Optimally smooth error resilient streaming of 3-D wireframe animations

Some concepts from a number of fields were brought together to address the problem of how to achieve optimal resilience to errors in terms of the perceptual effect at the receiver. To achieve this, the animation stream was partitioned into a number of layers and applyied Reed-Solomon (RS) forward error correction (FEC) codes to each layer independently and in such a way as to maintain the same overall bitrate whilst minimizng the perceptual effects of error, as measured by a distortion metric derived from related work in the area of static 3-D mesh compression. Experimental results show that the efficacy of the proposed scheme under varying network bandwidth and loss conditions for different layer partitionings.
