Automatic determination of display device functionality
Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for automatically determining the functionality and capabilities of electronic components. Some embodiments operate by transmitting a command to the display device in question (sometimes called the device under test—DUT—herein) and monitoring the device. Then, it is determined whether an action by the display device was one of a set of proper responses to the command. If the action was proper, then it is determined that the display device supports the command set associated with the command. The command set may be the Consumer Electronics Control (CEC) set, although this disclosure is not limited to that example.
1. A method of automatically determining the functionality and capabilities of a device in a media system, comprising:
transmitting, by a media device, a command to the device;
receiving, by the media device, signals transmitted by the device, wherein the received signals include information responding to the command;
generating, by the media device, a fingerprint identifying the device based on the received signals, wherein the fingerprint comprises the information;
querying, by the media device, a crowdsource server using the fingerprint;
determining, by the media device and based on the querying, that the fingerprint does not exist in the crowdsource server; and
transmitting, by the media device, the fingerprint to the crowdsource server.
2. The method of claim 1 , wherein the transmitting comprises transmitting an audible control command to the device, and wherein the monitoring comprises using a microphone to detect volume changes made by the device in response to the audible control command.
3. The method of claim 1 , wherein the transmitting comprises transmitting a Consumer Electronics Control (CEC) command to the device over an HDMI link, and wherein the monitoring comprises monitoring traffic over the HDMI link for messages transmitted by the device, and further wherein the second determining comprises determining the device supports CEC.
4. The method of claim 1 , further comprising:
determining that the device supports a command set that comprises the command.
5. The method of claim 4 , further comprising:
receiving crowdsourced information from the crowdsource server specifying infrared (IR) signals corresponding to remote control commands supported by the device; and
transmitting the received crowdsourced information to a remote control that is not supported by the device,
wherein the remote control uses the received crowdsourced information to control the device.
6. The method of claim 2 , further comprising:
intercepting a command from a remote control to control the device, wherein the device does not support the remote control; and
transmitting a CEC command corresponding to the intercepted command to the device over the HDMI link, to thereby cause the device to perform the intercepted command.
7. A system for automatically determining the functionality and capabilities of a device in a media system, comprising:
a memory; and
at least one processor operatively coupled to the memory, the processor configured to:
transmit a command to the device;
receive signals transmitted by the device, wherein the received signals include information responding to the command;
generate a fingerprint identifying the device based on the received signals, wherein the fingerprint comprises the information;
query a crowdsource server using the fingerprint;
determine, based on the querying, that the fingerprint does not exist in the crowdsource server; and
transmit the fingerprint to the crowdsource server.
8. The system of claim 7 , wherein to transmit the processor is configured to transmit a Consumer Electronics Control (CEC) command to the device over an HDMI link, and wherein to monitor the processor is configured to monitor traffic over the HDMI link for messages transmitted by the device, and further wherein to determine that the device supports a command set the processor is configured to determine the device supports CEC.
9. The system of claim 7 , wherein the processor is further configured to:
receive crowdsourced information from the crowdsource server specifying infrared (IR) signals corresponding to remote control commands supported by the device; and
transmit the received crowdsourced information to a remote control that is not supported by the device,
wherein the remote control uses the received crowdsourced information to control the device.
10. The system of claim 7 , wherein the processor is further configured to:
intercept a command from a remote control to control the device, wherein the device does not support the remote control; and
transmit a CEC command corresponding to the intercepted command to the device over the HDMI link, to thereby cause the device to perform the intercepted command.
11. A non-transitory, tangible computer-readable device having instructions stored thereon that, when executed by at least one computing device, causes the at least one computing device to perform operations comprising:
transmitting a command to the device;
receiving signals transmitted by the device, wherein the received signals include information responding to the command;
generating a fingerprint identifying the device based on the received signals, wherein the fingerprint comprises the information;
querying a crowdsource server using the fingerprint;
determining, based on the querying, that the fingerprint does not exist in the crowdsource server; and
transmitting the fingerprint to the crowdsource server.
12. The non-transitory, tangible computer-readable device of claim 11 , wherein the transmitting comprises transmitting an audible control command to the device, and wherein the monitoring comprises using a microphone to detect volume changes made by the device in response to the audible control command.
13. The non-transitory, tangible computer-readable device of claim 11 , wherein the transmitting comprises transmitting a Consumer Electronics Control (CEC) command to the device over an HDMI link, and wherein the monitoring comprises monitoring traffic over the HDMI link for messages transmitted by the device, and further wherein the second determining comprises determining the device supports CEC.
14. The non-transitory, tangible computer-readable device of claim 11 , the operations further comprising:
determining that the device supports a command set that comprises the command.
15. The non-transitory, tangible computer-readable device of claim 14 , the operations further comprising:
receiving crowdsourced information from the crowdsource server specifying infrared (IR) signals corresponding to remote control commands supported by the device; and
transmitting the received crowdsourced information to a remote control that is not supported by the device,
wherein the remote control uses the received crowdsourced information to control the device.
16. The non-transitory, tangible computer-readable device of claim 12 , the operations further comprising:
intercepting a command from a remote control to control the device, wherein the device does not support the remote control; and
transmitting a CEC command corresponding to the intercepted command to the device over the HDMI link, to thereby cause the device to perform the intercepted command.
17. The method of claim 1 , wherein the transmitting comprises:
prompting a request for a model number of the device.
18. The method of claim 17 , further comprising:
receiving, responsive to the prompt, an image comprising a picture of the model number of the device from a remote control associated with the command.
19. The method of claim 17 , wherein the fingerprint further comprises a model number field and a CEC data field.
20. The method of claim 1 , wherein the adding comprises:
transmitting information corresponding to remote control commands supported by the device to the crowdsource server, wherein the commands comprise infrared (IR) signals.
