Embodiment 1

[0073] Embodiment 1, the video management server selects the path with the smallest routing metric value.

[0074] The front-end device reports the calculated route metric values ​​to MS1 and MS2 to the video management server;

[0075] MS1 and MS2 calculate the route metric value to the client and report it to the video management server;

[0076] MS1 calculates the route metric value from MS1 to MS2, and reports it to the video management server;

[0077] The video management server calculates and compares the routing metric values ​​of each path, and selects the path with the smallest routing metric value as the path for the client to send video streaming media.

Embodiment 2

[0078] Embodiment 2: The path with the smallest routing metric value is selected by the front-end device.

[0079] The front-end device calculates the routing metric values ​​from the front-end device to MS1 and to MS2;

[0080] Obtain the route metric value from MS1 to the client, the route metric value from MS1 to MS2, and the route metric value from MS2 to the client from MS1 and MS2;

[0081] Calculate and compare the routing metric values ​​of each path, and select the path with the smallest routing metric value as the path for the client to send video streaming media.

[0082]It is easy to understand that whether it is a front-end device or a video management server, it is easy to obtain the route metrics needed for calculation from other devices. For example, the front-end device can obtain the route metrics from MS1 to MS2 from MS1, and can also transfer MS1 to MS2 in MS1. After the route metric value to MS2 is reported to the video management server, the route metric...

Abstract

The invention discloses a video monitoring system and a method for the video monitoring system to select a media stream sending path. The method comprises the steps that firstly, front-end equipment and a client device determine a media server MS1 and a media server MS2 respectively, wherein the MS1 and the MS2 are closest to the routing metric value of the front-end equipment and the routing metric value of the client device respectively; secondly, the routing metric value from the front-end equipment to the MS1, the routing metric value from the front-end equipment to the MS2, the routing metric value from the MS1 to the MS2, the routing metric value from the MS1 to the client and the routing metric value from the MS2 to the client device are calculated respectively, the front-end equipment or a video management server conducts comparison to obtain the path through which the routing metric value from the front-end equipment to the client device is minimum, and the front-end equipment sends the media streams to the client device along the path with the minimum routing metric value. By means of the method, the path with a minimum time delay is selected to conduct video playing, so that actual use experience of a user is promoted.

Description

technical field [0001] The invention belongs to the technical field of video monitoring, and in particular relates to a video monitoring system and a method for selecting a sending path of a media stream. Background technique [0002] Video surveillance is an important part of the security system. Video surveillance is widely used in many occasions because of its intuition, accuracy, timeliness and rich information content. In recent years, with the rapid development of computer, network, image processing and transmission technology, the popularization trend of video surveillance has become more and more obvious. In particular, cross-regional departmental branches and globally distributed business groups have an increasing demand for remote Internet video surveillance, which has received special attention in the industry. However, since the Internet is an open network, the performance of network equipment on the network varies, the interconnection between various operators,...
