Automatic determination of display device functionality

A system comprising:

• a memory;
• and
• at least one processor coupled to the memory and configured to perform operations for determining functionality and capabilities of a device in a media system, the operations comprising:
• sending a first operational command to a target device;
• determining at least one of a match between information received from the target device in response to the operational command and valid response information, or a mismatch between the information received from the target device in response to the operational command and the valid response information, wherein:
• when the match between the information received from the target device in response to the operational command and the valid response information is determined, a second operational command is sent to the target device that causes the target device to perform the function, or
• when the mismatch between the information received from the target device in response to the operational command and the valid response information is determined, each operational command of a plurality of operational commands is incrementally sent to the target device until:
• a mismatch between additional information received from the target device in response to each operational command of the plurality of operational commands and the valid response information is determined, or
• a match between additional information received from the target device in response to at least one operational command of the plurality of operational commands and the valid response information is determined.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by at least one computing device, cause the at least one computing device to perform operations for determining functionality and capabilities of a device in a media system, the operations comprising:

• sending a first operational command to a target device;
• determining at least one of a match between information received from the target device in response to the operational command and valid response information, or a mismatch between the information received from the target device in response to the operational command and the valid response information, wherein:
• when the match between the information received from the target device in response to the operational command and the valid response information is determined, a second operational command is sent to the target device that causes the target device to perform the function, or
• when the mismatch between the information received from the target device in response to the operational command and the valid response information is determined, each operational command of a plurality of operational commands is incrementally sent to the target device until:
• a mismatch between additional information received from the target device in response to each operational command of the plurality of operational commands and the valid response information is determined, or
• a match between additional information received from the target device in response to at least one operational command of the plurality of operational commands and the valid response information is determined.
