<p>PURPOSE:To easily monitor the state of an information source by registering an access claim to the entire connected information sources in a table, and independently monitoring the state of the information source by an information source state monitoring device provided at each system block. CONSTITUTION:A single information source state monitoring device 20 common to system blocks 11(1) and 11(2) is set. A monitoring device number divided by each block is registered in the monitoring device 20. And also, the monitoring device 20 is connected with video switches part 12 and 15. Each connection management table 13 and 16 registers the access claim to entire corresponding information sources 10(1)-10(n), and 18(1)-18(n). At the time of monitoring the state of the information source, the blocks 11(1) and 11(2), and the information sources 10 and 18 are designated by the system block designating part of the monitoring device. Then, the information sources 10 and 18 designated by switching the switches 12 and 15 are connected with the monitoring device 20. The monitoring device 20 displays the information from the information sources 10 and 18, and monitors the operation.</p> |
