Systems and methods for transmitting and receiving large objects via digital radio broadcast
View Patent ↗Methods and systems for transmitting and receiving large objects via digital radio broadcast involve retrieving an object and an object description; assigning a unique identifier to the object; segmenting the object into a plurality of fragments; generating at least one long message having selected ones of the fragments and a long header including the unique identifier and the object description; generating at least one short message having selected ones of the fragments and a short header including the unique identifier; and communicating the at least the long message or the short message to a digital radio broadcast transmitter. In accordance with certain embodiments, reassembly of the object can begin with either a long message or a short message.
1. A method of preparing a large object for digital radio broadcast transmission comprising the steps of:
determining whether an object and an object description have been received;
assigning a unique identifier to an object that has been received in response to the determining;
segmenting the object into a plurality of fragments;
generating at least one long message having selected ones of the fragments and a long header comprising the unique identifier and the object description;
generating at least one short message having selected ones of the fragments and a short header comprising the unique identifier; and
communicating the at least one long message and the at least one short message to a digital radio broadcast transmitter,
wherein more short messages than long messages are generated or more long messages than short messages are generated.
2. The method of claim 1 wherein the object description includes at least one of a file name, a version and a file size.
3. The method of claim 1 wherein the object description includes a discard time.
4. The method of claim 3 wherein the fragments are discarded at the discard time.
5. The method of claim 1 wherein the object description includes a Multipurpose Internet Mail Extensions hash.
6. The method of claim 1 wherein the at least one long header and the at least one short header include a repetition counter, wherein the plurality of fragments is repeatedly transmitted based on the repetition counter.
7. The method of claim 1 wherein the at least one long header includes a relative position of a first of the selected ones of the fragments.
8. The method of claim 1 wherein the at least one short header includes a relative position of a first of the selected ones of the fragments.
9. The method of claim 1 wherein more short messages than long messages are generated.
10. The method of claim 1 wherein more long messages than short messages are generated.
11. A non-transitory, tangible computer readable medium for preparing a large object for digital radio broadcast transmission comprising computer program instructions adapted to cause a processing system to execute steps comprising:
determining whether an object and an object description have been received;
assigning a unique identifier to an object that has been received in response to the determining;
segmenting the object into a plurality of fragments;
generating at least one long message having selected ones of the fragments and a long header comprising the unique identifier and the object description;
generating at least one short message having selected ones of the fragments and a short header comprising the unique identifier; and
communicating the at least one long message and the at least one short message to a digital radio broadcast transmitter,
wherein more short messages than long messages are generated or more long messages than short messages are generated.
12. The non-transitory, tangible computer readable medium of claim 11 , wherein the object description includes at least one of a file name, a version and a file size.
13. The non-transitory, tangible computer readable medium of claim 11 , wherein the object description includes a discard time.
14. The non-transitory, tangible computer readable medium of claim 13 , comprising program instructions for causing the processing system to discard the plurality of fragments at the discard time.
15. The non-transitory, tangible computer readable medium of claim 11 , wherein the at least one long header and the at least one short header include a repetition counter, wherein the plurality of fragments is repeatedly transmitted based on the repetition counter.
16. The non-transitory, tangible computer readable medium of claim 11 , wherein the at least one long header includes a relative position of a first of the selected ones of the fragments.
17. The non-transitory, tangible computer readable medium of claim 11 , wherein the at least one short header includes a relative position of a first of the selected ones of the fragments.
18. The non-transitory, tangible computer readable medium of claim 11 , wherein more short messages than long messages are generated.
19. The non-transitory, tangible computer readable medium of claim 11 , wherein more long messages than short messages are generated.
20. A system for preparing a large object for digital radio broadcast transmission comprising:
a processing system; and
a memory coupled to the processing system, wherein the processing system is configured to execute steps comprising:
determining whether an object and an object description have been received;
assigning a unique identifier to an object that has been received;
segmenting the object into a plurality of fragments;
generating at least one long message having selected ones of the fragments and a long header comprising the unique identifier and the object description;
generating at least one short message having selected ones of the fragments and a short header comprising the unique identifier; and
communicating the at least one long message and the at least one short message to a digital radio broadcast transmitter,
wherein more short messages than long messages are generated or more long messages than short messages are generated.
21. The system of claim 20 , wherein the object description includes at least one of a file name, a version and a file size.
22. The system of claim 20 , wherein the object description includes a discard time.
23. The system of claim 22 , wherein the processing system is configured to discard the plurality of fragments at the discard time.
24. The system of claim 20 , wherein the at least one long header and the at least one short header include a repetition counter, wherein the plurality of fragments is repeatedly transmitted based on the repetition counter.
25. The system of claim 20 , wherein the at least one long header includes a relative position of a first of the selected ones of the fragments.
26. The system of claim 20 , wherein the at least one short header includes a relative position of a first of the selected ones of the fragments.
27. The system of claim 20 , wherein more short messages than long messages are generated.
28. The system of claim 20 , wherein more long messages than short messages are generated.
