System and method for improved video operations
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.
1. A computerized method of generating video byproducts comprising:
defining a plurality of macroblocks, wherein the plurality of macroblocks overlay a scene to be reported;
recording a plurality of images of the scene;
comparing motion of an object between a plurality of images by comparing a change in position of a macroblock that overlays the object;
recording the motion as a byproduct by recording a number of pixels of change in position of the macroblock;
measuring a magnitude of change in position of the macroblock; and
implementing a motion map having a plurality of motion map entries synchronized with the plurality of macroblocks of a corresponding video frame.
2. The computerized method of claim 1 , wherein each of the plurality of motion map entries is a byte-value giving the current level of motion in the corresponding synchronized macroblock.
3. The computerized method of claim 1 , wherein the motion map is implemented at a fixed resolution.
4. The computerized method of claim 3 , wherein the fixed resolution matches VSIP mask string convention.
5. The computerized method of claim 1 , wherein implementing the motion map is performed on a single input.
6. The computerized method of claim 5 , wherein implementing the motion map is on a second input stops the motion map on a first input.
7. The computerized method of claim 1 , wherein motion map includes a data buffer attached to the frame of the video and containing motion map data.
8. The computerized method of claim 7 , wherein the motion map data has a structure wherein the width and height of the map is given in number of macroblocks.
9. The computerized method of claim 7 , wherein the data buffer includes at least one of the energy vector, current motion state, upper threshold, lower threshold, vector length and number of macroblocks in motion.
10. The computerized method of claim 9 , wherein the energy vector is added to send the motion map through a RTP extension which only supports one extension at a time.
11. A non-transitory computer-readable medium having an instruction stored thereon for generating video byproducts, wherein the instructions, when executed by the processing system, direct the processing system to:
define a plurality of macroblocks, wherein the plurality of macroblocks overlay a scene to be reported;
record a plurality of images of the scene;
compare motion of an object between a plurality of images by comparing a change in position of a macroblock that overlays the object;
record the motion as a byproduct by recording a number of pixels of change in position of the macroblock;
measure a magnitude of change in position of the macroblock; and
implement a motion map having a plurality of motion map entries synchronized with the plurality of macroblocks of a corresponding video frame.
12. The non-transitory computer-readable medium of claim 11 , wherein each of the plurality of motion map entries is a byte-value giving the current level of motion in the corresponding synchronized macroblock.
13. The non-transitory computer-readable medium of claim 11 , wherein the motion map is implemented at a fixed resolution.
14. The non-transitory computer-readable medium of claim 13 , wherein the fixed resolution matches VSIP mask string convention.
15. The non-transitory computer-readable medium of claim 11 , wherein implementing the motion map is performed on a single input.
16. The non-transitory computer-readable medium of claim 15 , wherein implementing the motion map is on a second input stops the motion map on a first input.
17. The non-transitory computer-readable medium of claim 11 , wherein motion map includes a data buffer attached to the frame of the video and containing motion map data.
18. The non-transitory computer-readable medium of claim 17 , wherein the motion map data has a structure wherein the width and height of the map is given in number of macroblocks.
19. The non-transitory computer-readable medium of claim 17 , wherein the data buffer includes at least one of the energy vector, current motion state, upper threshold, lower threshold, vector length and number of macroblocks in motion.
20. The non-transitory computer-readable medium of claim 19 , wherein the energy vector is added to send the motion map through a RTP extension which only supports one extension at a time.
