Network displays and method of their operation
First Claim
1. A display system (10) for displaying streaming image data, comprising display generator units (14) each comprising a processing means and a memory, a shared resource network (13) linking the display generator units (14), the shared resource network (13) being adapted to receive a plurality of input source signals encoding images to be displayed, a plurality of display units (15), the display units (15) being for display of at least some of the images encoded in the input source signals, wherein each display generator unit (14) is adapted for storing a configuration document-(61), the configuration document (61) including a definition of a task of all display generator units (14).

Abstract
A digital networked studio and the needed software services to allow the use of the system for monitoring the creation and distribution processes of real-time created content is described. Distribution problems are solved using an off-the-shelf network, e.g. using an IP based or similar data protocol, such as an IP network based distributed system architecture to bring the display controller functionality closer to the source and to replace proprietary busses used for transporting video, audio, RGB, graphical information and/or metadata with building blocks based on standard IP and compression technologies. A characteristic of such a network is to use unicast, multicast and/or broadcast technologies (based on network addresses) and to route data from one address to another. The network provides redundancy in case any of the digital generation units.
