Abstract: An image distribution system has a multiplexer (2) with inputs receiving images from images sources (41, 48). The multiplexer multiplexes images from said sources and provides on a connection (6) multiplexed images. Separate display devices (8, 10, 12) are connection in series to connection (6). Each display device has a demultiplexer (14, 16, 24) which receives multiplexed images and which outputs demultiplexed images. Using multiplexed sources and a single connection makes it possible to reduce the number of cables for distributing the images to the various display devices. The images displayed on one of the display devices may be changed at will without having to change the connection to the display device.

Abstract: A video wall (2) is formed of several adjacent displays (141-1415). The display surfaces of the adjacent displays form a continuous or quasi-continuous display surface for the video wall. The wall has an input adapted for receiving images from multiplexed sources. The images from the multiplexed sources are demultiplexed in a demultiplexer (22). The demultiplexer provides images from the demultiplexed sources to processors (241-2415) for display on the adjacent displays. Using multiplexed sources makes it possible to reduce the number of cables at the input to the wall or to increase the number of images that may simultaneously be displayed on the wall.

Abstract: A method and system of image processing are disclosed in which a source image is enlarged, the source image being represented by a source matrix of image elements having Y0 columns and X0 lines of image elements. The source image is enlarged and displayed on a visualization screen, comprising a matrix of N by M screens. Adjacent data elements within the source matrix are assigned to respective image windows within an M by N matrix having M N image windows, each image window being divided into X1 lines and Y1 columns of image elements. Each image element is sub-sampled to form an intermediate image matrix having X2 Y2 image elements. The resulting intermediate image matrix is then over-sampled to form an output image having X3 Y3 image elements. The resulting X3 Y3 image element output matrix is then registered to a matrix having Y4 columns and X4 lines of image elements, for subsequent display on the visualization screen.
