Abstract
Plural information display stations, such as audio video devices, are commonly connected to an information transmission path which transmits data frames among the display stations to provide data communication therebetween. Display information from the plural display stations is readily displayed on a common display monitor of one of the display stations. The display station containing the monitor transmits an inquiry on the information path for the purpose of determining which of the other display stations contains display information. The addresses of the other stations which transmit an affirmative reply in response to the inquiry are stored. Also, the display station containing the display monitor transmits another inquiry to determine the type of contents of the display information of the other display stations. The type of contents transmitted in response to this inquiry are also stored. Additionally, the control right of the display on the display monitor may be transferred among the plural display stations.
