Problems solved by technology

[0004] The current regular playback mode supports multi-channel playback, such as regular playback of 4-channel video files at the same time, but because the intelligent event information in the video files of multiple channels corresponds to different time periods or even overlaps, the current smart playback mode only supports single-channel playback

Embodiment Construction

[0093] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0094] figure 1 It is a schematic diagram of the implementation environment provided by some embodiments of the present invention. Such as figure 1 As shown, the implementation environment includes a video capture device 110 , a video storage and playback device 120 and a communication network 130 .

[0095] The video capture device 110 is used to capture and encode compressed video signals, and transmit the encoded and compressed video signals to the video storage and playback device 120 through the communication network 130 . Optionally, the video capture device 110 is also used to collect and compress audio signals, and transmit the compressed audio signals to the video storage and playback device 120 through the communication net...

Abstract

The invention discloses a video file playback method and device, belonging to the field of video surveillance. The video file playback method comprises the following steps: confirming the playback time point corresponding to an intelligent playback mode; obtaining the video files of N channels corresponding to the intelligent playback mode; retrieving at least one target video fragment from the video files of the N channels according to the order of the video time using the playback time point as the retrieving starting point, wherein the target video fragment is a video fragment which is identified with an intelligent event; intercepting the target video fragments from the video file of the corresponding channel; and replaying each target video fragment in the corresponding playback areaaccording to the belonging channel in the playback interface. The invention solves the problem in related technologies that the intelligent playback mode only supports single-path playback because thetime segments separately corresponding to the intelligent event information in the video files of a plurality of channels are different or even intersecting, therefore, the effect of supporting multi-channel intelligent playback is achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of video monitoring, and in particular to a method and device for playing back video files. Background technique [0002] The monitoring system generally includes: multiple network cameras (IP Camera, IPC) and network video recorders (Network Video Recorder, NVR). Each video file captured by the IPC corresponds to a video channel, and a video channel can be called a video. NVR has the ability to store and playback video files. [0003] There are two modes for playing back video files: normal playback mode and smart playback mode. In the regular playback mode, the video files are played back sequentially according to the recording time from early to late; in the smart playback mode, only the video clips marked with intelligent event information in the video file are played back, and the intelligent event information is provided by the IPC. The information identified when events such as moving o...
