Network monitoring system, reproduction terminal, and monitoring terminal
First Claim
1. A network monitoring system that shares a network line with at least another communication system, the network monitoring system comprising:
- monitoring equipment including;
an encoder for compressing image data;
a data transmission unit for transmitting monitoring information including compressed image data through the network line; and
an information-amount adjustment unit for adjusting an amount of information per unit time of the monitoring information to be transmitted from the data transmission unit;
a reproduction terminal including;
a data receiving unit adapted to receive the monitoring information transmitted from the monitoring equipment through the network line; and
a decoder for decompressing compressed image data included in the monitoring information;
a calculation unit for calculating the transmittable amount of information which calculates the transmittable amount of information per unit time of the network line; and
a calculation unit for calculating the transmitted amount of information which calculates the transmitted amount of information per unit time of the monitoring information to be transmitted on the basis of a predetermined occupation ratio in order to determine a ratio of the monitoring information to the calculated transmittable amount of information;
wherein said information-amount adjustment unit is controlled on the basis of the transmitted amount of information per unit time which has been calculated by the calculation unit for calculating the transmitted amount of information.
