Abstract

An electronic device is configured to facilitate the transfer of customized multimedia content. A controller encapsulates multimedia payload using data stored in memory and transfers the encapsulated multimedia content to a remote device over a communications interface. The data may include one or more user-selected start positions for the multimedia content, each being associated with a user-specified predetermined event. The device may also receive encapsulated multimedia content, and use the encapsulated information to update local memory. This allows the receiving electronic device to use the multimedia content as specified by the sending user without requiring the user to redefine the user-selected start positions and their associated predetermined events.

Claims

1. A wireless communications device comprising:

a communications interface to communicatively connect the wireless communications device to a remote device;

a memory to store multimedia content;

application logic stored in the memory; and

a controller communicatively connected to the memory and the communications interface, and configured to execute the application logic to;

generate an encapsulated data structure comprising the multimedia content and one or more pointers, each pointer identifying a user-selected start position for the multimedia content; and

transmit the encapsulated data structure to the remote device.

2. The wireless communications device of claim 1 wherein the encapsulated data structure includes an identifier section comprising an indicator that identifies a predetermined format of the encapsulated data structure.

3. The wireless communications device of claim 2 wherein the encapsulated data structure further includes a tag section comprising the one or more pointers.

4. The wireless communications device of claim 3 wherein the tag section further comprises one or more predetermined events, each being associated with a corresponding one of the pointers.

5. The wireless communications device of claim 1 wherein the controller is configured to generate the encapsulated data structure based on information retrieved from a list stored in the memory.

6. The wireless communications device of claim 5 wherein the list comprises a contact list that includes the one or more pointers and an identifier that associates each pointer with a predetermined event.

7. A method of transferring multimedia content between wireless communications devices, the method comprising:

storing multimedia content in a memory of a wireless communications device;

storing one or more pointers in the memory, each pointer identifying a user-selected start position for the multimedia content;

generating an encapsulated data structure including the multimedia content and the one or more pointers; and

transmitting the encapsulated data structure to a remote device communicatively connected to the wireless communications device.

8. The method of claim 7 wherein the generating an encapsulated data structure comprises generating an identifier section to include an indicator that identifies a predetermined format of the encapsulated data structure.

9. The method of claim 8 further comprising generating a tag section to include the one or more pointers.

10. The method of claim 9 further comprising generating the tag section to include an identifier for each pointer, each identifier associating a corresponding pointer to a predetermined event.

11. The method of claim 10 further comprising generating a header section to include data that identifies an encoding scheme of the multimedia content.

12. The method of claim 7 wherein generating an encapsulated data structure comprises generating the encapsulated data structure based on information retrieved from a list stored in the memory of the wireless communications device.

13. The method of claim 12 wherein the list comprises a contact list that includes the one or more pointers, each having an identifier associates the corresponding pointer to a predetermined event.

14. A wireless communications device comprising:

a communications interface to communicatively connect the wireless communications device to a remote device;

a memory;

application logic stored in the memory; and

a controller communicatively connected to the memory and the communications interface, and configured to execute the application logic to;

receive an encapsulated data structure comprising multimedia content and one or more pointers, each pointer identifying a user-selected start position for the multimedia content; and

render the multimedia content beginning from one of the pointers.

15. The method of claim 14 wherein the controller is further configured to update the memory to include the one or more pointers.

16. The wireless communications device of claim 14 wherein the controller is configured to validate the encapsulated data structure responsive to receiving the encapsulated data structure.

17. The wireless communications device of claim 16 wherein the controller is configured to compare an indicator in an identifier section of the encapsulated data structure to a predetermined identifier stored in the memory.

18. The wireless communications device of claim 14 wherein the controller is configured to retrieve the one or more pointers from a tag section of the encapsulated data structure responsive to validating the encapsulated data structure.

19. The wireless communications device of claim 18 wherein the controller is further configured to retrieve one or more identifiers from the tag section, each identifier being associated with a corresponding pointer and comprising information that relates the corresponding pointer to a predetermined event.

20. The wireless communications device of claim 19 further comprising prompting the user to edit at least one of the pointers and the identifiers.

21. The wireless communications device of claim 19 wherein the controller is further configured to update a list stored in the memory to include the pointers and the associated identifiers.

22. The wireless communications device of claim 21 wherein the list comprises a contact list.

23. A method of transferring multimedia content between wireless communications devices, the method comprising:

receiving an encapsulated data structure over a communications interface at a wireless communications device, the encapsulated data structure comprising multimedia content and one or more pointers that identify user-selected start positions for the multimedia content;

validating the encapsulated data structure based on an identifier included with the encapsulated data structure;

retrieving the one or more pointers from the encapsulated data structure based on the validation; and

rendering the multimedia content beginning from a starting point specified by one of the pointers.

24. The method of claim 23 wherein validating the encapsulated data structure comprises comparing an indicator retrieved from an identifier section of the encapsulated data structure to a predetermined identifier stored in the memory.

25. The method of claim 23 further comprising retrieving the one or more pointers from a tag section of the encapsulated data structure.

26. The method of claim 25 further comprising retrieving one or more predetermined events from the tag section, each predetermined event being linked to a corresponding pointer.

27. The method of claim 26 further comprising altering at least one of the pointers and the predetermined event retrieved from the tag section responsive to user input.

28. The method of claim 26 further comprising updating a list stored in the memory to include the pointers and the associated predetermined events.

29. The method of claim 28 wherein the list comprises a contact list.
