Abstract

A method of video operations includes generating derivative byproducts related to encoded video captured of a scene, initializing a first operation based on the encoded video, and initializing a second operation different from the first operation based on the derivative byproducts.

Claims

1. A computerized method of facilitating video operations comprising:

producing, by an encoder of a computer system, compressed video data from source video date output by a video capture device, the source video data capturing a scene;

identifying, by the encoder as part of the producing, a plurality of macroblocks;

outputting, by the encoder as an initial byproduct of the producing, data characterizing motion corresponding to at least one macroblock of the plurality of macroblocks;

generating, by the computer system, a derivative byproduct based on the initial byproduct, the derivative byproduct quantifying motion corresponding to the at least one macroblocks, the derivative byproduct further including at least one of a time stamp, an alert requirement, a time stamp of when movement occurred, the amount of movement needed to trigger an alarm, and the amount of movement needed to turn the alarm off;

initiating, by the computer system, a supplemental operation, supplemental to a primary operation, based on the derivative byproduct;

generating a motion map using results of the supplemental operation, the motion map being associated with a video frame and providing a byte-value representation of motion of a corresponding macroblock; and

synchronizing the motion map with the video frame using an extension.

2. The computerized method of claim 1, wherein the supplemental operation includes any of highlighting a specific portion of the scene as displayed, setting an alert or changing a position of the video capture device.

3. The computerized method of claim 1, wherein the supplemental operation includes generating an indication that a state of motion detection capability has changed and creating a time stamp for the generated indication.

4. The computerized method of claim 3, wherein the indication that a state of the motion detection capability has changed includes that the state of the motion detection capability has changed to an OFF state.

5. The computerized method of claim 3, wherein the indication that a state of the motion detection capability has changed includes that the state of the motion detection capability has changed to an ON state.

6. The computerized method of claim 1, wherein the primary operation includes any of displaying, streaming or storing the encoded video.

7. The computerized method of claim 1, further comprising transmitting the derivative byproduct and compressed video data to a decoder of the computer system.

8. The computerized method of claim 1, wherein the motion map is included in a header attached to the video frame.

9. The computerized method of claim 8, wherein the header further includes at least one of an energy vector, a current motion state, an upper threshold, a lower threshold, a vector length, a number of macroblocks in motion in a frame, a number of macroblocks in motion in a mask, a height of the motion map in macroblocks, or a width of the motion map in macroblocks.

10. The computerized method of claim 1, wherein the motion map is synchronized with the video frame only when the motion map is enabled.

11. A non-transitory computer-readable medium having instructions stored thereon for facilitating video operation, wherein the instructions, when executed by a processing system, direct the processing system to:

produce compressed video data from source video data output by a video capture device, the source video data capturing a scene;

identify, as part of producing the compressed video data, a plurality of macroblocks;

output, as an initial byproduct of producing the compressed video data, data characterizing motion corresponding to at least one macro block of the plurality of macroblocks;

generate a derivative byproduct based on the initial byproduct, the derivative byproduct quantifying motion corresponding to the at least one macroblock, the derivative byproduct further including at least one of a time stamp, an alert requirement, a time stamp of when movement occurred, the amount of movement needed to trigger an alarm, and the amount of movement needed to turn the alarm off;

initiate a supplemental operation, supplemental to a primary operation, based on the derivative byproduct;

generate a motion map using results of the supplemental operation, the motion map being associated with a video frame and providing a byte-value representation of motion of a corresponding macroblock; and

synchronize the motion map with the video frame using an extension.

12. The non-transitory computer-readable medium of claim 11, wherein the supplemental operation includes any of highlighting a specific portion of the scene as displayed, setting an alert of changing a position of the video capture device.

13. The non-transitory computer-readable medium of claim 11, wherein the supplemental operation includes generating an indication that a state of motion detection capability has changed and creating a time stamp for the generated indication.

14. The non-transitory computer-readable medium of claim 13, wherein the indication that a state of the motion detection capability has changed includes that the state of the motion detection capability has changed to OFF.

15. The non-transitory computer-readable medium of claim 13, wherein the indication that a state of the motion detection capability has changed includes that the state of the motion detection capability has changed to ON.

16. The non-transitory computer-readable medium of claim 11, wherein the primary operation includes any of displaying, streaming or storing the encoded video.

17. The non-transitory computer-readable medium of claim 11, wherein the instructions further direct the processing system to transmit the derivative byproduct and compressed video data to a decoder.

18. The non-transitory computer-readable medium of claim 11, wherein the motion map is included in a header attached to the video frame.

19. The non-transitory computer-readable medium of claim 18, wherein the header further includes at least one of an energy vector, a current motion state, an upper threshold, a lower threshold, a vector length, a number of macroblocks in motion in a frame, a number of macroblocks in motion in a mask, a height of the motion map in macroblocks, or a width of the motion map in macroblocks.

20. The non-transitory computer-readable medium of claim 11, wherein the motion map is synchronized with the video frame only when the motion map is enabled.
