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.
Claims1
A method for sending a video stream from a source node to a display node through a network, the method comprising:
- in a stream manager that is separate from the source node and the display node, sending destination control information through the network to the display node to cause the display node to receive and accept the video stream from the source node through the network;
- and
- in the stream manager, sending source control information through the network to the source node to cause the source node to send the video stream to the display node through the network;
- wherein, in response to the destination control information, the display node receives and accepts the video stream from the source node through the network;
- and
- further wherein, in response to the source control information, the source node sends the video stream to the display node through the network.
