Embodiment 1

[0037] Such as image 3 As shown, the file storage coverage method based on moving vectors includes the following steps:

[0038] (1) An index block used to store the judging criteria is established in the storage medium, and the index block contains the motion vector threshold set by the user. Users can dynamically modify the storage content in the storage medium.

[0039] (2) In each file storage block of the storage medium, set up a header information used to store the statistical value of the motion vector in the file; when storing the video file, count the number of motion vectors at the same time, and count the motion vectors counted into the current file storage in the header information of the block.

[0040] Each video file storage block has a header information, which is used to count the statistics of the number of motion vectors in this video block:

[0041] a. The statistics of the number of motion vectors in the video file are recorded in the header informatio...

Embodiment 2

[0050] On the basis of Embodiment 1, the index block in step (1) also includes the time period priority value set by the user; the header information of each file storage block in step (2) also includes storing the current movement vector The time distribution table of the statistical value of the number of moving vectors, and the moving vector statistics are included in the corresponding time period of the time distribution table according to the occurrence time. Taking the 24-hour distribution table as an example, the data stored in the table is the number of moving vectors in the current hour. Statistics.

[0051] Such as image 3 As shown, the file storage coverage method based on moving vectors, the specific steps include:

[0052] (1) Create an index block used to store the evaluation criteria in the storage medium, see figure 1 , the index block contains a, the motion vector threshold set by the user, and b, the priority value of the time period set by the user. User...

Abstract

The invention relates to a motion vector based file storage overlay method, comprising the following steps: setting index blocks in storage media, setting header information for each video file storage block and deciding whether to delete the video file storage blocks by comparing the total statistics of the amount of the motion vectors of the header information in the video file storage blocks and the thresholds of the motion vectors in the index blocks, wherein the thresholds are set by users. The invention further sets time period preferred values in the index blocks. If the storage media are not enough to store the current video files, the time period preferred values and the thresholds of the motion vectors, which are set by the users, are read, according to time sequence, the statistics of the amount of the motion vectors in the time period in the header information of each file storage block are compared with the thresholds of the motion vectors to decide whether to delete the video file storage blocks. Compared with the prior art, the method has intelligence and can enable the useful history files to be stored for a long time under the condition of full storage media.

Description

technical field [0001] The invention relates to a file storage overlay method, in particular to a method for realizing video file storage overlay, which is suitable for digital monitoring and video file overlay of video storage devices. Background technique [0002] In businesses that involve viewing historical video recordings, frequently encountered problems are: [0003] (1) The video file is full of the entire disk, and what strategy is adopted to clean up the old video to ensure the smooth progress of the new video; [0004] (2) How to delete old videos and ensure that old and possibly useful videos are not deleted as much as possible; [0005] (3) How to judge whether the video is useful, and what is the basis for judging; [0006] (4) How to avoid the deviation of the set standard without affecting the existing potentially useful video files as much as possible. [0007] Most of the existing video deletion technologies adopt the method of overwriting in chronologic...
