Methods, systems, and products self-identify an electronic device to a remote control. The remote control queries the electronic device, and the electronic device sends a response. A collision avoidance mechanism is invoked to determine if the response self-identified the electronic device.

1. A method of identification, comprising: receiving, by an electronic device, a query wirelessly sent from a remote control;determining, by the electronic device, an identifying response to the query that identifies the electronic device;retrieving, by the electronic device, a predetermined time established by a manufacturer;calculating, by the electronic device, a random response interval of time before sending the identifying response, the random response interval of time calculated by multiplying the predetermined time by a random number;counting down, by the electronic device, a first timer to expiration of the random response interval of time;wirelessly sending, by the electronic device, the identifying response after the expiration of the first timer at the random response interval of time;retrieving, by the electronic device, a maximum response time;counting down, by the electronic device, a second timer to the expiration of the maximum response time;monitoring, by the electronic device, for receipt of an acknowledgment sent from the remote control, the acknowledgement confirming self-identification of the electronic device to the remote control; anddetermining, by the electronic device, a failure of the self-identification in response to the expiration of the maximum response time without the receipt of the acknowledgement. 2. The method of claim 1, further comprising assigning a life to the random response interval of time. 3. The method of claim 2, further comprising determining the life has expired. 4. The method according to claim 3, further comprising recalculating the random response interval of time in response to the expiration of the life. 5. An electronic device, comprising: a processor; anda memory storing code that when executed causes the processor to perform operations, the operations comprising:receiving a query sent from a remote control;determining an identifying response to the query that identifies the electronic device;retrieving a random number;retrieving a predetermined time established by a manufacturer;calculating a random response interval of time before sending the identifying response, the random response interval of time calculated by multiplying the random number by the predetermined time;counting down a first timer to expiration of the random response interval of time;sending the identifying response after the expiration of the first timer at the random response interval of time;retrieving a maximum response time;counting down a second timer to the expiration of the maximum response time;monitoring for receipt of an acknowledgment sent from the remote control, the acknowledgement confirming self-identification of the electronic device to the remote control; anddetermining a failure of the self-identification in response to the expiration of the maximum response time without the receipt of the acknowledgement. 6. The system of claim 5, wherein the operations further comprise assigning a life to the random response interval of time. 7. The system of claim 6, wherein the operations further comprise determining the life has expired. 8. The system of claim 7, wherein the operations further comprise recalculating the random response interval of time in response to the expiration of the life. 9. A memory storing instructions that when executed cause a processor to perform operations, the operations comprising: receiving a query sent from a remote control;determining an identifying response to the query that identifies an electronic device;retrieving a random number;retrieving a predetermined time established by a manufacturer;calculating a random response interval of time before sending the identifying response, the random response interval of time calculated by multiplying the random number by the predetermined time;counting down a first timer to expiration of the random response interval of time;sending the identifying response after the expiration of the first timer at the random response interval of time;retrieving a maximum response time;counting down a second timer to the expiration of the maximum response time;monitoring for receipt of an acknowledgment sent from the remote control, the acknowledgement confirming self-identification of the electronic device to the remote control; anddetermining a failure of the self-identification in response to the expiration of the maximum response time without the receipt of the acknowledgement. 10. The memory of claim 9, wherein the operations further comprise assigning a life to the random response interval of time. 11. The memory of claim 10, wherein the operations further comprise determining the life has expired.
