Abstract

A wide area mirroring router enables mobile device screen minoring across a wide area network. The wide area minoring router (WAMR) is in wireless communication with a mobile device to receive Internet Protocol (IP) packets, including multicast packets, containing data related to minoring content displayed on the mobile device to a remote display device. The WAMR encapsulates the IP packets into envelopes for transmission via a tunnel to the remote display device over the wide area network.

Claims

1. An apparatus, comprising:

a processor for receiving Internet Protocol (IP) packets containing data related to minoring content displayed on a mobile device to a remote display device, the IP packets including multicast packets, the processor further for encapsulating the IP packets into envelopes for transmission via a tunnel to the remote display device; and

an interface for communicating the envelopes to the remote display device via the tunnel over a wide area network.

2. The apparatus of claim 1, wherein the multicast packets are multicast domain name system (DNS) packets.

3. The apparatus of claim 1, wherein the mobile device includes the apparatus and the interface is a wireless interface.

4. The apparatus of claim 1, wherein the apparatus is a wireless router in wireless communication with the mobile device and the interface is a network interface.

5. The apparatus of claim 4, wherein the network interface is a wireless network interface.

6. The apparatus of claim 1, wherein the apparatus is a digital media receiver, TV, projector or graphical monitoring device.

7. The apparatus of claim 1, wherein the processor further filters the IP packets to prevent packets unrelated to minoring of the content from being encapsulated into the envelopes.

8. The apparatus of claim 7, further comprising:

a memory maintaining IP tables, the processor using the IP tables to filter the IP packets.

9. The apparatus of claim 1, wherein the processor further encrypts the data prior to encapsulating the IP packets into the envelopes.

10. The apparatus of claim 1, wherein the processor further provides a virtual Ethernet bridge for bridging a wireless domain coupling the mobile device to the apparatus and a wired domain coupling the apparatus to the wide area network.

11. The apparatus of claim 10, wherein the wireless domain is a wireless local area network (LAN) and the wired domain is a wired LAN.

12. The apparatus of claim 1, wherein the processor further receives additional content mirrored from a remote mobile device via the interface through an additional tunnel and transmits the additional content to a local display device for display of the additional content thereon.

13. The apparatus of claim 1, wherein the mobile device is a remote mobile device and the processor further receives the IP packets via the interface through an additional tunnel and bridges the tunnel and the additional tunnel together.

14. The apparatus of claim 1, wherein the mobile device is a tablet or smartphone.

15. A wide area mirroring router, comprising:

a transceiver in wireless communication with a mobile device for receiving Internet Protocol (IP) packets from the mobile device, the IP packets containing data related to mirroring content displayed on the mobile device to a remote display device, the IP packets further including multicast packets;

a processor for encapsulating the IP packets into envelopes for transmission via a tunnel to the remote display device; and

a network interface for communicating the envelopes to a digital media receiver coupled to the remote display device via the tunnel over a wide area network

16. The router of claim 15, wherein the tunnel is a User Datagram Protocol (UDP) or Transmission Control Protocol (TCP) tunnel.

17. The router of claim 15, wherein the transceiver communicates with the mobile device via a WiFi communication link.

18. The router of claim 15, wherein the multicast packets are multicast Domain Name System (DNS) packets.

19. The router of claim 15, further comprising:

a memory maintaining IP tables;

a virtual Ethernet bridging module executable by the processor for bridging a wireless domain coupling the mobile device to the router and a wired domain coupling the router to the wide area network;

a filtering module executable by the processor for filtering the IP packets, using the IP tables, to prevent packets unrelated to minoring of the content from being encapsulated into the envelopes; and

a virtual private network (VPN) adapter module for creating the tunnel and encapsulating the IP packets into the envelopes for transmission via the tunnel.

20. The router of claim 15, wherein the wide area network includes at least one of a corporate or campus Local Area Network (LAN), corporate or public Wide Area Network (WAN), Mobile Broadband Network and the Internet.
