Method of and system for mobile surveillance and event recording
A data-encoding system includes a source of unencoded data, and a first encoder interoperably coupled to the source, wherein the first encoder is adapted to receive the unencoded data, encode the unencoded data, and output encoded data at a first data rate. The data encoding system further includes a second encoder interoperably coupled to the source, wherein the second encoder is adapted to receive the unencoded data, encode the unencoded data, and output encoded data at a second data rate in which the second data rate exceeds the first data rate. This Abstract is provided to comply with rules requiring an Abstract that allows a searcher or other reader to quickly ascertain subject matter of the technical disclosure. This Abstract is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
1. A data-overflow-handling method comprising:
storing captured data to a first directory of a first data storage medium;
determining whether an event is being recorded;
responsive to a determination that an event is being recorded, storing an image of the stored data to a second directory of the first data storage medium;
determining whether a predefined capacity threshold of a second data storage medium has been exceeded;
responsive to a determination that the predefined capacity threshold has been exceeded, creating a third directory of the first data storage medium;
determining whether data in the second directory of the first data storage medium has not been stored to the second data storage medium;
responsive to a determination that data in the second directory of the first data storage medium has not been stored to the second data storage medium, storing any unstored data in the second directory of the second data storage medium;
determining whether the second directory contains finalization files; and
responsive to a determination that the second directory contains finalization files, finalizing the second data storage medium and providing a prompt to insert a third data storage medium.
2. The data-overflow-handling method of claim 1 , further comprising, responsive to insertion of the third data storage medium, checking for the third directory.
3. The data-overflow-handling method of claim 2 , further comprising:
determining whether data in the third directory of the first data storage medium has not been stored to the second data storage medium;
responsive to a determination that data in the third directory of the first data storage medium has not been stored to the second data storage medium, storing any unstored data in the third directory to the third data storage medium;
determining whether the third directory contains finalization files; and
responsive to a determination that the third directory contains finalization files, finalizing the second storage medium and providing a prompt to insert a fourth data storage medium.
4. The data-overflow-handling method of claim 1 , wherein:
the first data storage medium comprises a non-removable data storage medium; and
wherein the non-removable data storage medium comprises a hard drive.
5. The data-overflow-handling method of claim 1 , wherein the second data storage medium comprises a removable data storage medium.
6. The data-overflow-handling method of claim 5 , wherein the removable data storage medium comprises a digital video disc (DVD).
7. The data-overflow-handling method of claim 5 , wherein the removable data storage medium comprises a flash memory drive.
8. The data-overflow-handling method of claim 1 , wherein the third data storage medium comprises a removable data storage medium.
9. The data-overflow-handling method of claim 3 , wherein the fourth data storage medium comprises a removable data storage medium.
10. The data-overflow-handling method of claim 1 , further comprising:
responsive to a determination that the second directory contains no finalization files, returning to the step of determining whether data in the second directory of the first data storage medium has not been stored.
11. The data-overflow-handling method of claim 1 , wherein the captured data comprises at least one of audio data, video data, and metadata.
12. A data-overflow-handling computer system comprising:
a processor; and
a memory including instructions adapted to enable the computer system to perform the steps of:
storing captured data to a first directory of a first data storage medium;
determining whether an event is being recorded;
responsive to a determination that an event is being recorded, storing an image of the stored data to a second directory of the first data storage medium;
determining whether a predefined capacity threshold of a second data storage medium has been exceeded;
responsive to a determination that the predefined capacity threshold has been exceeded, creating a third directory of the first data storage medium;
determining whether data in the second directory of the first data storage medium has not been stored to the second data storage medium;
responsive to a determination that data in the second directory of the first data storage medium has not been stored to the second data storage medium, storing any unstored data in the second directory of the second data storage medium;
determining whether the second directory contains finalization files; and
responsive to a determination that the second directory contains finalization files, finalizing the second data storage medium and providing a prompt to insert a third data storage medium.
13. The computer system of claim 12 , further comprising instructions adapted to enable the computer system to perform the step of, responsive to insertion of the third data storage medium, checking for the third directory.
14. The computer system of claim 13 , further comprising instructions adapted to enable the computer system to perform the steps of:
determining whether data in the third directory of the first data storage medium has not been stored to the second data storage medium;
responsive to a determination that data in the third directory of the first data storage medium has not been stored to the second data storage medium, storing any unstored data in the third directory to the third data storage medium;
determining whether the third directory contains finalization files; and
responsive to a determination that the third directory contains finalization files, finalizing the second storage medium and providing a prompt to insert a fourth data storage medium.
15. The computer system of claim 12 , further comprising instructions adapted to enable the computer system to perform the step of:
responsive to a determination that the second directory contains no finalization files, returning to the step of determining whether data in the second directory of the first data storage medium has not been stored.
16. The computer system of claim 12 , wherein:
the first data storage medium comprises a non-removable data storage medium; and
wherein the non-removable data storage medium comprises a hard drive.
17. The computer system of claim 12 , wherein the second data storage medium comprises a removable data storage medium.
18. The computer system of claim 17 , wherein the removable data storage medium comprises a digital video disc (DVD).
19. The computer system of claim 17 , wherein the removable data storage medium comprises a flash memory drive.
20. The computer system of claim 12 , wherein the third data storage medium comprises a removable data storage medium.
21. The computer system of claim 14 , wherein the fourth data storage medium comprises a removable data storage medium.
22. The computer system of claim 12 , wherein the captured data comprises at least one of audio data, video data, and metadata.
