Problems solved by technology

[0004] Although the above method can realize video monitoring, the security is not high, and it cannot be monitored anytime and anywhere
Once someone on the network intercepts video data and knows its encoding format, the acquired data can be saved and spread maliciously, which is a major hazard to the security of the industry; and for professional monitoring systems, only single-screen Monitoring is not enough, it is more practical to support multi-screen real-time monitoring without delay

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] With reference to Fig. 2, realize the system of video flow encryption in the present embodiment, comprise monitoring data acquisition device, monitoring front-end management subsystem, monitoring stream processing server, monitoring management subsystem, video playback subsystem, wherein:

[0035] A monitoring data acquisition device for collecting video data and outputting encoded video data;

[0036] The monitoring data acquisition device includes a camera and an encoder, and encodes the video data collected by the camera to the monitoring stream processing server. The encoded data is the output data of the monitoring data acquisition device, and the function of encoding is to compile the video data collected by the camera. The monitoring data acquisition device may also include a pan-tilt and a pan-tilt controller.

Abstract

The invention discloses a coding system and method of flow media in the professional monitoring system, which comprises the following steps: monitoring data gathering device, which gathers the video data to transmit the obtained coded video data to the monitoring flow process server; monitoring flow process server, which codes the received coded video data to obtain the flow media data; monitoring managing subsystem, which transmits the monitoring linking information of video playing subsystem to the video playing subsystem; video playing subsystem, which requests monitor for monitoring managing subsystem to decode the flow media data to play according to the monitoring linking information. The video playing subsystem receives he coded flow media data and key, which plays the decoded flow media data through the received key.

Description

technical field [0001] The invention relates to an industry monitoring system, in particular to a system and method for playing monitoring data in the form of streaming media. Background technique [0002] Streaming media technology is an online playback technology that has emerged in recent years. Online playback, as the name suggests, is to play while downloading in real time, instead of waiting for all the content to be downloaded locally before playing, but to play while downloading. Since people can watch real-time continuous audio and video online under low and high bandwidth environments, streaming media technology is widely used in information service fields such as online live broadcast, e-commerce, video-on-demand, and video surveillance. [0003] Existing video monitoring system as shown in Figure 1, comprises video collection device 1, video management device 2, video distribution device 3, after described video collection device 1 captures image, transmits to de...
