DISPERSAL SIGNAL ADDING DEVICE

摘要

PURPOSE:To control the level of a dispersal signal to be eliminated automatically with a satellite from which the signal is received by ascertaining the level of the dispersal signal to be eliminated in a dispersal signal eliminating device at the receiver side. CONSTITUTION:A dispersal signal addition means 14 adds a dispersal signal by a level of the dispersal signal decided by a dispersal signal level decision means 13 to a MUSE signal added with information of the dispersal signal by a dispersal signal level information addition means 15 based on the timing when a dispersal signal addition timing generating means 12. Thus, the information of the dispersal signal level is added to the MUSE signal and the level of the dispersal signal to be eliminated is confirmed by a dispersal signal elimination device at a receiver side. Thus, the level of the dispersal signal to be eliminated by a satellite from which the signal is received automatically controlled.
