Capture node for use in an audiovisual signal routing and distribution system
First Claim
Patent Images
1. A video capture node for use in a video signal distribution system, the node comprising:
- capture logic for receiving a video signal in a native format;
signal format conversion logic, which is operatively coupled to the capture logic, for converting the video signal from the native format to an interchange format; and
signal transmission logic, which is operatively coupled to the signal format conversion logic, for sending the video signal in the interchange format to a remotely located display node such that the display node converts the video signal from the interchange format to a displayable format and 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.

43. A method for displaying a video signal, the method comprising:
-
receiving a video signal in a native format;
converting the video signal from the native format to an interchange format; and
sending the video signal in the interchange format to a remotely located display node such that the display node converts the video signal from the interchange format to a displayable format and causes display of the video signal. - View Dependent Claims (44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84)
