Abstract :
We consider the problem of compressing a video sequence for transmission over a wireless channel. In our approach we jointly consider error resilience and concealment techniques, at the source coding level, and transmission power management at the physical layer. We formulate a minimum-maximum distortion problem, where our goal is to either (i) minimize the total transmission energy for a given maximum expected distortion, or (ii) minimize the maximum expected distortion at the receiver for a given maximum transmission energy. Experimental results show that simultaneously adjusting the source coding and transmission power is more energy efficient than considering these factors separately.
