Abstract

A method of transmitting selected regions of interest of digital video data at selected resolutions, including: capturing digital video; compressing the digital video into a sequence of individual high resolution JPEG 2000 frames and simultaneously extracting from the compressed high resolution JPEG 2000 frames a lower resolution; storing the individual high resolution JPEG 2000 frames in a storage device; creating a video sequence of the lower resolution representation; transmitting the video sequence of the lower resolution representation to a user; creating one or more video sequences of selected regions of interest at selected resolutions greater than the resolution of the video sequence of the lower resolution representation; transmitting one or more video sequences of selected regions of interest at selected resolutions; and repeating the prior two steps at incrementally increased resolutions until a desired resolution of the selected region of interest is reached according to a viewing objective.

Claims

1. A method of transmitting selected regions of interest of digital video data at selected resolutions, comprising the steps of:

a) capturing digital video;

b) compressing the digital video into a sequence of individual high resolution JPEG 2000 frames and simultaneously extracting from the compressed high resolution JPEG 2000 frames a lower resolution representation of each of the individual high resolution JPEG 2000 frames;

c) storing the individual high resolution JPEG 2000 frames in a storage device;

d) creating a video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames;

e) transmitting the video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames to a user;

f) creating one or more video sequences of selected regions of interest at selected resolutions greater than the resolution of the video sequence of the lower resolution representation;

g) transmitting one or more video sequences of selected regions of interest at selected resolutions; and

h) repeating steps (f) and (g) at incrementally increased resolutions until a desired resolution of the selected region of interest is reached according to a viewing objective.

2. The method claimed in claim 1, wherein the user selects the regions of interest and the selected resolution.

3. The method claimed in claim 1, wherein selection of the regions of interest and the selected resolution is initiated by an automated process.

4. The method claimed in claim 1, wherein capturing digital video includes real time digital video.

5. The method claimed in claim 1, wherein steps (d) through (h) are deferred until a transmission medium is available.

6. The method claimed in claim 1, wherein the selected resolutions greater than the resolution of the video sequence of the lower resolution representation correspond to a factor of two.

7. The method claimed in claim 1, wherein the video sequence of the lower resolution representation is compressed with an MPEG family of standards.

8. The method claimed in claim 1, wherein the video sequence of the lower resolution representation is compressed with a Motion JPEG 2000 standard.

9. The method claimed in claim 1, wherein the video sequence of the lower resolution representation is compressed with a video coding technique.

10. A method of transmitting selected regions of interest of digital video data and/or still imagery data at selected resolutions, comprising the steps of:

a) capturing digital video;

b) compressing the digital video into a sequence of individual high resolution JPEG 2000 frames and simultaneously extracting from the compressed high resolution JPEG 2000 frames a lower resolution representation of each of the individual high resolution JPEG 2000 frames;

c) storing the individual high resolution JPEG 2000 frames in a storage device;

d) creating a video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames;

e) transmitting the video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames to a user;

f) creating one or more JPEG 2000 high resolution still frames by extracting one or more regions of interest at selected resolutions from the stored individual high resolution JPEG 2000 frames;

g) creating one or more video sequences of selected regions of interest at selected resolutions greater than the resolution of the video sequence of the lower resolution representation;

h) transmitting one or more video sequences of selected regions of interest at selected resolutions and/or one or more of the high resolution JPEG 2000 still frames created in step (f); and

i) repeating steps (f) through (h) at incrementally increased resolutions until a desired resolution of the selected region of interest is reached according to a viewing objective.

11. The method claimed in claim 10, wherein the user selects the regions of interest and the selected resolution.

12. The method claimed in claim 10, wherein selection of the regions of interest and the selected resolution is initiated by an automated process.

14. The method claimed in claim 10, wherein the video sequence of the lower resolution representation is compressed with a Motion JPEG 2000 standard.

15. The method claimed in claim 10, wherein the video sequence of the lower resolution representation is compressed with a video coding technique.

16. The method claimed in claim 10, wherein the extracted regions of interest at selected resolution are in JPEG 2000 format.

17. The method claimed in claim 16, wherein the extracted regions of interest at selected resolution are transmitted using JPIP protocol.

18. The method claimed in claim 10, wherein capturing digital video includes real time digital video.

19. The method claimed in claim 10, wherein steps (d) through (i) are deferred until a transmission medium is available.

20. The method claimed in claim 10, wherein the selected resolutions greater than the resolution of the video sequence of the lower resolution representation correspond to a factor of two.

21. A method of transmitting selected regions of interest of digital video data at selected resolutions, comprising the steps of:

a) capturing digital video;

b) compressing the digital video into a sequence of individual high resolution JPEG 2000 frames and simultaneously extracting from the compressed high resolution JPEG 2000 frames a lower resolution representation of each of the individual high resolution JPEG 2000 frames;

d) searching for an alert condition within the sequence of individual high resolution JPEG 2000 frames;

e) repeating steps (a) through (d) until capturing of the digital video ends;

f) creating a video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames upon finding the alert condition;

g) transmitting the video sequence of the lower resolution representation of each of the stored individual high resolution JPEG 2000 frames to a user upon finding the alert condition;

h) creating one or more video sequences of selected regions of interest at selected resolutions greater than the resolution of the video sequence of the lower resolution representation upon finding the alert condition;
