Abstract

This paper proposes a power management mechanism, via cross-layer design over application/presentation, data-link, and physical layers, for power-limited receivers in a multimedia streaming system such as the digital audio/video broadcasting system. In the transmitter, fine grain scalable source coding is utilized in the application/presentation layer to produce a bitstream of video frames that are further processed to form several partition streams in the data-link layer. Then, the partition streams are transmitted in bursts through time-slicing based modulation over the physical layer. Accordingly, depending on acceptance of various multimedia quality which is in proportion to the amount of data to be processed, power consumption can be autonomously managed by the receivers with great flexibility and wide dynamic range.
