Embodiment 1

[0063] Embodiment 1 of the present invention provides a method for identifying video content, and the method describes the method for identifying video content from the side of a content distribution server. The step-by-step process can be as follows figure 1 shown, including:

[0064] Step 101, task generation.

[0065] In this step, the content distribution server may segment the video captured by the camera in real time, specifically, but not limited to, segment the video captured by the camera in real time according to a set duration. And each video segment obtained by segmentation can be packaged as a video task.

[0066] Step 102, task allocation.

[0067] In this step, for each video task, the content distribution server may assign the video task to a management node in the edge device, the edge device is pre-selected, and instruct the management node to assign the video task to at least one edge The device is configured to perform content identification on a video ...

Embodiment 2

[0082] Embodiment 2 of the present invention provides a method for identifying video content, and the method describes the method for identifying video content from the side of an edge device serving as a management node. The step-by-step process can be as follows image 3 shown, including:

[0083] Step 201, receiving a video task.

[0084] In this step, the edge device as the management node can receive the video task assigned by the content distribution server.

[0085] Step 202, task broadcasting.

[0086] In this step, the edge device serving as the management node may broadcast the task requirement corresponding to the video task to pre-selected edge devices, each edge device except itself.

[0087] Step 203, receiving an available resource prediction result.

[0088] In this step, the edge device as the management node can receive the available resource prediction result reported by the edge device, the available resource prediction result is predicted by the edge d...

Embodiment 3

[0099] Embodiment 3 of the present invention provides a method for identifying video content, and the method describes the method for identifying video content from the side of an edge device that is a non-management node. The step-by-step process can be as follows Figure 4 shown, including:

[0100] Step 301, receiving a broadcast.

[0101] In this step, the edge device as the non-management node may receive the task requirement corresponding to the video task broadcast by the edge device as the management node.

[0102] Step 302. Determine the forecast result of available resources.

[0103] In this step, the edge device as a non-management node may determine the available resource prediction result and report it to the edge device as a management node. The available resource prediction result is predicted, and the remaining available resource information after removing the resource loss corresponding to the task requirement among the currently available resources instru...

Abstract

The invention relates to the technical field of video processing, in particular to a video content identification method, equipment, a medium and a system. Aiming at the problem of high resource occupancy rate or low identification accuracy of a video identification end during automatic real-time identification of video contents in the existing security monitoring system, the embodiment of the invention provides a scheme for performing real-time video processing on an edge side and cooperatively finishing real-time video identification based on redundant resources and computing power of edge equipment. According to the scheme, the existing edge equipments (such as a set top box and an intelligent home gateway) are utilized to form an edge computing network, and real-time processing of videos is completed on the edge side through a series of methods such as allocation and scheduling of video tasks and prediction of available resources.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a method, device, medium and system for identifying video content. Background technique [0002] In current security surveillance systems, camera equipment is used to capture video. After the video is collected, the existing technology generally adopts the following schemes for video content identification, and realizes security monitoring by identifying specified events in the video, such as falling objects, illegal parking, theft, etc.: [0003] 1. Manual video recognition: Through the real-time observation of video by monitoring personnel, the recognition of events in the video is completed. [0004] 2. Playback recognition after recording: record video in real time to storage device for subsequent recognition. [0005] 3. Cloud or server-side recognition: Real-time transmission of video to the cloud or server-side for recognition. [0006] 4. After the vid...
