摘要： A system and method which delivers data at very high data transmission speeds to many locations simultaneously. A SCANS system is supplied with a satellite uplink communication module which transmits data to an earth orbiting satellite. The satellite then retransmits the data over a wide geographical area. Each receiving location is equipped with a small satellite dish to receive data from the satellite. Advantageously, the satellite dish is connected to a work station in the switching office which then processes the received data and delivers all information in a form that is ready for use by the modules' switching office. Errors during data transmission are noted for further processing. After the data is broadcast from the beginning to the end, the SCANS system pauses for a brief interval during which time each receiving station performs error detection, error correction, and other recovery procedures on the data it just received. The SCANS system, using satellite transmission, then broadcasts data once again from the beginning to the end. Receiving stations then selectively acquire data that was missing or in error after the first transmission.
