Abstract

Including a buffer storage into a telemetry data compression system has proven to be both a requirement and a nemesis. Some video compression simulation results which help define buffer requirements for transmitted bit-rate reductions of 2:1 and 3:1 are summarized. The zero-order predictor algorithm with a buffer-controlled variable aperture was found to provide both efficient buffer utilization and acceptable means of controlling buffer "underflow" and "overflow." The investigation was limited to worst-case nonstationary video data.
