Title:
COOPERATIVE DISPLAY SYSTEM
Document Type and Number:
Japanese Patent JP3658830
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make the synchronization of display between terminals and the high responsiveness of the display to input compatible when a data transmission interval is large for an input data generation interval.
SOLUTION: In an editing means 7, a transmission data editing method is selected, based on input data and data inside a buffer 8 and editing is performed. For instance, the plural data inside the butter 8 are collected for the transmission of one time in the case of handwriting plotting and the old data among a plurality of data inside the buffer 8 are eliminated and only the latest data are left in the case of pointer display. The data after performing such editing are sent out to the other terminal by a send-out means 9, transmission completion signals from a transmission destination terminal are confirmed in a transmission confirmation means 11 and then, the display is performed at the display means 6 of the respective terminals. Thus, by the reduction of data transmission time by the reduction of the number of times of the transmission and the display after confirming data transmission, the responsiveness of the display to the input of an operator is improved and the synchronization of the display between the terminals is made possible.
