Abstract

One embodiment of the present invention sets forth 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.

First claim

We claim:

1. A method implemented by a controller device for directing a target device to play a first title, comprising:
discovering, by the controller device, the target device within a local network;
exchanging, by the controller device, unique identifiers with the target device to establish an association with the target device;
transmitting, by the controller device, a request to a content server machine to activate the target device, wherein the request indicates that the controller device is associated with the target device;
determining, by the controller device, whether the target device includes a service application through which the target device can communicate with the content server machine; and
if the target device includes the service application, then transmitting, by the controller device, one or more commands to the service application that direct the service application to stream the first title from the content server machine via a communication channel established between the target device and the content server machine.

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

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 comprises receiving a unicast message from the target device in response to the multicast message.

5. The method of claim 1 , further comprising:
determining, by the controller device, that the target device does not include the service application; and
transmitting, by the controller device, a command to a configuration manager that resides in the target device, wherein the command identifies the service application and provides a location where the service application can be accessed by the configuration manager.

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

7. The method of claim 6 , further comprising instructing, by the controller device, the installed service application to request activation from the content server machine based on the exchanged unique identifiers.

8. A non-transitory computer-readable medium including instructions that, when executed by a processor included in a controller device, cause the controller device to direct a target device to play a first title, by performing the steps of:
discovering the target device with a local network;
exchanging unique identifiers with the target device to establish an association with the target device;
transmitting a request to a content server machine to activate the target device, wherein the request indicates that the controller device is associated with the target device;
determining whether the target device includes a service application through which the target device can communicate with the content server machine; and
if the target device includes the service application, then transmitting one or more commands to the service application that direct the service application to stream the first title from the content server machine via a communication channel established between the target device and the content server machine.

9. The computer-readable medium of claim 8 , wherein each of the unique identifiers comprises a number that is unique to a particular service.

10. The computer-readable medium of claim 8 , wherein discovering comprises transmitting a multicast message to all devices in the local network.

11. The computer-readable medium of claim 10 , wherein discovering comprises receiving a unicast message from the target device in response to the multicast message.

12. The computer-readable medium of claim 8 , further comprising:
determining that the target device does not include the service application; and
transmitting a command to a configuration manager that resides in the target device, wherein the command identifies the service application and provides a location where the service application can be accessed by the configuration manager.

13. The computer-readable medium of claim 12 , further comprising causing the configuration manager to install the service application on the target device once the service application has been located and accessed.

14. The computer-readable medium of claim 13 , further comprising instructing the installed service application to request activation from the content server machine based on the exchanged unique identifiers.

15. A controller device configured to direct a target device to play a first title, the controller device comprising:
a network interface circuit configured to communicate with other devices within a local network; and
a processor coupled to the network interface and configured to:
discover the target device with the local network;
exchange unique identifiers with the target device to establish an association with the target device;
transmit a request to a content server machine to activate the target device, wherein the request indicates that the controller device is associated with the target device;
determine whether the target device includes a service application through which the target device can communicate with the content server machine; and
if the target device includes the service application, then transmit one or more commands to the service application that direct the service application to stream the first title from the content server machine via a communication channel established between the target device and the content server machine.

16. The controller device of claim 15 , wherein the target device does not include the service application, and the processor is further configured to transmit a command to a configuration manager that resides in the target device, wherein the command identifies the service application and provides a location where the service application can be accessed by the configuration manager.

17. The controller device of claim 16 , wherein the processor is further configured to:
cause the configuration manager to install the service application on the target device once the service application has been located and accessed; and
instruct the installed service application to request activation from the content server machine based on the exchanged unique identifiers.

18. The controller device of claim 15 , wherein to discover the target device, the processor is further configured to:
transmit a multicast message to all devices in the local network; and
receive a unicast message from the target device in response to the multicast message.
