  • Patent number: 9860345
    Abstract: A method and system for displaying graphics on a display of a second module remotely connected with a first module via a data communications medium. A first controller interfaces between a first graphics processor and the first module. A second controller interfaces between a second graphics processor and the first module via the data communications medium and the first controller. The first controller duplicates data returned to the first graphics processor by the first module in response to data requests, and transmits the duplicated data to the second controller. The second controller intercepts data requests by the second graphics processor to the first module, correlates the intercepted requests with the duplicated data received from the first controller and transmits the duplicated data to the second graphics processor based on this correlation. The second graphics processor uses the received duplicated data to generate graphics for display at the second module.

  • Patent number: 9665740
    Abstract: A system and method for cryptographically securing a graphics system connectable via an external bus to a computing system, the graphics system including a graphics processor, a video memory and a memory controller for controlling the flow of data to and from the video memory. The graphics system further includes a copy engine for copying data between a system memory of the computing system and the video memory, where this copy engine acts independently of the graphics processor of the graphics system. The present invention enables the copy engine of the graphics system to decrypt encrypted data in the course of copying data from the system memory to the video memory and to encrypt unencrypted data in the course of copying data from the video memory to the system memory. Thus, cryptographic protection of secure content may be assured by the graphics system without the excessive usage of its primary resources for this non-graphical purpose.

  • Patent number: 8410994
    Abstract: A method and system for displaying graphics on a display of a second module remotely connected with a first module via a data communications medium. A first controller for the first module and a second controller for the second module are connected to first and second graphics processors, respectively, both graphics processors being operative to request data from the first module when ready to process data. The first controller interfaces between the first graphics processor and the first module. The second controller interfaces between the second graphics processor and the first module via the data communications medium and the first controller. The first controller duplicates data returned to the first graphics processor by the first module in response to data requests, and transmits the duplicated data to the second controller via the data communications medium.

  • Publication number: 20090139122
    Abstract: A device (1) for displaying an aggregate image (2) the form of a matrix. Each cell (4) of the matrix (3) enables display of an elementary image (6). The elementary images are carried out on a ribbon (7). In order to vary the aggregate image, the elementary image is varied, the former being selected on the ribbon by causing the ribbon to run off inside the cell. The device enables the creation of very large display panels, particularly those used at airports.
