Abstract

Media content is provided for remote playback over a packet-based network. According to an example embodiment of the present invention, a host server authenticates remote users and further processes media content requests from authenticated remote users by directing or otherwise facilitating the delivery of requested media content from a user'"'"'s media content source to a remote playback device. The remote playback device is classified and the media content is selectively configured at one or both of the media content source and the host server in accordance with the classification, prior to delivery to the remote playback device. Communications among the host server, remote playback device and media content source are over the packet-based network.

2. The method of claim 1, wherein

the network is a public data network,

the plurality of registered-user media content sources include content sources operated by different users coupled to the public data network at disparate geographical locations,

the agent processor is a computer that is programmed to execute a program to establish the communication link over the public data network, and to facilitate the delivery of media content from at least one of the plurality of the media content sources,

the authentication of remote users sending media requests over the public data network is performed by authenticating different users for each content source based upon authentication criteria for the particular content source to which media requests are directed, and

the delivery of the requested media content is made over the public data network to the at least one remote playback device via the agent processors located at respective media content sources for which the users are authenticated.

3. The method of claim 1, further comprising:

establishing device classes for a plurality of remote playback devices, each of the device classes grouping one or more remote playback devices into a single class as a function of characteristics of the remote playback devices, and

classifying each remote playback device to which requested media content is delivered as a function of characteristics of the remote playback device.

4. The method of claim 1, further comprising:

associating device classes with media content configuration types and utilizing the association to facilitate the configuration of media content for playback at the at least one remote playback device.

5. The method of claim 1, further comprising:

storing device rules including device class descriptions and device classification rules for each device class, and providing the device rules for use in configuring media content for playback at the at least one remote playback device.

6. The method of claim 1, further comprising:

associating device classes with media content configuration types and providing a configuration file depicting the association to each agent processor, wherein each agent processor uses the configuration file and information characterizing a class for the at least one particular remote playback device to configure media content for playback at the at least one remote playback device.

7. The method of claim 1, further comprising:

classifying each remote playback device using information provided by a remote user.

8. The method of claim 1, further comprising:

classifying each remote playback device using information provided by a remote user,

facilitating the storage of information characterizing each remote playback device'"'"'s classification, and

utilizing the stored information to determine the remote playback device'"'"'s class for use in configuring media content for each of the remote playback devices.

9. The method of claim 1, further comprising:

classifying each remote playback device using information provided by a remote user and

sending class data identifying the classification to each of the remote playback devices, wherein the at least one remote playback device is configured to provide the classification to facilitate subsequent requests for media content delivery to the remote playback device.

10. The method of claim 1, further comprising:

configuring the requested media content as a function of a classification of the at least one remote playback device by configuring the media content in accordance with a wireless access protocol (WAP) stack running on the at least one remote playback device.

11. The method of claim 1, further comprising:

downloading configuration software to the agent processor; and

controlling the agent processor to implement the configuration software to configure requested media content for playback at the at least one remote playback device.

22. The method of claim 1, further comprising:

selective configuration of the requested media content as a function of classification rules for a device class to which the remote playback device is classified by selectively providing a portion of requested media content pertaining to subscription rules attributed to a subscription classification of the remote playback device.

23. The method of claim 1, further comprising:

selective configuration of the requested media content as a function of classification rules for a device class to which the remote playback device is classified by selectively decrypting requested media content for use at the remote playback device, based upon a playback classification of the remote playback device.

24. The method of claim 1, wherein the agent processor is a registered-user'"'"'s personal computer that is programmed to execute a software program to initiate the communication link over the network.

12. An apparatus comprising:

at least one processor; and

at least one memory, including computer program code for one or more programs, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following;

authenticate one or more users requesting media content delivery to one or more remote media playback devices;

associate device classes with a set of device classification rules;

classify each remote media playback device into one of the associated device classes;

deliver content from registered-user media content sources to the one or more remote media playback devices; and

deliver media content to an authenticated user at a remote media playback device as a function of both the device classification of the remote media playback device and the device classification rules associated with the device class.

13. The apparatus of claim 12, wherein the apparatus is further configured to provide a device rules document that describes device classes and device classification rules for the device classes,

to provide the device rules document to each agent processor, and

to use the device rules document and information identifying a class for a particular remote playback device to identify a configuration for media content to be delivered to the particular remote playback device.

14. The apparatus of claim 12, wherein the apparatus is further configured to provide a hypertext transfer protocol (HTTP) cookie to each classified remote media playback device, each HTTP cookie identifying the class of the remote media playback device to which it is provided.
