CONTROL-SIGNAL PROCESSING SYSTEM, CONTROL-SIGNAL TRANSMISSION DEVICE, AND COMMAND PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a control-signal processing system that realizes control accuracy in one field, and to provide a control-signal transmission device and a command processing method.;SOLUTION: A node Q on a control device side transmits a command to which count 2 is added as a precedent field information to a node q in a controlled device, in a vertical synchronization field Tb2 three fields before a vertical synchronization field Ta in which the command is to be executed, and repeats command transmission while the count is decremented by one for each new vertical synchronization field until a last vertical synchronization field T0. The node on the controlled device side receives and stores the command and thereafter reads out precedent counts for each vertical synchronization or decrements the count by one for each vertical synchronization, and if the count reaches zero, executes the command in the vertical synchronization field immediately thereafter.;COPYRIGHT: (C)2013,JPO&INPIT
