Abstract

A scalable architecture is disclosed for delivery of real-time information over a communications network. Embedded into the architecture is a control mechanism that provides for the management and administration of users who are to receive the real-time information. In the preferred embodiment, the information being delivered is high-quality audio. However, it could also be video, graphics, text or any other type of information that can be transmitted over a digital network. Preferably, there are multiple channels of information available simultaneously to be delivered to users, each channel consisting of an independent stream of information. A user chooses to tune in or tune out a particular channel, but does not choose the time at which the channel distributes its information. Advantageously, interactive (two-way) information can be incorporated into the system, multiple streams of information can be integrated for delivery to a user, and certain portions of the information being delivered can be tailored to the individual user.

in response to the first request, receiving information identifying a second server selected from a plurality of servers each capable of providing the selected media to the client, wherein the second server is different from the first server;

establishing a second network connection with the second server, wherein the second network connection is an Internet Protocol (IP) connection;

via the second network connection, transmitting to the second server a second request comprising a request for the selected media along with extra information for playing the selected media;

in response to the second request, receiving a response that conforms to capabilities of the client, wherein the response includes the selected media; and

playing the selected media.

2. The method of claim 1, further comprising, prior to transmitting the second request to the second server, requesting authorization to receive the response that conforms to the capabilities of the client.

3. The method of claim 1, further comprising:

at the client, obtaining a key; and

prior to playing the selected media, validating the key.

4. The method of claim 1, further comprising, while receiving the selected media, transmitting respective information regarding reception of the selected media.

5. The method of claim 1, further comprising transmitting, to a respective server that is responsible for receiving logging information, respective logging information related to delivery of the selected media to the client.

6. The method of claim 1, further comprising, while receiving the selected media:

detecting packet loss; and

in response to detecting the packet loss, requesting a different bitrate version of the selected media.

7. The method of claim 1, further comprising, while receiving the selected media:

transmitting, to a respective server that is responsible for controlling delivery of the selected media to the client, respective information indicating packet loss; and

in response to transmitting the respective information, receiving a different bitrate version of the selected media.

8. The method of claim 1, wherein the information identifying the second server includes an ordered list of servers including the second server and one or more other servers capable of providing the selected media to the client.

9. The method of claim 8, further comprising selecting the second server from the ordered list of servers by selecting a server from the beginning of the ordered list of servers.

10. The method of claim 1, further comprising, prior to establishing the first network connection with the first server:

establishing a prior network connection with a third server different from the first and second servers, wherein the prior network connection is an Internet Protocol (IP) connection;

via the prior network connection, transmitting to the third server a prior request for information identifying one or more servers configured to identify servers capable of providing the selected media to the client; and

in response to the prior request, receiving information identifying the first server, selected from a plurality of servers each configured to identify servers capable of providing the selected media to the client.

11. The method of claim 10, wherein:

the third server authorizes the client to receive information from the first server and the second server; and

in response to authorization by the third server, the client receives a token.

12. The method of claim 10, wherein the information identifying the first server includes an ordered list of servers including the first server and one or more other servers sorted based on system load.

13. The method of claim 12, further comprising selecting the first server from the ordered list of servers by selecting a server from the beginning of the ordered list of servers.

14. The method of claim 1, further comprising, via the first network connection, transmitting to the first server information enabling the first server to determine a version of the client application.

15. The method of claim 1, wherein the selected media includes a sequence of individual pieces of audio and/or video information.

26. The method of claim 14, wherein the information enabling the first server to determine the version of the client application is a version number.

27. The method of claim 1, wherein the response that conforms to the capabilities of the client conforms to a protocol that is compatible with both the client and the second server.

16. A non-transitory computer-readable storage medium storing instructions including instructions for a client application that, when executed by a client device, cause the client device to play media, the instructions comprising instructions for:

establishing a first network connection with a first server, wherein the first network connection is an Internet Protocol (IP) connection;

via the first network connection, transmitting to the first server

a first request comprising a unique identifier for selected media, wherein the selected media includes one or more of audio and video;

in response to the first request, receiving information identifying a second server selected from a plurality of servers each capable of providing the selected media to the client, wherein the second server is different from the first server;

establishing a second network connection with the second server, wherein the second network connection is an Internet Protocol (IP) connection;

via the second network connection, transmitting to the second server a second request comprising a request for the selected media along with extra information for playing the selected media;

in response to the second request, receiving a response that conforms to capabilities of the client, wherein the response includes the selected media; and

playing the selected media.

17. The non-transitory computer-readable storage medium of claim 16, further comprising instructions for, prior to transmitting the second request to the second server, requesting authorization to receive the response that conforms to the capabilities of the client.

18. The non-transitory computer-readable storage medium of claim 16, further comprising instructions for, while receiving the selected media, transmitting respective information regarding reception of the selected media.

19.
