Bidirectional communication system in a remote control system for an audio/video system
First Claim
1. A bidirectional communication system in a remote control system for an audio/video system including a remote controller and a plurality of controlled units controlled by the remote controller, comprising:
- communication lines connecting the controlled units with each other for bidirectional communication;
each of the controlled units having a signal receiving section for receiving a command from the remote controller, a signal transmitting section for transmitting a wireless response to the remote controller, computer means for controlling the signal receiving operation and the signal transmitting operation and the bidirectional communication between the controlled units through the communication lines, and being given a precedence for responding to the command;
the computer means having,transmitting means responsive to the command for applying a response preparing data, including a unit identification code, to other controlled units through the communication line,receiving means for receiving the response preparing data from other controlled units through the communication line,determining means for determining whether the precedence of the unit itself is higher than those of the other controlled units and for producing a precedent signal when the precedence of the unit is higher,responding means responsive to the precedent signal for generating the wireless responses, andabandon means for applying a response abandon data to the other controlled units at a time when it is determined that the precedence of the unit is lower than those of the other controlled units after applying the response preparing data to the other controlled units.

Abstract
A plurality of controlled units are connected with each other by communication lines for bidirectional communication. Each of the controlled units has a computer for controlling the bidirectional communication between the controlled units through the communication lines. The computer has a transmitting device responsive to a command from a remote controller to apply a response preparing data to the other controlled units, a receiving device for receiving response preparing data from the other controlled units. A precedence is give to each controlled unit. When the precedence of the unit itself is higher than that of the other controlled unit, a wireless response is applied to the remote controller.
