The purpose of this document is to provide a common reference and framework of standardsfor digital motion video and imagery, and to provide recommendations for utilization ofinternational standards for sharing or distributing motion video and imagery betweenspacecraft elements and ground systems.The scope of this document includes traditional real-time streaming video and television,including human and robotic spacecraft-to-spacecraft and spacecraft-to-ground systems, as wellas video recorded and distributed later, either as a real-time stream or as a file transfer. In thiscontext, real-time streaming includes all modes where video is sent from a spacecraft in acontinuous stream and is intended for immediate use when received, regardless of the latencyof the transmission path. Other specialized motion imagery applications, such as high-speedscientific motion imagery and multi-spectral motion imagery, are not addressed in thisdocument. However, if a specialized imagery camera system has a requirement to interface tospacecraft systems in a video mode, it would be required to match these interfaces.Ground-systems-to-ground-systems video distribution is obviously a key component of theentire video system. However, this is not the primary focus of this document. Currently,there are significant differences in the ways mission video products are exchanged betweenthe various space agencies on the ground. This is the result of differences in networktopologies between space agencies, and agreements for video sharing. Those differencespreclude there being a standard methodology for delivering video imagery between agencies.Prior to the commencement of video transmission between space agencies, system designreviews and performance testing should be done between the ground systems in use to assureoperability when video imagery comes from spacecraft.
