SATELLITE BROADCAST RECEIVER

摘要

PURPOSE:To attain transmission/receiving with high accuracy by transmitting a correct data again even if erroneous data is transmitted. CONSTITUTION:If a part of data is in error due to the condition of external environment it is detected by an error detecting circuit 34 in a descrambling device 32 and it is informed to a broadcast station 1 through a line 6 from the circuit 34. The broadcast station 1 retransmits the correct data to a subscriber 3 designated again by SHF signal 4, 5. As a result, the correct data is transmitted to the subscriber 3 in a short time.
