Problems solved by technology

[0005] It is not difficult to see that in the existing solution, the establishment and disassembly of DC and EC business sessions, auditing, etc. are all controlled by the control server, which will cause excessive load on the control server and seriously affect the efficiency and Control the performance of the server, and in severe cases, it will directly lead to the failure of the user's on-demand

Embodiment Construction

[0032] In order to reduce the load on the control server and reduce the burden on the control server, in the technical solution of the present invention, the audit work of the on-demand authority is transferred to the on-demand EC for processing, and the transmission work of the on-demand service is further transferred to both sides of the on-demand service communication DC and EC processing, so that the management work of the on-demand service is distributed to each role of the whole system, which realizes the load reduction of the control server and improves the robustness of the whole system.

[0033] see figure 2 , figure 2 It is the general flowchart of the method of the present invention. In step 201, when a user logs in to the DC, the control server sends to the DC a list of video-on-demand cameras within the scope of the user's rights, and the camera list includes camera information and corresponding video-on-demand rights. In step 202, in response to the request o...

Abstract

The invention discloses a method, a decoder (DC) and an encoder (EC) for video monitoring. In the technical scheme provided by the invention, examination and verification on a request authority is processed by the requested EC, and transmission of a request service is processed by the DC and the EC which serve as two communication parties of the request service, so that the request service processed by a control server is distributed to equipment in a system for processing; therefore, the load of the control server is reduced, the burden of the control server is relieved, and the robustness of the whole system is enhanced.

Description

technical field [0001] The invention relates to monitoring technology, especially to a video monitoring method, a decoder and an encoder for video monitoring. Background technique [0002] see figure 1 , figure 1 It is a structural diagram of a video surveillance system in the prior art, including a camera, an encoder (EC, Encoder), a decoder (DC, Decode) and a control server. The camera is used for real-time monitoring, and the EC is used to convert the analog audio and video signals obtained by the camera monitoring into digital signals and process them with real-time audio and video compression algorithms, then transmit the data to the network for real-time viewing or storage. The processing flow of the DC is opposite to that of the EC. The DC obtains the video stream from the network side, decodes the video stream, and presents the restored audio and video signals to the user. [0003] In the process of viewing the camera surveillance video by the user, the control se...
