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.
Claims106
A video distribution system, the video distribution system comprising:
- a capture node comprising:
- capture logic for receiving a non-packetized video signal in a scanline-based native format;
- first signal format conversion logic, which is operatively coupled to the capture logic, for converting the video signal from the native format to a scanline-based interchange format by packetizing the video signal;
- first communication logic, which is operatively coupled to the first signal format conversion logic, for communicating with a display node and transporting the video signal in the interchange format;
- and
- negotiation logic, operatively coupled to the first signal format conversion logic;
- the display node comprising:
- second signal format conversion logic, which is operatively coupled to the first communication logic, for converting the video signal from the interchange format to a scanline-based displayable format;
- display driving logic, operatively coupled to the second signal format conversion logic, for sending the video signal in the displayable format to a display device such that the display device displays the video signal in the displayable format;
- and
- negotiation logic, operatively coupled to the second signal format conversion logic;
- wherein the negotiated logic of the capture node and the negotiation logic of the display node cooperatively select the interchange format.

- negotiation logic, operatively coupled to the third signal format conversion logic;
- and
- wherein the negotiated logic of the capture node and the negotiation logic of the display node cooperatively select the interchange format.
