Abstract

The embodiments described in this disclosure address the above issues and others. Accordingly, a self-configuring IP video router provides a plug-and-play transport interface between two LANs, one of which is the host to multiple IP video cameras or servers.

In accordance with an aspect of the disclosure, plug-and-play functionality provides that the device can be connected to both networks via standard hardware interfaces, discover the video sources on the “inside” network, and configure itself to do the appropriate IP address mapping and IP port transport across the interface between the networks.

Claims

1. An automatic video router for providing a transport interface between first and second networks, wherein:

the first network is operable as a host to multiple Internet Protocol (IP)-based video systems;

the second network is separate from the first network; and

the router is connected to the first and second networks, the router comprising plug-and-play functionality operable for;

providing a connection to both of the first and second networks via standard hardware interfaces; and

discovering the video sources on the first network,

wherein the discovering of the video sources includes determining whether a device on the first network is a video source based on a Media Access Controller (MAC) address of the device received by the router in response to a broadcast message issued from the router.

2. The automatic video router according to claim 1, wherein the automatic video router is further operable for automatically providing respective IP addresses to video sources during the discovering of video sources.

3. The automatic video router according to claim 2, wherein, for at least one video source automatically provided with an IP address, the automatic video router is further operable for automatically assigning a port number to the IP address, the port number being addressable from the second network.

4. The automatic video router according to claim 3, wherein the port number is assigned based on a predetermined algorithm for mapping between IP addresses and the port numbers.

5. The automatic video router according to claim 4, wherein the predetermined algorithm for mapping includes mapping the port number to the IP addresses so that the port number and IP address each include an identical subset of digits.

6. The automatic video router according to claim 2, wherein, for at least one video source automatically provided with an IP address, the automatic video router is further operable for assigning an alphanumeric name to the video source.

7. The automatic video router according to claim 6, wherein the assigning of the alphanumeric name to the video source includes retrieving, by the automatic video router, name information from the video source and mapping the alphanumeric name to the IP address of the video source.

8. The automatic video router according to claim 1, wherein the automatic video router is further operable for receiving a video stream from the device on the first network and outputting a plurality of replicas of the video stream to the second network.

9. The automatic video router according to claim 1, wherein the automatic video router is further operable for generating a web page that includes a list of video sources on the first network.

10. The automatic video router according to claim 9, wherein the web page further includes a table of snapshots from each of the video sources on the first network.

11. The automatic video router according to claim 9, wherein the web page further includes links to the video sources on the first network.
