SWITCHING SYSTEM, TRANSMISSION DEVICE, TRANSMISSION METHOD AND SWITCHING METHOD FOR SATELLITE

摘要

PROBLEM TO BE SOLVED: To provide a satellite communication system for relaxing increase in the number of apparatuses, the volume and the power consumption associated with the mount of reproduction processes on a satellite. SOLUTION: This invention provides the data switching system for a satellite in a satellite data transmission system which relays from a terrestrial sending area to a terrestrial receiving area via the satellite data including payload data and associated control data which constitute respective switching requests and provide data on the switching of the payload data. This system analyzes data on the basis of a signal conveying the control data and switches the payload data in response to a result of the analysis of the associated control data to at least one of a plurality of sending ports for sending the data to the receiving area. Only the control data are analyzed. The payload data are not analyzed. COPYRIGHT: (C)2004,JPO
