Abstract
A video projector, a cluster of video projectors and a method for wirelessly transmitting image data within the cluster of video projectors. The video projector includes a first antenna located at a first side of the projector and a second antenna located at a second side of the projector, opposite to the first side. Image data is divided into sub-parts, and distributed by assigning each image data sub-part to a video projector. A video projector receiving image data sub-parts extracts and stores the image data sub-part assigned to it, and retransmits image data sub-parts assigned to respectively a second and third video projectors.
