PROBLEM TO BE SOLVED: To improve the convenience of viewers by selecting channels for multiplexed broadcast signals received by a broadcast receiver with high response at a high speed. SOLUTION: This system issues broadcast signals subject to code division multiplex processing for a plurality of channels from ground broadcast stations BC1, BC2 to a broadcast receiver MS in a service area via a still satellite SAT. The ground broadcast stations BC1, BC2 transmit the broadcast signals where spread code phases between channels are matched and multiplexed, and the still satellite SAT detects a spread code phase difference between channels of a CDM broadcast signal received from the ground broadcast stations BC1, BC2, matches the spread code phases between the channels based on the result of detection, and transmits the resulting signals to the broadcast receiver MS. |
