Methods, systems, and products are disclosed for controlling an electronic device. A query is received at a remote control interface. A response to the query is determined. A random response interval of time is determined according to a collision avoidance mechanism. When the random response interval of time expires, then the response to the query is sent.

1. A method, comprising: receiving, at an electronic device, a query sent from a remote control;determining a response to the query to self-identify an electronic device to the remote control;retrieving a predetermined time from memory of the electronic device;generating a random number;multiplying the random number by the predetermined time to calculate a random response interval of time;counting down a first timer until expiration of the random response interval of time;sending the response from the electronic device when the random response interval of time expires;retrieving a maximum response time from memory of the electronic device;counting down a second timer until the expiration of the maximum response time;monitoring at the electronic device for receipt of an acknowledgment to the response, the acknowledgement confirming self-identification of the electronic device to the remote control;determining that the maximum response time expired before the receipt of the acknowledgement; anddetermining that the self-identification of the electronic device to the remote control has failed. 2. The method according to claim 1, further comprising calling a random number generator that determines the random number of the random response interval of time. 3. The method according to claim 1, further comprising assigning a life to the random response interval of time. 4. The method according to claim 3, further comprising recalculating the random response interval of time when the life expires. 5. The method according to claim 1, further comprising invoking the first timer that counts down until the expiration of the random response interval of time. 6. The method according to claim 1, wherein when the acknowledgment is received within the maximum response time, then further comprising obtaining a code from the acknowledgment. 7. The method according to claim 1, wherein when the acknowledgment is received within the maximum response time, then further comprising obtaining formatting from the acknowledgment. 8. A system, comprising: a processor; andmemory storing code that when executed causes the processor to perform operations, the operations comprising:receiving a query sent from a remote control;determining a response to the query to self-identify the system to the remote control;retrieving a predetermined time from the memory of the system;generating a random number;multiplying the random number by the predetermined time to calculate a random response interval of time;counting down a first timer until expiration of the random response interval of time;sending the response from the system when the random response interval of time expires;retrieving a maximum response time from the memory;counting down a second timer until the expiration of the maximum response time;monitoring for receipt of an acknowledgment to the response to the query, the acknowledgment confirming self-identification of the system to the remote control;determining the maximum response time expired before the receipt of the acknowledgement; anddetermining the self-identification failed. 9. The system according to claim 8, wherein the operations further comprise calling a random number generator that determines the random number of the random response interval of time. 10. The system according to claim 8, wherein the operations further comprise assigning a life to the random response interval of time. 11. The system according to claim 10, wherein the operations further comprise recalculating the random response interval of time when the life expires. 12. The system according to claim 8, wherein the operations further comprise invoking the first timer that counts down until the expiration of the random response interval of time. 13. The system according to claim 8, wherein the operations further comprise obtaining a code from the acknowledgment. 14. The system according to claim 8, wherein the operations further comprise obtaining formatting from the acknowledgment. 15. A computer readable memory storing computer-readable instructions that when executed cause a processor to perform operations, the operations comprising: receiving a query sent from a remote control;determining a response to the query to self-identify an electronic device to the remote control;retrieving a predetermined time from memory of the electronic device;generating a random number;multiplying the random number by the predetermined time to calculate a random response interval of time;counting down a timer until expiration of the random response interval of time;sending the response from the electronic device when the random response interval of time expires;retrieving a maximum response time from the memory of the electronic device;counting down a second timer until the expiration of the maximum response time;monitoring for receipt of an acknowledgment to the response to the query, the acknowledgment confirming self-identification of the electronic device to the remote control;determining the maximum response time expired before the receipt of the acknowledgement; anddetermining the self-identification failed. 16. The computer readable memory according to claim 15, wherein the operations further comprise calling a random number generator that determines the random number. 17. The computer readable memory according to claim 15, wherein the operations further comprise assigning a life to the random response interval of time. 18. The computer readable memory according to claim 17, wherein the operations further comprise recalculating the random response interval of time when the life expires. 19. The computer readable memory according to claim 15, wherein the operations further comprise obtaining a code from the acknowledgment. 20. The computer readable memory according to claim 15, wherein the operations further comprise obtaining formatting from the acknowledgment.
