Abstract

A single Point of Recordation Terminal (PORT) is disclosed. The PORT is configured to detect one or more events of interest, generate one or more representations of the event and establish the timing relationship among the multiple representations of the event of interest. The PORT is further configured to associate a unique ID of the PORT with the representations, encrypt and upload the representations to the cloud.

Claims

1. A method for generating and storing an asset from a Point of Recordation Terminal (PORT), comprising:

collecting a unique identification of the PORT;

determining an event of interest by the PORT;

generating multiple representations of the event of interest determined by the PORT, wherein the multiple representations include both video and still images of the event derived from the video;

identifying timing relationship between the multiple representations of the event of interest determined by the PORT;

associating the unique identification of the PORT with the multiple representations of the event of interest determined by the PORT;

encrypting and uploading the multiple representations of the event of interest with the unique identification of the PORT for cloud storage.

2. The method of claim 1 wherein the asset is an encrypted digital file.

3. The method of claim 1 further comprising:

determining and encoding a type of event.

4. The method of claim 1 further comprising:

computing and storing a digital signature.

5. The method of claim 1 further comprising:

determining and storing a preroll before the start of the event.

6. The method of claim 1 further comprising:

determining and storing a postroll after the end of the event.

7. The method of claim 1 further comprising:

deriving a metadata value for the number of moving objects.

8. A method for generating and transmitting a reference of an event of interest, comprising:

determining the event of interest by a Point of Recordation Terminal (PORT);

composing a reference by selecting a representative frame of a video of the event of interest generated by the PORT;

reading and encoding a time of day of the event of interest by the PORT;

storing a type of the reference;

identifying and encoding an offset of the reference relative to the time of day of the event;

encrypting and transmitting the reference with the offset and the time of day of the event.

9. The method of claim 8 wherein a reference is an encrypted digital file.

10. The method of claim 8 further comprising:

determining and storing a digital signature.

11. The method of claim 8 further comprising:

deriving a low resolution, scaled still image representative of the event of interest.

12. The method of claim 8 further comprising:

reading and storing a size of the multiple representations of the event of interest.

13. The method of claim 8 further comprising:

deriving a meta-data value for speed of moving object.

14. The method of claim 8 further comprising:

selecting a high resolution digital photograph from an image sequence of the event of interest,

converting the image sequence into a medium resolution video image sequence,

deriving a compressed, scaled, low resolution representation from the selected high resolution digital photograph.

15. A point of recordation terminal (PORT) comprising:

an asset &

event capture circuit configured to;

determine the event of interest by a Point of Recordation Terminal (PORT);

generate a video stream of the event of interest generated by the PORT;

an encryption circuit,

wherein the encryption circuit comprises;

an input for reading a unique camera identification key,

an input for reading a video stream from the formatting circuit,

a processor for encoding the video stream with time, date, and the unique camera identification key, and

an output for writing the resultant encoded video stream to the archive store.

16. A point of recordation terminal (PORT) comprising:

an asset &

event capture circuit configured to;

determining an event of interest by the PORT;

capturing multiple representations of the event of interest determined by the PORT, wherein the multiple representations include both video and still images of the event derived from the video;

identifying timing relationship between the multiple representations of the event of interest determined by the PORT;

associating a unique identification of the PORT with the multiple representations of the event of interest determined by the PORT;

an encryption circuit configured to encrypt the captured representations of the event of interest prior to transmission;

a network interface configured to upload the multiple representations of the event of interest with the unique identification of the PORT for cloud storage.

17. The apparatus of claim 16 further comprising:

an archive store coupled to the encryption circuit whereby captured assets and references are stored in encrypted form into the archive store.

18. The apparatus of claim 16 wherein the encryption circuit is uniquely associated with the specific PORT by cryptographic operation.

19. The apparatus of claim 18 wherein the encryption circuit indicates the time and date of the event of interest by cryptographic operation on the assets.

20. The apparatus of claim 17 wherein the network interface is configured to:

transmit a reference immediately while storing an asset into the archive store;

temporarily store the transmitted reference and storing it to the archive store in case the transmission fails,

detect when the transmission is restored, and

retransmit the reference.
