Stream Adaptation
•Link Capacity Adaptation
–Splices wide-band links with low capacity links.
–Application aware rate adaptation.
•Greater down-scalability range (4/5th vs. 1/100th)
–Perceptual encoding
•Interactive data compression with perceptual control over where and how quality is compromised.
•
•Node Capacity Adaptation
–Allows network junction nodes with unequal CPUs to
perform rate adaptation.
–Auto-configuration by motion vector bypass
•Reuses motion vector and saves computation for quality
–Cycle sweeping (network spread)
•If one node is not enough it spreads the computation
upstream and sweeps additional cycles
from active nodes.
