Patent Images
1. A video distribution system, the system comprising:
- a capture node comprising;
capture logic for receiving a video signal in a native format; and
first format signal conversion logic, which is operatively coupled to the capture logic, for converting the video signal from the native format to an interchange format;
communication logic, which is operatively coupled to the first format signal conversion logic, for transporting the video signal in the interchange format; and
a display node comprising;
second format signal conversion logic, which is operatively coupled to the communications logic, for converting the video signal from the interchange format to a displayable format; and
display driving logic, operatively coupled to the second format signal conversion logic, for sending the video signal in the displayable format to a display device such that the display device displays the video signal.

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.
