Abstract:
1. An apparatus connection interface comprising an image capturing apparatus; and a pair of connectors including a first connector and a second connector having respective signal transmission terminals for connecting a plurality of apparatus to be controlled and the image capturing apparatus in series to form an annular signal transmission line so as to circulate and transmit an operating condition confirming signal for confirming the condition of the apparatus to be controlled and the image capturing apparatus; and at the same time, circulate and transmit an operating condition notifying signal for notifying the condition of the individual apparatus to be controlled and the image capturing apparatus by way of the formed signal transmission line, wherein the plurality of apparatus include a plurality of videotape recorders and the image capturing apparatus controls the plurality of videotape recorders through a plurality of the apparatus connection interfaces, wherein each of the first and second connectors has a pair of one direction signal transmission terminals for sequentially transmitting the operating condition confirming signal and the operating condition notifying signal to the plurality of apparatus to be controlled connected in series in one direction directed from a connection starting extremity to a connection ending extremity and a pair of other direction signal transmission terminal for sequentially transmitting the operating condition confirming signal and the operating notifying signal to the plurality of apparatus to be controlled on the other direction directed from the connection ending extremity to the connection starting extremity in order to form a confirmation signal transmission line for circulating and transmitting the operating condition confirming signal and a notification signal transmission line for circulating and transmitting the operating condition notifying signal as the signal transmission line, and wherein each of the first and second connectors has a pair of one direction signal transmission terminals and a pair of other direction signal transmission terminals as the signal, transmission terminals in order to separately form the confirmation signal transmission line and the notification signal transmission line that transmits the operating condition confirming signal and the operating condition notifying signal in opposite directions.
