Abstract

To generate a compressed video having a reduced video file size, an original video having a plurality of images are captured. Each of the plurality of images are compared. If images of the plurality of images are determined to be redundant images, the images are deleted. The original video having the redundant images removed is saved to form the compressed video.

Claims (39)

1. A method of reducing a video file size, comprising:

receiving an original video having a plurality of images;

determining a first set of sequential images of the plurality of images having different views of a location;

determining a subsequent second set of sequential images of the plurality of images having the different views of the location;

comparing the first and second sets of sequential images;

deleting the second set of sequential images as redundant images when the comparison indicates that the second set of sequential images is substantially similar to the first set of sequential images;

saving the original video having the redundant images removed to form a compressed video, wherein the compressed video includes a number indicator to indicate quantity of the redundant images removed from the original image; and

recovering the redundant images deleted from the original video when playing the compressed video.

2. The method claim 1 , further comprising:

transmitting the compressed video to a mobile device through a network.

3. The method claim 1 , wherein the compressed video is a different file format than the original video.

4. The method claim 1 , wherein the compressed video is a same file format as the original video.

5. The method claim 1 , wherein the compressed video includes a timestamp to indicate where the redundant images are removed.

6. The method claim 1 , wherein the redundant images are images indicating no motion detected within a timeframe of the redundant images.

7. The method claim 1 , wherein the original video is a H264 video or a MPEG4 video.

8. A method of playing a compressed video, comprising:

a mobile device receiving the compressed video through a network, wherein the compressed video includes a number indicator to indicate quantity of the redundant images deleted from an original video, wherein the redundant images are a second set of sequential images having different views of a location subsequent to and substantially similar to a first set of sequential images having the different views of a location;

decompressing the compressed video file and recovering the redundant images deleted from the original video to include the redundant images to form a decompressed video; and

playing the decompressed video on the mobile device.

9. The method claim 8 , wherein the compressed video includes a timestamp to indicate where the redundant images are removed.

10. The method claim 9 , wherein decompressing the compressed video file to include redundant images deleted from an original video to form a decompressed video comprises:

determining where to insert the redundant images in the compressed video according to the timestamp;

determining the number of the redundant images to be inserted into the compressed video according to the number indicator; and

forming the decompressed video having the redundant images inserted into the compressed video where the timestamp has indicated.

11. The method claim 8 , wherein the compressed video is a different file format than the original video.

12. A method for transmitting a compressed video, comprising:

receiving a plurality of images of a pre-compressed video;

determining a first set of sequential images of the plurality of images having different views of a location;

determining a subsequent second set of sequential images of the plurality of images having the different views of the location;

transmitting a static image tag and deleting the second set of sequential images as redundant images when the comparison indicates that the second set of sequential images is substantially similar to the first set of sequential images, wherein the static image tag includes a number indicator to indicate quantity of the redundant images removed from the original pre-compressed video;

comparing a motion value of the images and a predetermined value when the images second set of sequential images is not substantially similar to the first set of sequential images;

when the motion value is greater than the predetermined value, transmitting the second set of sequential images;

when the motion value is less than the predetermined value, transmitting a static image tag; and

recovering the redundant images deleted from the original pre-compressed video when playing the compressed video.

13. The method in claim 12 , wherein the pre-compressed video is a H264 video or a MPEG4 video.

14. A method for receiving a compressed video, comprising:

receiving the compressed video, the compressed video having a plurality of images and a static image tag, wherein the static image tag includes a number indicator to indicate quantity of redundant images removed from an original video and the redundant images are a second set of sequential images from the original video having different views of a location subsequent to and substantially similar to a first set of sequential images from the original video having the different views of a location;

when an image of the plurality of images is detected, displaying the image; and

when the static image tag is detected, recovering the redundant images removed from the original video to include the redundant images when playing the compressed video.
