SATELLITE COMMUNICATION CONTROLLER

摘要

PURPOSE:To attain data communication without occupying a specific band in the satellite communication by adding an error correction code to transfer data from a host machine and outputting the result as data of an independent data part in a frame of a satellite broadcast PCM sound signal from a satellite broadcast scrambler. CONSTITUTION:A satellite communication controller 11 fetches transfer data from a host machine 15 and the controller adds an error correction code to the data to form error coding data. The data are outputted from a transmission station 1 to a broadcast or satellite communication satellite 5 as data of an independent data part in a frame of a satellite broadcast PCM sound signal from a satellite broadcast scrambler 7. A tuner 17 receives a signal from the satellite 5, a descrambler 21 implements error correction and a satellite communication controller 25 sends data to work stations 29, 31. Thus, a data error of satellite communication is reduced without occupying a specific band and data communication with high reliability is implemented.
