An audiovisual signal is converted from a native format to a digital, packetized interchange format and transported between a capture node and a display node through a switch. The display node converts the audiovisual signal from the interchange format to a displayable format and causes display of the audiovisual signal. The use of a switch for video routing and distribution allows one-to-one, one-to-many, many-to-one, and many-to-many distribution. The use of a device-independent interchange format allows concurrent distribution of multiple heterogeneous audiovisual signals.

Interconnection mechanism for multiple data streams

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.

A device for converting display parameters adapted for use with a personal computer having a display defined by a first set of parameters to a display having a second set of parameters. The converter includes a latch for storing data received from the microcomputer data bus that is indicative of the parameter to be controlled and a read only memory coupled to the latch and also coupled to the data bus. The read only memory will select a new value corresponding to the parameter to be converted from data received from the latch and the parameter data received from the data bus.
