Method and device for on-demand playback of video surveillance video

Abstract

The invention provides a method and device for on-demand playback of video surveillance video. The method includes: Step 1, storing the received video stream in real time, forming a plurality of storage files whose file names include the video generation time, and the duration of the video stored in each of the storage files is less than or equal to the first predetermined duration; Step 2, According to the starting time point of the playback video requested in the playback request, match the file name of the stored file, find the stored video containing the corresponding video of the starting time point in the stored video as the target file; step 3, Add index information to the target file; step 4, perform video playback from the starting time point according to the index information. The invention can quickly allow users to watch playback videos without seriously wasting system resources.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a method and device for on-demand playback of video monitoring recordings. Background technique [0002] The video surveillance system is an important part of the security technology system. With the rapid development of science and technology, the maturity of digital video technology, and the maturity and commercialization of CCD (Charge Coupled Device) camera technology, the digital video surveillance system has It has become the mainstream technology used in current video surveillance. In the digital video monitoring system, the image content of the monitored place can be transmitted to the monitoring center, so that the situation of the monitored place can be seen at a glance. Another feature of the digital video surveillance system is that it can record all or part of the images and sounds of the monitored place, which provides convenient conditions and important basis for t...

Problems solved by technology

[0005] 1) If the method of adding an index as soon as the video stream is received and then storing the video can be used to quickly respond to the user watching the image during playback, but because of the small playback requirements, this method not only puts higher demands on the configuration of the storage server Requires and is a serious waste of system resources;

[0006] 2) If the method of indexing all files when on-demand is adopted, it will have an impact on the playback time, resulting in the disadvantage that the user waits too long

[0008] However, at present, the encoder index formats of various manufacturers do not support or the index format is not uniform. When it is necessary to support different manufacturers, there will be different index organization methods due to different manufacturers, resulting in the inability of a unified interface for the project; When the encoder index format manufacturer, the playback of the video at the specified time point cannot be realized
