Resource aware real-time stream adaptation for MPEG-2 transport streams in constrained bandwidth networks

In this demo, we present three lean methods for real-time adaptation of live MPEG-2 video to limited and varying network bandwidth. Our methods use real-time resource management techniques to determine available resources and steer adaptation decisions. Then, the modified stream consists only of frames with a high likelyhood of being processed completely, the resulting stream will only use resources when they are effectively used. We present three related approaches, based on skipping entire frames, or frames and DCT coefficients for finer granularity and thus smaller underutilization.
