Problems solved by technology

[0006] 1. After the tandem platform is connected to multiple lower-level platforms, it manages a large number of video channels, and pre-allocated resources cause a heavy load on the tandem platform.
[0007] 2. The number of video channels supported by a single server is limited (no more than 500 channels). If resources are allocated in advance, multiple servers are required to support and increase costs
[0008] 3. Static configuration requires the administrator to set parameters for each channel of video, which puts a lot of pressure on the administrator

Embodiment Construction

[0036] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0037] Fig. 3 is a flowchart of a video forwarding control method of a multi-level architecture video surveillance system. In Fig. 3, step 101: the media processing unit VTDU starts, creates a port to listen to the ListenSocket thread, and waits for the central management service unit CMS to connect;

[0038] Step 102: The central management service unit CMS connects to the media processing unit VTDU, and sends a registration request message to the media processing unit VTDU, with system-related parameters, mainly the maximum load of this VTDU (specified by the administrator when adding a VTDU server). After that, the CMS registers.

[0039] Step 103: After successful registration, the central management service unit...

Abstract

The invention discloses a method for controlling the video forwarding in a multistage architecture video monitoring system and belongs to the technical field of the video monitoring. The technical scheme is as follows: the control over a video transfer and dispatch unit VTDU imposed by the central manager server CMS is enhanced; when the VTDU starts and does not establish the video forwarding process and a client successfully logs on the CMS, a video request is firstly sent to the CMS, and the CMS forwards the video request to the VTDU; after the video request is received, the VTDU queries whether the video exists or not, and informs a forwarding process that the video should be sent to a client side sending a request; when the video is found not existing, a corresponding forwarding process should be established so as to realize the dynamic establishment of the forwarding process; and when the output of the forwarding process is idle, the forwarding process automatically ends. The invention realizes the dynamic establishment and the demand assignment of the video forwarding process, solves the problem that the system volume is limited, and saves the hardware cost.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a video forwarding control method of a video monitoring system with a multi-level structure. Background technique [0002] The multi-level architecture video surveillance system is divided into access platform and tandem platform. Figure 1 is an overall architecture diagram of a multi-level architecture video surveillance system. In Figure 1, the modules included in each platform are: CMS (CentralManager Server), NRU (Network Record Unit) and VTDU (Video Transfer and Dispatch Unit). CMS is the central management service unit of the network video monitoring center platform system; NRU is the network recording server of the network video monitoring center platform system; VTDU is the media processing unit of the network video monitoring center platform system, responsible for the forwarding management of video streams. A solid line without an arrow indicates ...
