Image display system
View Patent ↗An MPU storage device 114 stores a device address of an image display device 11 , and an MPU identification processing device 113 acquires and retains the device address stored in the MPU storage device 114 . The MPU identification processing device 113 acquires the device address from a device information storage device 122 or an MPU identification processing device 123 according to a DDC communication protocol, using an output side data sending and receiving device 115 . The device information storage device 122 stores EDID, and the MPU identification processing device 113 acquires EDID stored in the device information storage device 112 , compares it with the EDID acquired from the image display device 12 , extracts common data, and stores it in the device information storage device 112 as common EDID data of the image display device 11 and the image display device 12.
1. An image display system for realizing a multiple monitor system, incorporating an input interface and an output interface, said image display system comprising:
a data sending and receiving device which sends and receives device infonnation to and from image display devices connected in series to said input interface and said output interface, said image display devices being driven simultaneously,
an identification processing device which analyzes and processes data acquired by said data sending and receiving device, and
a storage device which stores control information and specification information of said image display devices, and device addresses allocated to said image display devices,
wherein said identification processing device reads specification information from image display devices connected to an output interface by using said data sending and receiving device, extracts data common to its own specification data to edit its own specification data, and stores the edited specification data in said storage device.
2. An image display system according to claim 1 , wherein said data sending and receiving device delivers data according to a DDC (Display Data Channel) communication procedure.
3. An image display system according to claim 1 , wherein said device addresses are selected from manufacturers' serial numbers of said image display devices, asset management numbers of said image display devices, and arbitrarily allocated numbers allocated to said image display devices, and said data sending and receiving devices deliver data using said device addresses.
4. An image display system according to claim 2 , wherein said device addresses are selected from manufacturers' serial numbers of said image display devices, asset management numbers of said image display devices, and arbitrarily allocated numbers allocated to said image display devices, and said data sending and receiving devices deliver data using said device addresses.
5. An image display system according to claim 1 , wherein said identification processing device identifies whether image display devices are connected to an output interface by using said data sending and receiving device, and identifies an operating state of the image display devices connected to the output interface.
6. An image display system according to claim 2 , wherein said identification processing device identifies whether image display devices are connected to an output interface by using said data sending and receiving device, and identifies an operating state of the image display devices connected to the output interface.
7. An image display system according to claim 3 , wherein said identification processing device identifies whether image display devices are connected to an output interface by using said data sending and receiving device, and identifies an operating state of the image display devices connected to the output interface.
8. An image display system according to claim 4 , wherein said identification processing device identifies whether image display devices are connected to an output interface by using said data sending and receiving device, and identifies an operating state of the image display devices connected to the output interface.
9. An image display system according to claim 1 , wherein said identification processing device remotely controls image display devices connected to an output interface using said data sending and receiving device.
10. An image display system according to claim 8 , wherein said identification processing device remotely controls image display devices connected to an output interface using said data sending and receiving device.
11. An image display system according to claim 1 , further comprising a response device which processes index control responses in a multiple monitor environment using indexes, even when it is not physically connected to a host computer.
12. An image display system according to claim 10 , further comprising a response device which processes index control responses in a multiple monitor environment using indexes, even when it is not physically connected to a host computer.
