Paper Abstract

The central payload video system, CPVS, is a highly flexible central video facility designed to perform processing on payload video as well as system video. Although developed under the Columbus program the CPVS can be easily integrated into any space station program such as Freedom and MIR. The CPVS is compatible with component video (Y,C) as well as with composite video (standard NTSC and PAL). The CPVS also supports non standard video high resolution (geometrical) and high frame rate (excellent time resolution) video. The CPVS is converting all received video into digital video. The standard formats are compatible with the world wide recognized standard, D1 (CCIR 601 and CCIR 656 compatible), and the non standard formats are compatible with an extrapolation of the D1 standard. The CPVS is able to process up to eight (8) simultaneous video channels. The CPVS is able to route any input to any or all processing elements using an internal switching and routing unit. The number and type of processing elements can be chosen according to every mission needs and new processing standards can be supported with little or no modification. The selected D1 standard ensures excellent video quality, and the fully redundant design of the CPVS ensures maximum availability of the system for the users. The selection of standard video formats and standard processing algorithms (compression) allows the use on ground of low-cost, off-the-shelf video equipment. The CPVS operation is based on tables which are generated on ground and loaded on board to be executed at a given on board time without the need of real time interaction.
