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, comprising:

discovering one or more target devices within a local network;

exchanging at least one unique identifier with each of the one or more target devices to establish a set of associations with the one or more target devices;

transmitting information describing the set of associations with the one or more target devices to a content server machine;

in response to a selection of a first target device to control, determining whether a playback application is installed on the first target device, wherein the first target device is included in the one or more target devices; and

if the first target device includes the playback application, then processing one or more user interface commands related to playing back content stored on the content server machine, or

if the first target device does not include the playback application, then transmitting installation information to the first target device that allows the first target device to download the playback application.

2. The method of claim 1, wherein the at least one unique identifier associated with a target device establishes a unique context for interaction between the target device and a controller device.

3. The method of claim 1, wherein discovering comprises transmitting a multicast message to all devices in the local network.

4. The method of claim 3, wherein discovering further comprises receiving a unicast message from each of the one or more target devices in response to the multicast message.

5. The method of claim 1, wherein transmitting installation to the first target device comprises transmitting a command to a configuration manager that resides within the first target device, wherein the command identifies the playback application and provides a location where the playback application can be accessed by the configuration manager.

6. The method of claim 5, further comprising causing the configuration manager to install the playback application on the first target device once the playback application has been located and accessed.

7. The method of claim 6, further comprising instructing the installed playback application to request activation from the content server machine based on the at least one unique identifier associated with the first target device.

8. The method of claim 1, wherein the set of associations allows the content server machine to perform mediated operations between a controller device and the one or more target devices.

9. The method of claim 8, wherein each association included in the set of association comprises a universally unique identifier or unique service name pair that corresponds to one of the target devices included in the one or more target devices.

10. A non-transitory computer-readable medium including instructions that, when executed by a processor included in a controller device, cause the processor to perform the steps of:

exchanging at least one unique identifier with each of one or more target devices to establish a set of associations with the one or more target devices;

transmitting information describing the set of associations with the one or more target devices to a content server machine;

in response to a selection of a first target device to control, determining whether a playback application is installed on the first target device, wherein the first target device is included in the one or more target devices; and

if the first target device includes the playback application, then processing one or more user interface commands related to playing back content stored on the content server machine, or

if the first target device does not include the playback application, then transmitting installation information to the first target device that allows the first target device to download the playback application.

11. The non-transitory computer-readable medium of claim 10, wherein the at least one unique identifier associated with a target device establishes a unique context for interaction between the target device and a controller device.

12. The non-transitory computer-readable medium of claim 10, further comprising discovering the one or more target devices by transmitting a multicast message to all devices in the local network, and receiving a unicast message from each of the one or more target devices in response to the multicast message.

13. The non-transitory computer-readable medium of claim 10, further comprising displaying a list representing the one or more target devices.

15. The non-transitory computer-readable medium of claim 10, wherein transmitting installation to the first target device comprises transmitting a command to a configuration manager that resides within the first target device, wherein the command identifies the playback application and provides a location where the playback application can be accessed by the configuration manager.

16. The non-transitory computer-readable medium of claim 15, further comprising causing the configuration manager to install the playback application on the first target device once the playback application has been located and accessed.

17. The non-transitory computer-readable medium of claim 16, further comprising instructing the installed playback application to request activation from the content server machine based on the at least one unique identifier associated with the first target device.

18. The non-transitory computer-readable medium of claim 10, wherein the set of associations allows the content server machine to perform mediated operations between a controller device and the one or more target devices.

19. The non-transitory computer-readable medium of claim 18, wherein each association included in the set of association comprises a universally unique identifier or unique service name pair that corresponds to one of the target devices included in the one or more target devices.

20. The non-transitory computer-readable medium of claim 10, wherein the one or more user interface commands include at least one of a search command to be executed by the content server machine and a playback command to be executed by the first target device.

21. The non-transitory computer-readable medium of claim 20, wherein processing the one or more user interface commands comprises at least one of transmitting a search query to the content server machine based on the search command and transmitting the playback command to the first target device.

14. The non-transitory computer-readable medium, herein the first target device is selected from the list.

22. A controller device, comprising:

a memory storing instructions; and

a processor that is coupled to the memory and, when executing the instructions, is configured to;

exchange at least one unique identifier with each of one or more target devices to establish a set of associations with the one or more target devices;

transmit information describing the set of associations with the one or more target devices to a content server machine;

in response to a selection of a first target device to control, determine whether a playback application is installed on the first target device, wherein the first target device is included in the one or more target devices; and

if the first target device includes the playback application, then process one or more user interface commands related to playing back content stored on the content server machine, or

if the first target device does not include the playback application, then transmit installation information to the first target device that allows the first target device to download the playback application.
