Abstract

Apparatuses and methods may provide for technology that uses a wireless display docking over an infrastructure network by receiving, via a WiFi link, information associate with an infrastructure discovery of a receiver, using the information to discover the receiver via an infrastructure network i link, forming a connection with the receiver via the infrastructure network link, and streaming content to the receiver via the connection. In addition, receiver technology may emit a beacon signal via a WiFi link, form a connection with a client device via an infrastructure network link, and receive streamed content from the client device via the infrastructure network link.

Claims

1. A client apparatus comprising:

a receive manager to receive, via a WiFi link, information associated with an infrastructure discovery of a receiver;

a discovery controller communicatively coupled to the receive manager, the discovery controller to discover the receiver via an infrastructure network link;

a link manager communicatively coupled to the discovery controller, the link manager to form a connection with the receiver via the infrastructure network link; and

a content source communicatively coupled to the link manager, the content source to stream content to the receiver via the connection.

2. The apparatus of claim 1, wherein the receive manager is to listen for a specially formatted server set identifier (SSID) that the receiver emits, and receive connection information from the receiver, wherein the connection information includes an encoded string that identifies an IP address and port number for connectivity to the receiver.

3. The apparatus of claim 2, further includes a comparator to select the receiver from a plurality of receivers based on a strength of signal emitted by each receiver in the plurality of the receivers.

4. The apparatus of claim 2, wherein the receipt of the information associated with the infrastructure discovery of the receiver is to be performed at layer 2 of the WiFi link.

5. The apparatus of claim 1, wherein the link manager is to send a discovery request to identify the receiver, receive a discovery response that identifies a connection request port, connect to the receiver via the connection request port, and establish a real time streaming protocol (RTSP) connection between with the receiver.

6. The apparatus of claim 1, wherein the discovery and the connection with the receiver are to be formed at layer 3 of the infrastructure network.

7. At least one non-transitory computer readable storage medium comprising a set of instructions which, if executed by a computing device, cause the computing device to:

receive, via a WiFi link, information associated with an infrastructure discovery of a receiver;

use the information to discover the receiver via an infrastructure network link;

form a connection with the receiver via the infrastructure network link; and

stream content to the receiver via the connection.

8. The at least one non-transitory computer readable storage medium of claim 7, wherein the instructions if executed, further cause the computing device to:

listen for a specially formatted server set identifier (SSID) that the receiver emits;

receive connection information from the receiver, wherein the connection information includes an encoded string that identifies an IP address and port number for connectivity to the receiver.

9. The at least one non-transitory computer readable storage medium of claim 8, wherein the instructions if executed, further cause the computing device to select the receiver from a plurality of receivers based on a strength of signal emitted by each receiver in the plurality of the receivers.

10. The at least one non-transitory computer readable storage medium of claim 8, wherein the instructions if executed, further cause the computing device to receive the information associated with the infrastructure discovery of the receiver at layer 2 of the WiFi link.

11. The at least one non-transitory computer readable storage medium of claim 7, wherein the instructions if executed, further cause the computing device to:

send a discovery request to identify the receiver;

receive a discovery response that identifies a connection request port;

connect to the receiver via the connection request port;

establish a real time streaming protocol (RTSP) connection between with the receiver.

12. The at least one non-transitory computer readable storage medium of claim 7, wherein the instructions if executed, further cause the computing device to discover and form the connection at layer 3 of the infrastructure network.

13. A receiver apparatus comprising:

an emitter to emit a beacon signal via a WiFi link;

a link manager communicatively coupled to the emitter, the link manager to form a connection with a client device via an infrastructure network link; and

a receiver communicatively coupled to the link manger, the receiver to receive streamed content from the client device via the infrastructure network link.

14. The apparatus of claim 13, wherein the emitter is to transmit an encoded string that identifies an Internet Protocol address and port identifier for connectivity to the receiver.

15. The apparatus of claim 13, wherein the emitter is to emit the beacon signal at layer 2 of the WiFi link.

16. The apparatus of claim 13, wherein the link manager is to send a discovery response to the client device that includes a port identifier and start a real time streaming protocol (RTSP) connection with the client device via the infrastructure network link.

17. The apparatus of claim 16, wherein the discovery response is to further include a version identifier of an infrastructure protocol, a device identifier and available connection information.

18. The apparatus of claim 13, wherein the connection is to be formed at layer 3 of the infrastructure network.

19. At least one non-transitory computer readable storage medium comprising a set of instructions which, if executed by a computing device, cause the computing device to:

emit a beacon signal via a WiFi link;

form a connection with a client device via an infrastructure network link; and

receive streamed content from the client device via the infrastructure network link.

20. The at least one non-transitory computer readable storage medium of claim 19, wherein the instructions, if executed, further cause the computing device to transmit an encoded string that identifies an Internet Protocol address and port identifier for connectivity to the receiver.

21. The at least one non-transitory computer readable storage medium of claim 19, wherein the beacon signal is to be emitted at layer 2 of the WiFi link.

22. The at least one non-transitory computer readable storage medium of claim 19, wherein the instructions, if executed, further cause the computing device to:

send a discovery response that includes a port identifier; and

start a real time streaming protocol (RTSP) connection via the infrastructure network link.

23. The at least one non-transitory computer readable storage medium of claim 22, wherein the discovery response is to further include a version identifier of an infrastructure protocol, a device identifier and available connection information.

24. The at least one non-transitory computer readable storage medium of claim 19, wherein the connection is to be formed at layer 3 of the infrastructure network.
