Abstract

One embodiment of the present invention sets forth a technique for managing playback of digital content on two or more different playback devices. A playback device designated as a controller is associated with a playback device designated as a playback target. Association is implemented via a local network discovery protocol. The controller issues commands to the target, which then streams digital content directly from a content server. The controller is able to separately stream related digital content for independent, but synchronized playback. Server mediated operations, such as device activation and application installation, are advantageously enabled by explicit association between the controller and the target.

Claims

1. A method for configuring a target device to play a selected title, the method comprising:

discovering a controller device within a local network;

exchanging unique identifiers with the controller device to establish an association with the controller device;

receiving a query from the controller device to determine whether a service application is available on the target device; and

if the service application is available, then notifying the controller device that target device is configured to play the selected title, or

if the service application is not available, then performing one or more operations to install the service application.

2. The method of claim 1, wherein each of the unique identifiers comprises a number that is universally unique to a particular device.

3. The method claim 1, wherein determining whether the service application is available comprises searching a list of available applications on the target device.

4. The method of claim 1, wherein the one or more operations comprise retrieving an installation package from a content server and extracting the service application from the installation package.

5. The method of claim 4, wherein the one or more operations further comprise storing the service application as an executable file on the target device, and adding the service application to a list of available applications on the target device.

6. The method of claim 5, further comprising receiving an activation command from the controller device, and, in response, requesting activation from the content server based on the exchanged unique identifiers.

7. The method of claim 1, wherein discovering comprises receiving a multicast message from the controller device.

8. The method of claim 6, wherein discovering comprises transmitting a unicast message to the controller device in response to the multicast message.

9. A computer-readable medium including instructions that, when executed by a processing unit, cause the processing unit to configure a target device to play a selected title, by performing the steps of:

discovering a controller device within a local network;

exchanging unique identifiers with the controller device to establish an association with the controller device;

receiving a query from the controller device to determine whether a service application is available on the target device; and

if the service application is available, then notifying the controller device that target device is configured to play the selected title, or

if the service application is not available, then performing one or more operations to install the service application.

10. The computer-readable medium of claim 9, wherein each of the unique identifiers comprises a number that is universally unique to a particular device.

11. The computer-readable medium claim 9, wherein determining whether the service application is available comprises searching a list of available applications on the target device.

12. The computer-readable medium of claim 9, wherein the one or more operations comprise retrieving an installation package from a content server and extracting the service application from the installation package.

13. The computer-readable medium of claim 12, wherein the one or more operations further comprise storing the service application as an executable file on the target device, and adding the service application to a list of available applications on the target device.

14. The computer-readable medium of claim 13, further comprising receiving an activation command from the controller device, and, in response, requesting activation from the content server based on the exchanged unique identifiers.

15. The computer-readable medium of claim 9, wherein discovering comprises receiving a multicast message from the controller device.

16. A target device configured to play a selected title, the target device comprising:

a network interface circuit configured to communicate with other devices within a local network; and

a processing unit coupled to the network interface and configured to;

discover a controller device within the local network;

exchange unique identifiers with the controller device to establish an association with the controller device;

receive a query from the controller device to determine whether a service application is available on the target device; and

if the service application is available, then notify the controller device that target device is configured to play the selected title, or

if the service application is not available, then perform one or more operations to install the service application.

17. The target device of claim 16, wherein each of the unique identifiers comprises a number that is universally unique to a particular device.

18. The target device of claim 16, wherein to discover, the processing unit is further comprised to:

receive a multicast message from the controller device; and

transmit a unicast message to the controller device in response to the multicast message.

19. The target device of claim 16, wherein the processing unit is further configured to receive an activation command from the controller device, and, in response, request activation from a content server based on the exchanged unique identifiers.

20. The target device of claim 16, wherein to perform the one or more operations, the processing unit is further configured to:

retrieve an installation package from a content server;

extract the service application from the installation package;

store the service application as an executable file on the target device; and

add the service application to a list of available applications on the target device.
