Abstract

Systems and methods may involve minimizing interference when synchronization information is being transmitted from multiple sources. This may include receiving a trigger signal wherein the trigger signal includes a timing parameter to be used by a user device to synchronize with a content platform, and transmitting a synchronization signal having a transmitter identification and the timing parameter.

Claims

1. A system comprising:

a content platform including,

a content engine to broadcast content having a first processor and a first memory;

a display device to display the content; and

a transmitter device to transmit a synchronization signal, wherein the synchronization signal includes a transmitter identification and a timing parameter; and

a user device including a receiver device to receive the synchronization signal, to utilize the transmitter identification to determine the identity of the content platform with respect to one or more other content platforms, and to utilize the timing parameter to synchronize with the content engine such that a synchronization signal from the content platform is received and a synchronization signal from the one or more other content platforms is disregarded to minimize interference due to synchronization information being transmitted from multiple sources.

2. The system of claim 1, wherein the transmitter device includes,

a transmitter device storage component to store the transmitter identification;

a number generator to generate a number generator number;

a counter to count a counter number;

a transmitter device compare component to compare the number generator number and the counter number; and

a transmitter to transmit the synchronization signal to the user device.

3. The system of claim 2, wherein the number generator number is generated pseudo-randomly.

4. The system of claim 2, wherein the transmitter device compare component generates a signal to direct the transmitter to transmit the synchronization signal to the user device.

5. The system of claim 1, wherein the receiver device includes,

a receiver sensor to detect the synchronization signal;

a receiver to extract the transmitter identification and the timing parameter from the synchronization signal;

a receiver device storage component to store a match identification; and

a receiver device compare component to compare the transmitter identification and the match identification to validate the synchronization signal.

6. The system of claim 5, wherein the receiver device further includes a control system to synchronize the user device with the content engine.

7. The system of claim 5, wherein a cyclic redundancy check is executed to validate the synchronization signal.

8. An apparatus comprising:

a transmitter device storage component to store a transmitter identification of a content platform;

a number generator to generate a number generator number;

a counter to count a counter number;

a transmitter device compare component to compare the number generator number and the counter number; and

a transmitter to transmit a synchronization signal for the content platform to a user device such that the synchronization signal for the content platform is received and a synchronization signal for one or more other content platforms is disregarded to minimize interference due to synchronization information being transmitted from multiple sources.

9. The apparatus of claim 8, wherein the synchronization signal includes a transmitter identification and a timing parameter.

10. The apparatus of claim 8, wherein the transmitter device compare component is to generate a signal to direct the transmitter to transmit the synchronization signal to the user device.

11. The apparatus of claim 8, wherein the number generator number is generated pseudo-randomly.

12. The apparatus of claim 8, wherein the number generator number is generated randomly.

13. A method comprising:

receiving a trigger signal, wherein the trigger signal includes a timing parameter to be used by a user device to synchronize with a content platform;

generating a number generator number;

counting a counter number;

comparing the number generator number and the counter number; and

transmitting a synchronization signal including a transmitter identification and the timing parameter to determine the identity of the content platform with respect to one or more other content platforms such that a synchronization signal for the content platform is received and a synchronization signal for one or more other content platforms is disregarded to minimize interference due to synchronization information being transmitted from multiple sources.

14. The method of claim 13, further including,

detecting the synchronization signal;

and

comparing the transmitter identification with a match identification.

15. The method of claim 14, further including,

synchronizing a user device utilizing the timing parameter.

16. The method of claim 15, wherein the synchronization signal is transmitted if the number generator number and the counter number are the same.

17. The method of claim 14, further including,

validating the synchronization signal if the transmitter identification matches the match identification.

18. The method of claim 14, wherein the number generator generates the number generator number pseudo-randomly.

19. The method of claim 13, further including,

extracting the transmitter identification and the timing parameter from the synchronization signal.

20. The method of claim 13, further including,

forwarding the timing parameter to a control system to synchronize a user device.
