Abstract

In this paper we propose an adaptive region-based, multi- scale, motion compensated video compression algorithm designed for transmission over hostile communication channels. Our codec extracts spatial information form video frames to create video regions that are then decomposed into sub-bands of different perceptual importance before being compressed and transmitted independently. This allows the system to apply unequal error protection, prioritized transmission, and 'lego-reconstruction' to guarantee a minimum spatial and temporal resolution at the receiver. Furthermore, the region segmented frames bound both spatial and temporal error propagation within frames and when combined with our novel connection-level inter-region statistical multiplexing scheme ensure optimal utilization of the reserved transmission bandwidth. Simulation results demonstrate that in the presence of severe time-varying error conditions and severe bandwidth constraints, our video codec exhibits better error concealment, better temporal resolution, and better bandwidth utilization properties than the popular International Telecommunication Union's and International Standard Organization's video coding standards.
