The Digital Video System (DVS) is a state-of-art electronic equipment that transfers the latest technologies of digital image compression onto a space platform. The DVS represents an alternative to the analogue video modules currently employed on board sounding rockets offering several benefits with respect to them. The DVS is composed of a flight unit named Wavelet Compression Unit (WCU) and a ground unit named Wavelet Decompression Unit (WDU). The WCU is a small unit that performs real-time video compression by implementing at hardware level an adaptive wavelet compression algorithm. The WDU is the ground counterpart of the WCU that receives the compressed video data stream from the Ground Telemetry Station, performs the real-time video decompression and displays images on standard analogue monitors or PC monitors. The DVS is the latest result in the field of digital image processing after years of research and development of precursor systems already employed on board sounding rockets and capsules. The system will be demonstrated on board the MASER9 during the 2001 fall campaign.
