A video projector, a duster of video projectors and a method for wirelessly transmitting image data within the cluster of video projectors

摘要

The video projector comprises a first antenna (211) located at a first side (321) of the projector and a second antenna (212) located at a second side (322) of the projector, opposite to the first side. The first antenna is configured to form a first radiation pattern (301) that extends outwardly from the first side, the second antenna is configured to form a second radiation pattern (302) that extends outwardly from the second side, and wherein the first and second radiation pattern do not interfere. A wireless cluster of such video projectors are arranged so that the projectors communicate using the antennae. A wireless transmission method for the cluster divides image data into several sub-parts each of which are assigned to a video projector so that a composite image is displayed by the cluster which may form a multi-projection system.
