Video recording intelligent playback method and device based on mobile information

Abstract

The invention relates to data application technology in the field of video monitoring, and discloses a video recording intelligent playback method and a device thereof based on mobile information. The method includes the following steps: searching for all motion detection additional information in the hard disk that meets the playback request time period, and storing the motion detection additional information as motion information in the mobile information linked list in chronological order; obtaining the current playback status and Playback time point, search the latest movement information under the current playback mode and current playback time point from the movement information linked list; match the found recent movement information with the current playback time point; control the playback speed according to the matching result to realize intelligent Automatic control of playback speed. Repeating the above steps can realize real-time, automatic and continuous control of playback speed, so as to realize automatic adjustment to normal playback speed when there is movement information, fast playback when there is no movement information, and shorten the playback time of video recording.

Description

technical field [0001] The invention relates to the data application technology in the field of video monitoring, in particular to the intelligent playback technology of video recording based on mobile information. Background technique [0002] At present, in the field of video surveillance, more attention is paid to valuable dynamic pictures when playing back video recording files, but in fact video recordings usually contain a large number of static pictures without motion information. Therefore, when playing back video recordings, users often search for dynamic images by dragging or adjusting the playback speed. These methods are often easy to miss the dynamic pictures that need to be paid attention to, and the manual operation has defects such as low efficiency, low precision, and inconvenience. [0003] In the "Method, System and Device for Adjusting the Playing Speed ​​of Video Recording", a speed level is proposed by analyzing the speed level encoded in the key frame...

AI Technical Summary

Problems solved by technology

[0005] (1) The media server selectively obtains video data from the storage device according to the playback speed, which may easily cause the loss of the playback screen

[0006] (2) If the video recording file is composed of many dynamic pictures with small time intervals within a certain period of time, the speed level is continuously adjusted by analyzing the speed level encoded in the key frame video data, which may cause unsmooth playback
