Abstract
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.
