Abstract : The study was made to provide data about the characteristics of meteorological weather pictures that would allow efficient application of data compaction processes to the transmission and reproduction of these pictures. The equipment utilized for this study were the government-furnished Automatic Picture Transmission (APT) Ground Station and the Radiation Incorporated Data Management Analyzer (DMA). The APT system provided a means of scanning pictures, generating video signals, transmitting these signals, and then reconstructing a final output picture from this data. The Data Management Analyzer was used to process the data between the transmitter and receiver to simulate an actual data compression transmission system. The flexibility of the DMA enabled the selection of a number of different processing modes and provided all required data to quickly evaluate the effects of these different processes. The goal of the study was to obtain a minimum reduction ratio of 5 to 1 with acceptable picture quality. This goal was accomplished. (Author)
