1. A data communication system comprising:
- a first node that includes an image display monitor and an operating unit;
a second node that includes an operating unit but does not include an image display monitor, said first and second nodes communicating with each other by a DS-Link; and
arbitration means for providing an arbitration, for use of a communication path, between an instruction input at the operating unit of said first node and an instruction input at the operating unit of said second node.

Abstract
Disclosed are a data communication method whereby a first and a second node are directly connected so that they can exchange data directly, data communication apparatuses therefor, and a communication system that includes the apparatuses.
A VTR and a printer are connected by an IEEE 1394 cable. When the printer requests the transmission of image data, the VTR transmits pertinent image data to the printer. Since the entry of a predetermined instruction at the operating unit of the VTR is inhibited during the transmission of image data, the occurrence of an obstacle to the transmission of image data can be prevented.
