PROBLEM TO BE SOLVED: To control the data compression state of a slave set designated by a master set, and the adjustment state such as camera turning and zooming. SOLUTION: A master station 9 selects a desired slave set based on an ID code allocated to plural slave sets 4 through radio communication by using the direct spread system spread spectrum modulation. Then the master station allows the selected slave set to send video data from a monitor camera 1 connecting to the slave set through compression and the master station receives the data and demodulates the data so as to monitor the data with a monitor connecting to the master set in the radio monitor system. Each slave set is provided with a data compression control section 6, a camera control signal demodulation section 42, and a camera control signal output section 5, and the master set is provided with a data compression control signal input and camera control signal input section 10, a compression control signal generating section 12 and a camera control signal generating section 11 respectively. Then the master station controls data compression state of each slave set and controls the monitor camera. |
