A video wall (2) is formed of several adjacent displays (14 1-14 15). 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 far 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 (24 1-24 15) 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.

Why it's free to use
- Filed March 10, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended March 10, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 10, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
