Problems solved by technology

However, in some cases, it is necessary to query real-time video data before a specific time, such as data before 6 months. If all data are deleted, relevant information will not be obtained, and the requirements for retrospective queries cannot be met.

Embodiment 1

[0043] In this embodiment, the resolution of the second compressed video is 1 / N of the resolution of the real-time video compressed in the second compression process 2 , N represents the second compression ratio, and W 0 and H 0 relevant. In one example, N is ⌊W 0 / W P ⌋ and ⌊H 0 / H P The smaller of ⌋, W 0 *H 0 is the resolution of the real-time video compressed in the second compression process, W P *H P is the default minimum resolution. That is, the resolution W1*H1 of the second compressed video is different from the resolution W of the real-time video compressed in the second compression process 0 *H 0 The relationship is: W1=W 0 / N, H1=H 0 / N. In a specific example, the preset minimum resolution W P *H P It can be 320*240, that is, N is ⌊W 0 / 320 ⌋ and ⌊H 0 / 240⌋, so that the minimum resolution of the compressed video in the second compression process is 320*240. In an example, when the resolution of the real-time video is 1920*1080, N is the smaller 4...

Embodiment 2

[0046] In this embodiment, the resolution of the second compressed video is 1 / N of the resolution of the real-time video compressed in the second compression process 2 , N represents the second compression ratio, and W 0 and H 0 relevant. In one example, N is W 0 / W P and H 0 / H P The smaller of, W 0 *H 0 is the resolution of the real-time video compressed in the second compression process, W P *H P is the default minimum resolution. That is, the resolution W1*H1 of the second compressed video is different from the resolution W of the real-time video compressed in the second compression process 0 *H 0 The relationship is: W1= W 0 / N, H1=H 0 / N. In a specific example, the preset minimum resolution W P *H P It can be 320*240, that is, N is W 0 / 320 and H 0 / 240, so that the minimum resolution of the compressed video in the second compression process is 320*240.

[0047] In this embodiment, if N obtained based on the resolution of the compressed real-time video...

Abstract

The invention provides a data processing method. The data processing method comprises the steps of storing video data according to a preset storage mode; carrying out first compression and second compression on the videos of which the compression marks in the stored video represent that the videos are not compressed and the video access time exceeds a preset deletion period to respectively form afirst compressed video and a second compressed video, the resolution of the first compressed video being equal to the resolution of the real-time video, the number of frames being lower than the number of frames of the real-time video, the resolution of the second compressed video being lower than the resolution of the real-time video, and the number of frames being equal to the number of frames of the real-time video; appending the first compressed video to the second compressed video in the form of a binary stream to form a combined compressed video, and setting a compression flag of the video to characterize a compressed flag value. According to the invention, long-time-period video data can be stored as much as possible and the requirement of backtracking query can be met.

Description

technical field [0001] The invention relates to a data processing method and system, in particular to a video data processing method and system. Background technique [0002] With the advent of the Internet age, video data has become an important means of obtaining information in human life. However, the video data is very large, especially the video data stored in real time is particularly large, such as surveillance video, which takes up a large amount of memory space, and a large amount of video data is useless. Therefore, some video data must be deleted every once in a while (for example, 3-6 months), otherwise the memory space will not fit. However, in some cases, it is necessary to query real-time video data before a specific time, for example, if the data before 6 months is deleted, relevant information will not be obtained, and the requirements for retrospective query cannot be met. [0003] Therefore, there is an urgent need for a data processing method and system...
