Embodiment 1

[0041] figure 1 It is a flow chart of a video surveillance method provided by Embodiment 1 of the present invention. As shown in the figure, the method includes:

[0042] Step 101, the central management server (Center Manager Server, referred to as: CMS) in the video monitoring platform receives a video browsing request from a client unit (Client Unit, referred to as: CU), and the video browsing request carries a transcoding identification parameter . The transcoding identification parameter refers to the parameters of the code stream that can be decoded and played by the client unit, such as encoding format, resolution, frame rate, bit rate, encoding level and grade and other parameters. The transcoding identification parameter is a demand parameter proposed by the client unit for the code stream it needs to receive and play, and may include hardware parameters of the client unit, such as the size of the display screen, and may also include transmission parameters of the co...

Embodiment 2

[0065] image 3 It is a flow chart of a video surveillance method provided by Embodiment 2 of the present invention. As shown, with figure 1 Compared with the illustrated embodiment, step 105 is added in this embodiment. That is, in step 102, when the CMS in the video monitoring platform searches for the code stream before transcoding collected by the front-end acquisition device according to the identification information of the front-end acquisition device carried in the video browsing request, if the transcoder is found flow, execute step 103, otherwise execute step 105.

[0066] Step 105, when the CMS does not find the pre-transcoding code stream, instruct the front-end acquisition device to perform real-time video acquisition, and use the collected real-time monitoring code stream as the pre-transcoding code stream, and then continue to execute the steps 103 and 104, finally generate the transcoded code stream and send it to the client unit.

[0067] The following pas...

Embodiment 3

[0089] Embodiment 3 of the present invention also provides another monitoring video acquisition method, which can be executed by a client unit, and specifically includes the following steps:

[0090] The client unit sends a video browsing request to the video monitoring platform, the video browsing request carries a transcoding identification parameter, and may also carry identification information of the front-end acquisition device;

[0091] The client unit receives and plays the transcoded code stream sent by the video forwarding and distribution unit in the video monitoring platform or plugged into the video monitoring platform, and the transcoded code stream is based on the transcoding identifier Parameters are formed by transcoding the code stream before transcoding.

Abstract

The embodiment of the invention provides a video monitoring method, a video monitoring system and video monitoring equipment. The method comprises the following steps that: a video monitoring platform receives a video browsing request from a client unit, wherein the video browsing request carries a transcoding identification parameter; according to identification information of front-end acquisition equipment carried in the video browsing request, a code stream before transcoding acquired by the front-end acquisition equipment is searched for; the video monitoring platform transcodes the code stream before transcoding to form the code stream after transcoding according to the transcoding identification parameter; and the video monitoring platform transmits the code stream after transcoding to the client unit, so that the client unit can receive and play the code stream after transcoding corresponding to the transcoding identification parameter. In the embodiment of the invention, the video monitoring platform is used for performing uniform transcoding processing on each client unit, so that the normality of transcoding processing is realized.

Description

technical field [0001] Embodiments of the present invention relate to video monitoring technology, and in particular to a video monitoring method, system and equipment. Background technique [0002] Video Surveillance (Video Surveillance, referred to as: VS) technology refers to the technology that collects video information of each monitored location through front-end acquisition equipment, and then monitors the collected video information uniformly by the video control platform. Existing front-end acquisition devices usually use fixed code stream parameters to encode the collected video information. Therefore, when interconnecting with clients or other devices in the video surveillance system, different clients will use different code stream parameters, so transcoding processing is required. However, in the existing video surveillance system, the transcoding process for different clients is different, resulting in unreasonable system architecture, poor compatibility, high...
