adaptation ?
Supporting audio & video streams with no resource reservation
in real-time on the LANs (mostly ethernet and token ring technology)
Important issues
- Understanding network conditions: access constraints vs capacity constraints
- Monitoring the network: by monitoring the display queue
- Adapting to the network: by either
- changing the amount of data sent (different compressions scheme and/or less quality data) - Sometimes there is a trade off between latency and quality.
- or changing the way the data is sent (package the data differently)
