Universal play system and method for surveillance tape files

Abstract

The invention provides a universal play system and method for surveillance tape files. The method comprises the following steps that: video decoding container devices and image processing container devices provided by different manufacturers are encapsulated into corresponding manufacturer decoding sub-devices and image processing sub-devices; a user inputs the surveillance tape files; a surveillance manufacturer analyzing device analyzes the surveillance tape files according to file header information and file suffix to analyze the manufacturer source; then the video decoding container device decodes the surveillance tape files; the image processing container device carries out image sharpening on the images in a decoded image cache device; and a display device displays and outputs the images in the decoded image cache device. The surveillance tape files from different manufacturers can be played by the system. In addition, the universal play system and the universal play method capable of sharpening, clearly marking and accurately locating images in the decoding process are provided, so that the efficiency of public security departments and guards in finding and obtaining evidences from surveillance videos is improved.

Description

technical field [0001] The invention belongs to the playing technology of video files, and in particular relates to a general playing system and method for monitoring video files. Background technique [0002] At present, commonly used video playback files in the domestic market include Baofeng Video, QQ Video, qvod, PPS, KMPlayer, VLC, etc. These players are mainly developed for playing news and entertainment media, and often can only decode standard video formats such as MPEG-1, MPEG-2, MPEG-4, DivX, and H.264. When decoding, the video format is usually determined according to the video file header and suffix name, and the corresponding decoder is matched for decoding. Compared with news and entertainment media, surveillance video has different characteristics. First of all, surveillance video is often non-standard and must be decoded with a special decoder provided by the manufacturer; secondly, surveillance video files do not necessarily have a uniform and identifiable...

AI Technical Summary

Problems solved by technology

[0004] 1. Insufficient support for the video formats of surveillance manufacturers, and a large number of surveillance video files cannot be decoded normally

[0005] 2. Analyze the video encoding format by file header and suffix name, not applicable to surveillance video files

[0006] 3. In order to ensure fluency when playing news and entertainment videos, the picture quality is often reduced or image frames are discarded when the bandwidth or processing capacity is insufficient, which does not meet the needs of surveillance video viewing

[0007] 4. When the video is displayed, it only provides simple functions such as brightness adjustment, and does not clear the blurring caused by poor light, rain and fog in the surveillance video

[0008] 5. The hierarchical description information of the video content recorded by the intelligent monitoring equipment cannot be presented when the video is played

[0010] The difference in actual time leads to inaccurate overlay time, which brings inconvenience to video viewing
