SIMULTANEOUS IMAGE SWITCHING CONTROLLER AND GROUP SHARED IMAGE SWITCHING CONTROLLER

摘要

PURPOSE: To enable plural users existing in remote places to perform free and highly efficient image switching operations which are synchronous among plural image switching devices. ;CONSTITUTION: A user inputs a simultaneous image designating signal 181 to a simultaneous image designating signal analyzing part 105 via a communication network 101 and a communication interface 103. Thus the part 105 analyzes the contents of the signal 181 and then analyzes the cause and the contents of the signal 181 if an error is detected. Then an error signal 191 including the error analyzing result is sent to an error signal generating part 109 and an error signal 192 including the error analyzing result is generated therein. This signal 192 is sent back to the user via the interface 103 and the network 101. The contents of a simultaneous image switching destination storage part 107 are also referred to in the analysis of the signal 181 if necessary. At the time of reference, a simultaneous image switching destination output request 170 is sent to the part 107 from the part 105. Then the simultaneous image switching destination output 171 is sent back to the part 105.;COPYRIGHT: (C)1993,JPO&Japio
