Network displays and method of their operation
First Claim
1. A display system for displaying streaming image data from a source of video signals on a plurality of display units linked by a network, comprising:
- a network processing block that uses a progression mechanism to separate a video signal containing a video frame into multiple streams, said multiple streams each including data that, when combined by a decoder, form an image having a resolution that depends on a number of streams that are being combined and that is less than full-resolution when the number of streams that are being combined is less that the number of streams into which the video frame is divided; and
a plurality of display units linked by the network, each including at least one said decoder,wherein the networked display units are adapted to selectively subscribe to a number of streams less than said number of streams forming said full resolution image.

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.

10. A method for displaying streaming image data on a plurality of display units linked by a network having one or more networked display units, comprising the steps of:
-
using a progression mechanism to separate a video signal containing a video frame into multiple streams, said multiple streams each including data that, when combined by a decoder, form an image having a resolution that depends on a number of streams that are being combined and that is less than full-resolution when the number of streams that are being combined is less that the number of streams into which the video frame is divided; and a plurality of display units linked by the network selectively subscribing to a number of streams less than said number of streams forming said full resolution image. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
