PROBLEM TO BE SOLVED: To provide the information transmission method that properly realizes countermeasures against the occurrence of a reception error in a terminal equipment regardless of an advantage of simultaneous transmission of information in a broadcast form from a host device to a plurality of terminal equipments. SOLUTION: In the case of transmission of data from a host device 2 to a terminal equipment 1, since the data are transmitted while being multiplexed on a satellite broadcast wave through a satellite channel, an advantage of simultaneous transmission of large capacity data in a broadcast form is obtained at first. Then on the occurrence of a reception error in a terminal equipment 1, the error is countermeasured as follows; each terminal equipment 1 detects an error for each information in the unit of frames and up-loads the reception result denoting the presence of the error to the host device 2 for each information, and the host device 2 sends the information with many error detection numbers to the terminal equipment 1 again based on the reception result up- loaded from each terminal equipment 1. |
