Signal transmission system, signal receiving device, signal sending device, signal receiving device control program, and signal transmission method

摘要

A signal transmission system includes: a signal sending device including a signal sender converting a sending signal to a transmission signal using a signal sending parameter and sends the transmission signal to a signal path, and a sending controller receiving a sending control signal and changes the signal sending parameter according to the sending control signal; and a signal receiving device including a signal receiver converting the transmission signal received via the signal path, to a reception signal using a signal reception parameter, a signal reception monitor monitoring a signal reception status of the transmission signal and outputs monitor information acquired by the monitoring, and a reception controller checking transmission quality of the signal path using the monitor information, creates the sending control signal for changing the signal sending parameter according to a checking result to send, and changes the signal reception parameter.

1. A signal transmission system comprising:
a signal sending device including
a first signal sender which converts a sending signal to a first transmission signal by using a first signal sending parameter and sends the first transmission signal to a first signal path,a second signal sender which converts the sending signal to a second transmission signal by using a second signal sending parameter and sends the second transmission signal to a second signal path, anda sending controller which receives a first sending control signal and changes the first signal sending parameter or the second signal sending parameter according to the first sending control signal; and a signal receiving device including
a first signal receiver which converts the first transmission signal received via the first signal path, to a first reception signal by using a first signal reception parameter,a first signal reception monitor which monitors a signal reception status of the first transmission signal and outputs first monitor information acquired by the monitoring,a second signal receiver which converts the second transmission signal received via the second signal path, to a second reception signal by using a second signal reception parameter,a second signal reception monitor which monitors a signal reception status of the second transmission signal and outputs second monitor information acquired by the monitoring,a reception controller which checks transmission quality of the first signal path and the second signal path by using the first monitor information and the second monitor information, creates and outputs a switching signal for selecting the first reception signal or the second reception signal, creates and sends the first sending control signal for changing the first signal sending parameter or the second signal sending parameter according to a result of the check, and changes the first signal reception parameter or the second signal reception parameter corresponding to the signal path which is not selected by the switching signal.
