Large format video archival, storage, and retrieval system and method
View Patent ↗A method for storing a video on a storage device includes formatting each image in a plurality of images into a plurality of tiles, the plurality of images being captured as a temporal sequence of images at successive points in time; and generating a plurality of video segments from the temporal sequence of images by: selecting a tile from each image in the sequence of images to obtain a sequence of tiles to generate a video segment; selecting another tile from each image in the sequence of images to obtain another sequence of tiles to generate another video segment; and repeating the selecting a tile from each image in the sequence of images to obtain a plurality of sequences of tiles to generate the plurality of video segments. The method further includes storing the obtained plurality of video segments in a file on the storage device.
1. A method, implemented by a computer system, for storing a video on a storage device, the method comprising:
formatting, using the computer system, a first image into a first tile and a second tile;
formatting, using the computer system, a second image into a first tile and a second tile, the first image and the second image being captured as a temporal sequence at successive points in time;
generating a first video segment by selecting the first tile of the first image and the first tile of the second image, in sequence;
generating a second video segment by selecting the second tile of the first image and the second tile of the second image, in sequence; and
storing, by the computer system, the first video segment and the second video segment in a file on the storage device.
2. The method of claim 1 , wherein the first tile and the second tile of the first image have overlapping portions and the first tile and the second tile of the second image have overlapping portions, the overlapping portions overlap by an adjustable amount and include substantially identical pixel data.
3. The method of claim 2 , wherein a size of the overlapping portions of the first tile and the second tile of first image is substantially equal to a size of a display area of a display device, and a size of the overlapping portions of the first tile and the second tile of the second image is substantially equal to the size of the display area of the display device.
4. The method of claim 1 , further comprising formatting a reduced resolution dataset for the first image and the second image.
5. The method of claim 4 , wherein the formatting a reduced resolution dataset for the first image and the second image comprises formatting a reduced resolution dataset for the first image and the second image such that each reduced resolution dataset comprises one or more tiles.
6. The method of claim 5 , wherein the reduced resolution dataset of the first image has successively lower image resolution and fewer pixels than a previous reduced resolution dataset and each reduced resolution dataset captures substantially an entire image area, and wherein the reduced resolution dataset of the second image has successively lower image resolution and fewer pixels than a previous reduced resolution dataset and each reduced resolution dataset captures substantially an entire image area.
7. The method of claim 5 , further comprising formatting the reduced resolution dataset of the first image to include overlapping tiles and formatting the reduced resolution dataset of the second image to include overlapping tiles.
8. The method of claim 1 , wherein the storing comprises storing sequentially the first video segment and the second video segment.
9. The method of claim 1 , wherein the storing comprises storing in an interleaved format the first video segment and the second video segment.
10. The method of claim 1 , further comprising accessing the first video segment or the second video segment through a single seek and a single read operation of the storage device.
11. The method of claim 1 , wherein the storing comprises storing the first tile and the second tile of the first image and storing the first tile and the second tile of the second image at a disk block boundary of the storage device so as to optimize access to the storage device.
12. The method of claim 1 , wherein the storing comprises storing the first video segment and the second video segment as equal length records on the storage device.
13. The method of claim 12 , wherein the storing comprises padding the first video segment or padding the second video segment, or both with additional data so as to obtain equal length records.
14. The method of claim 1 , further comprising formatting the storage device to store the first video segment and the second video segment on the storage device as a plurality of equal length records for optimized retrieval from the storage device.
15. The method of claim 1 , wherein the storing comprises storing the first video segment and the second video segment as a plurality of variable length records on the storage device.
16. The method of claim 1 , further comprising formatting the storage device to store the first video segment and the second video segment as a plurality of variable length records for optimized retrieval.
17. The method of claim 1 , further comprising formatting the storage device to include a block size, wherein a size of the first video segment and a size of the second video segment is an integer multiple of the block size.
18. The method of claim 1 , further comprising encoding the first video segment or encoding the second video segment, or both with motion compensation to compress a size of the first video segment or to compress a size of the second video segment, or both.
