Abstract

A software based system for facilitating streaming of media files to a device over a wide area network (WAN) includes an agent process, an authentication process, a client services process and a client process. The agent process catalogs local media files and advises the authentication process of its availability on the WAN and the address at which it may be contacted. The client process contacts the client services process to obtain, after authenticating with it, the WAN address of the agent process and contacts the agent process to receive information or meta-data describing the media files available for streaming. The client process obtains information for forming a URI or playlist, that it then passes to a media player to request the stream over the WAN. Alternately, the client process may direct the agent process to pass the URL to another client process on, for example, the same local area network.

Claims

1. A set of stored instructions embodied on a medium that, when read by a programmable processor, results in the processor performing a process, the process comprising:

receiving a first communication over a wide area network (WAN), the first communication including connection information to connect to a first process via a proxy server on the WAN;

receiving a second communication from a second process, the second communication including the connection information for the first process and requesting meta data information collected by the first process;

forwarding the second communication including the connection information received from the second process to the first process via the proxy server on the WAN.

2. The set of stored instructions of claim 1, wherein the connection information comprises a unique identifier for use by the proxy server to identify the first process, and wherein the proxy server uses the unique identifier included in the second communication connection to forward the second communication to the first process.

3. The set of stored instructions of claim 1, wherein another communication from the second process includes a request for a streamed media file, the process further comprises:

receiving the streamed media file from the first process; and

forwarding the streamed media file to the second process.
