Control system for picture display apparatus having improved displaying data transmission system
First Claim
1. A control system for picture-display apparatus comprises a first picture-display apparatus comprising:
- a first display device having a screen for displaying pictures on said screen so that said screen is refreshed at first frequent predetermined screen refreshing intervals;
a first display-device control means for outputting the displaying data to said first display device at said first frequent predetermined screen refreshing intervals;
storing means for storing the displaying data;
a displaying-data control means for reading the displaying data stored in said storing means at first frequent predetermined screen renewal intervals, said displaying-data control means then outputting the read displaying data to said first display-device control means, wherein each of said first frequent predetermined screen refreshing intervals is shorter than each of said first frequent predetermined screen renewal intervals;
wherein display-data control means further converts displaying data read from the storing means into a serial form of the displaying data and outputs it to at least one second picture-display apparatus at second frequent predetermined screen renewal intervals, wherein each of said first frequent predetermined screen refreshing intervals is shorter than each of said second frequent predetermined screen renewal intervals;
wherein a display-data control means of said second picture-display apparatus inputs said serial form of the displaying data and converts it into parallel form of the displaying data which is then supplied to a second display device of said second picture-display apparatus at second frequency predetermined screen refreshing intervals which correspond to said second display device;
wherein said first picture-display apparatus further comprises communication means for communicating with said second picture-display apparatus; and
wherein said first picture-display apparatus uses an electric cable for transmitting the serial form of the displaying data to said at least one second picture-display apparatus so as to distribute the pictures currently displayed on said screen of said first display device to said at least one second picture-display apparatus.
