Embodiment Construction

[0030] According to the present invention, stream manager 102 ( figure 1 ) controls the flow of audiovisual data from the plurality of capture nodes 106A-C to the plurality of display nodes 108A-D through the switch 104. In this illustrative embodiment, switch 104 is a gigabit (Gb) Ethernet switch capable of about one gigabyte per second of point-to-point data throughput per port. Switch 104 overcomes the disadvantages of conventional bus interconnects in which only one device can write over the bus at any given time. A switch such as switch 104 can achieve maximum rated throughput for multiple channels simultaneously. As used herein, a stream of audiovisual data may include a stream of images and / or an audio stream, and "video" is used to refer to any sequence of images temporally related to each other.

[0031] Each capture node 106A-C receives an audio and / or video data stream and makes the data stream available to display nodes 108A-D through switch 104 . As used herein...

Abstract

Video data streams are routed between capture nodes and display nodes connected to one another through a high-bandwidth network switch and controlled by a stream manager connected to the switch. The stream manager negotiates a highest quality stream that can be processed by both the capture node and the one or more display nodes receiving the stream and that does not exceed available bandwidth through the switch. The stream manager includes a user interface by which a user can specify which of a number of video signals is to be displayed in what position within a display wall.

Description

[0001] This application is a continuation-in-part of US Patent Serial No. 11 / 111,182, filed April 15, 2005, by Eric Wogsberg, entitled "Audiovisual Signal Routing and Distribution System," which is hereby incorporated by reference in its entirety. technical field [0002] The present invention relates to audiovisual display systems, and more particularly to the efficient movement of multiple streams of audio and / or video data from multiple sources to multiple destinations. Background technique [0003] The increasing need to display more content in a single display has led to an increase in the production and sales of display walls. Display walls typically include multiple display monitors positioned adjacent to each other in a tiled fashion to present a single large image. Using relatively large flat panel display monitors and / or rear projection monitors and tiling them into 2x2, 3x3, 3x4 or other grid sizes, the composite displayed image can occupy an entire wall of the ro...
